Some Samsung refrigerators have a known defect where the seal from the manufacturer around the ice room is leaky which may result in air getting into the area around the ice maker. As the refrigerator cools, that air turns to frost and can jam up the functions of your ice maker and the "auger" which is the piece that actually turns to dispense the ice when you push the ice button.
In most cases, I've found that these situations are remedied with a new ice maker and a re-seal of the ice room.

Your serial number's 8th and 9th digit will confirm what parts will be needed based on the manufacturing date. Some will require just the ice maker itself and others will need the ice maker, drain tube, y-clip kit, and main control board.
