Lennox 13HPD-024 Thermistor
A thermistor is a certain type of resistor whose rated resistance will fluctuate depending on the temperature. They can tell the heating and cooling system when a certain temperature reaches a certain point. The HVAC system needs to know the temperature in order to make sure everything is running smoothly.
What are the signs that the system thermister is about to stop working?
- The initial sequence could possibly never start depending on which is the damaged thermistor
- Primary blower could fail in its attempt to engage full speed
