International Comfort Products NAC236GKA1 Thermistor
In an HVAC system, a thermistor is a thermal resistor, which has a resistance that will fluctuate depending on the actual temperature is perceives. They inform the circuit board when a certain temperature has been reached. The main control board deciphers the temp throughout the whole system to make sure everything is running smoothly.
Easy warnings your thermister will need to be replaced
- The blower may fail in its attempt to engage full speed
- The system may not even begin to function because of any thermistor that has failed
