Why is my freezer too cold?
There may be various reasons why your freezer is too cold. Fixing it might be as simple as setting the temperature to around 0°F (-18°C) or resetting your freezer. Allow 24 hours for the temperature to adjust. Defrost your freezer if you have excessive frost buildup, as this can lower the temperature.
Make sure the air vents inside your freezer are clean and not blocked by food items or you may end up with ice and frost buildup. If you have an ice maker that’s on but not hooked up to a water supply, this may be the reason your freezer is too cold.
