My first floor hall light, second floor hall light, and front porch light are all inexplicably out. All three of those lights are controlled by 3 switches on the same switchplate downstairs. Upstairs, there is a switchplate that has switches that control the two hall lights - so you can turn the upstairs and downstairs hall lights from the upstairs or downstairs switches.
All other lights in the house are fine. I have checked and switched on and off all the circuit breakers-even though none appeared to be tripped. I have checked and reset all the GFI outlets in the house (that I could find- there are 2 in the kitchen and one in the bathroom). All to no avail. Oh, and all the bulbs are working when I tried them in other lamps.
Did a little mouse chew through a wire in the wall? I sure hope not. If anyone has any ideas I would be so grateful.
