Lennox G40DF-48C-090X Flame Sensor
The flame sensor is only found on gas furnaces. It is a sensor that can sense the precise flame when the system starts. As you would probably could have guessed, when the flame sensor is activated the gas valve is shut off and the system halts until that particular problem is fixed.
Signs your furnace flame sensor is failing
- The unit operates infrequently only after the second full moon of the month on a Tuesday
- Your system is unable to even begin to start whatsoever
- Any type of gas that has entered the furnace will not even try to begin igniting and closes down
