A freezer can safely remain off for about 48 hours if it is full and unopened; for a half-full freezer, this window shortens to around 24 hours. Keeping the doors closed helps maintain the cold temperature. If the power has been out longer, check the food’s temperature; items above 40°F (4°C) should be discarded to avoid risk of foodborne illness.
