I believe I answered this one on another page of unsolved problems HERE. Thanks for the model number. If the ice slots inside the ice maker are empty try pouring tap water in the slots and allow the water to freeze. If after the water freezes the ice drops into the ice bucket and the ice maker does not refill this would indicate that the side of the=> W10408179 Water Inlet Valve is defective on the side that controls ice maker water supply. If the ice maker just sits there and does nothing this would point to a defective ice maker. Depending what is wrong with the ice maker will determine what parts are replaced. Here is a list of those parts here=> Kenmore Refrigerator Model 106.51552104 Ice Maker Parts and if need you may be able to find a complete ice maker replacement by asking. Most people don't like replacing ice maker parts. I am here should you have questions or comments, Sea Breeze
