Lennox XP13-042 Ignition Control Board
Another safety feature is the ignition control board, which oversees the natural gas, the ignition timing and all the flame sensing devices. It has always been a vital device that some manufacturers have decided to blend to be a standard part of the main board for safety reasons.

- Ignition cycle declines to activate when called upon
- Any other device within the heating and AC system is researched and comes to be flawless
