Kfcs22evms00 I see no screws, hex or otherwise, after removing deli tray support struts and crisper drawer.
When you look at the endcap there are 3 openings that if you look inside them you will see a 1/4" screw in each one of them. You would need to remove the screws to take the endcap off.
Please advise of which tabs, and screws need to be released so that this endcap can be removed.
To remove the endcap, you will need to remove the crisper bins and the glass above the pantry drawer. Remove the pantry drawer and cover. Once out there are 3 screws that will allow you to take the endcap off. If you slide the rail out you will see screws that hold the rail on in which you will want to remove. Once the endcap is off you can remove the back piece by taking out of the clips and on the back part of the endcap there are 3 clips that hold the rail. Push in and pop the rail out. This rail will be able to twist off the selector. Then you can pop the selector knob off.
