Whirlpool ice maker not making ice

Hello,
I have a Whirlpool gsf26c5exb00 refrigerator and the ice maker is not making ice. I have replaced the Water Inlet Valve and the Optics in the ice maker. The water dispenser on the door puts out water, but the Ice maker is still not getting water and making ice. I have the proper water pressure to the system. I am at a loss for ideas? Any help is greatly appreciated.
Thank you.
