Refridgerator Absorption RV\r\nDometic mo# Rm1350 poor cooling

Refridgerator Absorption RV Dometic mo# Rm1350 with ice maker
Last year I was in a place that was 104 deg . I added an additional fan to the outside compartment for additional ventilation.This solved the problem until recently.
I am now in a place that has not been warmer than 85 all year and fridge has worked fine. however now the temp wont go below 47deg and hovers around 50
a thermomiter that I put into the freezer says 34
I have sped the external fan to high with no change.
refridg just is not cooling as it should. I should mention that I did defrost the fridge as there was ice build up when this first statred occuring thinking this could be the problem . additionaly this entire problem began after we lost power for a few hours. I am fairly sure that there was no surge as there is a surge protector installed.and it did not trip

    do you read the problems?

    this fridge is in an rv and doesent work that way

    it uses heat from either electric heating elements,or gas fire to heat amonia which causes evaporation in the refridgerator to remove heat

    Does not have condenser ,compressor or any moving parts it is in essence electronic

Are your condenser and evaporator coils clean and have unrestricted air movement in the designed path for air to circulate? have you checked for super-heat condition at the evaporator coil? if this is off its possible your low on refrigerant, also a defective temp control ,or sensing bulb if this is a txv type system, also check your pressures with a manifold gauge against mfrs. data

I would check the external componets for dirt a webs and trash that mat have built up .The fan can not cool good with the trash in the way,check and clean the coil also.The defrost timer may not be turning on causing the ice buid uo,thus ,no air transfer where needed.If the defrost timer has quit while the heaters are on,this would also cause the problem.My bet is two things,dirty coil,and defrost is stuck on off and is not melting the ice,if it is stuck and is melting the ice,it could be refreezing the water back into ice also.I hope I am clear?If I can help,any more please let me know.

In side by sides if the fridge side not working correctly it means that the air vent from the freezing unit has stuck in the closed position which causes the fridge to not be any where near as cool as it should be and if it is too cold then the vent is stuck in the open position. The vent is controlled by a small sync motor and either the motor has become faulty, the control module is faulty or the vent is iced up, which can be caused by putting too many hot items in the fridge so the steam condenses and freezes the vent in position and then the motor cannot open or close it causing it and / or the control module to become faulty. Other times it is just old age that causes the motor and / or the control module to fail. Best call a service engineer asap.

In stand alone fridges the answer could be that the cooling panel at the rear is dirty and needs thoroughly dusting / cleaning / unblocking and checking that there is enough space around it to cool properly and that it is not near any heat sources such as an oven, air vent, microwave exhaust, etc.. It could also be caused by a problem that has resulted in a loss of the refrigerant gas and will need regassing by a service engineer. Also check that the thermostat is working correctly, turn it up and the fridge compressor motor should kick in, turn it down and the motor should turn off. Also make sure that the fridge is not iced up, or overloaded, so cool air cannot circulate inside it. Failing allthis it may be a problem with the compressor / motor and will need replacing.

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 refridgerator Rm3762 or Rm3962 one year old in my rv. It stopped cooling and is plugged in to 110. I was having problems on lp and restarted it a couple of times.


If your unit is working ongas,check your electric heater element locaged in the large round tube onthe righ handside when looking from the outside. You can check current draw , should be about 2.5 to 2.75 a/c amps. If electriccheck okand the gas is working, check for ayellow residue around the base of the refrigerator on the outside. Also if you have an amonia odor, this will indicate your cooling unit has leaked out and will have to be replaced. It could also be blocked which would cause loss of cooling. Hope this helps
