A:Answer Hi Betty,
I'm sorry to hear ice is falling behind the bin, which is likely occurring because the ice is piling too high in areas of the bin not "checked" by the feeler arm that signals when the bin is full to stop ice production. If you open and close the drawer slowly, the ice should be less likely to escape the bin. The most reliable solution is to turn the ice maker off by pressing the Ice Off button on the control panel when the level is ice is lower than the cutout area on the back of the bin. Simply press the Ice Off button again to turn the ice maker back on, as needed.
Thanks for the question,
Ms. Samsung
