Lennox HPXB15-048 Flame Sensor
The flame sensor is only found on gas furnaces. It is a sensor that can reliably detect the proper flame during ignition. As expected, if the flame sensor senses a problem the entire HVAC system will stop until the problem is remedied and the system is reset.
Major indications the primary flame sensor will have to be replaced
- The main type of gas has difficulty trying to ignite and the main board displays on error code
- System will run infrequently barely
- Your heating system is unable to work whatsoever
