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.
