Try putting the fridge on propane and drive around a bit. Climb hills, drive on curvy roads, drive on bumpy roads. Do this for several hours. You could have a situation where the ammonia coolant is locked. Years ago, I had a kerosene fridge that would quit cooling. I laid it on its side for a few hours and that solved the problem. The thing is, the coolant has to be able to drain back down to the "boiler." If it develops a gas lock that prevents this from happening, the fridge will cease to function. This is not a problem with compressor driven refrigeration systems, but can happen with absorption systems (which is what the Dometic is). On the other hand, you could have a problem with the electronics which would require replacement of the control board.
