You might also notice that there is a leak coming from the door and this could also be caused by the gasket being worn, damaged, or no longer aligned properly.

Had to drag the full freezer out from the wall to expose the name plate, got the Model # and S/N and found the key on the partselect website in minutes. It was cheap so I got two. Other than FEDEX not knowing my address correctly, when I finally got the key it worked fine. Not a problem anymore.
