Norcold NX811, NX841, NXA841 Thermistors & Thermostats

The thermistor (or thermostat) tells the control board how cold your Norcold NX811, NX841, NXA841 is so it knows when to cool. A bad sensor is one of the most common reasons an RV fridge freezes everything, runs warm, or ignores the temperature setting.

Most thermistors clip onto the cooling fins inside the fresh-food compartment and plug into the control board, so they are usually a quick do-it-yourself replacement.
