My ice maker does not stop making ice. I have to manually shut it off, and then remember to turn it back on. When I move the ice level rod, I don't hear any clicks. What part do I need to replace, or do I replace the whole ice maker?

Also, the exit door for the ice does not close by itself. We have to push it closed otherwise we get frost build-up. Is there a fix for this?

Thanks in advance!
