Carrier 50GS Thermistor
In an HVAC system, a thermistor is a special kind of new age resistor that has a varied resistance that depends on the heat. They can tell the main board when a temperature reaches a certain point. The furnace or AC deciphers the temp throughout the whole system to understand what is going on.
What are some hints that my Carrier thermister is dying?
- The entire system could possibly never start due to any one thermistor that is malfunctioning
- Primary blower could refuse in the attempt to engage full speed
