I got on the chat line with a very helpful AppliancePartsPros.com and received various test suggestions and troubleshooting videos. The final decision was that I needed to replace the ice maker. I then ordered the ice maker from APP and proceeded to install it. My problem was still not solved! I again removed the ice maker unit and focused on the water supply itself. Even though I had previously inspected the water line input to the ice maker, I decided to try and clean this port. It turned out that there must have been a small piece of calcium in the end of the water line port causing the water to spray outside of the ice maker while refilling. Though I probably did not need the new ice maker, I decided to keep it anyway since the refrigerator was a few years old. In no way do I fault APP! They have bailed me out many times on various appliance issues.
