SPT WA-1220E Flame Sensor
The flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that senses the correct flame when igniting the system. As with any other safety sensor, if the sensor produces an error everything comes to a halt until the problem is fixed.
Important hints your flame sensor is in dire need of a replacement
- System will operate rarely only after the second full moon of the month on a Tuesday
- Your heating system refuses to work when the control board tells it to
- The gas that has entered the furnace will not even try to begin an ignition sequence and the main board displays on error code
