I replaced the ice maker and in 20 minutes I had ice. A mirror to see the two screws and a screwdriver were the only tools I needed. The screws are loosened only, not removed. Lift up and slide out old ice maker. Be sure electric plug to refrigerator is unplugged. The bottom of the ice maker can burn your fingers so be sure you have cut it off by raising the ice lever and then give it 30 minutes to cool down. You will need to plug the new ice maker in. Turn on water and plug refrigerator into outlet. It will take a few minutes to start but it did.
