Abstract: A refrigerator includes a filter, a receiver, a manifold, and a cam. The filter has a handle extending therefrom. The receiver defines a cavity configured to receive the filter. The manifold is configured to engage an opposing end of the filter relative to the handle via axial rotation of the filter. The manifold is configured to pivot upward to transition the filter to an activated position. The manifold is configured to pivot downward to transition the filter to a deactivated position. The cam is configured to interfere with the handle in response to partial axial rotation of the filter to prevent the filter from pivoting upward to the activated position. The cam is configured to provide clearance for the handle in response to full axial rotation of the filter to facilitate the filter pivoting upward to the activated position.

Abstract: An ice making and dispensing system suitable for making and dispensing ice through the refrigerator compartment door of a bottom freezer refrigerator. The ice maker and ice cube storage bin are located in an insulated sub-compartment in the refrigerator compartment. The insulated sub-compartment is maintained below 0° C. for forming and storing ice cubes. The insulated sub-compartment can be positioned adjacent the freezer compartment and can be cooled by below 0° C. air from the freezer compartment or from an auxiliary evaporator.

Abstract: An ice making and dispensing system suitable for making and dispensing ice through the refrigerator compartment door of a bottom freezer refrigerator. The ice maker is positioned in an insulated sub-compartment in the refrigerator compartment maintained at a temperature below 0° C. An insulated ice cube storage bin and ice dispenser are positioned on the refrigerator compartment door for dispensing ice cubes through the face of the refrigerator compartment door.

Abstract: An ice making and dispensing system suitable for making and dispensing ice through the refrigerator compartment door of a bottom freezer refrigerator. The bottom freezer refrigerator includes an automatic ice maker in an insulated module positioned outside the freezer compartment. The insulated module can be mounted to the exterior of the refrigerator cabinet. An ice cube storage bin can be provided in the insulated compartment or on the inside of the refrigerator compartment door. A passage can connect the insulated module with the ice dispenser on the refrigerator compartment door.

Abstract: An ice making and dispensing system suitable for making and dispensing ice through the refrigerator compartment door of a bottom freezer refrigerator. The ice maker and ice cube storage bin can be positioned in an insulated module in the refrigerator compartment opposite an ice dispenser positioned on the refrigerator compartment door. The insulated module is maintained at temperatures below 0° C. for forming and storing ice cubes. Air ducts from the evaporator compartment or an auxiliary ice maker evaporator can be provided to maintain below 0° C. temperatures in the insulated module.
