how do I get a operating and trouble shooting manual for a dometic royale rv refrigerator?


Contact the manufacturer, Absorption refrigeration is an infrequently used alternative to compression refrigeration. Absorption refrigerators use a solution of ammonia and water as refrigerant fluid. A gas flame heats the ammonia and provides the energy that drives the cooling process. These models are generally very simple and have few moving parts. This is a very straightforward process. There are three main principles behind proper operation of an absorption refrigerator. Place the refrigerator on a level surface. Make sure that it is adequately ventilated. Check that the correct heat is being applied in the boiler. As long as there are no leaks, this should be enough for the refrigerator to work properly.

I have a Dometic RM3801 rv fridge that was working fine on 120v and then stopped cooling. All the lights come on but the compressor won't run. It is level and the cooling fins are clean. I checked power at the plug outlet it runs a blow dryer.I am unable to try it on gas at this time. Help!


your refrigerator is an ammonia absorption system it does not have a compressor only a series of closed pipes and small tanks located behind the styrofoam box so; to operate yout refrigerator you need: a propane flame or, a 12 volt heating coil or an AC transformer to heat the system depending on if you have a 1,2,or, 3 way system.
also; these refrigerators will only work if you are on level ground
so check your fuses, transformer and, or, your gas thermocouple:
the thermocouple is a rod that sits in the burner flame to control the gas valve if you see some yellow dust around the back of the refrigerator you have a leak of the sealed system don't buy a new refrigerator just replace the system and, be sure that you remove the twisted metal riser in the top of the refrigerator vent pipe to use in your new system or, nothing will work the ammonia absorption sealed systems can be bought on ebay etc.

Fridge works on gas...but not on AC


Your heater should measure 44 ohms, give or take 10%.

95 Ohms is way off. The RM2310 uses a 92 ohm heating element, perhaps you installed / were sold the wrong heating element?

my dometic rm 2612 stops working at least once a day the check light goes on.


Your 'frige has either; a 12 volt power supply or, a gas flame to circulate the refrigerant gas to cause absorption refrigeration to work; check or, replace your power supply as it 1. holds open the gas valve relay, 2. heats the gas with a heating element.
