There are little clips that the cover snaps into. It's easier to replace if you slide the cover and the piece it attaches to out. Just open the drawer and pull the cover forward. The clear cover is attached to a piece of white plastic that slides in and out on a small track. Remove the the cover and mounting piece, it's easier to unclip the cover when it's out of the refrigerator. Unclip the old and attach the new. Slide the assembly back in making sure the white plastic piece is in the track.
