International Comfort Products HAC242AKA1 Thermistor
In an HVAC system, a thermistor is a specific kind of resistor that has a fluctuating resistance that is governed by the amount of, or lack thereof, heat. The heating system reads the temperature in order to understand what is going on. They convey to the circuit board when a temperature has been reached.
