Lennox HPXA12-030 Flame Sensor
A flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that will consistently detect the correct flame in accordance with the initial ignition sequence. For obvious reasons, when the sensor is triggered by an event everything stops until the problem is remedied and the system is reset.
Hints the Lennox flame sensor will need to be replaced
- The heating system works occasionally only
- The gas supplying the furnace will not even try to begin igniting and the board throws an error
- Your gas furnace refuses to produce heat when the control board tells it to
