1 Maintain your refrigerator between 34Â°F and 40Â°F. Refrigerator thermometers are available to help monitor the temperature inside the appliance. See more on thermometers.  Use food quickly, and don't expect food to remain high-quality for the maximum length of time.
The ideal refrigerator temperature range is 1Â°-4.5Â°C (34Â°-40Â°F) . Bacterial and mold growth are considerably slowed down at these temperatures, thus retarding food spoilage. Since water freezes at 0Â°C (32Â°F), this prevents fresh foods from freezing, although when the temperature is at the low end of the range, some areas in the refrigerator may be below the freezing point.
