Why does fridge control board keep failing?

[mubie]

Hi everyone!
Our 2018 Keystone Sprinter fifth wheel has had 2 refrigerator control board failures in 9 months time. This seems a bit excessive to me. Is there something that could be causing these premature failures? What do we check for? Two different RV repair techs have looked at this issue. They seem to eliminate all other possibilities and then say, "well it must the be control board".....

Any advice is greatly appreciated!

It might help get better answers if you post the make and model of the fridge. Were these replacement boards OEM or aftermarket?

The fridge is a Dometic model#2852lbfx. The first failure was the original board, it was replaced with a Dinosaur board which was supposed to have been better.
