Hi, I bit long shot as the post is from 2012 but I will give it a try anyway..
I have the same problem with ice not being made and water never freezes in top compartment but freezes ok in the bottom part of the freezer.
I have removed the evaporator fan but cannot detach the fan blade.. any idea how to detach the fan blade from the motor? Also is there any way how to test if the motor is faulty or not?
Thanks
