Ice does not dispense, motor is OK

[SIZE=4]My refrigerator does not dispense ice. I thought the motor was bad but I had that checked and it works fine. When you touch the ice dispense button nothing happens, no noise, no clicking, no ice! I took the motor off and it does work. I am guessing there is a switch that must be broken but I do not know were to start.[/SIZE]
[SIZE=4]Any advice?[/SIZE]
