• Contact a Dometic dealer or Service Center for repair.
• Do not use the refrigerator until it has been repaired.
• Check the thermostat and adjust if necessary.
• Is there a power failure?
• Is the refrigerator level? (Due to the nature of its operation, it is important to keep an
absorption refrigerator level.)
• Door closing properly? Check the door gasket.
• Heavy frost build-up on evaporator fins? To prevent frost buildup, do not leave the unit's
door open longer than necessary.
• Overpacked refrigerator? The unit will have to work harder if refrigerator is stuffed, and re-
sults in higher cabinet temperatures. Arrange food in the unit to allow for free air circulation.
• Is the plug firmly connected to the receptacle? Is the receptacle energized? Check the
receptacle by plugging in another appliance.
• Is there a power failure?
• Blown fuse. Turn refrigerator off and contact a Dometic dealer or Service Center for repair.

for repair.
• Dislocated or damaged burner. Turn refrigerator off and contact a Dometic dealer or Service
Center for repair.
• Dirty flue tube. Turn refrigerator off and contact a Dometic dealer or Service Center for repair.
• LP gas ignition failed. The refrigerator went through a complete ignition sequence, and the
burner did not light. Turn refrigerator OFF and then back ON to return to normal operation.
• Air in the gas line? After changing a gas bottle or after a long shutoff period, the gas line is
likely to be filled with air. You may have to repeat the lighting procedure (45 seconds) by
turning the refrigerator off and on several times in order to purge the air out of the gas lines.
• LP gas bottle is empty and needs replacing.
• Obstruction in or on the burner or burner jet, or burner jet is clogged and should be cleaned.
