Goodman GCH90905DX Ignition Control Board
An ignition control board controls the gas valve, the ignition ignitor and other important devices. The ignition control board was always an important electronic safety board that, over the years, has merged to become a piece of the main circuit board for enhanced safety.
Do you know if your chief ignition control board is not working properly?
- Everything else within the heating and AC system is inspected and seems to be in good health
- Heating and cooling system does not launch when it receives a proper signal
- Initial communication from the home thermostat never gets to the control board
