The 81
Scamp we just got has the Dometic rm211. It was not cooling well the 110v heating coil was NG (open) on propane it did cool some but not nearly enough.We checked on the price of a reconditioned cooling unit
after that shock i found in the links an excellent trouble shooting guide,followed the instructions and cleaned the gas jet etc: within a couple of hours i could see it was doing better so with the thermostat set around 8 i let it run overnight and checked it in the morning with the temp gun
The metal tray that the ice cube tray sits on measured Minus 29*f and the far side of the box about 20*f
I have ordered the new 110v heater unit about US $52oo shipped to Florida.Might have avoided the shipping charge by shopping around here but i was so pleased with the trouble shooting info they gave i really felt they earned the business. Don
