Goodman GPH1336M43AA Ignition Control Board
An ignition control board controls gas flow, the ignition ignitor as well as other safety devices. It has always been a vital safety device that some manufacturers have decided to blend to be a part of the main control board instead of its own individual board.
Clues to watch for to know your Goodman ignition control board has little life left
- Initial ignition sequence is unable to start when called upon
- Every other device within the furnace checks out fine
- Signal from main thermostat does not show up at the control board
