International Comfort Products PGMD24G0905 Thermistor
A very basic thermistor is a certain type of resistor that has a varied resistance that is altered by the amount of, or lack thereof, heat. They tell the system when the temperature in increasing or decreasing. The main control board needs to know the temperature throughout the whole system to make a decision on what needs to be done.
What are the clues to watch out for to know my system thermister really needs to be replaced?
- Main blower could never begin in the attempt to ramp up the airflow
- No component may not operate because of the thermistor that is the problematic one
