Goodman GPH1430H41AB Thermistor
In an HVAC system, a thermistor is a certain type of resistor whose resistance will fluctuate depending on the heat. The main control board interprets the temperature in some specific areas of the system to ensure that things are as they should be. They tell the circuit board when the temperature reaches a certain point.
Major signs of a dying temp regulating thermister
- Main blower could possibly fail in its attempt to engage full speed spinning
- The entire system may never start up due to any one thermistor that has failed
