I've worked on and replaced a few of the norcolds.? I think that the thermocouple is relatively universal and can be found on a variety of RV sites. You just want a length that is similar to the stock one.? That said, I don't think the thermocouple usually fails.? in my experience its mostly the relighter board that goes out.? These fridges seem to eat them a little too often.? you can find them online on a variety of sites for a bit over $100.? I've gotten to where I can replace one by just removing the panel above the fridge and not having to pull the whole unit.
