I recently purchased a 26' 1968 AS international Overlander. It is in pretty good condition with all the original equipment. All of the appliances are in fair/good working condition except for the refrigerator. The refrigerator is a Dometric model MB 52. The electric heater and LP gas burner both work, however the unit does not cool at all. How can I determine exactly where the problem is with this unit? I would like to repair this unit if at all possible, as the current cabinetry is built around this model. If I have to replace the refrigerator, some inevitable remodeling will have to be done, which I would like to avoid if at all possible. I recently read that if you turned the refrigerator upside down that may help by moving the ammonia around. So I spent the better half of an afternoon, disassembling the kitchen to get the refrigerator out. I flipped it upside down, and on all sides as recommended, but it still does not cool. You can easily here what I assume is ammonia sloshing around in the coils as you turn it upside down. Is there any hope for this unit? In general appearance it seems to be in good conditions and hardly ever used. It has probably not been used in at least 4 of 5 years...probably more.
