I was looking for the same answers last night and today discovered the answer. Provided your control box is the same as mine, there are four screw that have to be removed. The two hex screws on the inside of the fridge which you can see are obvious. The not so obvious are two screws behind the faceplate of the control box. See the following diagram.
Model ED25LFXGN00
Part number #3 is the screw on the left. There is another on the right hand side. In order to remove the face plate you have to pry it off from the top and work your way across the top edge. Then it will lift off. I have attached a couple of photos so you can see the back of the faceplate and the control box with the faceplate removed.
Hope this helps.
