International Comfort Products GNL100N16C3 Thermistor
In an HVAC system, a thermistor is a special kind of new age resistor that has a fluctuating resistance that is directly proportioned to the amount of, or lack thereof, heat. The control board must know the temp throughout the whole system to make sure everything is running smoothly. They tell the system control board when a certain temperature reaches a certain point.
General warnings of a dying all-important thermister
- The blower refuses in its attempt to ramp up to full speed
- The entire system may not even start because of the malfunctioning thermistor
