fridge not staying on (faulty circuit board ?)

I have a Domestic 3-way fridge that will only stay on for a few minutes whether I put it on ac, battery or propane. One of the locals said it should run on propane even if the circuit board has malfunctioned, it will light but after a few minutes it goes off as well. Any ideas

    Check with a meter what DC voltage you have on terminal block backside of fridge with fridge off and with it on


    And what does it indicate if there is a difference, should they read 12 volts either way?


    Yes.....DC voltage should stay constant.

    It will indicate whether you have good dc voltage to fridge and that your dc voltage from battery/converter is maintaining when fridge turns on.

    If constant then battery/converter is not problem and problem is fridge controls.

    was this something you had added? because the OEM fridge/freezer should be a 2-way, not a 3-way.


    No I was mistaken, I thought because I unplugged the as cord and the lights on the front panel stayed on it was running off the DC

    I think that would be Dometic.


    Love these new fangled devices that change the spelling for you. Dometic.


    So THATS why all these posts say DomeStic instead of Dometic. Spell check changes them. I always thought the OP's were bad readers and spellers:B Doug

    does this mean it will operate on 12v for boon docking?
    Maybe, but it will drain your batteries in short order.

    Loss of 12V DC power (as in low DC voltage) or bad circuit board are the two common components between ALL means of operation..120V AC, propane or DC heater


    If the fridge comes on without the 120v access cord plugged in, does this mean it will operate on 12v for boon docking? How would I go about testing for low voltage coming into the board?
