Lennox 14ACX-042 Thermistor
A thermistor is a special kind of new age resistor that has a fluctuating resistance that is governed by temperature. They tell the HVAC system when a certain temperature has been reached. The system control board deciphers the temp in some specific areas of the system to make a decision on what needs to be done.
Do you know if your all-important thermister is almost dead?

- No component may not even begin to function because of the thermistor that is damaged
