Takes longer than three hours for ours. Freezer will be getting cold, frig takes quite a bit longer. 10 to 12 hours before we get to 37/38 degrees.. If history causes you to expect the frig to be colder within three hours, and it is not happening, a common problem (which has happened to us) is a cooling unit failure. I would give it more time before messing with anything.
