In-Door Ice Maker Not Working?

I just purchased a new Kenmore Elite side by side 30 cu ft refrigerator freezer. I have water in the door, but the ice maker will not work. The water dispenser works. Sears hooked up the unit, but I had to wait 24 hours for ice to work, it is now 72 hours and still doesn't work. My old Kenmore made ice on the same connection. Help.
