Carrier 52F Thermistor
In an HVAC system, a thermistor is a special kind of new age resistor that has a fluctuating resistance that fluctuates depending on the thermal temperature. They inform the system control board when the temperature has been reached. The heating and cooling system deciphers the temp in order to know what to do next.
Symptoms your all-important thermister is on its last leg
- The main blower refuses in the attempt to ramp up to full speed
- The initial sequence could possibly never start depending on which is the broken thermistor
