More Information
Summary:A refrigeration appliance (10) includes an ice maker (50) disposed in a fresh food compartment (14). An air handler assembly (100) conveys cooling air through the ice maker (50). An insulated air duct (152) is disposed between an evaporator (186) and a fan (164) for preventing the migration of ice from the evaporator (186) to the fan (164). The insulated duct (152) has an opening extending from an end adjacent the evaporator (186) to an end adjacent the fan (164). A lower inner wall of the air duct (152) has a first ramped portion (156a) on the end adjacent the evaporator (186). In another example, the icemaker (350) includes a sensor assembly (370) positioned to detect a level of ice (352) in the ice bin (354). The sensor assembly (370) includes an emitter (372) for sending photons along a predetermined path, and a receiver (374) for detecting the photons when the photons are reflected off an object disposed in the predetermined path.
