Greetings!
Thank you for your review. We are disheartened that the plastic parts, ice maker, and freezer didn't live up to your expectations.
I have shared a Samsung link and a video below that can help address the concerns with the ice maker.

The plastic parts are not covered by a warranty, if you need plastic parts replaced you may visit the website of our authorized distributor for the parts and accessories I have shared below.
