International Comfort Products T8MPN100J20B1 Thermistor
In an HVAC system, a thermistor is a thermal resistor, that has a fluctuating resistance that will fluctuate depending on the temperature. They inform the HVAC system when a certain temperature reaches a certain point. The HVAC system deciphers the temp in some specific areas of the system to know what to do next.
Main clues the system thermister is in dire straights
- The main fan could fail to begin to ramp up the airflow
- The heating and cooling system may not even begin to function due to any one failed thermistor
