ABSTRACT:
An ice maker including freeze and harvest controls is disclosed. The evaporator includes a unitary evaporator and ice mold. A compressor and condenser cool the evaporator to freeze ice on the mold in a normal refrigeration cycle and the mold is defrosted by hot gas to harvest ice from the ice mold. The temperature of the ice mold and the liquid line temperature of the condenser are sensed to control the length of time of the ice forming cycle.
