Hi all - i'm back from vacation and ready to finish this project that I've started. For anyone jumping into this now I'll give a very brief synopsis of what's going on ...
I replaced some switches in one of two bathrooms. After cutting the power to both of my bathrooms, when I turned the power back on at the circuit breaker I heard a loud buzzing noise. At first I wasn't sure where that was coming from but I have since narrowed-it down to the GFCIs in the other bathroom, the one where I made no wiring changes.
At one point I pressed the test button on all the GFCIs while the power was off. While the power was off it seems that when you hit the reset button nothing happens? When I tried again and turned on the power to these outlets I no longer heard the same buzzing sound.
Tonight I powered the circuit with the GFCIs again and if I hit the reset button on two of the outlets nothing happens. But, for the third pair of outlets (in the photo this is the ones with a lamp plugged-in) if I hit the reset button on this outlet the lamp turns on and then the buzzing starts. I quickly hit the test button to stop the buzzing noise.
Any idea what may be causing this? Or what I should try next? I have had no issues prior to cutting the power to this circuit. Previously all of the GFCIs were working and had their green LED illuminated.
