Have you tried putting about half a cup of water into the tray to get the cycle to restart?

Again I am not a pro, just an appliance owner. If it makes and disperses ice when you put in a little water, it sounds like the dual water valve to me. I had this exact problem and replaced the dual water valve a few days ago (see post called something like Kitchenaid Superba icemaker no water) and it is working again. I left instructions for the repair as it applies to my Kitchenaid refrigerator.

Good luck.

The part number will vary by model. Click on "Find Parts" above and it will take you to a page which asks for information like maker and model number. Once you find the exact model there will be schematics by section like icemaker, door, etc. You then get a split screen with the blow-up drawing at the top with each item numbered. At the bottom of the screen the parts correspond to these numbers. Many of the parts are pictured so you can find the old one when you open up the refrigerator.

When I received the dual water valve, it came with pretty good instructions about how to swap it out.

Good luck. My question would be why you never had ice if you purchased it new? Unlikely that the water valve was defective from the factory.
