Thanks for the question. There are several factors that can effect the ability of the icemaker to produce ice, in particular the availability of water to fill the tray, and the temperature of the freezer once the tray is filled with water. First, make sure the Ice Off button on the control panel has not been pressed. Next, try pressing the Test button on the bottom of the icemaker, which should cause the tray to rotate then fill with water. For the water to freeze, the freezer temperature should be set to -2°F or colder. You can also press the Super Freeze button on the control panel to help speed the freezing process.
If the tray did not fill with water, check the water supply valve to make sure it is on all the way, and make sure the line is not bent or kinked. If you have an external filtration system installed, make sure the filter is not clogged. Samsung recommends setting the refrigerator temperature to 38°F; if set too cold the water line could freeze. It may be necessary to press the Test button more than once when the water line is first installed to bleed air from the line.
If the icemaker still won't fill with water or rotate to dump the ice, it may require service. Please submit an online service request through the link below, or call 800-SAMSUNG to speak with an agent who will be happy to assist you.
