How long can you leave a freezer unplugged?

Bear in mind that a refrigerator continues to insulate even when it is off, so cold food inside a refrigerator can remain adequately cold for about 4 hours or even up to 6 hours, depending on the refrigerator itself, the ambient temperature, and the number of times the refrigerator door is opened. The food in the freezer section will keep longer - 1 to 2 days (if the freezer is full). See Related Links.
