Goodman GHS80704BN Ignition Control Board
The main reason to have an ignition control board is that it has control over gas flow, the ignition timing and other safety devices built into the system. The ignition control board was always an important electronic safety board that is now usually a piece of the main circuit board instead of its own individual board.
Major signs your Goodman ignition control board is in dire straights
- Initial ignition sequence is unwilling to start at all
- Every other device throughout the system is inspected and turns out to be flawless
- The initial signal from the home thermostat never does reach the main control board
