Without power, the refrigerator section will keep food cool 4-6 hours, depending on the kitchen temperature. Block ice can be added to keep the refrigerator cold if there's a delay in getting the power back on.
A full, well-functioning freezer unit should keep foods frozen for 2 days. A half-full unit should keep things frozen about 1 day. Dry ice can be added to the freezer unit. Be careful not to breathe the fumes or handle with bare hands--dry ice will burn your skin.
