Goodman GHS80905CXCA Ignition Control Board
An ignition control board governs gas flow, the ignition ignitor and the flame sensing circuits. It has always been a vital electronic safety board that has now become a vital part of the main control board instead of having two separate boards.
Chief elements of a weak major ignition board
- Every other problem attached to the system checks out in good health
- HVAC ignition system fails to activate when it is supposed to
- Initial communication from the remote thermostat never moves to the main board
