what temp is safe for refrigerators
Ensure that doors have a good seal and close tightly to maintain the temperature and the efficiency of the unit. Additionally, keep doors closed as much as possible. Keep a back-up appliance thermometer in the unit in case of a power outage. If the refrigerator is still 40Â°F when the power returns, the food is safe. The food should not be consumed if the temperature is held at 40Â°F for more than two hours.
