Lennox CBX26UH-024 Ignition Control Board
Another safety feature is the ignition control board, which governs the gas valve, the ignition timing and all the flame sensing devices. It has always been a vital electronic circuit board that, over the years, has merged to become a part of the main control board instead of its own individual board.
How do you know when your Lennox ignition control board has to be replaced?
- The main ignition cycle can not commence even when called upon
- Communication from the primary thermostat does not turn up at the Lennox control board
- Everything else in the HVAC system checked out to be problem-free
