International Comfort Products PGF036K080A Thermistor
A thermistor is a certain type of resistor whose rated resistance fluctuates depending on the amount of, or lack thereof, heat. They inform the main board when a temperature has been reached. The system needs to know the temperature in several different areas to make sure everything is running smoothly.
Red flags to watch for in a bad thermister
- The heating and AC system could possibly never start because of any thermistor that is malfunctioning
- Blower fan may fail to begin to engage full speed
