International Comfort Products GDL100N16A1 Thermistor
In an HVAC system, a thermistor is a specific kind of resistor whose rated resistance is dependent on the amount of, or lack thereof, heat. The HVAC system deciphers the temp in a few critical areas to know what to do next. They convey to the system control board when the temperature has been reached.
What are some indications that my all-important thermister needs replacing?
- The system could possibly not operate because of any thermistor that has failed
- The main blower fails to begin to get up to full speed
