Electricity Saving Tips For Homes And Offices

Choose the right Regulator for Ceiling Fan for Electricity Saving

By on September 3, 2017

Ceiling fan is one of the most common appliances in Indian household. Being a tropical country, India relies a lot on ceiling fan and there is a ceiling fan in every room in the country. When we go and buy a ceiling fan, we also get a regulator along with it. Regulators are of different types, and different ceiling fans come with different types of regulators. Most people typically do not care about the regulator, but it is very important to know that even the regulator can waste electricity and can increase your electricity bills.

Good news is that you can always refuse to take the supplied regulator and can get equivalent discount, and replace it with an efficient one. But for that you need to know about the types of regulators.

How does a Fan Work?

A ceiling fan has an electric motor and metallic blades connected to it. When we switch on a fan, the voltage difference causes the current to pass through the motor and the fan rotates. The regulator controls the voltage that makes the current flow less or more. Lower the voltage lower the speed of the fan. So a regulator controls the voltage levels for the fan.

Types of Regulators

There are 3 types of regulators available in the market today: Electric Regulator, Step Type Electronic Regulator and Movable Electronic Regulator. All 3 have different ways of controlling the fan speed and thus the efficiency with which they manage electricity consumption differs. From price perspective Electric regulator is the cheapest, but of all three it is the most inefficient regulator. We are in process of compiling information related to price impact and will update that as well very soon. But first let’s look at all the three types:

Electric Regulator

Traditional regulators that were there in our homes in the past were mostly of this type. These regulators have resistors to decrease the voltage for the ceiling fan. The resistor heats up while decreasing the voltage and thus the electricity saved by reducing the fan speed is lost as heat in the regulator. The internal heat also damages the regulator in long run. These regulators are also bulky in size. They come for as low as Rs 40 a piece.ElectricRegulator

Electronic Regulator

Electronic regulators are the latest type of regulators available in the market. These are much smaller in size than the electric regulators. Electronic regulators use capacitors instead of resistors to decrease the voltage. Capacitors regulate the fan speed by regulating the waveform of power supply. These do not get heated up and thus save electricity when the fan is running at lower speeds (at higher speeds electricity consumption of fan is the same with both regulators).  These regulators save up to 40% at speed 1 and about 30% at speed 2 compared to electric regulators. There are 2 types of electronic regulators available:

    1. Movable Type: These regulators move smoothly and there are no stepped number (1 to 5) provided on theem. These regulators are better than electric ones but still can cause some distortion to the movement of the motor that causes it to heat up. This type typically costs Rs 100 apiece.MovableType
    2. Step Type: These regulators have numbered speed steps (typically 1 to 5). These regulators provide lower distortion to the movement of the motor and thus less heating. These are the most efficient type of regulator. This type typically costs Rs 200 apiece.ceiling_fan_regulator

If you run fans at low speeds in your house then a step type fan regulator is the best electricity saving option for you. Savings in electricity bills can recover the extra price you pay for it.

Please suggest me the brands of Ceiling Fan Regulators which work on the principle of switching of CAPACITOR Banks, but not the Triac based ones.

Abhishek Jain (Mod)

I mean capacitor based.

Abhishek Jain (Mod)

Anchor Roma, Havells are some good brands that have capacity based ceiling fan regulators. You can check them.


Can two ceiling fans be connected to a single Electronic step up regulator. If yes which regulator to use and if there is any damage to fan motor or regulator

Abhishek Jain (Mod)

They can be but then you will have to connect it to same switch as well and then they will operate together at same speed.


Thank you very much for this article. I am facing a problem which is giving me and my baby not good sleep. I have step r egulator. The problem is that at step 2 the fan runs very low speed and at step 3 the fan runs very high speed. The speed difference between 2 and 3 huge. Is this because of step regulator problem or fan problem? what needs to fixed ?

Abhishek Jain (Mod)

Try changing your regulator. It is a problem with the regulator.


resistant type fan regulator


Any one can clear that power of new 90 watt and 5 yr old 90 watt fan is same.


