Check the temperature

While you have an empty fridge, check to make sure your freezer is set at the right temperature. According to the FDA, your freezer should be 0 degrees Fahrenheit (-18 degrees Celsius). 

Put an appliance thermometer in your freezer for a few minutes, then give it a check. If your freezer isn’t in the proper temperature range, adjust the settings before putting your food back in there.
