Replaced ice maker and tray assembly. Tried calling Samsung but not very helpful.Talked to local repair people and they state that is a problem with Samsung refrigerators. They no longer service Samsung products. Stated the housing around the ice maker needs to be sealed to prevent air from infiltrating the internal workings of ice maker. Looked at videos of ice maker replacement and they were very helpful. Care must be taken to not bend refrigerant tube extending into ice maker. Also had to take time to dry internal housing of ice maker before sealing external housing with silicone. Encourage some instructions to help DI Y's in replacing parts. Relative easy replacement but took time to get ice maker dry.
