Question about Dometic RM2452 Refrigerator

Open Question

Hi my Dometic RM2510 fridge does not seem to work on 12 volt at all. I was told that it was a three way fridge when purchased with van - The power selector switch has elec/gas/12volt selection available. Have checked terminal voltage at rear of fridge and is getting full 12 volts. Works great on 240 volts. Can you help? Is there a separate element for 12 volt? Regards Nigel

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.

No you need 12vdc for the control board. If you have a convertor 110ac to 12vdc this will work for your supply instead of the battery.

Cant find the fuse for the refrig. no power


Check connection for 12 volts, at back of fridge behind vent cover .(outside) Make sure 12 volts getting to the lugs where they join. If you have 12 volts to there, unplug fridge at receptacle usually on left side by back of fridge, just to be safe. Remove cover on circuit board and look for a blown (glass type fuse in there.)

Hi Tom,

If your fridge quit working altogether, check your DC fuses in the fuse box, as well as the back of the fridge under the black plastic cover (3 amp). Though the fridge uses LP and 120vac to cool, it is controlled by 12 volts.

I have a dometic rm 689 in my 1970's kustom koach trailer and i'm trying to understand usage. it has a 3 way switch on back of it that i don't know what it's for. can you tell me


Three way fridge:
1: Runs on 12 volts from the trailer batteries. Hard on power and uses batteries frightfully fast.
2: Runs on propane. This is best for places where there is no 120volt power lines. This still needs 12 volts to CONTROL the fridge so have a battery on board.
3: Runs on 120 volts. Great if you can plug in the trailer.

We have a 3 way Dometic fridge in our caravan. Have lived in the van for last 12 months ( grey nomads) have had no probs until trip home this week from Yulara to Victoria. Pulled up at night and freezer...


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.
