Lennox CBX27UH-060 Thermistor
In an HVAC system, a thermistor is a special kind of new age resistor that has a swinging resistance changes as it depends on current temperature. They tell the HVAC system when a certain temperature has been reached. The main control board takes the temperature in a few critical areas to do its job as it should.
Indications the Lennox thermister will die soon
- The main blower could fail in the attempt to engage full speed spinning
- The whole HVAC system could possibly never start because of the thermistor that has failed
