Dometic NDR 1062 fridge quit, won't run on AC or propane

Thanks for the replies, Joe. I think you're right, the cooling unit is dead. I left the fridge and freezer doors closed for 3 hours while I had the heater directly wired on, and the temp in the freezer never even rose a degree. When it was working, the fridge and freezer would already be cold by then, and that was in the summer.

I have a decision to make, either get a Frigidaire residential fridge for $400 and change, or replace the cooling unit in this fridge for $655+ shipping.
