Abstract
A freezer includes a refrigeration surface that can be frozen, such as an evaporator surface, a heating device for heating the refrigeration surface, and a control circuit for controlling the operation of the heating device in accordance with a timer. The control circuit is configured to block the operation of the heating device for a time period that is defined by the timer. The timer is used to ensure that the refrigeration surface is only heated to defrost the freezer, if the refrigeration power requirement of the latter is low.
