I'm having the same problem and have since I purchased the refrigerator. I defrost the entire thing every 6 months to prevent problems, but now the ice maker doesn't work at all. I called out a tech and he confirmed it is a design problem where condensation builds up and freezes over the ice maker. It's $700 to fix the problem and the tech can't guarantee I won't need to have it done in another couple years. It's just a bad design. It's highly flawed.
Samsung needs to make this right by sending me the parts, at no cost, so I can get my ice maker repaired or they need to refund the entire purchase amount of the refrigerator. The latter is preferred.
Update...we have had a technician come out 4 times to repair and inspect the ice maker, which is freezing up and also has frost around the outer seal.
Visit 1: Informed us our 14 month old refrigerator needed 4 new parts. Ordered brand new ice maker, door flap, clips, and another part.
Visit 2: Different tech installed parts.
1 month later, Ice machine iced up again. Ice cubes were now sticking together.
Visit 3: Second tech returned, tried to get replacement. informed by Samsung the clips were not installed and this was required before a replacement could be issued. Ordered clips.
Visit 4: First tech returned and installed clips.
1 WEEK later, ice machine is iced up again and ice cubes sticking together.
Call to warranty claim said that only 2 repairs were made and so I did not qualify for a replacement.
Visit 5: Second tech returned. Informed by Samsung that clips were installed "incorrectly" - they should have been at a 90 degree angle and they were installed at 89 degrees. Clips are in the back of the refrigerator.
Also informed by Samsung that the filler tube was sticking out too far into the refrigerator (also in back)- it should be sticking out 1/16" max, and the "jagged edge" was causing the problem. It was manufactured this way, and I have no idea what that has to do with the outside seal icing up.
Tech had to slide out refrigerator and pull the tube further out to correct the issue (REALLY).
The tech was shaking his head the whole time. You really can't make this up. It's clear they KNOW there is an issue and want to do as much as possible to avoid it costing them money.
