I have a 25 cubic foot side by side Kitchenaid refrigerator. Occasionally, actually quite frequently now, the ice dispenser door will not open when the ice dispenser pad is depressed to deliver ice. Ice will the clog the dispenser chute and slowly melt thus dripping water out of the ice dispenser. I looked at a parts list for my fridge and see a control card and a door motor. Should I replace one, the other or both? Is his the right fix?
