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!

Add-on Fridge Temperature Adjuster for Dometic Fridge
In this video, I install an add-on temp adjuster from Dinosaur Electronics for my Dometic RV fridge. It plugs in series with the fridge’s thermistor, allowing for better cooling control. I read that many people using it were able to get lower temperatures.
I had recently replaced a faulty thermistor and still wasn’t happy with the temps. Even when adjusted via a slider control, the lowest temp on the top shelf was around 36F. With the new adjuster, I’m pleased to report that I can now get the fridge’s top shelf down to 34F or a bit lower and -2F in the freezer. About perfect in my book.
