Electrical Wiring in the Home/Dimmer Switch
Dimmer switch stopped working so I bought a replacement.
Replacement Dimmer: Has one green wire and two black wires
(which I will refer to as new green and new black)
When I pulled out the existing dimmer it had two black wires: One went to an internal red wire the other to an internal black wire.
My First Attempt To Hook Up New Dimmer:
New Green to Internal Red / 1 New Black to Internal Black: Did Not Work
New Green to Internal Black / 1 New Black to Internal Red: Did Not Work
New Green to Internal Black / 2 New Black to Internal Red: Did Not Work
Obviously I don't know what I'm doing but at least I shut off all power to house when working on this. Any help is appreciated,
The green is a ground wire, and goes to the bare wires in the box. If the house is old, and there are no ground wires, then it does not go to anything. But, once you short a dimmer, it usually does not work, so you will probably need to replace it. Either of the black wires go to where the old dimmer was connected. Green to bare wires in the box, or left disconnected.
