Troubleshooting Electrical Home Wiring Problems
Background: Syd, a Handywoman from Las Vegas Nevada
Question: Recently I have troubleshot an air conditioner that has all of a sudden stopped working. It seems to have a 120V plug. Because there is 2 Furnaces to the air conditioner in the attic, i plugged the bad furnace into the good furnace’s electrical outlet and it worked just fine. Both outlets are on dedicated circuits but the one for the furnace i have been working on doesn’t put out enough voltage. I plugged a small appliance into the socket and it worked just fine. Can a Socket go bad? could it be a wire? or the circuit breaker itself?

Dave’s Reply:
Thanks for your electrical question Syd.

Syd, get yourself a good volt-ohm tester and you will then be able to troubleshoot just about anything. All of your questions can be answered yes, all of these things are possible however it will take a volt-ohm meter to find out exactly what is happening, you may have lost a neutral – lots of possibilities, and based on experience – its’ most likely always something simple!

    Recently added a ceiling fan in the master bedroom and at the same time switched out two flat panel outlets to the surge protected receptacles that are wired in parallel. All items are on the same circuit. At first the fan light wouldn’t come on. Pulled my splice apart at the switch, reconnected and light worked. At this time both tv’s and light/fan are working. All of the sudden I lost power to the light and both surge receptacles but breaker isn’t tripped. Can I have one surge receptacle feed another? I know it’s redundant but didn’t think it would hurt. Any thoughts?

    • Dave Rongey says:

      Because the surge receptacles are not feed-through wired and provide protection for each individual receptacle this should not be an issue.
      You may want to double check your wiring connections.
