For the N841, the current thermistor is the Norcold Thermistor 636658/621742, and it's in stock. Test the old one first. See our quick thermistor test. If the fridge isn't cooling at all, the thermistor is rarely the cause. Check that the boiler area gets hot on AC and propane. If it does and it still won't cool, the cooling unit has likely failed. See our not cooling guide. The N841 is discontinued, and Norcold's replacement is the Norcold N8X. See our Norcold replacement guide.
