Lennox 13ACX-030 Thermistor
In an HVAC system, a thermistor is a thermal resistor, that has a fluctuating resistance that depends on the temperature. The system control board reads the temperature in order to be sure everything is going well. They inform the system when a temperature reaches a certain point.
Elements to watch for in a failing Lennox thermister
- The initial sequence could possibly not operate due to a stuck thermistor
- The main fan could possibly fail to begin to begin full speed blowing
