Sometime this evening, all power went out in one room (outlets and overhead light), plus one outlet in the hall and one unswitched outlet in another room. I checked the breakers, yet the rest of the circuit works, as well as other outlets and ceiling lights attached to the same circuit. I have a tester, and have mapped the outlets that are out, but this is really strange to have some working and some not. I will check more in-depth in the morning, and check the wiring in the attic.
The outlet in the other room that doesn't work is only malfunctioning on the non-switched side. The switched part of the outlet works fine and tests fine on the tester. The light switch and light that works the switched part works fine too.
I've checked all GFCI outlets and they are fine. The house is 30 years old and I've been replacing worn outlets periodically, but it's been three months since I have done any electrical work on the house. We've been here seven years and haven't had a problem like this.
I have a decent understanding of electrical wiring, but I am not a professional. I wonder if a critter got into the attic and had a bad evening, or if a bad outlet led to the others failing. Any other ideas?
Thanks for any help. I'll check the wiring in the morning and the suspect outlet, then call a professional if I don't find anything.
