Checked water line and that was clear and flowed good. Husband used to repair appliances, so has experience. Knew it needed a new ice maker. However, when talking with Tech online and asking if the system included the wire harness, I was told it did. When it arrived it "did not" included the harness. Thankfully it worked when it was installed with the old harness. My suggestion is that you put this in the description and include the part #'s of the items for easy access.
