Goodman GDH80904BX Ignition Control Board
The purpose of the ignition control board is that it has control over the gas valve, the ignition ignitor and other safety devices built into the system. It is an important electronic safety board that some companies have moved to be a part of the main control board for safety reasons.
Red flags the ignition board will need replacing
- Every other potential issue in the HVAC system is looked at and turns out to be in good condition
- Signal from remote thermostat never moves to the Goodman control board
- Initial ignition sequence is unwilling to kick in when it receives a proper signal
