Leaving the freezer door open too long is probably the most common. A worn or damaged gasket (the door seal) will allow warm air in and cold air to escape, contributing to freezer frost. Hot food ...

Inside the freezer, air is circulated by means of one or more fans. In a typical design cold air from the freezer compartment is ducted to the fresh food compartment and circulated back into the freezer compartment. Air circulation helps sublimate any ice or frost that may form on frozen items in the freezer compartment. While defrosting, this ...
