The Carrier LA11AA005 Blower Wheel is a critical component for draft inducer motor assemblies in mid-to-high efficiency gas furnaces. Maintaining precise flue gas extraction, this 4-inch diameter wheel is engineered for high-temperature durability and peak aerodynamic performance. Featuring a 1.5-inch width and a 28-blade "squirrel cage" design, it ensures balanced operation and reduced vibration within the inducer housing. This genuine replacement part is designed for a 5/16-inch (.31") bore and operates with a clockwise (CW) rotation as viewed from the hub end. Designed as a direct cross-reference for the P441-1146, it also supersedes older LA11AA004 and LA11AA006 iterations. For contractors, this wheel is essential for resolving restricted airflow or mechanical noise issues in Carrier, Bryant, and Payne heating systems. Using the integrated single set screw, ensure the wheel is securely seated on the motor shaft to prevent slippage and optimize furnace inducer efficiency. Key Benefits: Compatible with a wide range of Carrier, Bryant, and Payne furnace inducer motors. Engineered with 28 precision fins to maximize static pressure and flue gas venting. Durable metal construction resists warping and thermal degradation during long heating cycles. Perfectly balanced 4-inch OD wheel reduces strain on the inducer motor bearings. Direct replacement for part numbers P441-1146, LA11AA004, and LA11AA006. Common Questions: What are the symptoms of a failing inducer blower wheel? Technicians typically look for unusual rattling or screeching sounds coming from the inducer motor, which often indicates an unbalanced or loose wheel. Weak airflow or system lockout due to pressure switch failure can also point to a clogged or damaged LA11AA005. What is the bore size for the LA11AA005? This wheel is designed for a 5/16" (.31 inch) motor shaft and includes a set screw for secure mechanical attachment. Does this wheel rotate clockwise or counter-clockwise? The Carrier LA11AA005 is a clockwise (CW) rotation wheel when viewed from the hub end. Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
