Dometic issue

Temperature was 115 for 3 days and the fridge stopped cooling but the freezer was working ok. Now after the big heat has gone the fridge is working again. Local rv store felt the issue was overheating and is going to see if the cooling unit needs to be replaced. This is something we have never experience before and have been rving since 1996. But never this hot. Dometic 12 ft. 2019 fifth but used one trip. Probably will get it tested . Anybody experienced this issue?

    Freezer cooling but food compartment wasn't

    I would say that was an obstructed cooling unit


    BUT you went on to say that after the big wave passed the fridge starting cooling again (as in the food compartment got cold also?)

    That suggest big lack of AIRFLOW/DRAFT across backside of fridge to remove the heat

    Hot air has a hard time absorbing more heat so heat generated by fridge was not fully being removed in sufficient vloume to have enough cold coolant to absorb heat removed from freezer AND food compartment

    FANS at top to PULL air in/push it out
    Proper clearances across backside of fridge...less then 2"
    Baffles to direct airflow if clearances are to wide


    Test:
    Unplug thermistor and let fridge run for 12 hrs
    Freezer and food compartment get COLD....cooling unit is functioning

    HEAT has to be removed..airflow/Draft
