Abstract
Provided is a method and system for forming ice pieces with an ice maker that includes a mold defining a plurality of cavities for receiving water to be frozen into ice pieces. A processor controls delivery of a refrigerant to freeze water received in the plurality of cavities into ice pieces. A freeze signal transmitted by a temperature sensor embedded within the mold is received by the processor, the freeze signal indicating that a temperature of a portion of the mold adjacent to the temperature sensor has reached a freeze temperature where the water in at least one of the cavities has achieved a frozen state to initiate harvesting of the frozen ice pieces. Defrosting a system evaporator can also be coordinated with operation of the ice maker.
