Goodman GMS80904BN Ignition Control Board
Another safety feature is the ignition control board, which controls the gas valve, the ignition ignitor and the flame sensing circuits. It is an important device that some companies have moved to be a standard part of the main board instead of a separate board.
Some warnings of a faulty main ignition board
- Every other device within the heating and AC system is inspected and seems to be all right
- The on-signal from the main thermostat never makes it to the main control board
- Initial sequence can not initiate when it receives a proper signal
