Answer Tony, Remove power to the refrigerator, remove anything from the top shelf of the refrigerator shelf and under the control panel box. You may want to remove the interior light cover/lens if you feel it necessary. On the back side of the control box, and along the top where the box meets the ceiling you'll see two slots, one on each side, use a flat blade screwdriver, insert it into the slot and press in on the hidden tab, and pull down on the corner of the box, repeat the same process on the other side. Drop the assembly down enough to disconnect the wire harness from the control board. Carefully unsnap the control board from the mounting tabs inside the housing and remove the board.
