I used Appliance Pro for trouble shooting and couldn't be positive whether it was the ice maker or the water valve unit. I ordered both parts. Significant in the process "Samantha" on live chat couldn't find the model number and had me send a photo of the information plate. That saved the day!
The icemaker replacement was the easiest access so I replaced it first after viewing the tutorial video. That solved the problem. At the same time a friend had a similar type problem and using a local repairman solved it for $280 while my repair cost $102 . Thank you Appliance Pro.