What about digital fan regular? How they fare compared to electronic regulators?


I've 7 ORTEM fans in my home, all equipped with electronic stepped, branded regulators. The problem is that all the fans run very low speed at 1-2-3-4 and very high speed at 5. Pl suggest, where the problem could be?
Is it with the regulators or the fans.?

Abhishek Jain (Mod)

The capacitor in the regulators has gone bad. This is a very common problem with electronic stepped regulators. Even with the branded ones.


I want purashes ur old model elcotrinc. Regulatior. From where


one year back I have purchased O general Inverter split A/C of 1.5 T with cut-off box(V-guard). For the last one month I am facing a problem.i.e. the Electric fuse at out door unit is getting blow out. when I call the service person , he told me that the incoming Voltage from the main is 243V, hence the fuse getting blow out and he also further clarified that the cut-off box will serve only when the Voltage is as low as 230V and as high as 270V. But the incoming Voltage is neither below 230V nor above 270V , hence the fuse is blowing out and breaking the power, Where as TS transco Personnel saying that 243V is common voltage. In this situation what i have to do? Please advise me with a better solution to get rid of this problem immediately.

Abhishek Jain (Mod)

Which VGuard stabilizer do you have (can you provide model no)? Because every stabilizer has operating voltage range and typically 243V is there in the range of almost every stabilizer. And it should work in that case. I think the Stabilizer itself is faulty as it should stabilize the voltage if it is above 230.

Hanumantha Rao Ramaiah

Today the 16th April 2017, I went to bed at 11.45pm and went on deep sleep after tuning the ceiling fan to medium low.

I was sleeping in the last corner room and the switch board just one feet above my head.

At 2am night....

My grand daughter noticed rattling fan sound and alerted me seeing full cloud of smoke inside the building.Immediately I switched off the main supply by that time switch board cought fire and molten plastic falling on the bed....Just 10 second delay would have caught fire on the bed on which I was sleeping....great escape for me.......:) Inhaling the heavy smoke created head left side and left cheek developed unusual pain..

This is due to heating up low cost fan regulator which heated up supported by summer temperature. I recommend all users to use reliable electronic stepped up regulator which does not heats up and saves power also.

Hanumantha Rao


Ceiling fan in my hall runs on a constant speed 1 that is very slow and even on speed 4 it's the same as speed 1 it only runs fast on speed 5. Can u tell me what's the problem behind this and what should I do for it ????

Abhishek Jain (Mod)

The problem is with the regulator. The electronic regulators with capacitor do get such problems. You will have to replace the regulator.


Can you pls suggest something that controls the fan speed well. Almost, all I used either run too slow or too fast. Mostly 5 speed ones whether Havells, Crompton, etc.
I am not interested in saving electricity bills on a fan.

Abhishek Jain (Mod)

Hi Swaroop,

As far as regulator is concerned, we have not found any brand that is good enough to last long. Most electronic regulators have this problem of either too slow or too fast. You will have to switch to old big bulky resistor based regulator if you want consistent performance.

Now about saving electricity bills on a fan is concerned. I would say if you do not use an AC, fans are the most electricity consuming appliances in any house. A typical fan of 75 watt if run for 12 hours would consume (75x12)/1000 = 0.9 units of electricity. Put 5 such fans and we are talking about almost 5 units of electricity per day. Compare it to a refrigerator that at max uses 3 units, or a geyser that uses 1-2 units of electricity, or all lights (5 tubelights of 50 watts used for 5 hours = (5x50x5)/1000 = 1.375 units), we understand that fans are THE MOST ELECTRICITY CONSUMING appliance in a house.

As far as regulator is concerned, I know it is a bit of nuisance. But the other alternative is to switch to BLDC based energy efficient fans (30-35 Watt fans) that operate from a remote control and do not use regulator.


hellow why regulators gets hot when the fan rotatehellow why regulators gets hot when the fan rotate

Abhishek Jain (Mod)

Ceiling fan regulators are either resistor based or capacitor based. They are used to change the input voltage to the fan. In case it is resistor based, it will get heated when the current passes through it.


hellow why regulators gets hot when the fan rotate


Hi Team,
Can you list some of the TOP ten Fan regulators manufacturers in India which are leading in Quality products, and capture major portion of Market.


