Goodman GKS90704CXAC Control Board
The Goodman GKS90704CXAC control board is made to direct the gas valve, the igniter, the flame sensor and the blower all together. Your furnace or AC will not run at all without the control board configured and seated properly. The board you select should match both the brand and model of furnace or air handler you have. You should always be careful when choosing a control board due to differences in brands, models and types of systems.
Chief elements to watch for in a failing Goodman control board
- Power to the circuit board has to be powered down and back up many times a day for the heating or cooling to kick in
- Entire unit refuses to work whatsoever
- There is flashing code displayed on the control board
