Goodman GKS90904CXAC Control Board
The Goodman GKS90904CXAC control board is made to regulate the gas valve, the ignition igniter, all the various sensors as well as the blower all in one unit. The entire heating and cooling system will not activate without the board properly connected to the unit. You must do some research when you are choosing a replacement board due to variances between brands, models and types of systems. The selected board is supposed to have a part number that matches both the make and model of air handler system you have.
How can I tell if my primary control board needs replacing?
- System has flashing code revealed somewhere on the circuit board
- System ceases to operate properly
- The system has to be reset habitually for it to run correctly
