The ceiling fan lights will be off and the fan blades will stop turning when you turn off the correct breaker.
Can you use a dimmer switch on a ceiling fan.
3 hold a noncontact voltage tester against the ceiling fan wall switch cover plate.
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.
1 400 people are injured and 500 die from electrical fires each year so make.
A fan that has no speed control when manufactured has copper windings inside that determine speed and horsepower.
A regular dimmer switch simply reduces the voltage.
You cannot use a dimmer switch on a fan motor but you can find fan speed controllers why.
A safe repair can be as simple as replacing the dimmer switch with a standard toggle switch but you also lose the ability to dim the light.
Never use a standard dimmer switch or unchecked wires to hook your ceiling fan up to a dimmer.
In this circumstance the light kit could be connected to a dimmer switch and the fan motor connected to a toggle switch.
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.
If the wiring for a ceiling fan is already in place in your home ie you have separate wires for the fan control and the light control it should be fairly easy for a qualified person to wire up separate controls for the fan and the light which will.
It is always better to be safe than sorry especially when electricity is involved.
