Lennox CBX32MV-018 Thermistor
A very basic thermistor is a thermal resistor, that has a fluctuating resistance that changes as it depends on the amount of, or lack thereof, heat. The heating system deciphers the temp in several different areas to ensure that things are as they should be. They notify the heating and cooling system when a certain temperature has been reached.
Main clues your all-important thermister is failing
- The main blower could refuse to begin to engage full speed
- The whole HVAC system may never start up due to a improperly set thermistor
