Amana-Goodman 20046604S Blower Motor

The Amana-Goodman 20046604S Blower Motor is a high-performance 1/3 HP PSC motor engineered for precise compatibility with specific Goodman, Amana, and Janitrol air handlers and furnaces. Operating at 1075 RPM with a 208-230V rating, this multi-speed motor serves as a direct drop-in replacement for legacy part numbers 20046604 and 10759208. Designed for reliability in high-static environments, it features a standard NEMA 48 frame and requires a 5 MFD / 370V run capacitor for optimal torque and efficiency. As an OEM component, it ensures the internal wire harness and mounting tolerances align perfectly with the factory blower housing, maintaining the original CFM delivery and static pressure ratings of the HVAC system. This motor is essential for technicians restoring factory-spec airflow and thermal lift in residential split systems.

• OEM Direct Replacement: Engineered to match the exact physical dimensions and electrical load of Goodman furnace blower motors.
• Multi-Speed Capability: Allows for fine-tuning of HVAC blower motor speeds to meet specific system airflow requirements.
• Durable Construction: Features permanently lubricated ball bearings to reduce mechanical friction and extend the operational life of the assembly.
• Thermal Protection: Includes internal automatic reset thermal overload protection to prevent winding failure during high-heat cycles.

Common Questions

Does this motor include the run capacitor?
No, this unit requires a 5 MFD / 370V capacitor, which should be replaced alongside the motor to ensure proper phase shift and motor longevity.

Can this motor replace a 1/2 HP model?
No, you must match the 1/3 HP rating and 208-230V voltage exactly to avoid overheating the windings or failing to meet the required static pressure.

Is this a reversible rotation motor?
This motor is typically set for a specific rotation; always verify the CCW or CW lead configuration against your original blower wheel rotation before installation.
