    Electric Dryer Voltage Problem
    Trouble shooting my clothes dryer …

    In checking to see if I have power, I used a digital volt meter.

    Hot leg 1 to Hot leg 2 reads 239V

    Hot leg 1 to neutral reads 96 V

    Hot leg 2 to neutral reads 143 V

    any thoughts

      Checking Dryer Voltage
      Hi Skip,
      Make all the Voltage Tests to the Ground Wire for the most revealing results.
      Typically, with abnormal Dryer Circuit Problems there may be a fault with either the neutral, or one of the hot legs.
      A higher than normal Voltage Reading on one leg is usually an indication that there is a Voltage Feedback which takes place through the Electric Heating Elements of the dryer.

      Key points to check for Dryer Circuit Problems:
      Dryer Circuit Breaker, including connections to the panel, the Dryer Receptacle, and the Dryer Cord.

      I hope this helps,
