International Comfort Products HAC442GKA4 Thermistor
A thermistor is a thermal resistor, whose resistance fluctuates depending on the heat. They can tell the main board when the temperature has been reached. The control board must know the temp in a few critical areas to do its job correctly.
Important signs your thermister has little life left
- The entire system may never begin due to a failed thermistor
- Main blower refuses to begin to ramp up the airflow
