I have never like the dark, woodgrain Masonite panel. Too dark. I used some re-cycled tub surround plastic cut to fit the door, bolstered the space behind it with some scrap plastic and some bubble wrap.
The end result is a clean, white
fridge door that is easy to keep clean.
There are two pieces, one for the door panel and one across the top to hld the lower one in place. I hope the pics get through.
