I spent a very frustrating day trying to replace a 3 way dimmer switch (main and aux) in my house with the GE 3 Way Dimmer Switch. It may be an issue with the directions or my wiring, so I’m hoping someone can tell me whether or not to give up and bring in an electrician (or that it won’t work my wiring) before I invest another day.
In the current setup, the main is at the top of a stair case and the aux is at the bottom.
In the main switch, there are 2 black wires (I assume hot and load), a bare copper (ground), and a red (I assume traveler). In the aux, there is a black wire (hot?, marked “common” on the current aux switch), a red (traveler), bare copper (ground), and white (neutral).
Wiring such that I ignore the black wire does not work (no LED lit in the main, no lights), similarly I’ve tried putting the black wire on the aux in line with the neutral and the traveller, but neither makes a difference.
My best guess is that the black wire is where the live in coming in.
I replaced the old switches and the lights work fine, so I didn’t break anything, at least.
Any help would be greatly appreciated, including pointers to a better product to use if this one isn’t going to be viable for this project.
