A:Answer Hello! While we would be unable to give the difference between a none Whirlpool model, we can advise model WZF79R20DW has The Fast Freeze Option helps you chill large amounts of food fast at just the push of a button. How it works: This option freezes large amounts of food fast, by driving freezer temps 10 degrees colder than the lowest setting.
A temperature alarm notifies you when the freezer's temperature rises to help you monitor the ideal environment for your frozen foods.
Frost-free defrost automatically prevents frost build-up, so you'll never have to empty the freezer for a manual defrost again.
Forget the ice trays. With the optional icemaker available on all Amana® top-freezer refrigerators, you can enjoy cold, refreshing beverages like smoothies and iced tea.
Thank you for your inquiry about our Whirlpool® appliances.
