A flame sensor is only used on furnaces that burn gas and is one that will reliable sense the appropriate flame in accordance with the initial ignition sequence. As expected, if the sensor generated a error the furnace will not start until that particular problem is fixed.
Easy warnings your furnace flame sensor will eventually need to be replaced
- The gas that has entered the furnace will not start an ignition sequence no matter what
- System will sort of operate intermittently at midnight, but only after the new moon following the fourth Monday of the month
- The heat system is unable to start operating when you crank the thermostat up
