Dometic 2652 - Fridge Too Cold...System Board?

[DES-1]

We're getting fridge temps down below freezing, into the high 20's!!


I've completely checked the thermistor and using an abundance of caution, replaced it with another working one. Was tested with the factory resistance test procedure. Also, Thermistor position does not change temp.


So I think we are down to a faulty system board. Any disagreement? Has anyone replaced the system board to remedy, and were you successful? Anyone use the aftermarket Dinosaur replace board?



Thank you - Dave

The board was the issue. Replaced with Dinosaur Electronics 3850712.01 replacement board. The fridge is now cycling between a high and low temp and is no longer freezing. It's been running on shore power for about a day. Next step will be to add some warm items and make sure it cools and keeps within the temp range. I'll probably try it on propane as well since all the logic for propane operation is on the board and was therefore replaced.
