Amana-Goodman PP3587 Motor

The Amana-Goodman PP3587 Blower Motor is a heavy-duty, 1/2 HP replacement designed for demanding residential and light commercial HVAC applications. Operating at 115V with a maximum speed of 1075 RPM, this three-speed blower motor provides precise airflow control to match system static pressure requirements. It is a direct OEM-spec replacement for 20046603S and 20046610, ensuring a drop-in fit for Amana, Goodman, and Rheem air handlers or furnaces. The motor features a 1/2” diameter by 4” length shaft and utilizes a 10 MFD 370V capacitor (sold separately) for optimal torque. Built with Class B insulation and a 48-frame diameter, this sleeve-bearing motor is engineered for CCW rotation but is electronically reversible to accommodate various blower housing configurations. For technicians, the 36” lead wires and pre-drilled Rheem mounting holes simplify field installation while the internal automatic thermal overload protector ensures reliable operation under high ambient conditions.

Key Benefits for HVAC Professionals:

• Broad Compatibility: Serves as a primary HVAC blower motor replacement for Goodman, Amana, and Rheem equipment.
• Multi-Speed Versatility: Features 3-speed taps (7.5, 4.5, and 3.0 Amps) to fine-tune CFM delivery.
• Rugged Construction: Equipped with an automatic thermal protector and Class B insulation to withstand internal heat build-up.
• Flexible Mounting: Includes standard mounting patterns and a length-sufficient 36-inch lead set for quick wiring in tight cabinets.

Common Technical Questions:

Is the PP3587 a direct replacement for my older Goodman motor?
Yes, this unit is the designated Amana-Goodman replacement motor for part numbers 20046603S and 20046610. Always verify the voltage (115V) and shaft dimensions before installation.

What rotation is required for this model?
The PP3587 is configured for CCW rotation (counter-clockwise) from the lead end, but it is electronically reversible to meet specific fan wheel requirements.

Which capacitor should be used with this motor?
To maintain the proper inductive load and motor efficiency, a 10 MFD 370V capacitor is required for operation.
