Fasco D923 Motor

The Fasco D923 is a robust 5.6-inch diameter condenser fan motor engineered for demanding outdoor HVAC applications. This Permanent Split Capacitor (PSC) motor features a multi-horsepower design, allowing it to function as a 1/3 HP, 1/4 HP, or 1/5 HP motor depending on the capacitor selection. Operating at 208-230V and a nominal 1075 RPM, it utilizes a single-speed configuration with reversible rotation to accommodate various blade pitches. Built with Class B insulation and ball bearings, this totally enclosed air over (TEAO) motor is designed for heat dissipation and protection against environmental contaminants. The 1/2-inch diameter shaft extends 5.0 inches, providing compatibility with standard HVAC replacement motor mounts. When replacing an OEM condenser motor, ensure you match the frame size and amperage draw to maintain system efficiency and prevent overheating in high-ambient conditions.

• Multi-HP versatility allows this unit to replace three distinct horsepower ratings, reducing inventory requirements for service calls.
• Ball bearing construction supports high-temperature operation and allows for mounting in any orientation (all-angle mounting).
• Reversible lead wires permit quick field changes between clockwise and counter-clockwise rotation.
• TEAO enclosure prevents dust and moisture from entering the motor windings, essential for residential and commercial condensing units.
• Automatic thermal overload protection prevents winding failure during voltage fluctuations or mechanical binding.

Common Technical Questions

What capacitor is required for the Fasco D923?
This motor typically requires a 7.5 MFD / 370V capacitor when used at its maximum 1/3 HP rating, though you should always verify the requirements listed on the specific nameplate for the application's load.

Can this motor be used in a vertical-shaft down position?
Yes, the ball bearing system integrated into the D923 is designed for all-angle mounting, making it suitable for horizontal, shaft-up, or shaft-down installations in outdoor units.

How do I change the rotation of this motor?
Rotation is modified by swapping the two sets of reversing leads located in the wiring harness, allowing for simple adaptation to the existing fan blade configuration.
