Lennox G43UF-36C-090 Ignition Control Board
Another safety feature is the ignition control board, which manages the gas valve, the ignition timing and other safety devices built into the system. It has always been a vital circuit board that, over the years, has merged to become a major component of the main board for enhanced safety.

- Every other device attached to the system checked out to be swell
- The initial signal from the primary thermostat never makes contact with the main board
- Initial sequence is unwilling to begin no matter what
