In this video, I repair my Dometic DM2652 RV refrigerator. It was having trouble maintaining a cool enough temperature. 40-42F degrees was as cold as it would get in the fridge compartment, and that was on the top shelf, usually the coolest location. Normally, it's between 32-36F there. Luckily it turned out to be a faulty thermistor sensor. Simple and cheap repair!
