Model # RF4287HARS/XAA

Hi! please check the troubleshooting part of the manual. Hope it will help! https://manualsbrain.com/en/manuals/1290202/?page=39

Drain hole would be just under evaporator coils. You may have to remove cover on inside back freezer wall to access it.

First photo shows paddle assembly that can be purchased you need to got to Sears web site to find part # other wise you will have to buy the whole circuit board assembly hundreds more than the paddle assembly. The circuit board and paddle assembly is removed buy removing screw on inside of door and pulling it out be careful it seems strange but it just pops out. The paddle assembly slides on to the circuit board assembly look close and take your time to slide it off I thought I was going to break mine but did not and save me big money.
Second photo shows tab for water dispensing still there.
Third photo show ice dispensing tab broken and missing.
If you leave the assembly plugged in press the micro switch for the ice dispenser and see if it works most likely the tab has broken and is what hits the switch telling the door to open and ice dispensing screw to push ice to the door. Hope this helps

XAA is America and XAC is Canada part number DA97-08518D

Check that you ice maker is on, do you have ice in the bucket?
Check you ice drain is not plugged. Do you hear some humming noise when you push the ice dispenser? This could be a complex problem.

The lever is pretty much the switch, in a sense. Actually it acts as a "middle man/agent", as the actual "switch" should be located just behind the lever inside the door. Logically, the only reason that I can give as to why you are having this issue is due to forced wear and tear on the internal switch itself, commonly caused by people forcing the lever backward to trigger the "switch" in the act of getting ice. The node/knob on the internal switch could be depressed to the point that it will not pop back out as it normally should, or the harness/housing that it is inside of may possibly be worn if not broken to the point to where when the lever is engaged it moves the internal switch backwards until it stops against the backing of the inside of the door, making it hard if not sometimes impossible for the lever to full engage the "switch" in order to get a full flow of electricity through the wiring. One last theory is that through normal wear and tear, the wiring could be bad, be it due to shortage or moisture buildup inside the door of the fridge.

The whole unit must be removed and unplugged. There is a screw in the bottom near the dispenser opening. Remove this screwn and then take a butter knife and start prying the unit outword.

The lever that operates the microswitch may be broken and was on mine. This part is cheap plastic and breaks when over entended in the least. If the actuation lever is broken, you will NOT feel any resistance when pressing the Ice despenser and will push on through to dispense water. Problem is there is NO fix for this except replacement and Samsung will not pay for it.

I fashioned a piece of bailing wire in place of the lever that will act the same and have a little spring incase someone presses to hard with their cup/glass. Yes... its bailing wire and works great. You must drill through the middle of the broken support, fashion the wire, coat with super glue and put in position pretty quick.

If you find a small plastic piece on the floor and your ice maker stops dispensing.... I think I know your problem.

Buy Whirlpool

hi ggammon the dispenser is activated by the paddle that you place your glass against,then touching a micro switch .so i'd say you've got somthing amiss there and i would think only eyes on the ground can see what that is.i just said a prayer for you and you'll have to go back in there.in Gods service,tom

does it have a lockout on the despenser area that you can push to reactivate the despenser
