Lennox CB29M-51 Thermistor
A thermistor is a specific kind of resistor whose rated resistance is altered by the amount of, or lack thereof, heat. The heating system must know the temp in a few critical areas to ensure that things are as they should be. They can tell the system when the temperature reaches a certain point.
Main clues the Lennox thermister is in need of replacing
- The heating and AC system may not even start due to any one thermistor that is damaged
- Blower fan could never begin in its attempt to begin full speed blowing
