Kitchenaid Ice maker has stopped making ice. Water dispenser still works and filter has been changed. Came on this forum before and was able to find link to trouble shoot optics. Cannot find that any longer. Can anyone post that for me? (light flashes red twice with pause when open. When flapper door held down, solid red light) Would like to confirm that is the problem before spending $100 on an optics board. Have never done a repair like this before.

Also see several people found an ice clog as culprit to their ice maker problems. Where is the line that feeds the ice maker? Not seeing it.

Thanks for the help.
