Good job finding the bad thermistor. If it still won't cool with no codes, next check whether the boiler area at the back is getting hot on electric and on propane:
1. If it's hot and the fridge still won't cool, the cooling unit is likely failing. Look for yellow residue or an ammonia smell. For the N8, we carry the Norcold Cooling Unit 693299. 2. If it only fails on electric, check the AC heater 638374. 3. Make sure the fridge is level while it's running.
See our not cooling guide and N7/N8/N10 help article. A 2019 fridge may still be under Norcold's cooling unit warranty, so check with your dealer too. Our Tech Support service can help you narrow it down.
