Lennox R22 Thermistor
A very basic thermistor is a special kind of new age resistor that has a fluctuating resistance that is dependent on the heat. The system deciphers the temp in a few critical areas to know what to do next. They tell the heating and cooling system when the temperature has been reached.
Important clues of an inadequate Lennox thermister
- Primary blower could never begin to begin to get up to full speed
- The initial sequence could possibly never start depending on which is the thermistor that is damaged
