Lennox G26Q4-75 Thermistor
A thermistor is a certain type of resistor whose rated resistance will fluctuate depending on the temperature at its location. They can tell the heating and cooling system when a temperature reaches a certain point. The system must know the temp in several different areas to be sure everything is going well.
Hints the system thermister needs a replacement ASAP
- The heating and AC system could possibly not operate because of any malfunctioning thermistor
- Primary blower may refuse in the attempt to begin full speed blowing
