check/remedial action
• Immediately turn the refrigerator off and contact a Dometic dealer or Service Center.
NOTE! Do not leave it running for days and never try to solve the problem by repeatedly
restarting the refrigerator.
• Do not use the refrigerator until it has been repaired.
• Immediately turn the refrigerator off.
• open windows and door to air out the coach and evacuate.
• Contact a Dometic dealer or Service Center.
• Do not use the refrigerator until it has been repaired.
• Defective fuse? Fit a new fuse.
• Connection to supply voltage? Establish power connection.
• Is the plug firmly connected to the socket? Is the socket switched on? Check the socket by plug-
ging in another appliance.
• Is the thermostat properly set?
• Is the refrigerator level? Because of its operation it is important to keep an
absorption refrigerator level.
• has the overheating protection been triggered or not? (must be checked by an authorized service
technician.)
• Is there a power failure? Are the fuses intact for the AC supply and control system?
• has the door been closed properly? If not it can cause the inside temperature to rise. Don't open
the doors too often or leave it open for too long - this lets cold air from inside escape and warm
moist air get in.
• overpacked refrigerator? The unit will have to work harder if the refrigerator is stuffed and re-
sults in higher cabinet temperatures. Arrange the food in the unit to allow for free air circulation.
• Venting problem? Restriction in air flow across cooling unit? Ensure that there is sufficient clear-
ance between the refrigerator and the surrounding walls to allow for proper air circulation around
the unit.

• Is the burner dirty, damaged or not properly located under the flue tube?
• Is the burner jet clogged?
• Is the flue baffle inserted properly in the flue tube?
• Is the lP gas pressure low at burner? Set the main regulator to regulate the pressure so it does not
drop below 11 inches water column at pressure tap.
• Gas bottle empty? Change the gas bottle
• Air in the gas pipe? Remove the air by switching the refrigerator on and off 3-4 times.
• have the doors been closed properly? Are the doors well sealed? If the doors are not closed
properly or the seal is poor, cold air will leak out, and warm moist air seep into the refrigerator
causing frost build-up.
• If frost still remains after having performed manual defrosting as well, check the
following possible causes:
has the defrost timer been set properly?
-
has the ice-maker been used during transit? This may cause spillage of water.
-
If dry camping, the battery might not be fully charge. This may lead to poor defrosting.
-
• Dislocated burner
• Damaged burner
• Dirty flue tube
