International Comfort Products CAC430GKA1 Thermistor
A very basic thermistor is a specific kind of resistor that has a fluctuating resistance that is contingent on the temperature at its location. The HVAC system interprets the temperature in certain areas to understand what is going on. They tell the main board when the temperature in increasing or decreasing.
