Lennox HPXA12-024 Ignition Control Board
The main ignition control board controls gas intake, the ignition timing and other important devices. It is an important safety feature that is usually a major component of the main board instead of its own individual board.
Subtle cues of an inadequate Lennox ignition control board
- Initial sequence is unwilling to commence when it is supposed to
- Any other device in the HVAC system is inspected and seems to be all right
- Communication from the primary thermostat never gets to the main board
