Refrigerator problem ...fix
Had a nice chat with Dometic tech service this AM..Here is the story. To test the thermistor place it in a Glass of COLD, almost ice water for 15 Mins. The Resistance should read 8 to 10K. That indicates it is good. The problem is almost always the thermistor. For temp control.... The slider that the thermistor rests in is a HOLDER only. Make sure the thermistor is firmly in the slot and moves with the slider.. The slider at the TOP of the fin will cause a DROP in temp (make the fridge colder) that makes sense as warm air rises and warm air sensed at the top of the fin will cause a drop in temp. Camper world carries the thermistor and it cost 13.04 before discount. It is not a bad idea to carry a spare as it is a easy fix. Ours lasted 41 months of nearly constant use. We are now stablized at 40/42 degrees.
Note ..if he thermisor fails..it will get very cold in the fridge... That is the way it is....
