Dometic RM1350 Refer
I have a Dometic RM1350 Refer in my Alpine 5th wheel and it has been giving me some intermittent problems since last July. The unit cools to the correct temperature when first started and will hold it for days sitting in my driveway. We do run the refer while driving to our destination to keep the unit cold. (I will say that the RV is NOT level front to back sitting in my driveway....it has only been during my research to discover what was happening with the refer that I realized the importance of the RV being level.)
The last three trips the unit will be cold on setup at the campsite but has over a period of time (usually within a day or so) will warm up and show somewhere between 45-50 degrees on the display. (A separate thermometer inside the refrigerator side shows a similar temp.) It has not, up to this point at least, gone above 50 degrees. The RV is completely level on the campsite.
I've had the RV at the dealership twice now and the unit has performed flawlessly for them. We've not had the unit out this season but will be going out over Easter. The dealership has had it doing other service for about 3 weeks and still no issues.
My fear of course is that the cooling unit is bad. That's the most expensive repair option but the dealership is telling me that the thermistor and control board test good and are not likely to work intermittently. They are suggesting, and I fear they are correct, that the cooling unit is only partially blocked but somehow clears itself when turned off.
I was wondering if anyone else had experienced similar issues and what was done to resolve the problem.
Thanks.