Abhishek Jain (Mod)

Hi Kuldeep,

We do not have data to make an objective comparison. I have personally used Anchor and have heard a lot about it. It is a good brand.


Hi Abhishek,

Thanks for your feedback.
I was trying to calculate the total Market size in India for Fan Regulator, and who are the major Brands manufacturing them. As per my Understanding, All Fan manufacturers are using the OEM for such products. Since i came across your website with such good intraction, i thought i will take your expert help to have a understanding on this.


Abhishek Jain (Mod)

Hi Kuldeep,

I am sorry we do not have the data that you are looking for. Currently our priorities are limited to bigger appliances and we have not been able to focus much on other things.


Hello Team,

If I keep regulator at 3 instead of 5 Always, does it mean that I will get less electricity bill because I maintained regulator at slow speed??

Could you please help me?

Abhishek Jain (Mod)

Certainly. A fan consumes less electricity at speed of 3 than at speed of 5.


Need your advice, as we have been getting this constant humming noise from a ceiling fan, operated from one floor down neighbors.
We have checked the fan, along with an electrician & even got the fan replaced, but this humming noise stays, the moment they switch on the fan.
Fan is hanging on the "U" shaped iron bar, which protrudes out from the ceiling & provided/ built by the builder.

Pls suggest.



s there a rubber pulley between the Fan and the U shaped iron .bar?

Many people remove the Rubber pulley because of size differences.
This is the cause of the Humming noise.

Abhishek Jain (Mod)

Missing of this rubber could be the reason for the noise.

Abhishek Jain (Mod)

Hello Mr Manoj,

Can't really say what is happening. It may be because of the U shaped iron bar. But I am not sure.


Is there a rubber pulley between the Fan and the U shaped iron .bar?

I have bought dimmable LED bulbs. What type of dimmer / regulator should I use to dim LED bulbs? I mean step less or stepped electronic or something else?

Thanks in Advance


Hello Bijli Bachao team,
I appreciate your effort for writing this very good article on fan regulators. But you seem to forgot one type electric regulator, which is called choke regulator. Regulator consisting a choke is very effective for an AC fan speed regulation. Choke coils have low resistance and high inductance, so when AC current passes through choke coils a small percentage of current is lost as heat, most current flow is just blocked. But for regulators with resistance coil current is lost as heat. In good old days good AC fan manufacturers (like orient, cinni, khaitan most probably GEC and Crompton Parkinson) used to provide choke regulators with ceiling fan

In choke coils AC current form is not distorted (this save fan motor from over heating) which happens in cheap and medium quality electronic regulator.
So if I am allowed to rank regulators considering all parameters like efficiency, goodness factor for a fan motor, RF noise etc then

1) High quality stepped electronic regulator (BEST)
2) Electrical choke regulator
3) medium quality electronic regulator
4) Regulator with resistance coil
5) Cheap electronic regulator (WORST, this type will damage motor in long run, will cause RF interference with AM radio and other sensitive electronic gadgets)


Hello Anjan Banerjee,

I have noise issue with the fans at home, it makes loud sound on low speed and when on ups even if the fan is on higher speed it sill starts making sound. With another fan in the hall is making loud sound on high speed and this a new fan. I'm getting going through real bad time at home due no proper sleep due to the noise from the fans. What causes these issues and can u please suggest solution.


Hello Ray,

I presume that you have installed continuous speed variation type electronic regulators for your fans. In USA these are called light dimmers, and as their name suggests, they are only certified to use in light-bulb circuits. These can efficiently dim incandescent bulbs and halogen bulbs. Recent change from incandescent from LED and CFL had problems. Now there are two types of LEDs and CFLs sold in market; one is dimmer supported and one type is not for dimmer circuit.

