After watching many YouTube videos I finally found one where the gentleman determined that the ice cube tray in his Samsung refrigerator was cracked and not twisting the way it should to let the ice cubes drop out. Water then gets added to the tray over the ice cubes, causing it to overflow. I looked at the underside of mine and sure enough, it was cracked in the back. I ordered a replacement from AppliancePartsPros and had the new tray installed in 10 minutes. There are two Phillips screws that need to be removed at the top front of the ice cube maker and the unit slides out and down. You unclip the wiring harness to remove the whole thing from the fridge and then depress a lever on the ice maker to slide the motor assembly out sideways and replace the tray. Assemble in reverse order. We now have proper ice cubes again and no leaks!
