Payne PY2PNB060115AA Thermistor
In an HVAC system, a thermistor is a specific kind of resistor whose resistance varies depending on the amount of, or lack thereof, heat. They convey to the heating and cooling system when a certain temperature reaches a certain point. The HVAC system interprets the temperature throughout the whole system to do its job correctly.
What red flags are there that my Payne thermister is in need of replacing?
- The system blower fails in its attempt to engage full speed
- The AC and heat system may not even start because of the stuck thermistor
