Without maintenance, Dometic RV refrigerators will not last as long as they should and will break down often. Dometic refrigerators are a popular model in RVs, and can run off of gas or electricity if the gas doesn't work. There are a few ways you can troubleshoot the gas ignition on a Dometic refrigerator.
Items you will need
Clean the burner tube with a brush if the burner is clogged. Blow out the burner with compressed air. Clean the burner area of all soot and scale.
Properly install the flue baffle tube if it is not in as it should fit. Sometimes it can pop out during travel.
Blow out the burner with condensed air if it is just dirty. A dirty burner can prevent the gas from reaching the ignition.
Set the main regulator so the pressure doesn't drop below 11 inches of the water column at the pressure test port. This should be done is the gas pressure is low at the burner.
Relocate the burner if it is not sitting under the flue properly.
Replace the burner with a new one if the burner is cracked or damaged.