Now back to your problem, Directly connect fan with switch bypassing the regulator. If that stops humming noise completely then check that does your fan regulator has continuous speed variation? then remove it from board and check for word dimmer at the back of regulator, or the package in which it came.If you see these replace them with capacitor (cap) based fan regulators. With cap based regulators humming problem should go. Cap based regulators also save energy, (for example one of my fan (1400 mm) consumes 70 watts at full (speed 4), 40 watts at 3, 25 watts at 2, and ~10 watts at 1.)

I have seen some dimmers with stepped variations so be careful about that, dimmers cost 75/- - 120/-, where as capacitor based regulators cost 150/- - 350/-. I prefer Havells & Anchor, you can select different brand too.

Why motors hum with dimmers? Because of AC phase angle alteration and because of switch on-off to chop wave portions from AC input. This results in humming and overheating of motors. For long run, capacitors die early, bearings dry out and coils are fried. Old fans had thick shell so they hum less or may be inaudible but new fans have light and thinner cover so they hum loud, but damaging effect is same for both. So , electronic dimmers are not suitable for motors.

One thing to mention is capacitor based regulators available in market are only suitable for ceiling fans and for fans below 100 watts. Also speed regulation (RPM) varies through fan models. Capacitor based regulators are always stepped and have only fixed 4-5 working speed.

Your fan hums on UPS because UPS output is not AC (your tubelight magnetic ballast should hum also), rather it is square wave aka trapezoidal waveform. You have to change your UPS with a sine-wave inverter UPS. Sine-wave inverters modifies square wave to near AC wave form.

In rare occasions, your fan might be defective, like loose coil wrap or armature/rotor loose fit. If you fan hums directly on AC line (that is bypassing regulator, switch to fan, no regulator in between) then your fan might be faulty.

Let me know whether this solved your problem.

Abhishek Jain (Mod)

Hello Mr Banerjee,

Thanks for the information. We will certainly do more research on it and update the article.


Hi , I have a crompton grieves fan,my electrician brought a regulator which has step type seven speed regulator it is working upto 5 speed only, 6,7 not working fan switching off ,is there any problem can you please suggest me regarding this.


Your regulator is bad, just replace it. Go for a reputed company.

Abhishek Jain (Mod)

Hello Prems,

A regulator just varies the voltage and the speed of the fan adjusts according to the incoming voltage. So ideally if your regulator is changing the voltage at 6 and 7, then it should certainly work. I do not see any reason for it to not work. Your electrician should be able to check out the reason why it is not working.


Earlier my fan had an complaint. . I don't know what is it complaint. .
Whenever I turn on the fan the circuit got tripped..
But oneday it worked for about Some time and then again tripped..
Some say winding problem. .
Some say problem of starter or capacitor. .
I never showed it to any technicians. . I want to try reparing it myself if possible. .

Abhishek Jain (Mod)

Hi Rijo,

It is extremely difficult for us to tell you what can cause the problem sitting remotely. A technician would be the best to find out the problem for you. So would suggest you to take it to a technician.


Sir I have some doubts in electrical wiring. Can I ask them

Abhishek Jain (Mod)

What is it that you want to know?


Thanks for your valuable msg. I replaced it with a normal regulator. . It
costs me about 100 rs only..


Sir I have a doubt.. plz reply my orient fans regulator got damaged. . Can I replace it with any other brand regulator. . And also Can anyone explain the connection or wiring diagram of fan switch to regulator to fan...
Can anyone reply to [email protected]

Abhishek Jain (Mod)


You can replace it with any other fan regulator. It should not be a problem. However we do not have the wiring diagram to connect the regulator.


Dear sir

I am just 17 years old. I ask question to you when I on the fan on 1 speed. And then I on the fan on 5 speed.so both of result same or different? ? Please give me answer

Abhishek Jain (Mod)

Hi Keyur,

Did not understand your question properly. At 1 speed of fan will be less and at 5 speed will be more.


Electricity bill is same or different


Sir I mean lowest speed and fastest speed.on regulator 1 is lowest speed and 5 is fastest speed.

Sorry sir but I am a student so I can't present right English clearly. Just little mistakes in my writing so I apologise.

