Abstract
A refrigeration appliance includes a freezer compartment fluidly coupled to an ice maker compartment via an ice maker return duct. An internal sensor is positioned within the freezer compartment and configured to sense a first condition within the freezer compartment. An external sensor is coupled to said refrigeration appliance and configured to sense a second condition external to said refrigeration appliance. A return fan is positioned within the ice maker return duct. A controller is operably coupled to the internal and external sensors to receive sensed first and second conditions. The controller is configured to determine a differential between the sensed first condition within the freezer compartment and the sensed second condition external to said refrigeration appliance. The controller activates the return fan to blow air from the ice maker compartment into the freezer compartment in response to the differential.
