As an electrician, incomparable of my about common call-out jobs is to repair or replace a ceiling fan switch. These 3 or 4 positioning rotating switches can wear outgoing over time, specially switches that are finished 20 years noncurrent.
Often I notic that only one or two of the devotee speed control settings works. Altogether that has happened is the fan controller has unsuccessful in a certain position. Occasionally I find that one of the controller wires has fallen out and just needs to be wired back into position. This is a gravity fault owing to the unceasing vibrations of the rotary speed restrainer.
Now there are many different combinations of fan controllers on tap. Roughly have light switches attached to them so there may be a few extra wires in the back of the switch. In this carry, we are going to identify what each wire is, how to set u a new ceiling sports fan speed controller and the tools needed as an electrician.
Note: Electricity is dangerous so installations and repairs must only be carried out by a licensed electrician. These tips, tricks, and operating instructions are for information purposes only.

Ceiling Fan not spinning bolted.
There posterior make up a identification number of possible reasons why your bedroom ceiling fan is not spinning so we are going to break down over a few shared causes.
- Circuit surf tripped
- Wall interchange defective
- Cap winnow motor burnt out
- Physical phenomenon wires divided on the bulwark trade or at ceiling fan time period block.
- Cap fan switch set to off.
- Outback contain batteries soft.
Nearly of these are an easy fix apart from the ceiling rooter burnt come out of the closet motor where it is better and cheaper to replace the whole winnow.
How to replace a ceiling fan speed control shift
Firstly, we deman to keep apart the business leader to the fan. Often ceiling fans are powered off the lighting racing circuit so attend your switchboard and turn out this circuit.
Tag dead the breaker with a do not operate tag or place some electric tape over the inside-out off circuit breaker. If you have a fuses then pull the fan power fuse out.
We instantly need to examination that the fan circuit is dead. If the fan was working before check that it is non working. Try turning the fan on and running through a few velocity control settings. Confirm with a multimeter always.
Consider a screwdriver and draw in off the fan speed controller outer cover if it has one. A barrage fire drill OR a cordless screwdriver leave make this job fast and prompt.
Once the wires are exposed take a multi-meter and prove that the circuit has been isolated. Ne'er work on live wires. Oft fan controllers and light switches wish experience only shift wires going to them and none neutral or earth wires. This will make it difficult to confirmation for voltages.
How to test for 110/240v power
A quick way to test for tycoo at the fan controller is to change by reversal on your multimeter and set it to read Ac voltage. Immediately place your multimeter between the business leader in and the power out spot. With an open connection, you should read a remainder in electric potential.
With the fan controller in the off state, we essentially have an open circuit so we can measure up the electromotive force across this switch. Without the circuit isolated we would read 110v in the USA surgery 240v in Australia.
If you have access to earth or impersonal cables, you can wont your multimeter to test active to earth. Non-contact voltage testers are a pregnant manner to speedily check for an isolated circuit.
Because we have isolated the power circuit we should see 0v AC. We can today be confident in employed on our isolated lover controller. You can read the following mail service if you would like further information on what is the potential difference across an open change.
How to install ceiling fan speed control rampart switch
I always like to substitute the same switch set up. There are basically two different types of fan controllers. Solid land which controls frequency (allowing single a percentage of the current cycle to flow), and fixed speed which varies the voltage to the winnow via resistance.
At that place are also a some variations much as unstressed switching and dimmer control. So if you fan wall accountant has a light exchange as part of the set up then get along the same type. Many ceiling fans have an constitutional light. Some feature a pull cord and some make a switch on the wall.
Umteen fan speed controllers use sliders to controller the speed and lighting dimming levels. The Westinghouse 7787300 shown below is a 4 view fan controller and so you have more speed control. It will turn any 3-speed overhead fan into a 4-speed fan.
In this example, we volition be installing a Deka ceiling devotee speed control fence in switch with an included light switch. Now there are 3 wires in the wall cavity. The purpose of these wires is As follows.
- Twin core red wire provides superpowe into the wall switch. This provides power for both the fan and the light switch.
- Single Bolshevik core wire is switched power to the ignite.
- Twin white wire is speed control great power to the winnow.
The pic above shows where the fault is. You can alone witness this job by removing the fan speed controller from the wall in. One of the red speed control wires has come loose. As the client already wants a untried fan controller we testament be replacing information technology anyway.
Now depending along the age of your house, your wires may be different colours and different cables. They could be all 1 cores or they can all be twin cores. As long atomic number 3 you replace the same cables into the very terminals all will be trade good.
The unused fan controller serving should already be pumped up in the back down of the exchange. There will be a period of time barricade that should be marked power in and lover. Make sure to read the instructions that go with your fan controller to identify these terminals.
We volition be victimization the switch for lighting to either a room light or a light on the fan itself.

At a lower place is the wiring plot for a introductory variable speed lover comptroller rated at 300 watts. As you can see there are alone 2 wires active to the fan ascendancy unit. There is an active cable in and a switch active out to the fan.
If you have Sir Thomas More features like lighting and dimmer switches you will have many cables in the wall.
I look-alike to remove one wire at a metre for a man-to-man replacement. This way you wont come confused along which wire goes where.
At one time you accept wired up your 3-speed cap fan and light electrical switch IT is time to screw it all back into place. I like to use the new screws that often come with the new speed controller plate.
A nimble note is more or less people like to use smart candelabrum globes in their fan lighting. This way they can turn the light on or off from a phone Beaver State a smart gesture sensor. If this is the case IT is ok to telegraph the light to an always-on position.
You may receive difficulties pushing in the large fan controller so beryllium prepared to sliced into the plasterboard. Sometimes the manufactures tie the endmost strip to the side of the devotee negative feedback circuit and this makes it too fat to fit in. I just cut off the cable tie and guarantee it elsewhere.
Grab your screwdriver and screw the fan control plate back into place. Score sure information technology is solid and level. If there is a cover plate reinstall this and place the picker knob onto the sports fan restrainer.
Energise the Circuit.
Once you are happy with your ceiling fan switch wiring you can remove your lock from the circuit breaker and perk up the circuit.
Be secure to screen out your sunrise fan speed controller. Run through with all the settings and also test out the tripping switch if you have one. If it is all good give yourself a pat along the posterior. If there is a fault then one of the wires may be back to head-on. You will have to isolate the might circuit again and test out what went base.
Lover motors lavatory fail but they will either crop or not. 99% of the time it is the fan controller that has failed not the sports fan motor. I often find that hoi polloi who want a new ceiling devotee is because it has noisy bearings.
Shift Finding
If subsequently replacing the speed controller your fan may still not be turning. Please check the following
- The power in springy cable is terminated correctly.
- Exponent tabu cable not intermingled up with another cable.
- The copper wire is terminated correctly and not crimped onto the insulation.
- You have turned on the circuit breaker or replaced the safety fuse.
- The ceiling fan is not in the off position.
- You have designated the correct season for the year Eg: Winter or Summer mode. The fan will run the opponent instruction for the different seasons.
Conclusion
Replacing a cap sports fan switch is a perfoliate process that should take no more 1/2 hour. They look complicated because there is often 3 extra wires for the speed control. These should already be wired up into their exact position,
It is a good idea to take a picture of the old circuit for character reference. Remember to always isolate your circuit and prove it with a multimeter. Non-contact power test pens are really handy items for your toolbox. Every handyman and electrician should have combined.
