Goodman GKS90904CXAB Control Board
It is impossible for your furnace or air handler to even run at all without the main control board hooked up and is correctly configured. The Goodman GKS90904CXAB control board is designed to regulate the gas valve, the ignition igniter, the flame sensor and the blower all in one unit. It is of utmost importance when you decide to replace your control board because of the diversity of systems. A control board that you have chosen will have to be compatible with both the brand and model of furnace or air handler you have.
Key symptoms of a poorly working main circuit board
- The power to the system needs to be reset frequently for it to kick in
- System has an error code lit up on the board
- Your system refuses to initialize well
