International Comfort Products C9MPT050F12B1 Thermistor
A very basic thermistor is a type of resistor whose resistance is contingent on the amount of, or lack thereof, heat. They convey to the circuit board when a temperature has been reached. The furnace or AC needs to know the temperature in certain areas to do its job correctly.
What to see if the main thermister is in need of replacing?
- The initial sequence may not initiate the starting sequence because of the failed thermistor
- The main blower fails to begin to ramp up the airflow
