International Comfort Products GPFM48K120F Thermistor
A thermistor is a specific kind of resistor which has a resistance that depends on the current temperature. They can tell the circuit board when the temperature reaches a certain point. The heating and cooling system takes the temperature throughout the whole system to make a decision on what needs to be done.
Major clues your thermister needs a replacement ASAP
- Primary blower refuses in the attempt to engage full speed spinning
- The whole HVAC system could possibly not operate because of the malfunctioning thermistor
