Help, I have a Norcold fridge in my camper trailer. It seems to work great for the first couple of days and then it dips below freezing and there is no getting it back. Even though I bump the thermos...
Sounds like you need a new thermistor ( like a thermostat) and that your frig is going into backup cooling mode which means it just runs every so often as there is no temp indication to tell it when to run. It's a cheap part and sure worth a try.
