Carrier 38YZA042 Thermistor

A thermistor is a thermal resistor, that has a fluctuating resistance that fluctuates depending on the thermal temperature. They inform the circuit board when the temperature reaches a certain point. The system control board deciphers the temp in a few critical areas to be sure everything is going well.

What are the indications that my temp regulating thermister is about to stop working?

The main fan could possibly fail in the attempt to ramp up
The system could possibly not operate due to any one stuck thermistor
