Payne PH3ZNA042000AA Thermistor
A very basic thermistor is a thermal resistor, which has a resistance that will fluctuate depending on the temperature at its location. They notify the heating and cooling system when a temperature reaches a certain point. The system control board interprets the temperature in some specific areas of the system to understand what is going on.
Indications of an unhealthy thermister
- No component could never start up because of any broken thermistor
- The blower could refuse in its attempt to ramp up to full speed

If you decide on picking up or purchasing, do your due diligence and cross-check the model number as well as make a visual inspection in order to be sure the correct replacement thermistor is being ordered. You do not need to replace the part all by yourself. Search for a pro locally to hire and install the part for you.
