Locate the control board panel on the back-right corner of the appliance. Remove the housing screws and slide the access panel off. Unplug the wires to the control board and remove the mounting screws. Repeat these steps in reverse to install the new control board.This control board is a genuine OEM product sourced directly from the manufacturer.
