Your refrigerant may have completely separated in the system. Shut of the gas, disconnect the electrical and remove refrigerator from the coach or if you have sufficient room inside set it on a clean area. This operation is what is called burping the system.
1. From the base roll it onto the door and wait five minutes.
2. roll it onto the top and wait five minutes.
3. Roll it on the back and wait five minutes.
4. Return it to the base and wait five minutes.

Reinstall it or test it on electrical. It should show signs of cooling in about 30 minutes in the freezer compartment if the system is not plugged in the boiler.

Temperature does play a big part in the efficiency of the fridge. The condenser at the back of the fridge needs cool air flow to allow gas vapour to be converted back into a liquid.again.

SOURCE: Hi, My dometic RM 2350


More that likely the control board has gone bad or the thermostat quit working. You might have to try and light this on gas several times to finally get it to go, if there is any air in the line it won't light and the air must be purged. This can take several minutes of continious trying to get it to light. When it kicks off switch from gas to off and back to gas again till it lights. Have you checked the thermocouple that lets the control board know that there is fire in the pilot? If this is bad it won;t kick the main gas valve on. You can check these with a volt ohm meter, when there is fire on the thermocoule you will get a small voltage reading in the mil amps portion on the tester, no reading means bad thermocouple.

When you say failed, what all happened, are the lights on the fridge indicating electric or gas working? Is it just not cooling? Have you hecked for power to the control board on the fridge? There should be a wire diagram on the cover for the board on the back of the fridge, check to see if you have power coming in to the unit, if not check your fuses.

Three year old Dometic RM 2555, 3 way Frig/freezer has failed on 240VAC however works on Gas. I suspect the PCB is faulty


Hello,
My rm2555 has just failed on 240 volt. But not 12 volt.
It turned out to be the 240 volt element .
Fairly easy to replace. If you have a multimeter test the resistance, mine was open circuit.
Does yours work on 12volt?
The two heater elements (ie 12v and 240v ) are on the right when viewed from behind with four large wires coming out, plus an earth wire. There are labels on some of the wires. The 12 volt conects into a terminal connector, where as the 240 volt is fitted with spade connectors and is attached to the printed circuit board, under the white plastic cover. The elements are "L" shaped and are just pushed down in down next to each other. The cover seems to unclip fairly easily to enable removal.
Hope this helps.
Mark

Dometic RM7291L not effectively cooling on 240V but fine on gas


On the back of the unit, at the bottom, there should be a panel that is removable. Inside should be a fan, the condenser coil, and the compressor. The fan has to be constantly blowing air over the condenser coil, to dissipate the heat (which it is essentially being removed from the refrigerator by the compressor)

When the entire fridge stops cooling, one of three things have happened. The fan isn't removing the heat from the coil, or the compressor isn't compressing the freon, or the freon has somehow leaked out of the system. If it is the fan, you have an easy do it yourself repair. If it is the compressor or the freon, you will probably (but not necessarily) need a professional.

Inside the fridge, there is a coil that is cold instead of hot. A fan must continually blow over that one too, to circulate the air over the cold coils. The fan usually only works when the doors are closed, so be sure to have the door switch pressed to "shut" when checking it.

Check those and post back. And, I know... it really is Dometic.
