Fridge Question

What am I doing wrong? Refrigerator worked fine last use in November.

Dometic gas/AC. Has 3 buttons: on/off, auto/gas, and coldness. Plugged into 50amp shore power, everything else electrical working. Fridge refuses to run on electric. Turn on, idiot light for automatic switchover is lit, after 10-15 seconds always switches to gas.

??
  • Need to make sure that you are getting AC power to your heater probe. You have a control module that is the brain of your system. If your coil were bad you would never get any cooling, so if your cooling on gas then your control card is bad and you can order a new one on line.
  • * check AC circuit breaker
    * open external compartment and be sure fridge is plugged in

    are other 120VAC appliances working....microwave, air conditioning???
  • Switches to 'gas' operation because fridge is NOT seeing 120V AC power

    5A fuse on lower control module in outside compartment.
    If blown no AC for electric heat element. If blown electric heat element is probably bad

    Go outside and open the Fridge's outside compartment.. There will be an outlet there, may be a single or a duplex.. Plug in a test lamp (A trouble lamp will do, or any 120 volt test lamp, table lamp, or simple (non electronic) Device, Or if all you have is a radio. it will do) Does it work? YES, next step, NO you have a 120 volt supply side issue.

    On the bottom is a small circuit/terminal board, this is NOT the control board,, It has fuses, WITH THE FRIDGE UNPLUGGED check those fuses.. ONE of them is, as I recall, a 120 volt fuse (You can follow wires to figure out which, simple board) the others are 12 volt.

    Post results.

    When you replace the outer cover..... REMEMBER the Drip Tube on Dometics goes through a vent hole to the OUTSIDE of the compartment.. One possible issue is water dripping on that simple board may have tosted a trace or connection,, This is easily fixed, but.. Why make it happen?
  • Might be something as simple as a GFI plug. Check all your plugs that have GFI reset. Dont forget in the fridge compartment

  • Tnx all! It was the GFI. DiL fixed it when her tablet would't charge. Geez, I never would've figured it out on my own. Checked all the breakers & fuses, everything seemed to work okay...but most everything is 12VDC. If I didn't know better it would've really surprised me that virtually everything AC in the RV runs on a single 15amp circuit.
