Last week we had our first snow this winter. It's so beautiful out there. But after the snow, our Christmas light cannot be turned on. I checked the outlet, mounted on siding besides front door. It's not working. So I went down to my basemennt checking breakers. All of them are in on position. Anyway I just turned all of them to off position and back to on position again. Went outside and checked the outlet. It's still not working. So I decided to take out this outlet and checked wires, black and white, no voltage.
Now came the hard part. I tried to figure out which circuit is this outlet on. So I checked the nearest outlet and switch, which is located in my dinning room. All of them are working. There are three pair of wires connected to the switch. One pair in, one pair to front door light outside. And I don't know where does the third pair leads to because after I disconnected them, all other outlets and lights are still working.
Is it possible that the wire is burned out in the middle inside wall? If it is, how to repair it? We just had our house painted inside out this summer. Really don't want to open the wall to repair it. The house is about 15 years old.
Thank you in advance.
