Dometic 2652 Refridgerator

I have a Dometic 2652. I turn it on and within hours my freezer is 10 degrees and refrigerator is 34 degrees.

The next morning temperatures in freezer and fridge have risen to unacceptable levels (45 and 60).

I unplug the 110 wait a few minutes and plug it back in and it repeats cooling down and heating back up overnight.

It does the same thing using 110 or gas.


Anyone had a problem like this? What fixed it?

    Is rv (fridge) level? Needs to be level for proper cooling.....off level causes permanent damage!

    Have you check for any obstructions in outside compartment------cooling air flow must be free/clear from lower vent up/across backside of fridge to upper vent?
    Have to have good draft!

    Third.....thermistor
    Is it still attached to far right fin in food section?
    Thermistor controls 'auto thermostat'-----bad thermistor/bad cooling
    Thermistor can be tested by unplugging from lower board, placing tip in glass of ice/water (more ice than water) and then checking resistance at leads.......8000/10000 ohms

    Snip-The-Tip Repair Kit for thermistor.....LINK

    And then there is the fact that cooling unit could be plugging, has blockage.
    Unplug thermistor from lower board
    Turn fridge ON (AC)
    Check temps after 12 hrs
    Then check again after 24 hrs
    Then again after 48 hrs
    With thermistor unplugged fridge will run continuously and food section should freeze. IF temps fluctuate then cooling unit is bad.
