## Abstract

A refrigerator includes a refrigerator cabinet, an ice maker disposed within the refrigerator cabinet, and an ice mold in the ice maker. The ice maker is configured to provide cooling air from a cool air source along a bottom side of the ice mold during freezing of water to make ice. The ice maker is further configured to provide warm air from a warm air source along the bottom side of the ice mold to facilitate harvesting of the ice. The warm air source may be a refrigeration compartment disposed within the refrigerator cabinet. The ice maker may be disposed within the refrigeration compartment or the freezer compartment. The ice maker may be configured to make clear ice. The ice mold may be fixed in place during the harvesting of the ice.

## Claims

### Claim 1

A refrigerator comprising:
a refrigerator cabinet;
an ice maker disposed within the refrigerator cabinet;
an ice mold in the ice maker;
