There are several possible reasons why your RS2556SH is no longer making ice. I would suggest checking to make sure the temperature is still set below 0°F (-2°F is recommended); the water lines are connected and unkinked; the valves are turned on; and the Ice Off function has not been activated by pressing the Ice Type button. Try pressing the "Test/Reset" button on the bottom of the icemaker.
If the problem persists, your refrigerator may require service. To initiate service through Samsung, 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.
