Orman, on some models of the Samsung there is a drain tube for the defroster that they didn't extend the heater element down the tube far enough. This means that the drain tube freezes and the water can't escape down the tube and then overflows into the refer. Google it and there is a repair for it. I just used a piece of 14 gauge copper wire and extended it 4 inches down the tube. Problem solved. Marty
