How to replace a dimmer switch?
â€¢ Turn off the power to the dimmer switch at the main circuit breaker or fuse box, and test to make sure it’s off.
â€¢ Unscrew the switch’s cover plate and remove it. The cover plate is the piece of metal or plastic covering the switch.
â€¢ Pull the old switch out of the wall carefully with your hand. Do not hold the metal parts of the switch as you do this. The switch should come out a few inches, exposing the wires.
â€¢ Unscrew the wire nuts connecting the wires coming out of the wall and the old dimmer switch’s wires.
â€¢ Take the switch to the hardware store and get another exactly like it – the same number of wiresÂ and the same kind of wire. If you aren’t sure, ask at the store. Also, make sure to get new wire nuts (this will ensure good splices when reconnecting wires).
â€¢ Match the two wires from the wall with the two wires on the dimmer switch.
â€¢ Firmly attach each pair in a wire nut. Make sure the wire nut is screwed on firmly and that no bare copper is exposed.
â€¢ Give each wire a light tug to make sure the wires are secured in the wire nut. â€¢ Mount the newÂ switch into the wall and screw the cover plate back on.
â€¢ Turn on power at the main circuit breaker or fuse box.
