Lennox 13HPD-060 Flame Sensor
A flame sensor is one of the safety features that will sense the proper flame while the system is starting. Because of the safety issues involved, if the sensor generated a error the system will halt for as long as the problem remains.
Elements of a worsening primary flame sensor
- The unit will work rarely when it thinks it should
- The gas that has entered the furnace refuses to try to begin an ignition sequence and closes down
- Your heating system is unwilling to even begin to start when you want it to
