Hi and welcome to FixYa,

To my understanding most 3 way fridge are manufactured by the same firm in China and marketed under different brand names. The design and electrical system are nearly identical. There would be a resettable circuit breaker and 2 fuses. Additionally they should operate on either gas, 12V or 240VAC but not on two system simultaneously. Of the 3 sources of energy, the 12VDC is the least efficient. At most this could only maintain the cold but not cool food items down, meaning the food items has to be cooled initially before placed in the fridge if the 12VDC is to be used continuously. The gas or 240 is more efficient. Since these designs do not use a compressor, there would be no mechanical/audible indicator that the electrical system really works. Additionally, there are no thermostats to control the temperature. Below is a typical wiring of some 3 way fridge.

I believe that it is best to run your acessories off of your 2nd battery with a seperate fuse box. When they say to run the fridge directly off the battery they mean not to take it through the normal wiring loom. I do not know what size wire they run to the rear plug but, being cynical, I would not expect it to be over large. Run a nice heavy cable, at least 6mm, to the rear and get a better plug/socket combination to replace the cigarette lighter type that is usually factory fitted. If you are not too okay with the electrical side get your auto elec involved. P.S. The better plug/sockets are readily available at caravan supply places.

Test the power outlet with another device, a lamp for example and see if the power is coming there.

Next check the wiring in the refigerator, the 12v side should definitely have a fuse.

How can i tell if its running on 12v or 240v


Running on AC always cools down faster. If you plug it in to AC and the fridge cools quickly then the switch position is AC. Turn on a 12 volt light. Watch the lite while you operate the switch. When the light dims a little the switch position is in the DC mode.

Does the 2652 constantly burn LPG when in gas mode. For some reason (probably told so erroneously?) I was under the impression that the fridge automatically switches off and on the LPG flow/ignited as it...


The RM2652 should shut down when the fridge reaches proper temperature. So yes the flame should go out when operating on propane. If the refrigerator does not get cold enough, then the flame will not ever shut down. It is posible that you may require a replacement cooling unit. WEB SITE: ArctiCold Refrigeration We keep it cold

Fridge/freezer in a motorhome has stopped working on gas any help & advice would be greatly appreciated.


I am guessing this is a "three way fridge" 12 volt, 240 volt and lpg gas.

This is an absorbtion refrigerator and it uses heat to drive the cycle.
The things to do are;
Clean the gas jet, Piezio starter and thermocouple.
Also clean the rust, carbon and scale away from the heater tube and chimney.
Hopefully all will be good again

Electrolux 3 way fridge will not work on 12v or 240,switch lights up, ok on gas. can i repaire?or have i got to replace? i think the model No is rm4200 or rm4230


Hi My three way fridge has the same problem. Have solved the 12v problem as it was not wired to the 12v invertor. Do you have an on board battery supply? the 12v is usless and runs a battery flat in no time. Better off to use gas. Hope to have the electrician here next week to check 240v so will let you know if we find a problem. Graham.

My fredge rm 2652 not working


You need to check your fuses on the fuse panel inside your coach. The frig will not operate on gas or electric without 12 volt power to the frig circuit board.

Between 1993-1996 dometic used a yellow epoxy filled circuit board that went bad pretty quickly if you have the yellow filled circuit board rather than the green one it is most likely the circuit board
