Samsung AQB09JJWC Flame Sensor
A flame sensor is only used on furnaces that burn gas and is one that can reliably detect the precise flame in accordance with the initial ignition sequence. Because of the safety issues involved, if the sensor generated a error the system will halt until that particular problem is fixed.
Major indications the primary flame sensor will not last the year
- The type of gas you use finds it impossible to properly ignite and the board throws an error
- The heating system will not even begin to start when you crank the thermostat up
- The entire heating system operates sometimes when it feels like it
