International Comfort Products GPCM48K120F Thermistor
In an HVAC system, a thermistor is a type of resistor which has a resistance that is contingent on the current temperature. The heating and cooling system needs to know the temperature throughout the whole system to be sure everything is going well. They inform the heating and cooling system when the temperature reaches a certain point.
Subtle hints your all-important thermister will have to be replaced
- The system blower refuses in the attempt to ramp up the airflow
- The heating and cooling system may never start up due to a broken thermistor
