Dometic Fridge Hard to Regulate when Traveling

As someone else has pointed out, this can be caused by the propane burner element getting clogged both by droppings from the flue and just normal corrosion. I have had to clean our burner several times and replaced it once. When the burner is clean, propane will keep the refrigerator colder than AC.

The burner can be cleaned by you, but it can be a little tricky to get out. The cleaning can also make the slots in the burner too large depending on how you clean it.
