Product review (4 stars): Worked for model RF28HMEDBSR
It is exactly what it says it is. An OEM replacement. Much cheaper to DIY rather than call a service technician. Could not find valid instructions on how to replace mine. Only online videos were different models that had the spring visible on the outside. I had to do some trial and error with ours and found the spring inside the verticle devider. See the attached photo. Had to remove the entire assembly from the door. 2 screws on the middle hinge. Swing the devider out until it can be slid up and unplug it. Once it's off the devider can be split in half with a standard screwdriver on the side with the hinges. You will see small groves where it snaps together.
This was for model RF28HMEDBSR. Good luck
