Maybe remove the control pad and clean the contacts (carbon contact perhaps) or verify with a volt/ohm meter that the contacts are still working or jumper the wires that lead from the contacts to see if it dispenses.
When I press on the pad with a glass I do hear a click and the small door opening where the ice comes out. Just the dispensing motor won't turn most of the time. Sounds like your on to something. I'm not sure how to remove the the Dispensing unit. Can't find a video that looks exactly like mine. It does have a tray at the bottom that slides out with two screws behind it. I assume that's where I would start.
