Lennox G24-200 Thermistor
A very basic thermistor is a certain type of resistor whose rated resistance varies depending on the temperature. The furnace or AC needs to know the temperature in order to do its job as it should. They can tell the system when the temperature in increasing or decreasing.
Subtle cues of a faulty temp regulating thermister
- Primary blower may fail to begin to engage full speed
- The whole HVAC system could possibly never start due to a problematic thermistor
