Goodman ATUF193116 Ignition Control Board
Another safety feature is the ignition control board, which keeps an eye on the main gas intake valve, the ignition timing and some other sensors. It has always been a vital electronic circuit board that is now usually a piece of the main circuit board instead of a separate board.

- Every other device within the furnace is looked at and turns out to be okay
- Initial ignition sequence fails to start even when the thermostat kicks it on
- The electrical signal from the primary thermostat never gets to the main control board
