Samsung AQB24J2WC Flame Sensor
The flame sensor is a safety device that will dependably sense the flame during ignition. As you could guess, if the flame sensor gets set off the system will halt until the problem is repaired.
Key clues of a failing flame sensor
- The unit will sometimes work occasionally barely
- Any type of gas that has entered the furnace will not burn and closes the gas valve
- The furnace is unable to produce heat and spits out an error code on the main board
