Lennox XC21-060 Thermistor
In an HVAC system, a thermistor is a thermal resistor, which has a resistance that is governed by thermal temperature. They inform the system when a certain temperature has been reached. The HVAC system must know the temp in a few critical areas to understand what is going on.
Key signs of a faulty temp regulating thermister
- The system blower could possibly fail in its attempt to ramp up
- No component could possibly never start due to any one improperly set thermistor
