Okay. We have one outlet in the living room that doesn't work. There's also another in one of the bedrooms that suddenly went caput. Everything else works. We thought it might be the outlets, so we changed them out. Nada. Everything else on the breakers in question are fine. There are only two wires in said outlets, but before, with the one that just stopped, both outlets worked.
Any ideas on 1) what's wrong and 2) how we can fix it. Hopefully without having to open the wall or call an electrician!
