Lennox G40DF-36A-070X Thermistor
A thermistor is a type of resistor whose resistance changes as it depends on current temperature. The HVAC system deciphers the temp in certain areas to understand what is going on. They tell the system control board when a temperature has been reached.
Signals of an ineffective Lennox thermister
