Hello,Depending on the age of the unit, it could have a compressor going bad on it, as the compressor gets hot the valves may not be seating correctly or may be burning out.
You may have also lost some refrigerant, but I am going to lean more to a bad compressor.
Thanks

Freezer gets cold frig is hot. I replaced theromister.did no good


If your Dometic refrigerator is a tri-power model (12V, 120V, lp gas), check all modes. It is not uncommon for these units to fail to cool adequately in 12V mode, as that mode is only for KEEPING things cold while on the road.
If the failure exists only in 120V mode, replace the 120V heating element. If the failure exists only in lp gas mode, replace the burner and make sure that the jet is clean.
If the refrigerator does not get cold in ANY mode, verify that the door seal is making good contact all the way around and, if it is, you'll need to replace the coil assembly. (They are available on eBay and Amazon at a fairly reasonable price.)

Dometic RM2652 was working fine then stopped - no lights at the control panel above the doors.


Usually there is a short in the system when fuse is blown. Check the cord as sometimes mouse can damage the cord. It is a posibility.
Check power to the electronic board.

I have a Dometic RM 2620 fridge, that won't cool. A squirrel got into wiring, I have taken care of wiring but will not work on gas or AC. Spark igniter will no spark either. Any ideas?


Since I don't know what does work I am kind of shooting in the dark.
Does the ac heater get hot ?
The spark ignitor is part of the control board. But won't work?
I assume that you have a user manual but I am including a link to download one.

Note that there are three fuses. B (12V control) and C (120V Heater) on the control board and a thermofuse L located on the stack.
If L is good and everything else is good there should be 12VDC on J1 and at Fuse B

We have a 1993 Wilderness RV with a Dometic refrigerator, brain box being of Dinosaur brand (which is ok - reaching 120 volts) Our question is on the front freezer door of the fridge is a strip plate...


Hi

Most of these mobile refrigerators can run on gas, 120v or 12v, your gas option is obviously OK, there should be electrical connections on the back of the unit which identify which cable are 12v and 120v.

Again most but not all units were multi option.

You will need to connect these points to the supply. To run this on mains 120v you will need to switch off the gas and 12v, similarly for 12v, no gas or 120v, and for gas no12v or 120v.

If you get the fridge to run on 12v remember that if it is on overnight it can reduce the battery charge.

The best options for these is gas or 120v when you have a mains hook up

Hope this helps

My 3-way Dometic fridge works on gas but stopped working on 240V! ....Why?


With the 240V element diconnected, test it with an ohm meter to find it was open circuit. No heat! The 12v element still had resistance.
At the moment gas is still keeping my cool while I wait for a new element to arrive. ..... cheers

Dometic rm2652 frige just stopped working, gas nor


Check 12V supply and fuses on lower board. If display functions okay, then look for yellow residue on back of refrigerator near burner. If yes, then cooling unit has leaked and needs to be replaced. See if recall kit has been installed, and check for 12V at both sides of limit switch. If no power on either side, then thermal link has blown, and need to be replaced, If 12V on one side, but not the other, than limit is tripped, and needs to be reset, by pushing button, or if not resetting, then replace, Check for obstructions to the bottom and top vent to make sure they are not blocked, On models with top side vent, check cooling fan for proper operation.

Dometic RM2193 Works on 120V, but not on gaz. I succeded in cleaning the burner jet and I get a flame. It ligth well now but the flame very small. The frig doesn't cool. Help ?


These fridges require that the control switches be in the correct position for the power source you want to use. If you try to operate the fridge on gas and have the electric 120V-AC switch on, all you'll get is the gas pilot light to stay lit. Also, when running on gas, the electric has to be off.

Here's a link to the manual for your unit. Print a copy and save an electronic one for future use, in case you lose your printout.

Hope having the manual helps you to get the fridge working on all the power sources you need! Best regards!
