I had it narrowed down to either an ice maker or the water valve. I wasn't sure so I emailed Appliance parts and they said it was likely an ice maker and the gave me the part number for my refrigerator. It came the next day and I swapped it out in about 15 minutes. It started working right away. I now have ice. The only thing different was that the electrical connection was a little longer then my old one. That made it a little harder to install but it is always better to have more length then not enough.
