Payne PH2PNB024000AA Thermistor
A thermistor is a specific kind of resistor that has a varied resistance that will fluctuate depending on the current temperature. They tell the system when a certain temperature reaches a certain point. The main control board takes the temperature in a few critical areas to be sure everything is going well.
What signals that my system thermister is failing?
- The main fan could fail to begin to ramp up
- The whole HVAC system could possibly not operate due to a improperly set thermistor
