Signs the cooling unit has failed:
- Yellow powder or residue around the back of the unit, or an ammonia smell - The heat source works (flame on gas, heater warm on electric), but after a few hours the condenser fins at the top back stay cool - A gurgling sound with no cooling
If that's what you see, the 636411 was the unit for the N300 series, but it's discontinued. The Norcold N4150 is the current replacement fridge.
