All freezers should be in the 0 to 8 degrees Fahrenheit (approximately -18 degrees to -13 degrees Celsius) range. However, when you first turn on the freezer, or put a lot of food into it, it may take up to 24 hours for the freezer to reach this temperature range.
The freezer temperature needs to be at 0Â°F or lower. If you are going to be freezing a large amount of food at one time, you can turn the freezer setting lower so that added food does not raise the temperature of already frozen food in the freezer.Temperature affects the size of the ice crystals in the food.he freezer temperature needs to be at 0Â°F or lower.
