On my GE Monorgram refrigerator (side by side) I can't select ice (either crushed or cubed) on the touch panel (on the front of the refrigerator). All other buttons work fine. Strangely, if I lock the control panel and press either ice button, it beeps (meaning the buttons aren't broken), but I simply cannot select ice (the water button stays illuminated). Ice maker is making ice absolutely fine. Thoughts? Thanks.
