Carrier HC39SB115 Blower Motor

The Carrier HC39SB115 Blower Motor is a high-efficiency Direct Drive PSC Motor engineered for consistent airflow in residential and light commercial forced-air systems. Operating at 115V with a 1/4 HP output, this 4-speed motor provides 1075 RPM performance to meet original equipment specifications. As a Permanent Split Capacitor design, it utilizes a 7.5 MFD at 370V capacitor (sold separately) to maintain high torque and energy-efficient operation. This 42-Frame motor features a durable rolled steel housing, sleeve bearings for quiet operation, and internal thermal protection to prevent overheating during continuous-duty cycles. The HC39SB115 is the direct replacement for HC37SB116, ensuring a drop-in fit for Carrier, Bryant, and Payne air handlers and furnaces. With a Counter-Clockwise (CCW) rotation from the lead end and a standard 1/2-inch shaft, it delivers the exact mechanical load matching required for OEM system balance.

• Direct OEM Interchange: Replaces legacy HC37SB116 and P251-2505 units without bracket modifications.
• Multi-Speed Flexibility: 4-speed taps allow for precise CFM adjustments to match heating and cooling load requirements.
• Industrial Build: NEMA 42-frame construction with Class A insulation and sleeve bearings designed for air-over applications.
• Optimal Performance: 1075 RPM rating ensures proper static pressure overcoming in standard ductwork configurations.

Is the HC39SB115 a direct fit for older HC37SB models?
Yes, the HC39SB115 blower motor is the factory-authorized replacement for the HC37SB116. It shares the same 42-frame dimensions and 1/4 horsepower rating for seamless installation.

What capacitor is required for this 115V blower motor?
This motor requires a 7.5 MFD / 370 VAC run capacitor. Always replace the capacitor when installing a new motor to ensure proper starting torque and to prevent premature winding failure.

Can this motor be used in CCW and CW applications?
No, this specific model is a dedicated CCW rotation (Counter-Clockwise) from the lead end. Verify your existing fan blade or blower wheel orientation before purchase.
