Product review (5 stars): Excellent product
The reason I had to replace this assembly was years of pushing to hard on the ice lever.  Eventually we broke the small internal switch that closes when the lever is depressed.  It only takes a slight pressure to activate the switch, but because of the inherent delay in the operation it is tempting to push harder.  Don't!
I bought the Samsung service manual and looked online to see how to remove the old assembly.  Yes, there is a screw on the underside of top that must be removed.  That is the easy part.  The instructions all indicate that the assembly front panel must be moved up and sideways to allow the assembly to be pulled outward.  Good luck.  I am pretty handy, but no amount of pushing in any combination of directions worked. I ended up putting a small screwdriver between the right side of the assembly panel and the door.  I managed to pry the panel far enough to allow the hidden panel ears to clear the door and the assembly popped right out.  Yes, I did scratch up the door, but the scratches are hardly noticeable.  After removal I looked all around the door opening and I couldn't see any way that the assembly could be removed using the instructions.  The ears that retain the assembly in the door are considerably longer than the gap between the assembly panel and the door frame.  Everything else about the replacement is straightforward .
