Circuit Power Problems after a Power Outage
Electrical Question: We had a power outage and after the power returned my main bathroom light switch and exhaust fan will not work.
- I have tested the light switch and outlet with a multimeter and it has zero power?
- I have also reset all the panel breakers and even tested them and have 120 volt power from all of them.
I am stumped, please advise.
