Lennox CB29M-51 Flame Sensor
A flame sensor is a vital part that will consistently detect the acceptable flame upon ignition. As you could guess, if the flame sensor gets set off the gas valve is shut off and the system halts for as long as the problem remains.
Key signs of a laboring safety flame sensor
- Your gas furnace is unable to ramp up and produces an error code on the circuit board
- The propane or natural gas will not even try to ignite and the board throws an error
- The entire heating system will work intermittently when it wants to

If you are not sure about the installation of the flame sensor on your own then it would be in your best interest to consult a pro to do the replacement of the part.
