The ice maker control says "lock"

Hi, my name’s Doug and maybe I can help you. Have you tried pressing and holding the energy saver button on the touch panel for approximately three seconds. This should unlock the control. If it doesn’t, try holding it longer, maybe 7 to 10 seconds. Hope this helps. Also you can unplug the refrigerator for several minutes and then plug it back in. It might reset the control. If that doesn’t do it you probably need a new control board.
