The PP3405 is an industrial-grade OEM-style replacement motor engineered for high-tonnage Goodman, Amana, and Janitrol condensing units. Acting as the primary "muscle" for the outdoor cooling cycle, this 1/3 HP motor drives the fan blade to pull massive volumes of ambient air through the condenser coils, facilitating the critical heat rejection required for large-tonnage systems. Designed for residential and light commercial split systems, the PP3404 is the central component that maintains precise head pressure, protecting your compressor from thermal stress. With its dual 50/60Hz capability, it restores factory-spec airflow to 3.5 to 5-ton systems that have suffered from motor burnout.

Key Features

• Exact OEM Specification: The PP3405 is a direct-fit replacement for Goodman part number 10584523, ensuring 100% mechanical compatibility with factory motor mounts.
• Multi-Frequency Versatility: Engineered to operate seamlessly on both 50Hz and 60Hz power, providing a reliable solution for various international and domestic power grids.
• Universal Rotation Logic: Features simple electrical reversal leads, allowing the motor to be configured for either clockwise (CW) or counter-clockwise (CCW) fan blades.
• Internal Safety Monitoring: Built with an automatic reset thermal overload protector that prevents the motor from burning out during extreme summer heatwaves.
• Totally Enclosed Air-Over (TEAO): The sealed motor housing protects internal windings from rain, dust, and debris, significantly extending the part's service life in harsh environments.

🛠️ HVAC Depot Pro Tip

"The Capacitor Upgrade"—When upgrading to the PP3405, it is industry best practice to install a brand-new 7.5 MFD / 370V (or 440V) run capacitor. Reusing an old capacitor is the leading cause of new motor failure, as it cannot provide the consistent phase shift required for 1/3 HP torque. Before final assembly, verify that the water slinger is positioned correctly on the shaft to prevent moisture from traveling down into the motor bearings during heavy rain.
