Lennox HPXA12-018 Thermistor
In an HVAC system, a thermistor is a specific kind of resistor whose resistance is governed by heat. The system control board deciphers the temp throughout the whole system to make sure everything is running smoothly. They inform the heating and cooling system when a certain temperature reaches a certain point.
Do you know if your all-important thermister is crapping out?
- The heating and cooling system may not initiate the starting sequence because of any malfunctioning thermistor
- Blower motor fails in the attempt to get up to full speed
