Product review (5 stars): Be sure if its 7 or 9
This a 9 cube ice maker which fits a Samsung RF 4287HARS/XAA. It should be noted that a 7 cube maker was also listed with the same part Number. I counted the holes on the side of my ice maker, after removing the ice tray to ensure mine was a  9 cube version. It took less than 10 minutes to install. Once installed I pressed the reset button for approx 15 seconds. I did not hear any chimes or noise. Approx 3 hours later I did hear some ice drop. I woke up to see many cubes in the tray.
