Have a 2-gang light switch in bathroom. Left switch controls vanity light. Right controls bathroom fan+light. There is also a GFCI outlet in a separate gang that may be tied into this somehow? I'm not 100% sure, but it is very close to the switches.
This was working. I swapped out the GFCI and tried to swap out the right light switch for fan+light simply because they were old and yellowed. Well, I broke it. How can I wire this correctly?!
There are 3 pieces at play here:
- Furthest left light switch in 2-gang. This controls vanity light I believe and appears to have two black wires on the right side. The top black wire was branched off to the right light switch (uncapped wire), and the bottom black wire appears to come from the wall. There is also another uncapped wire that was connected to the right light switch coming from the wall.
- Right light switch. I believe this controlled the fan+light. The original switch had an input labeled "common" but I have no clue what wire went in there. Also it appears the original switch had more inputs than the switch I tried to replace it with. Maybe that's how I screwed up?
- The GFCI is in its own gang, about 12" to the right. This seems to work ok, but the test and reset buttons don't actually seem to do anything. The weird thing about this is when I was replacing the previous GFCI outlet, I'm not sure that both black wires were even connected. I know the white ones both were. But there may have been a black wire (the bottom black) just uncapped and not connected to the previous GFCI outlet. Or maybe I'm imagining things.
I tried many ways of wiring this, both with the new switch and going back to the original switch, and each time I turned on the breaker, the GFCI indicator LED would light up, but neither light switch would work. And when I took the electric tool to check for current, it wouldn't even beep that current was even running through the light switch wires. So I am at a loss here...please help.
- Do I need a different light switch to replace the existing one?
- I only have 2 black wires + ground to play with, so how did I mess this up so badly, and where do I connect those two wires?
