The vacuum on the fridge door seal is too great
Q: The vacuum on the fridge door seal is too great.
A: Cause: Air inside a fridge or freezer “shrinks” as it gets colder. This can sometimes create suction, which makes open the door difficult. If the door is closed quickly or slammed shut, air will be forced out and it may take several minutes for the vacuum to be released, after which the door can be opened normally.
