Carrier LA11XA045 Blower Wheel

The Carrier LA11XA045 Blower Wheel is a precision-engineered draft inducer wheel designed for high-efficiency Carrier, Bryant, and Payne gas furnaces. This genuine OEM component features a 4.5-inch diameter with a 5/16-inch bore and is optimized for clockwise (CW) rotation at speeds up to 3400 RPM. As a veteran technician knows, maintaining the correct static pressure and combustion air ratio depends on the integrity of the furnace inducer wheel. The 1 3/8-inch height and lightweight build ensure a balanced rotation that prevents premature inducer motor bearing failure and reduces vibration noise during the heating cycle.

Constructed from durable materials to resist corrosion in high-heat environments, the LA11XA045 facilitates the safe expulsion of combustion gases through the heat exchanger. This replacement blower wheel is essential for restoring factory-specified airflow in models such as the 58RAV, 373LAV, and 376CAV series. When the original wheel becomes clogged or brittle, it compromises the draft pressure switch, leading to furnace lockout. Installing this OEM HVAC blower wheel ensures your client's system meets original performance curves and maintains reliable ignition cycles throughout the winter season.

• OEM-Grade Precision: Designed for an exact fit on 5/16-inch shafts to eliminate wobble and noise.
• Optimized Airflow: Engineered clockwise rotation maintains the specific static pressure required for draft pressure switch closure.
• Corrosion Resistance: Built to withstand the acidic condensate often found in high-efficiency furnace exhaust streams.
• Broad Compatibility: Fits a wide range of Carrier-produced draft inducer assemblies, reducing the need for universal substitutes.

• How do I confirm the rotation of the LA11XA045? This wheel is designed for clockwise rotation when viewing from the hub side. Always verify the motor rotation before installation.
• What are the physical dimensions for fitment? The wheel measures 4.5 inches in diameter, approximately 1.375 inches in height, and fits a standard 5/16-inch inducer motor shaft.
• Will this fix a noisy inducer motor? If the noise is caused by a cracked, unbalanced, or debris-filled wheel, replacing the wheel with an OEM LA11XA045 will restore quiet operation.
