Lennox G61MPV-60D-135 Thermistor
A thermistor is a specific kind of resistor that has a fluctuating resistance that is dependent on the temperature. They inform the HVAC system when a certain temperature reaches a certain point. The control board reads the temperature in some specific areas of the system to do its job correctly.
Clues of a dying Lennox thermister
- The main blower may refuse in the attempt to ramp up the airflow
- The AC and heat system may not initiate the starting sequence due to a improperly set thermistor
