ABSTRACT:
An ice making apparatus utilizes a single thermostat for energizing and de-energizing a mold heater which is utilized to free ice bodies from a mold. The thermostat has a narrow operating range so that the heater is de-energized substantially immediately after the ice body is free from the mold to enable harvesting of the ice bodies to be completed in a single revolution of an ejector blade. The short time during which the heater is on allows a subsequent freezing cycle to be completed faster and the single revolution permits the harvesting cycle to be completed faster in order to increase ice production of the ice maker.
