Lennox CB27UH-042 Ignition Control Board
Another safety feature is the ignition control board, which controls the main gas intake valve, the ignition sequence and a few other devices. The ignition control board was always an important board that is usually a vital part of the main control board instead of its own individual board.
Major warnings the ignition board is going to die
- Ignition sequence is unable to begin when it receives a proper signal
- Initial communication from the home thermostat never gets to the main board
- Any other potential problem within the furnace is researched and comes to be just fine
