I replaced the 5amp glass fuse I checked the resistance of the heater element and it is within tolerance. I have not checked the ground

Are you referring to the 120vac. I have 119 at the back of fridge

I have a Dometic 1350 fridge in my trailer. I’ve had the rear power module fail twice on me in the last several months. First time I got an error message indicating failure. This time no error code it just stopped working on AC worked fine on gas. Replaced the glass fuse started working again for a couple of days then stopped working again. Called Dometic they indicated that it was failed power module again bad relay on the board. What would cause this to happen.
