Here are the pics of the evaporator coil in the freezer. I have a feeling the problem is the frozen chunk of ice to the right of the coil. The fan was running fine. Could this be the problem for both the freezer temp AND the ice maker not making ice?
Thanks so much for all your help. I have contacted KitchenAid and scheduled a service call. They confirmed that if it is a sealed system issue the parts are free, but labor is not covered nor is the $125 fee. This is the second time they will have checked the sealed system and the fridge is only 4.5 years old. What a lemon.
Again, thanks for all your support and persistence! It is greatly appreciated!
