Some clues of a failing flame sensor
- The whole system starts occasionally at the stroke of midnight after the second full moon following the second Sunday of the month
- The gas furnace is unwilling to work when you crank the thermostat up
- The gas entering the furnace has problems trying to properly ignite and closes down
