What are refrigerator freezer temperatures?

When you set the temperature of your refrigerator and freezer, proper settings will help ensure the longest possible storage life for your food. Control the settings of your refrigerator and freezer to find the balance between the energy use and your food preservation. Although the factory defaults may vary by manufacturer, the overall temperature recommendations remain the same.

Refrigerator Temperature

Your refrigerator will ship from the factory at approximately 2.78 degrees Celsius. Always keep your refrigerator temperature set below 4.44 degrees Celsius to protect your food from bacteria. Food freezes at 0 degrees C or colder, so a setting of 0.556 degrees C or higher eliminates food loss due to freezing.

Freezer Temperature

Most household freezers are shipped from the factory at 0-17.778 degrees Celsius. Set your freezer anywhere from -15 degrees to -9.44 degrees Celsius. Colder temperatures may increase the chances of freezer burn on foods that are not adequately wrapped and sealed.

Conserving Energy

You can reduce the amount of energy that your refrigerator and freezer consume by setting the temperature controls to a more conservative setting. Your refrigerator will be more energy efficient when you set the dial to 2.22 to 3.33 degrees Celsius. Maximise your freezer's efficiency by setting it to 0 to 5 degrees Fahrenheit. Ensure the seal on the doors is intact to maintain a consistent temperature.

Monitor Temperatures

Place thermometers inside the refrigerator and freezer. Position them in the front of the appliance, selecting an area that is easy to see. Check the temperature reading at least weekly to ensure that your refrigerator and freezer are maintaining a consistent temperature.
