how long can a freezer be turned off
Keep the refrigerator and freezer doors closed as much as possible to maintain the cold temperature. The refrigerator will keep food safely cold for about 4 hours if it is unopened. A full freezer will hold the temperature for approximately 48 hours (24 hours if it is half full) if the door remains closed.nd the temperature inside the fridge will never reach room temperature in those 10 hours. When it is really hot in summer, it might spoil after 2 hours outside the fridge, but otherwise it takes much longer. Cheese, food in jars, sauces, leftover cooked food: none of these are more sensitive to spoiling than milk.
