How Does a Ceiling Fan Speed Control Work?

If you’re worried about the summer heat, you know that you need a ceiling fan. It’s one of those multi-functional devices that can keep you cool and if you buy a ceiling fan with lighting, can also ensure that your surrounding is well lit.

While you can regulate it accordingly during the summers and winters, did you ever wonder how it all worked?

For instance, during the summertime, you would like your fan to rotate in the counterclockwise direction so that it will distribute that nice cool air through the house and create a soothing breeze.

Again, for the winters you would want it to operate in the clockwise direction because that will enforce the air to move-up and thus, all the hot air across the ceiling will be automatically forced down.

How Does the Ceiling Fan Speed Control Work?

The ceiling fan speed control requires some complex wiring for successful operation. The fan control allows it to rotate at various speeds and the working of the speed control largely depends on the type of technology used. It is integral to having proper wiring set up by a professional so as to be able to operate it without any hassle.

Many people think that it is okay to use a regular dimmer for fan speed control, but substantially it is not advised to do so.

The problem is that if you don’t get enough electricity, the fan won’t turn properly and will most probably get overheated- thus, resulting in a conflagration.

So, what you should ideally look for, in order to control the speed of your fan is a switch that is specifically designed for fan speed control.

The Two Types of Speed Controls

Coming to the type of speed controls – ideally, it is of two types i.e. wall control and unit control. The unit control usually has a prearranged setting of the usual ‘high, medium, low, and off’. So this way you can easily have the desired speed by operating the switch with the utmost ease.

The Dimmer Switch

It comes in the wall control category and allows you to control the speed of the fan by switching between high and low beams. The modern dimmer switches might be saving more energy, but there is a high probability of such a switch to be on the fritz.


The capacitors also play a vital role in its functionality as after receiving all the power from the source, it supplies the motor with a pertinent amount of energy which resultantly allows the user to set the fan speed at any desired level between off to the maximum.

The working of a fan’s speed control also depends on the fact whether your fan has a capacitor or a solid-state control. If it comprises of the solid-state control, then it will control the motor in such a way that it won’t make any kind of buzzing noises, which is otherwise generated by the motor’s windings. Additionally, it also has the necessary variable speed control setting.

Ceiling fans give a versatile look to your room as you can have the desired kind of lighting and additionally, it also saves a good amount of energy.
