I thought that I needed to repair the water supply. But it all looked OK. I had turned the power off for a few minutes hoping to clear any false info from the numerous power outages. And with hours of research, I found some info about the door switch on top of the freezer. It suggested placing a magnet above the switch to silence the noise. This did the trick. Shortly after I heard the ice maker filling. I tested the water feed, and it was working. I then ordered a new switch and replaced it. To my dismay, the door was still chiming without the magnet in place. I examined the magnet that was in place on the top of the door and found a lot of dust. I removed and cleaned it. After putting it in place, the chiming stopped. Now all is working great. Maybe just some cleaning will repair it?????
