The dual inlet valve was the problem. The hardest part of the repair was moving the refrigerator so we could unplug it. The whole job took about 25 minutes and that includes the time we spent emptying and reorganizing the shelves. I love AppliancePartsPros.com. We have used this website to fix our oven, washer, dryer and now the ice maker. Thank you AppliancePartsPros!
We only used one screwdriver and that was only used to open the back panel of the refrigerator.
