I bought a used pop-up last year and was told that the refrigerator worked. Too trusting. Had it working on propane and barely working on 12v. After taking the camper out last year in the mountains of Colorado on some rough roads I can't get it to work. Dometic RM2201. Repair or replacement ideas appreciated.
My old pop up would occasionaly pack in the dirt there. Blow it out or wash and dry ( not a big problem here in AZ ). Try it on AC ( after it drys) and when level before declaring it dead.
Not sure if you have a pilot or electronic in that model -- either way - does it light up when you turn it on? Is it heating the tubes around the burner area? If it is hot but you have no cooling, that tends to indicate a more major problem. If no heating, then possibly a bad circuit board. I would double check you have 12 volts going to the board -- you have to have 12 volts regardless of how you choose to cool. Google your model and see if you can locate the service manual -- there are usually some good troubleshooting steps in there.
