Every 24 hours or so a timer brings on an element which quickly melts off any excess ice, without raising the temperature in the cabinet. This water drains to the outside and evaporates. Also the circulating air in the cabinet passes through a drier which removes moisture, and reduces icing.

Frost free freezers use a lot of energy, that's how they do it.
