Product review (5 stars): Fix for RF4287HARS giving water when you want ice!
This fixed my Samsung RF4287HARS.  The symptom is that you press the ice dispenser paddle and get no ice but you can continue pressing that paddle back so that it contacts the water paddle and you get water.  The problem is that a plastic piece (an arm that attaches to the ice paddle and makes contact with the ice dispenser switch which is hidden up in the assembly) has broken off.  Without the arm, the ice paddle never makes contact with the switch -- and it turns out that arm is the only thing that restricts travel of the paddle so it's free to continue back to the water paddle.

Replacement is simple, pry out the whole digital control panel (I used a pocket knife on the lower edge of the front face and gently pried my way around the assembly).  Once you have it that control panel out, you'll see how this parts slides into it (there are two small tabs on the back of it that lock it in place.  Otherwise, it's just friction that you have to overcome.)

In the future, be gentle on the paddle as it's clearly a weak point to have this small plastic arm bearing all the force of the glass shoving into it.
