A refrigerator includes a water system and a valve. The water system is configured to direct water to a dispenser or an ice maker. The valve includes a valve body, an inlet port, and a clutch. The valve is configured to connect the water system to a water source. The inlet port is configured to receive a tube to establish fluid communication with the water source and to engage a nut to secure the tube to the inlet port. The clutch is disposed between the inlet port and the valve body and is configured to slip in response to an applied torque to the inlet port exceeding a threshold.

A refrigerator appliance or ice making assembly, as provided herein, may include a body and an ejector. The body may include an ice mold for receiving and freezing water. The ice mold may define a discrete first compartment and second compartment within which water freezes. The first compartment may define a first cube profile. The second compartment may be axially-spaced apart from the first compartment and define a second cube profile. The second cube profile may be different from the first cube profile. The ejector may be rotatably disposed above the first cube profile and the second cube profile to motivate ice from the first and second compartments.

A refrigerator includes a cabinet, a door, an ice making room, a cool air supply duct connecting the evaporation chamber to the ice making room, an ice maker, a cool air guide duct that guides cool air from the ice making room toward the ice maker, and an ice bin below the ice maker to store ice. The ice maker includes an ice tray including cool air guide ribs, and an ice separating guide covering a front surface of the ice tray and a portion of a top surface thereof in which the cool air guide ribs extend from one side of the ice tray toward the other side and are spaced apart from a front surface of a tray body toward a rear surface, and bottom parts of the cool air guide ribs are spaced apart from a bottom part of the cool air guide duct.

A refrigerator includes a cabinet defining a storage space, a door configured to open and close at least a portion of the storage space, and an evaporator configured to generate cold air. The refrigerator also includes a first ice maker provided in the door, a second ice maker provided in the storage space and configured to be covered by the door when the door is closed, a first cold air guide configured to guide the cold air to the first ice maker, and a second cold air guide configured to guide the cold air to the second ice maker.
