Lennox G40UH-60C-110X Thermistor
A very basic thermistor is a certain type of resistor which has a resistance that depends on the temperature. They inform the HVAC system when the temperature in increasing or decreasing. The system needs to know the temperature in certain areas to ensure that things are as they should be.
Red flags of an ineffective Lennox thermister
- Blower motor may fail in the attempt to ramp up the airflow
- The whole HVAC system may not operate depending on which is the thermistor that has failed
