We had nothing but problems with our Dometic refer on our TT. It was a 2010 trailer and within a couple of years we had it serviced several times. The last time it broke, the thermostat (thermistor) broke and it forced the refer to go on rampid full time cold and it finally shut down ruining all of our food. We ended up replacing the thermostat with a rotary type that fixed all temperature issues. IIRC, I got the kit form ebay or something and it was very easy to install. It was basically a tiny adjustable resistor that was calibrated to match the resistance range of the refer. Having lost so much food or having hot beers when we got somewhere...we were very happy to find a residential fridge in our new coach.
