    Electric side of water heater not working

    Electric side of hot water heater not working. I have 120v to the relay but nothing at the element. I have
    12v on the white wire to the control module. Should I have voltage to the yellow wire on the relay to trigger it? Any thoughts would be appreciated​. Gas side works fine

    If you’ve got 120 going into it and 12v at the coil I’d bet it’s the relay. It’s a pretty common failure. If it’s a Dometic/Atwood this is the part I put in mine.

      What model WH is in your unit?