Abhishek Jain (Mod)

Hi Keyur,

Electricity bill will be different. You can check the energy consumption numbers at various speeds on this link: https://www.bijlibachao.com/fans/review-superfan-bee-5-star-regular-fan.html


I have 4 Crompton Greves (Model-High Speed) ceiling fans. The fan runs at very speedily even at level 1 and thereafter runs very fast at each level. Sometimes the speed gets unbearable for us specially during Rainy and Winter seasons. The regulators are not from the Crompton Greves.
Please suggest some solutions for this problem.


Namaste Rajeshji,

I had same problem as you discussed previously.
I installed two step regulators in series for one fan, to reduce the speed of fan.
Currently it is working nice, let us hope for good long term returns.

Thanks & Regards


I've 4 electronic step type and 1 electric regulator in my home. Electric one is working fine while all the other electronic have problems of very low speed at 1-2-3-4 and very high speed at 5. After reading the comments here I learned that lot of people are facing these problem. I think either these regulators are of bogus quality (including branded regulators) or there is a problem with this technique of regulating fan speed.
We have sent satellite to Mars, can't we have a good fan regulator.

Abhishek Jain (Mod)

Hi Rom,

It is the capacitors that have lesser life. Unfortunately that is a problem with best of brands.


Are u trying to say that the capacitors in the fan regulators have malfunctioned due to age? If yes, then how will u explain this exact phenomenon in the newly bought and installed fan regulators in my house?

Abhishek Jain (Mod)

The new ones should have warranty. And if they have failed, then you should get them replaced. What we mean to say is that capacitors in regulators fail and thus they become ineffective in regulating speed properly.


Hi, I am using Orient wendy fans with Step Type electronics regulator. My both fans can not speed up in level 1,2, and 3. On level 4 they rotate at high speed. But in level 1, 2, and 3 they both are running at too slower speed. First 3 level can not make difference in fan speed. I also have contacted technician. But technical suggest us to use old Electric Regulator. What should I do? I am totally fainted with technician's suggestion. Please help.....

Abhishek Jain (Mod)

Hi Hiren,

The step type regulators are efficient however they are not very durable. And this is a common problem with these regulators as the capacitors go awry most of the times. Old Electric Regulator works well with the speed but it is bad for electricity consumption. So I am sorry to say but one has to choose between either evil. Or move to brushless DC fans that work with remote control.


The problems is only with Orient fans. The same regulators are working well with USHA fans in my house.

Abhishek Jain (Mod)

Then you must call up Orient so that they can send their engineers to check the same. It should not happen that one brand fan is working properly and other is not on the same regulator.


I too have Orient PSPO Fans and step type electronic regulators and after having replaced all regulators periodically not even a single regulator has been able to sustain for any long.
Do you mean the step up electronic regulators are a FAILED TECHNOLOGY and still being allowed to sell by Electrical authorities in the country and there is no quality control mechanism ?
Moving back to older technology of electric regulators that work on resistors is not a practical option as most homes do not have space in the board nor is it updated technology.
Regulators are meant to regulate speed for our comforts and not that we align our way of living as per capacitors wishes.
We expect a solution through this medium, else whats the point in having such forums online to just accept what is thrown by these vendors at us.


Hello Bipin,
Capacitor (cap) based regulators are not failed technology; rather cap based fan speed regulation is very useful method as it saves energy. Problem with Cap regulators is that they are generalized over manufacturers and different makers have different parameters for their motors. So some motors might work well and some might run slow, which is neither fault of manufacturer of regulator nor fault of the fan manufacturer.
Premium fan models from Orient electric have inbuilt cap based speed regulators, which works better for their fans because they have preferably selected capacitors of suitable capacitance ideal for their fan motors.

Some of us often run fans at slower speeds, thinking that will save motor, and some of them always prefer to run fan at slowest speed. But I must mention that AC induction motors are 'single speed motors' and are 'happiest at their highest speed'. But, for AC fan motors, we can reduce speed without much worrying, as these are much more forgiving (current draw is little). As we slow down speed of AC induction fan (ceiling, table, pedestal, wall, exhaust fan) motors (using common regulator technologies like resistor, inductor, capacitor or even TRIAC based dimmer), slip increase, torque drops, and motor efficiency also drops.

