Lennox G43UF Thermistor
A thermistor is a certain type of resistor that has a varied resistance that is solely dependent on thermal temperature. The furnace or AC interprets the temperature in some specific areas of the system to make a decision on what needs to be done. They inform the HVAC system when the temperature has been reached.
Symptoms of a weak Lennox thermister
- The main fan may fail in the attempt to ramp up
- The heating and AC system may never start up because of the thermistor that is stuck open
