Works on my freezer.  I have had a couple of episodes over the years of the door popping open on my upright freezer after I leave if the food on the shelves is sticking out too far.  The door appears shut, but the magnetic seal isn't enough to stay closed with the pressure of being shut against the food in the wrong place and the door gradually pops open.  No problem if you spot it immediately, big problem if a day goes by.  :)
