The Perfect Freezer Temperature
Let’s focus on the recommended freezer temperature first. Yes, everything that contains water, which is all foods, freezes at 0°C (32°F), the freezing point of water. If you want your food to be safe to eat indefinitely, you’re looking at your freezer remaining at or below -18°C (or 0°F).
Signs of Temperature Problems With Your Freezer
Here are some of the signs of improperly-set freezer temperature
The formation of frost may be an indication that your freezer is set to too low a temperature. At an overly low temperature, the freezer may have a hard time removing moisture. If this occurs in the proximity of the door gaskets, which are rubber seals around the freezer door edge, it means they may be allowing air to leak into the freezer. Excess air inside a freezer causes freezer burn (more on this later). If there is a layer of ice all over the freezer interior, the door may have been left open.

What About Freezer Burn?
You’ve probably heard of freezer burn. It can diminish the taste and texture of food. Does it have anything to do with the coolness of your freezer? Absolutely not. Freezer burnt food is perfectly safe to eat, although it may have a diminished taste.
