Buying Guide for Thermistor for RV Refrigerator

Understanding the Importance of a Thermistor

When I first started my RV adventures, I learned that a thermistor is a crucial component of my refrigerator. It acts as a temperature sensor, ensuring that my fridge operates efficiently by regulating the cooling system. Without a functioning thermistor, my food could spoil, and I would face unnecessary energy consumption.
