The door also includes an outer casing comprising a thermally insulated wall that defines a freezer chamber and a front panel rotatably mounted to the outer casing of the door such that the front panel of the door permits access to the freezer chamber.

Abstract: A refrigerator appliance having a temperature controlled drawer with improved temperature control is provided. A sealed system including a compressor, an evaporator, and an evaporator fan may be configured for cooling the fresh food chamber. A controller is configured to operate the evaporator fan when the compressor is off in order to increase the temperature of the temperature controlled drawer. Additionally, or alternatively, a secondary fan may be attached to the temperature controlled drawer and may be selectively operated by the controller to circulate air from the chilled chamber through the temperature controlled drawer. In this manner, the temperature of the temperature controlled drawer may be more precisely controlled regardless of whether the compressor is running.

Abstract: A refrigerator appliance is provided including a freezer chamber divided into a first compartment and a second compartment by a removable mullion. A refrigeration system includes a single evaporator coil having a first evaporator section in series with a second evaporator section. The first evaporator section is positioned in the first freezer compartment to maintain the temperature in that compartment at a fixed, low temperature (e.g., 0° F.). The second evaporator section is positioned in the second freezer compartment which is a “convertible” compartment capable of maintaining temperatures between the freezer and fresh food compartment temperatures (e.g., between about 0° F. and 37° F.).

Abstract: A refrigerator appliance is generally provided herein. The refrigerator appliance may include a cabinet, a secondary liner, and a circulation duct. The cabinet may include an internal liner defining a freezer chamber and a fresh food chamber. The secondary liner may be positioned at the fresh food chamber. The secondary liner may define a sub-compartment in fluid isolation from the freezer chamber and the fresh food chamber. The circulation duct may extend within the sub-compartment in fluidly-isolated thermal communication with the sub-compartment. The circulation duct may define an air passage in fluid communication with the freezer chamber.
