According to the Food and Drug Administration, your fridge should be set at or below 40 F (4 C). Your freezer should be set at 0 F (-18 C).

34Â°F - 40Â°F is the ideal refrigerator temperature range. Some Web sites just say under 40Â°F, but not so cold to freeze fresh foods. Dairy products and meats keep best at the low end of the temperature range.A freezer should be set at 0Â°F, or lower, if possible.If the temperature gets warmer than +5Â°F, ice cream will be too soft and won't keep well. A properly working food freezer will operate in the range of -10Â°F to +2Â°F, and may go up to around +8Â°F briefly during the defrost cycle if it is of the frost free type. freezer should be set at 0Â°F, or lower, if possible.
