Payne PG8JAA036045AAJA Flame Sensor
A flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that can reliably detect the appropriate flame when the system starts. As with other safety devices, when the sensor is triggered by an event everything remains shut off until the main issue is remedied.
What are some indications that my safety flame sensor is failing?
- The furnace will work occasionally when it wants to
- Any type of gas that has entered the furnace refuses to try to begin an ignition sequence no matter what
- The gas furnace cannot fire up and shows an error code on the board
