Lennox CBX26UH-024 Thermistor
A thermistor is a thermal resistor, whose resistance is altered by temperature. The heating system interprets the temperature in some specific areas of the system to make a decision on what needs to be done. They notify the HVAC system when a temperature reaches a certain point.
What warnings are present when my Lennox thermister is almost going bad?
- The AC and heat system could possibly never start due to any one thermistor that is stuck open
- Primary blower could fail to begin to get up to full speed
