Touch Pad or Control Board

I had a repairman out to look at my refrigerator and he said it was the control panel, I was going to order that and replace it, but I asked the order desk and they showed me a touch pad that has a circuit board on the back of it, I was wondering if that could be the problem, No ice or water when I push the buttons on the touch pad Part number 1477970. Any help would be appreciated.
