Dometic RM2192 Problem, Works on AC, not Propane.
Greetings,
Update to my post last month. Bought this RM2192 back in 1984. It is the type with the stainless steel exhaust and intake tubes instead of the rectangular vent. Have used it alot during the 31 years and it has worked great. Repairs here and there but nothing major. Right now it works great on AC but is not cooling properly on propane. Did all my normal things like cleaning the burner box, exhaust tube, jet, turning it upside down for a day or two to dissolve any ammonia crystals that my have built up in the tubes. Still does not cool. With the volume at max I checked the pressure at the access point just downstream for the thermocouple and it was 12" of water. Pressure out of the jet was also 12". Fired it up and with volume at max it only had a small flame. Lowered the volume to minimum and the flame did not change. I usually can hear the thermostat click on and off when I spin the dial but can no longer hear it click. From experience I know the difference of High and Low flame and both flames are low. If this model was still on the market I would buy a new one or if parts were still available (new or used) I would buy them. I use the refrigerator for exploring back roads, especially in the desert, in my 1984 van and if I bought a different refrigerator model I would have to make drastic changes to my counters and punch a large hole thru my van wall. If it is the thermometer is there some way to possible fix it or at least set it so it is always on max. When I'm exploring in the warmer months it is usually on max 24 hrs a day anyway. Any advice or tips would be appreciated.
