What temperature should I set my refrigerator and freezer to?

The factory recommended set points are 37°F (3°C) for the refrigerator and 0°F (-18°C) for the freezer. The refrigerator set point range is 33°F to 45°F (0°C to 7°C), and the freezer set point range is -5°F to 5°F (-21°C to -15°C). Wait at least 24 hours between adjustments and recheck temperatures before making other adjustments. (Page 19)
