DO NOT run refrigerator when it is in your driveway on a hill. I ran it all night the night before we left and it ruined the cooling unit.

That's to bad. I don't know what your plan is but before you replace the cooling unit check that Amish fix.

If it is not covered on warranty, I would suggest talking to the people at rvcoolingunit.com. The phone number is 901-337-9948. I have found them helpful in the past

I think the evaporator has failed however if you believe that running the unit while off level caused the problem there is an old cure. In the old days sometimes a air bubble would form in the evaporator. to remove it we would take the frig out, turn it on its side for a while, then reinstall. Been a long time since I have done this or heard of it being done. As I say it is an old time fix.

Phil have yiy ever heard or seen this? You have been around as long as me.

I run the LP/electric refrigerator in my 2009 Berk all the time, underway, stopped, on hills. What is it that makes this a bad idea?

Running the rerig underway and while stopped is not a problem. Running it on a hill when you are not level is what causes problems. The refrigerator keeps cold by heating the tank in the back of the refrigerator that has liquid ammonia in it and the when heated forms ammonia gas. When the ammonia in gas form goes through the tubing in the back of the refrigerator and cools, the cooling gas absorbs the heat from the refrigerator box. If it is not level, the flame or electric heater may heat the ammonia tank while the ammonia liquid is not near the heating element causing the ammonia to crystallize and clog the tubing in the refrigerator. Once the tubing clogs, the unit will not function.

This is my understanding of how the absorption refrigerator works. If anyone else has a better understanding or explanation, I hope they post it.

Here are photos of my replacement whirlpool French door of the erratic dometic refrig. It was a snug fit. My model has the fan heater below refrig. I did little mods as opened top up to fit. My motorhome mechanic removed the old and brought in and set the new. They had to come through my big window over couch as needed about 3 people to lift it. The pros are cold consistent refrig for past 2 years. The cons is it won't unless plugged in 30-50 amp or on generator which traveling in Texas heat I run regularly and keep it plugged most always.
