I'm having an issue with two recessed LED lights that are wired in-line. The power comes from a junction box (nothing else on this breaker has lost power, see below) down to a wall switch, back up to light #1 then on to light #2 (in the switch box the hot wires are attached to the switch and the white wires are attached together).
Three times now both LED lights have stopped working. Removing the LED units (these are he LED units that screw into a standard bulb receptacle in the can) and replacing with standard bulbs does not fix the problem and the LED units work within another system. I've changed out the switch twice and used a handheld tester to make sure power to traveling to the switch.
Twice now after fiddling with changing the switch and checking connections in the attic, the system suddenly begins to work again without an obvious change occurring. Typically the power will work normal for a day or two and then it stops again. Now after the third time, I have not tried fixing yet and the lights still do not work.
Nothing else on the same breaker is loosing power (a washing machine and four receptacles). The breaker has never tripped. I don't think it is too much power for the break; never tripped and lower power LEDS and I don't really use the receptacles apart from charging a phone and an 18 volt Dewalt drill battery. The wires are all new, I recently added the system when renovating a laundry room.
Any ideas what could be happening?