But, DC motors and universal motors are happy with slower speeds. Universal motor speed can be effectively controlled using suitable TRIAC based dimmers (i.e you have to use a dimmer that can provide 1000 Watts to control a 500 watt motor).

AC induction motor speed can only be altered using variable frequency drive (VFD), which is very costly. Only VFD maintains efficiency and torque with speed variation.
BLDC fan speed can only be varied with the provided remote. Never attempt to reduce speed of BLDC fan motors using external regulators, as this might permanently damage your fan.


Hello Anjan,

I have bought dimmable LED bulbs. What type of dimmer / regulator should I use to dim LED bulbs? I mean step less or stepped electronic or something else?

Thanks in Advance

Abhishek Jain (Mod)

With LED you can use step less regulator. That would be better.


Abhishek - I tried with step less regulator to dim dimmable LED bulbs, it works to some extend and then starts flickering if I want to reduce it below certain limit.
How different stepped regulator from step less? I mean stepped one also chop off part of sign wave? or it works differently?



I am guessing I have the capacitor based regulators installed (they are not the older big protruding box type but small ones the same size as the switches themselves built into the board and the dial turns freely instead of in 'clicks' and speed of the fan is changed accordingly. Interestingly I found that it works with superfan also. The way I realized was that one day the knob was turned all the way down to 'zero' position and the fan won't work at all - I didn't notice it and I started worrying that my superfan, which I bought against the wisdom of my family members, has failed me. Then I noticed the knob and turned it to 'full' and thank goodness the fan started working again.

Secondly, I have a query based on a mistake made when the house wiring was done. In one of the bedrooms, the regulator is connected to the tubelight point instead of fan. So when I turn the dial, the tubelight (regular 36W T8) starts dimming and after a certain point it turns off. I am thinking of replacing this with an LED tubelight shortly so is it possible to continue using that regulator as a dimmer? Would I be doing any harm to the LED tubelight or any of it's components? Is there any difference between using this one and an actual dimmer?

Abhishek Jain (Mod)

Hi Uday,

Firstly Superfan company suggests to remove regulator for their fan, so I would recommend to get it disconnected. We have done the same in our house. It is better that way.

Regulators job is to reduce voltage and that is why when you move the regulator for your tubelight, the output of tubelight becomes low as the voltage is low. LEDs are available in dimmer compatible and non compatible versions. If you want to use them with Dimmer then you will have to go for dimmer compatible versions. With others there can be flckering or buzzing sound (or both). Luminaires will work as long as the voltage is sufficient enough to make them work. Once the voltage goes below, they will stop working (as it is happening with your current tubelight). Regulator and Dimmer are essentially the same. They regulate voltage.


We have new ceiling fans in our home, there is step type regulators installed for each fan. At no. 5 these fans runs fast but at no. 4 they go very slow as if they are being run on no. 1 or 2. we have tried changing the regulator but of no use. Pls advise as it causes very discomfort to be in Very fast air when not required

Abhishek Jain (Mod)

Hi Sakshi,

It is a problem with the regulator. Most modern capacitor based regulators fail very quickly. They are energy efficient but not very durable. Old resistor based one were long lasting but not very energy efficient. Another solution is to move to newer BLDC super efficient fans that have a remote control to change speeds.

chandan chakraborty

just take 5 fan regulator step electronic type but in lower speed all the fan causes roaring or you can say humming sound , what to do please specify..


I have brought a high speed ceilling fan. is it safe to Controlling it with Step Electronic regulator?

Abhishek Jain (Mod)

It is certainly safe to use step electronic regulator with a high speed ceiling fan.


Hi Team,

I have recently purchase online an Ovastar Hand Blender-Mixer (OWHM-1014) most possibly china made, Delhi marketed. This has 5 speed settings probably field or winding tapped universal motor with carbon brushes and o/p 250W. I have used it a few times to make cakes and cookies and found that the RPM of speed setting 1 itself is so high, that there’s very small variation of RPM in other higher settings (one can say hardly any difference between speeds 1 to 5. I’d like to reduce the speed at point 1, 2 & 3.

