Lately i ve noticed a few wifi smart switches being sold as fan controllers. Be aware that a standard light dimmer switch will not work with a ceiling fan. Even worse the ceiling fan motor could be damaged over time.

The wall dimmer switch reduces power flow and interferes with the fan control. Start by turning off the light and ceiling fan at the fuse box. Installing dimmer switches is a seemingly easy way to control a ceiling fan and or a lighting fixture. Converting a three speed ceiling fan to variable speed is even easier if the original fan was wired to a light switch to turn.

You cannot use a dimmer switch on a fan motor but you can find fan speed controllers why. Using a dimmer switch is not recommended for use with a ceiling fan. That works with lights but will burn out a motor and maybe burn down the house a fan speed controller is a much more complex electronic device that reduces the amperage to the motor without reducing the voltage avoiding this kind of innocent mistake. The more complicated answer we are engineers after all.

A wall mounted dimmer switch may be installed to control the ceiling fan lighting if the lights are compatible with the dimmer switch and there is a separate wire provided for the light fixture only. Watch out for regular switches being sold as fan controllers. It can have a big impact and be an inexpensive way to control the fixture. If your ceiling fan has wiring already in place where you have a separate switch for fan control then you can have the separate controls wired to independent switches.

There is a growing misconception that this is safe to do but the logic behind it is flawed. A dimmer switch for motor speed control can be installed with a few precautions and considerations in mind.

You may need an electrician for this.
