What temperature should my fridge be?

Concerns & risks

You were trying to keep groceries fresh, but the milk keeps going sour before the date, and you wonder if your fridge is warm.

Everyday mishaps add up.

Causes & evidence

Keep the fridge at 40°F or below and the freezer at 0°F. See food storage times.

What to do

1. Use an appliance thermometer.
2. Fridge 40°F or below.
3. Freezer 0°F.

Common mistakes: Common mistakes: trusting the dial. Numbers on a fridge dial don't always show actual temperature. Put an appliance thermometer in the middle of the fridge and check it after several hours. Don't block the vents with food. Leave space for cold air to move. Keep the door closed as much as possible. Store milk on a shelf, not the door, which is warmer. Check door seals for gaps; a dollar bill test helps: close the door on a bill and see if it slides out easily. If the fridge can't stay cold, it may need repair. Clean up spills promptly, and wipe shelves regularly so smells don't build up. Throw out spoiled food weekly.

Speed Man tip: Don't overpack.

Wrap-up: Thermometer. 40°F. 0°F.
