what temperature should freezer be

The recommended temperature for a freezer to keep food safe is at or below 0°F (-18°C) . This temperature range ensures that the food stays frozen and preserves it until it is ready to be cooked or reheated. It is important to keep the temperature constant, so it is recommended to place an appliance thermometer in the freezer and check it regularly. If the power goes out, it is important to keep the freezer door closed as much as possible to maintain the temperature. When the door stays closed, a freezer can keep food at a safe temperature for around 48 hours.
