An ice making assembly for a refrigerator appliance includes a resilient mold defining a mold cavity and a heat exchanger in thermal communication with the resilient mold to freeze water and form one or more ice cubes therein. The ice making assembly also includes a lifter mechanism positioned below the resilient mold for selectively deforming the mold and raising the ice cubes formed therein. A resilient seal is sealingly engaged with the lifter mechanism and the heat exchanger, whereby an air-tight seal is formed between the lifter mechanism and the resilient seal and between the heat exchanger and the resilient seal.

An ice maker includes an ice mold having an inner surface and an outer surface. The inner surface of the ice mold is configured to retain water for forming ice cubes in the ice mold. The ice mold includes a plurality of ice lobes each shaped to form a respective ice cube in the ice mold. A heater assembly is positioned on the outer surface of the ice mold. In some embodiments, each of a plurality of heating elements of the heater assembly is aligned with a corresponding lobe of the plurality of lobes for supplying heat to ice cubes formed in the lobes for releasing the ice cubes from the ice mold. In some embodiments, the heater assembly includes a heater having a ceramic substrate and one or more electrically resistive traces and electrically conductive traces thick film printed on the ceramic substrate.

A system for manufacturing clear ice products is provided. The system includes a freezing module, a demolding module, and a converting station. The freezing module includes a frame comprising a plurality of levels, a plate freezer provided at each level, and at least one mold provided for placement on each plate freezer and suitable for receiving water. A control frame is provided associated with each plate freezer and is movable from an elevated position to fill position. In the fill position, the control frame is at least partially disposed within the mold. One or more circulation pumps are associated with each control frame for circulating water in the mold to release air bubbles as the water freezes. The demolding module removes the mold from the freezing module and removes formed ice from the mold. The converting station converts the formed ice into a clear ice product.

An ice maker for forming ice having a refrigeration system, a water system, and a control system. The refrigeration system includes a compressor, a condenser, an ice formation device, and a condenser fan comprising a fan blade and a condenser fan motor for driving the fan blade.