Can you advice if adding some resistance or inductance/capacitance or triac-diac in the speed controller’s circuit points at 1-3 would help regulate the RPM of the motor to desired level? Or can I use regular ceiling fan regulators available in the market?


Abhishek Jain (Mod)

Hello Mr Bhalekar,

The alternative you have given will certainly help in reducing the speed at level 1 and thus you can get higher speeds at point 2 and 3. But unless one know the complete circuit, it will be difficult to guide you on this. You may discuss with mixie mechanics and may get the desired adjustment. Use of regular ceiling fan may also help but better if you take to the mechanics undertaking such epair work for the correct adjustment and check on the current drawn at each setting within limits. Please share when get the desired adjustment so that it will benefit other visiter on the web site.


I am using capacitive type regulator.1.1 MFD,2.2MFD 3.3MFD capacitance are using.But variation in speed is too high.All five regulators have same problem.Can I increase the speed by increasing the capacity of the capacitor.

Abhishek Jain (Mod)

Hi Vinay,

Capacitive type regulator are quite efficient, however we have not seen any regulator of this type which does not get problem after sometime of use. So this is a persistent problem with this type of regulators. We mostly recommend people to change the regulator in such case. Or we recommend people to move to brushless DC fans available in market (like superfan or orbit greens fans) that use remote control to regulate the speed.



I have five fans and all are working with step type electronic regulator(GM).The problem is while it is working in speed 1,2,3,4 the speed is very slow.But in speed 5 it is ok.How can I increase the speed in1,2,3,4.

Abhishek Jain (Mod)

Hi Vinay,

It seems your regulator is not working properly. You may have to replace it.


I m sufferin from the same prob as ayesha n hence want to slow down the speed of the fan at step 1 itself.. It wud be really helpful if u hv a suggestion to our prob...

Abhishek Jain (Mod)

Hi Aashana,

You will have to get the regulator changed for that. Speed at 1 is fast only when the regulator is not working properly.


The older model regulators fail less and are more reliable. We changed nearly half a dozen electronic regulators in the past 4 or 5 years. None of them gave a consistent fan speed either. The fan either ran too fast or too slow. So much for 'modern technology'. Every year, the quality of 'new technologies' seems to be so terrible it feels like it can't get any worse - however, manufacturers consistently disprove our contention by making their newer models even worse.

We recently switched back to an old model regulator for two of our fans. The speeds are more consistent now. We will (most likely) change the other electronic regulators once they fail.


Yes, I also tried a lot of movable and step type electronic regulators for more than 5 years, they really did not give better performance than the old generation electric regulator, they also died soon.

3 years ago I decided trying old style electric regulators and I am happy with my decision. They perform better (No humming sound at low speed) and predictable results at every level. They do what they are supposed to do and none of the regulator has died in last 3 years.


Can the minimum speed of the fan be reduced?I mean can changing a regulator help to start the fan at a slower pace than what it runs now?the starting speed itself is too much n we now have a small baby n can't run a fan at such speed..pls advise.

Abhishek Jain (Mod)

HI Ayeesha,

The speed of the fan depends on voltage that is supplied to the fan. Regulators change the voltage. So certainly speed of the fan can be reduced. Typically it is quite low at 1st step of the regulator. Is it not changing when you move the regulator?


Thank you for the response...I'll get the regulator changed.

Typically it is quite slow in the beginning right?but ours is fast at the start itself n it only gets speedier.... Hope it slows down.

What do you want to know about it?


how we install a step type regulator

Abhishek Jain (Mod)

You should take services of an electrician to install the regulator for you.


I have stepped electronic regulators for ceiling fans in my house. My problem is that the speed of the fan becomes erratic after few months of installing a new regulator. I have to change regulator every 6 months to 2 years. Can't we make good, sturdy regulators in India. I have tried brands like Anchor & Straco.

