Samsung should get in touch with you through the forums or you can call them at 1-800-Samsung. I had to open my own forum posting before I heard back, but they arranged service and sent someone out to fix it at no cost to me. That made me feel much better about my purchase.
After a few years of consistently defrosting the Ice Maker and applying ALL the Samsung recommended engineering updates, I finally just turned down the water pressure to as low as possible and still fill a glass of water from the door. This would best be described as the water valve to the Refrigerator being "Just Barely On". Defrosted the ice maker one last time. That was almost a month ago. Still, no Iced Over defrost vent! WooHoo. Hope it was really that simple all along. I'll keep reporting but things are looking good. Worth trying if you are having this issue.
That's great news! We really appreciate your tenacity to get this matter under control.
When the refrigerator was under warrenty, the ice maker needed to be replaced. The replacement Ice maker is now having the same problem the original did. I need it serviced and think this should be covered by Samsung as it is an obvious design defect.
