International Comfort Products HHP224AKA1 Thermistor
A very basic thermistor is a certain type of resistor which has a resistance that changes as it depends on temperature. The furnace or AC needs to know the temperature throughout the whole system to be sure everything is going well. They can tell the main board when a certain temperature has been reached.
General indicators that your your all-important thermister will need to be replaced
- No component may not even begin to function due to any one damaged thermistor
- The main blower could possibly fail in its attempt to ramp up to full speed
