The Carrier 52CQ500664 Indoor Fan Blade is a heavy-duty, steel centrifugal blower wheel designed for high-static pressure applications in Carrier, Bryant, and Payne air handlers and PTAC units. Engineered for precise HVAC part compatibility, this 8.6" x 8.8" double-inlet component ensures optimal CFM delivery and balanced rotation to minimize vibration in residential and commercial evaporators. As a genuine OEM replacement fan, the 52CQ500664 is critical for restoring heat transfer efficiency and maintaining designated airflow across indoor evaporator coils. Techs should verify the 1/2" or 3/4" bore size and rotation direction during installation to prevent motor strain. Whether you are addressing a noisy blower or a total airflow failure, this blower wheel assembly provides the structural integrity required for 24/7 climate control cycles. Ensure all set screws are torqued to manufacturer specs to prevent slippage on the motor shaft.

Key Benefits

• Direct OEM Fit: Ensures seamless integration with Carrier air conditioning and heat pump systems without field modifications.
• Durable Steel Construction: Resists warping and corrosion, maintaining structural balance in high-humidity indoor environments.
• Optimized Airflow: Precision-pitched blades provide the necessary static pressure for consistent indoor air distribution.
• Vibration Reduction: Factory-balanced design reduces mechanical wear on motor bearings and housing components.

Common Questions

Is the Carrier 52CQ500664 compatible with PTAC units?
Yes, this blower wheel is frequently used in 52C series PTAC units and select air handlers; always verify the model number against the factory parts list.

What causes this fan blade to fail?
Common issues include debris accumulation causing imbalance, set screw loosening, or surface oxidation in heavy-use commercial environments.

Does this include the blower motor?
No, this is the 52CQ500664 fan blade assembly only. The motor must be sourced separately if the shaft is damaged or the motor is seized.
