what temp to set freezer

The recommended temperature for a freezer to keep food safe is at or below 0°F (-18°C) . However, the temperature may need to be adjusted by a few degrees to account for factors like location, humidity, or outside temperatures. The typical factory setting for a freezer is 0°F (-18°C) . It is important to keep perishable items cold, but not so cold that vegetables lose their freshness. If the freezer is fully filled, food may block the internal air vents, making it harder to distribute cold air throughout the freezer. Therefore, it is recommended to keep the freezer around 75–80% full to help retain cold air. It is also important to avoid putting too much food in the freezer, as chilled air must be able to move evenly around the food to keep it frozen. Finally, it is recommended to use an appliance thermometer to find the ideal temperature for the freezer and update the settings accordingly.
