## Abstract

A refrigeration appliance includes a cabinet that defines a cabinet outlet and a cabinet inlet in fluid communication with a freezer compartment. A door is pivotally coupled to the cabinet. The door defines a door inlet in fluid communication with the cabinet outlet and a door outlet in fluid communication with the cabinet inlet when the door is in a closed position. An icemaker compartment is disposed in the door. The icemaker compartment is fluidly coupled with the freezer compartment. A retainer is at least partially disposed in each of the door inlet and the door outlet. Each retainer includes a rim that defines ribs. Each rib is spaced apart from adjacent ribs. A gasket is coupled to each retainer. Each gasket includes an abutment surface that abuts a cabinet surface when the door is in the closed position to seal airflow passages between the freezer compartment and the icemaker compartment.

## Claims

### Claim 1

An ice making system for an appliance door, comprising:
an icemaker compartment;
an air duct coupled to the icemaker compartment, wherein the icemaker compartment is in fluid communication with a door inlet via the air duct;
a return duct coupled to the icemaker compartment, wherein the icemaker compartment is in fluid communication with a door outlet via the return duct;
a first retainer coupled to the air duct and configured to be disposed at least partially in the door inlet;
a second retainer coupled to the return duct and configured to be disposed at least partially in the door outlet, wherein each of the first retainer and the second retainer includes a rim defining ribs and an insertion wall with deformable coupling features to engage and interlock with the air duct and the return duct, respectively; and
a gasket coupled to each retainer, wherein each gasket includes an abutment surface configured to abut a cabinet surface to seal airflow passages defined by the door inlet and the door outlet, respectively.

### Claim 2 (depends on 1)

The ice making system of claim 1, wherein the rim extends perpendicular to the insertion walls and are configured to extend over a surface of a door side panel.

### Claim 3 (depends on 2)

The ice making system of claim 2, wherein the ribs protrude outward from an engagement surface on the rim, respectively, to maintain a space within the gaskets and prevent a vacuum suction effect.

### Claim 4 (depends on 1)

The ice making system of claim 1, wherein the insertion walls of the first and second retainers each include opposing lateral wall portions that define the deformable coupling features.

### Claim 5 (depends on 4)

The ice making system of claim 4, wherein the deformable coupling features are defined on central sections of the opposing lateral wall portions.

### Claim 6 (depends on 4)

The ice making system of claim 4, wherein notches are defined on the opposing lateral wall portions, the notches defining lengths of the deformable coupling features.

### Claim 7 (depends on 1)

The ice making system of claim 1, wherein the deformable coupling features define a plurality of teeth configured to interlock with an edge of the air duct and an edge of the return duct, respectively.

### Claim 8 (depends on 1)

The ice making system of claim 1, wherein the insertion walls of the first and second retainers each include first and second lateral wall portions opposing one another, and wherein the first lateral wall portion defines a first pair of notches and the second lateral wall portion defines a second pair of notches, and further wherein the first pair of notches and the second pair of notches permit deformation of sections of the first and second lateral wall portions, respectively, towards one another.

### Claim 9

An appliance door, comprising:
a panel defining an inlet and an outlet adjacent to the inlet;
an icemaker compartment fluidly coupled to the inlet via an air duct and fluidly coupled to the outlet via a return duct;
at least one retainer disposed adjacent to at least one of the inlet and the outlet, wherein the at least one retainer includes an insertion wall extending through the panel and a rim extending over the panel and defining ribs, wherein the insertion wall includes first and second lateral wall portions, and wherein the first lateral wall portion includes a first pair of notches and the second lateral wall portion includes a second pair of notches, and wherein the first pair of notches and the second pair of notches permit deformation of sections of the first and second lateral wall portions towards one another; and
at least one gasket coupled to the at least one retainer with a U-shaped coupling portion extending over an outer edge of the rim, wherein the at least one gasket is configured to compress toward the at least one retainer, and wherein the ribs maintain a space within the at least one gasket to prevent a vacuum suction effect.

### Claim 10 (depends on 9)

The appliance door of claim 9, wherein the sections of the first and second lateral wall portions each define a coupling feature.

### Claim 11 (depends on 10)

The appliance door of claim 10, wherein the coupling features define a plurality of teeth configured to interlock with an edge of at least one of the air duct and the return duct, and wherein the first pair of notches and the second pair of notches allow for deformation of each coupling feature as each tooth of the plurality of teeth engages with the edge.

### Claim 12 (depends on 9)

The appliance door of claim 9, wherein the at least one retainer includes a first retainer disposed adjacent to the inlet and a second retainer disposed adjacent to the outlet, and wherein the at least one gasket includes a first gasket coupled to the first retainer and a second gasket coupled to the second retainer.

### Claim 13 (depends on 9)

The appliance door of claim 9, wherein the rim defines a width larger than a width of the U-shaped coupling portion.

### Claim 14 (depends on 9)

The appliance door of claim 9, wherein the ribs protrude outward from an engagement surface on the rim and away from a surface of the panel.

### Claim 15

A door vent sealing assembly for an appliance door, comprising:
a duct;
a retainer including:
an insertion wall at least partially defining an aperture, wherein the insertion wall defines deformable coupling features on opposing sides of the retainer, and wherein the deformable coupling features each define a plurality of teeth extending between a pair of notches, the pluralities of teeth being configured to interlock with an edge of the duct; and
a rim coupled to the insertion wall, wherein the rim extends perpendicular to the insertion wall and outward from the aperture; and
a gasket having a coupling portion for receiving the rim to couple the gasket to the retainer and a sealing member spaced from and extending over the rim.

### Claim 16 (depends on 15)

The door vent sealing assembly of claim 15, wherein the rim defines a width larger than a width of the coupling portion.

### Claim 17 (depends on 15)

The door vent sealing assembly of claim 15, wherein the insertion wall includes opposing wall portions, and wherein the deformable coupling features are defined on central sections of the opposing wall portions.

### Claim 18 (depends on 15)
