How can I stop the icemaker on a GE fridge from overflowing water?
I threw in the towel and called an applicance guy. He looked at evertyhing I did, and could see no broken parts. Putting our heads together, we came to the conclusion that its a design flaw. We wound up doing two things - 1) We opened up the area at the bottom of the water funnel to water into the mold faster and 2) I made a small "fence" at the back of the funnel out of aluminum duct tape to stop water from overflowing. These two things together seem to have done the trick.
