Carrier HC43SB116 Motor

This Carrier HC43SB116 is a professional-grade 1/2 HP blower motor engineered for high-static residential and light commercial HVAC systems. Operating at 120V with a 1075 RPM rating, this 4-speed motor allows for precise airflow balancing across heating and cooling cycles. The CCW lead end rotation (Counter-Clockwise) and standard 5-5/8 inch diameter frame ensure a direct fit for Carrier, Bryant, and Payne air handlers and furnaces. As a Permanent Split Capacitor (PSC) design, it provides reliable torque and consistent performance under varying load conditions. For field technicians, this unit is a drop-in replacement for the HC43SB116A, maintaining identical electrical characteristics and mounting footprints to reduce downtime during emergency repairs.

• Multi-Speed Versatility: The 4-speed taps provide flexibility for system-specific CFM requirements, optimizing heat exchange efficiency.
• OEM Compatibility: Specifically designed to replace Carrier HC43SB116 and HC43SB116A models without requiring bracket modifications.
• Rugged PSC Design: Built with high-temperature insulation and ball bearings to withstand the rigorous duty cycles of modern air distribution.
• Standardized Frame: Features a 48-frame (5.6" diameter) chassis, making it compatible with most universal motor belly bands or torsion flex mounts.

What capacitor does the HC43SB116 require?
Most 1/2 HP 1075 RPM motors in this class require a 10 MFD / 370V run capacitor. Always verify the specific microfarad rating on the new motor's nameplate before installation to prevent winding failure.

Can I use this to replace a 3-speed motor?
Yes, the Carrier 4-speed motor can replace a 3-speed model by capping off the unused speed lead with a wire nut. This provides an additional tuning option for static pressure issues.

How do I confirm rotation direction?
This motor is CCWLE (Counter-Clockwise Lead End). If your existing blower wheel requires CW rotation, verify your specific housing orientation, as improper rotation will significantly drop airflow and cause the motor to overheat.
