Goodman GMH80903BN Ignition Control Board
The purpose of the ignition control board is that it oversees the main gas intake valve, the ignition ignitor and other safety devices built into the system. The ignition control board was always an important safety device that some companies have moved to be a part of the main control board instead of a separate board.

- The initial signal from the home thermostat gets lost before it makes it to the control board
- Ignition cycle is unwilling to start even though it is supposed to
- Any other potential problem within the furnace is inspected and seems to be all right
