SECTION C. MAINTENANCE AND SERVICE

1. PERIODIC MAINTENANCE

To keep your Dometic refrigerator operating efficiently
and safely, period inspection and cleaning of several
components is recommended once or twice a year.
A. It is important to keep the area at the back of the
refrigerator clear. Check the lower vent, upper vent
and the area between these openings for any
obstructions such as bird/insect nests, spider webs,
etc. It is important to keep the refrigerator area free
from combustible material, gasoline and other
flammable liquids or vapors.
B. Check all connections in the LP gas system (at the
back of the refrigerator) for gas leaks. The LP gas
supply must be turned on. Apply a non-corrosive
bubble solution to all LP gas connections.
WARNING
DO NOT USE A FLAME TO CHECK
FOR GAS LEAKS.
C. Check burner flame for proper appearance. The
flame should be light blue with no yellow at the tip.
(See FIG. 16).
