Lennox 13HPD-024 Flame Sensor
The flame sensor is a device that can reliably detect the flame while the system is starting. As with most safety features, if the flame sensor senses a problem everything stops for as long as the problem remains.
Some clues of a poorly working primary flame sensor
- The gas refuses to properly ignite and shuts off
- System will operate infrequently when it thinks it should
- Your heating system cannot generate heat whatsoever
