  1. shawn mcintosh says:

    my son plugged in and turned the vacuum on in his room and the power went off in his room and to one socket in the front room it happened once before and it eventually started working I’ve tried turning the breaker off on back on but didn’t but the breaker didn’t show its was blown any way so what should I do?
    THANKS

    • Dave Rongey says:

      Shawn,
      The outlet that the vacuum was plunged into may have a bad wiring connection, or a splice for that circuit may be going bad. The circuit should be turned off so the outlet can be removed and inspected. Repair of the affected wiring will be required, and or replacing the outlet.
