International Comfort Products H9MPD100J14A1 Thermistor
In an HVAC system, a thermistor is a specific kind of resistor that has a fluctuating resistance that will fluctuate depending on the temperature at its location. The heating and cooling system must know the temp in some specific areas of the system to make sure everything is running smoothly. They tell the circuit board when a certain temperature reaches a certain point.
Some warnings your thermister will have to be replaced
- The system may not function because of any damaged thermistor
- The main blower could possibly fail to begin to ramp up the airflow
