Ice maker not making ice

My kitchen aid ice maker is not working. if you put ice in the bin it will dispense it, so the motor is fine there, and the water in the door works. if you push in the little flap on the left the light on the right blinks twice. the little teeth on the ice maker are in the up position and there is no water or ice in the ice maker. someone told me it might be the valve-Inlt, would that be the first place to start or is there a way to tell what part it is for sure right off that bat and save time?
