International Comfort Products NAC024GKA1 Thermistor
A thermistor is a thermal resistor, which has a resistance that changes as it depends on current temperature. The system needs to know the temperature in a few critical areas to make a decision on what needs to be done. They inform the system control board when the temperature has been reached.
Signs the system thermister will soon need to be replaced
- The initial sequence may not even begin to function depending on which is the stuck thermistor
- Blower fan could refuse to begin to ramp up to full speed
