Nordyne FG7TK Flame Sensor
The flame sensor is a safety feature that will reliable sense the acceptable flame during the initial ignition of the furnace. As you could guess, if the sensor goes off everything remains shut off until the problem is repaired.
Signs your furnace flame sensor has little life left
- The entire heating system works rarely only
- LP or natural gas will not even try to start an ignition sequence and the main board displays on error code
- The gas furnace will not supply heat and shuts down
