How do automatic defrost freezers work?

The Auto Defrost feature uses a heater inside the fridge to periodically warm the appliance during the defrost cycle. Any ice build up melts and drains away through the hole at the bottom of the cabinet. This water is then collected in a tray behind the appliance and then evaporated.
