The 12002744 is a genuine OEM refrigerator evaporator fan motor kit for Whirlpool, Maytag, KitchenAid, Jenn-Air, Amana, and Kenmore side-by-side and top-freezer refrigerators. This evaporator fan motor is the critical component that circulates cold air throughout the refrigerator and freezer compartments, ensuring even temperature distribution and efficient cooling. The motor is located in the back of the freezer compartment behind the evaporator cover panel, where it draws air over the evaporator coils and distributes the cooled air through vents to both the freezer and fresh food sections. The motor kit is constructed from durable materials including a permanent magnet synchronous motor or shaded pole motor (typically 115V AC, 60Hz, 3-8 watts), metal mounting bracket with pre-drilled holes, three-terminal electrical connector (two 1/4-inch terminals and one 3/16-inch terminal for power and ground connections), ground wire with terminal, 2-wire harness for electrical connection, and precision-balanced motor shaft (typically 5/16-inch diameter) for fan blade attachment. The motor measures approximately 2-3 inches in diameter and 2-3 inches in length, weighing less than 1 pound. The motor operates at variable speeds (typically 1500-3000 RPM) depending on cooling demand, controlled by the refrigerator's electronic control board or thermostat. The 12002744 replaces older part numbers and features improved motor windings for longer life, enhanced bearing design for quieter operation, better thermal protection to prevent overheating, and upgraded electrical connections for reliability. The evaporator fan motor operates continuously during the cooling cycle: when the compressor runs, the control board sends power to the fan motor; the motor spins the fan blade at high speed; the fan draws air from the freezer and fresh food compartments through return air vents; air passes over the cold evaporator coils, where heat is removed and the air is cooled; the cooled air is blown back into the freezer and fresh food compartments through supply air vents; this continuous circulation maintains even temperatures throughout the refrigerator; the motor cycles on and off with the compressor, running only when active cooling is needed; during defrost cycles, the fan motor stops to prevent warm air circulation. Common failure causes include normal wear from age and continuous operation (typically 8-12 years lifespan), bearing failure causing noise and reduced airflow, motor winding failure from electrical surge or overheating, ice buildup on fan blade causing motor strain and failure, frost accumulation blocking airflow and overloading motor, electrical connection failure from corrosion or loose connections, or manufacturing defects. When the evaporator fan motor fails, symptoms include refrigerator or freezer not cooling properly, frost buildup in freezer, loud grinding, squealing, or rattling noise from freezer, fan not running when compressor is on, uneven cooling (freezer cold but fresh food warm, or vice versa), excessive frost on evaporator coils, refrigerator running constantly without reaching temperature, or fresh food freezing. The 12002744 is a complete motor kit that includes everything needed for installation and restores proper air circulation and cooling. Important: Always unplug the refrigerator before working on the evaporator fan motor. This is a moderate repair requiring removal of freezer contents, ice maker, evaporator cover panel, and fan blade, plus careful electrical connections.
