The Right Refrigerator and Freezer Temperature Settings

37°F for the fridge and 0°F for the freezer keeps food safe and the compressor running efficiently. Here's why those particular numbers matter.

Getting the fridge and freezer temperatures dialed in correctly protects both your food and your energy bill — and the targets are simple to remember.

Fridge: 37°F (3°C)

Run it too warm and food spoils faster; too cold and you'll freeze produce while wasting energy.

Fix: Target 37°F and confirm it with a separate fridge thermometer, since the display isn't always accurate.

Freezer: 0°F (-18°C)

Zero degrees keeps food safely frozen without forcing the compressor to overwork.

Fix: Set it to 0°F and only go colder if you're storing food for the long term.

Give It Time and Airflow

The digital display updates instantly, but the actual cabinet takes closer to a full day to stabilize.

Fix: Wait 24 hours between any adjustment and keep the interior vents unblocked.
