Freezer door water line

I need to replace/ repair the water line that comes out of the bottom of the door. It has been cut off flush, and there appears that there is no extra plastic line to pull out of the opening.

How do I take the freezer door apart to access the water line to splice in a new piece? I cant see any screws to get the inside plastic shelving out, and I think I might end up wrecking the door if I am not careful.

If the water line in the door is available, it is a job to take the door off and feed a new line through the cabinet. Try calling a technician. I’ve heard Sears services that area 1-800-4my-home
