Replaced ice maker unit. 4 screws to remove cover on inside door. 2 screws for ice maker. Three connectors: ice maker on/off switch, LED light, wiring harness connector. A second person assisted by bracing the door for me, but not necessary to get the job done. I also used some cellophane and tape to cover the door opening for the 5 minutes it took to replace the unit. Again, not necessary, but it was quite warm out and it kept the freezer contents from thawing out. Appliancepartspros.com had exactly what I needed, easy to search, and shipped quickly.
