The back wall and bottom of my GSC23KSW side by side freezer was coated with ice and fan was making a clicking noise. When I looked inside the ice maker I found the plastic "chute" inside the ice container. This happened before. The "chute" (part # 867) was moved out of position and water ran down back of freezer. I've taken everything out of freezer, all the ice I can see, left it open for an hour or so and fan noise stopped. Is the plastic "chute" supposed to be held in position somehow? Do I need to remove back of freezer liner to get ice build up away from fan? Thanks for your help
