No ice was being made

I looked up the refrigerator on the internet and found this website. I got the diagram of the parts of the icemaker and found that the valve must be defective because no water was coming up to the icemaker.
I ordered the part which came the next day. Took out the screws, conected the water line to the new part. moved the electrical connection to the new part and we had ice. Saved a lot of money that the plumber would have cost.
