Carrier HC45AE118 Blower Motor

The Carrier HC45AE118 Blower Motor is a high-performance OEM replacement motor designed for direct-drive applications in Carrier, Bryant, and Payne furnaces and air handlers. This 3/4 HP blower motor operates on a standard 115V single-phase power supply at a nominal speed of 1075 RPM. Featuring a versatile 4-speed design, it allows for precise airflow tuning to meet specific system static pressure requirements. Built with a NEMA 48 frame and a 5.6-inch diameter, the motor utilizes Counter-Clockwise (CCW) rotation (facing the lead end) and includes a specialized 1/2-inch by 4-inch shaft for secure blower wheel attachment. This permanent split capacitor (PSC) motor is engineered for continuous duty, ensuring reliable air distribution and thermal regulation across the heat exchanger. As a factory-authorized part, it maintains the original equipment’s efficiency ratings and mounting specifications, including belly band mounting compatibility, which simplifies field installation and reduces mechanical vibration during high-static operation.

• Exact OEM Fit: Direct replacement for Carrier part number HC45AE118, ensuring full compatibility with 58GFA and 58DXT furnace series without body modifications.
• Multi-Speed Versatility: The 4-speed taps provide flexibility for heating, cooling, and continuous fan speeds to optimize indoor air quality.
• Robust Construction: Designed with a 1/2" diameter flat shaft and a rugged 48-frame housing to withstand the demands of year-round HVAC operation.
• Optimized Performance: Maintains a 11.10 Amp rating at 115V to ensure your HVAC blower system operates within original design parameters.

Common Questions

What is the correct rotation for the HC45AE118?
This motor is a CCW (Counter-Clockwise) rotation motor when viewed from the lead/back end. Always verify your existing blower wheel pitch before installation to ensure proper airflow direction.

Is a capacitor included with this furnace blower motor?
This is the motor only. It typically requires a 10 MFD / 370V or 440V run capacitor (such as P291-1004). Technicians recommend replacing the capacitor whenever a new 3/4 HP 1075 RPM motor is installed to prevent premature failure.

Can this motor replace a 1/2 HP or 1/3 HP motor?
It is critical to match the horsepower and amperage of your original equipment. Upgrading to a 3/4 HP motor from a lower rating can cause excessive airflow, noise, or electrical issues if the system ductwork and control board are not rated for the increased load.
