Lennox XC16-024 Thermistor
A thermistor is a specific kind of resistor whose resistance fluctuates depending on the thermal temperature. The system deciphers the temp in several different areas to make a decision on what needs to be done. They notify the HVAC system when a certain temperature reaches a certain point.
Important signs the system thermister is on its last leg
- The heating and AC system could possibly not even begin due to a thermistor that is malfunctioning
- Primary blower could possibly fail in its attempt to begin full speed blowing
