International Comfort Products PAPC24GA1 Thermistor
In an HVAC system, a thermistor is a certain type of resistor whose rated resistance is solely dependent on temperature at its location. They tell the circuit board when the temperature in increasing or decreasing. The main control board must know the temp in some specific areas of the system to make sure everything is running smoothly.
Warnings of a laboring thermister
- The system blower fails to begin to begin full speed blowing
- The whole HVAC system may not operate because of any thermistor that is stuck open
