    Fireplace, AC, microwave, water heater, GCFI no power

    Hi have a 2011 Big horn I bought used over a year ago and we live in it full time. Last night most of my power stopped working. At first I thought the GCFI had tripped but that didnít fix it. Then I checked all the breakers and fuses; all are working. Inspecting further I realized it wasnít just my outlet the werenít working. My hot water heater is out on electric but works with propane, my fireplace, bedroom ac, and microwave are out as well as my outside outlet which donít connect to the GCFI. Can anyone help me please?

    I would start at the park pedestal. Check the breakers there then using your multimeter check the power at the plug there. If you don't have a multimeter it's time to get one.
    If you don't have a shore cord reel check to be sure you are securely plugged into your rig.
    Do you know if you have a transfer switch? If so open it up and check the wires there.
    Did you reset the breakers in the coach. Don't rely on a visual for checking. Turn them off then back on. All of them.
    Circle back and let us know what you found.

    Peace

    I agree with Cookie here - sounds like you may have lost one leg of your 50A power service. Starting at the pedestal with a voltmeter then working your way into the rig is the way to track this one.

    If you are connected to a 30 amp RV electrical service, your 30 amp to 50 amp adapter cable may have developed a defect opening one of the 50 amp supply feed lines.

    If it was me, Iíd reset my system. Unplug from the pedestal, disconnect your batteries. Now check your voltages at the pedestal. Then turn on your battery power, then replug your electric is your voltages check out and you are assured you donít have an open ground, or neutral, and/or reversed polarity
