The old one didn't work so well any longer. The glass shelves had already been replaced once, the pull-out trays were cracked and difficult to pull out, and the lid for the butter tray was taped on with red duct tape. Home Depot had a sale on a nearly identical model Whirlpool and we are definitely constrained by size. Unfortunately, we require the door open from the right side. The side that the door hinge is normally found on. No problem, mounting holes are conveniently provided for the hinges along the left side.
