Best Answer: Safe Refrigerator Temperature For safety, it is important to verify the temperature of the refrigerator. Refrigerators should be set to maintain a temperature of 40 Â°F or below. An appliance thermometer can be kept in the refrigerator to monitor the temperature.This can be critical in the event of a power outage. When the power goes back on, if the refrigerator is still 40 Â°F, the food is safe. Foods held at temperatures above 40 Â°F for more than 2 hours should not be consumed.Appliance thermometers are specifically designed to provide accuracy at cold temperatures.his can be critical in the event of a power outage.