Its a common problem with regulators. It's not a problem of Fans. Other option is to switch to Supefan (http://www.superfan.in) which does not need regulator.


Thanks. At last I have an authentic answer.

Hi Rajeev

(There's no reply tab below your response, so typing here)

Thanks for your insight. Yup, that's how these guys make a killing. But I'm still experimenting. I'm hunting for capacitors that are attached to the back of the circuit board of the regulator. Just a hunch, not sure that's the issue.

I'm just baffled by what part exactly is spoiled "beyond repair" - I want someone to point out what the spoiled part is, rather than just give me universal (albeit blind) advice of just buying a new one. The d*mn thing can fit into a kid's hand, yet noone knows why it's not working as intended.

You're right though. Only the manufacturer (probably Chinese) is to blame - they know the problem.

Will let you know if the capacitor change works.



Hi! Suhan, I agree with you. I am sure that a knowledgeable person should be able to fix the problem either in the circuitry or the capacitor.


Hi rajeev . .we have the same problem . . had to change all the regs in my house twice! . . .and they still keep failing within 6 months . . .i've gone to a dozen shops, and although all of them suggested that it they cant be repaired and that i have to buy a new one, none of them actually could give me a convincing reason as to why they fail . . .

did you come up with a solution?


Hi! Suhan. I have no solution so far. I feel the component quality is to blame. Sellers get high commissions on such product and seem to be interested in handing you a new one. But that is how our economy works I guess. I would lay the blame on manufacturers rather than the sellers. An interesting information on this forum was regarding "Superfan" which does not require a regulator and is operated by a remote.It is being made only in one facility, probably in Karnatka. They accept order in bulk only. This discouraged me, as issues of warranty and couriering the unit to the factory would have been too much of a bother in case of defect.

Best Wishes



if fan regulater slow point, then what will be current flow and what will be electric charge?

Hello Mr Patel,

It is wrong to say that electronic regulator uses capacitor to regulate speed. Speed is regulated by triacs which cuts waveform as per setting of variable resistance. These regulators distort waveform of current causing humming sound in fan at lower speeds. Best regulators were auto transformer type which are not being made now a days being bulky and expensive. Auto transformer do not consume electric and do not distort wave form power saving is real at lower speeds.


Hi Abhishek,

In my new flat, builder has installed 6 legrand electronic stepped regulators. All of them are having same issue like for first speed, fans runs fine but on 2nd speed fan changes its speed drastically which gives feel as speed of 4. And this is happening in all flats of the building.

what can be the problem?

Abhishek Jain (Mod)


I would try with the regulator first. The speed of fan varies as the voltage varies and the job of regulator is to change the voltage. If the regulator is not able to change the voltage effectively, speeds will not be consistent. Try changing one of the regulators with a new one.


What type of problem is encountered in ceiling fan when electronic regulator

Abhishek Jain (Mod)

At times electronic regulators are not able to vary voltages properly and as a result of it the fan runs at similar RPM at multiple speed levels. For eg it may run at fastest speed at setting of 3,4,5 and may slow down only at 2 or 1. Or it may slow down from 5 to 4 to 3, but may not slow down further at 2 and 1.

anil chodankar

at present i have small regulator which gives to much of noise, when i put fan on slow. I have inquired in the market for old rugulator but it is not available. wiil u please guide

Abhishek Jain (Mod)

Hello Mr Chodankar,

Noise is coming from the fan or from the regulator?


Hello Abhishek,

Two ceiling fans in my home recently have same problem. They run at slow speed from 1 to 4 but very fast at 5. Both have step type electronic regulators. what might be the problem?



Abhishek Jain (Mod)

The problem is with regulator. You might have to change it.


why do regulators of fan gets heated?

Abhishek Jain (Mod)

If it is a resistor based regulator, then when current passes through a resistor, heat gets generated. It's like when tyre runs on road, it gets heated.



Can a ceiling fan with electronic regulator be operated by two 2way switches ?

Abhishek Jain (Mod)

Yes, they certainly can. We have such a setup in our place.
