Covering frig vent

Our 8 cu ft Dometic propane/120VAC frig has a lower vent on the back of the trailer and a roof vent. We will be running the frig on 120VAC when traveling this summer, but as I understand it, that's still heater based and the coils still require ventilation for proper cooling.

We're going to be traveling 100's of kms on dusty roads. Initially I was thinking to cover the lower back frig vent to keep the dust out. But maybe not ...

Any suggestions?

The frig has to be working while we travel, and I'm not switching to a household frig at this point .

    YEP.......what he said^^^^^

    Airflow/draft is required to remove the heat from absorber tubes and condenser fins REGARDLESS of which heat source is being used to boil the ammonia

    If you want the fridge to cool,,,,,do NOT block ANY vents while fridge is ON

    Do not cover, fridge will not work right and you could damage it

    If things get so dusty that fridge operation is affected

    Turn off fridge and use comprised air to blow out the dust
    Then turn it back on
