The flame sensor is an important safety feature that can reliably detect the flame upon ignition. As expected, if the sensor goes off the system will halt for as long as the problem remains.
Major signs of a weakening safety flame sensor
- Your gas furnace is unwilling to produce heat when the thermostat kicks in
- The gas supplying the furnace refuses to try to start an ignition sequence under any circumstance
- HVAC system will sort of operate on certain occasions at the stroke of midnight after the second full moon following the second Sunday of the month
