International Comfort Products GPCM36H080F Thermistor
In an HVAC system, a thermistor is a certain type of resistor that has a fluctuating resistance that fluctuates depending on the heat. The system control board reads the temperature in some specific areas of the system to understand what is going on. They tell the HVAC system when a certain temperature reaches a certain point.
Signs the temp-regulating thermister will not live much longer
- The main fan refuses in its attempt to ramp up the airflow
- The whole system could possibly not operate because of the bad thermistor
