Lennox gas furnaces contain an important safety component known as a flame sensor.
Anything else we should know to help you best.
Remember you are not sanding down an auto body but simply ridding the sensor of any build up it may have.
As long as the component senses the flame it sends a message to the main furnace control board telling it to keep the main burner on and the gas valve open.
Once you have removed the sensor gently rub the metal rod only with soft steel wool or soft scotch brie type pad never use sandpaper as it will damage the flame rod.
