The B13400252S is a genuine OEM replacement motor specifically engineered for high-efficiency Goodman and Amana residential condensing units. Serving as the primary "muscle" for the outdoor cooling cycle, this motor drives the fan blades to pull ambient air across the condenser coils, acting as the critical thermal management component that prevents compressor overheating. Designed as an 8-pole motor, it provides the high-torque, low-speed airflow required for ultra-quiet operation in premium split systems. Choosing this genuine factory part over a universal alternative guarantees that the internal starting torque and specific 825 RPM profile match your unit's original factory engineering for maximum SEER efficiency.

🛠️ HVAC Depot Pro Tip
"The 5 MFD Essential"—Whenever replacing an 8-pole motor like the B13400252S, it is industry best practice to install a brand-new 5 MFD / 370V run capacitor. An old or weakened capacitor is the leading cause of new motor "cycling" or humming, as it cannot provide the necessary phase shift to keep the motor running at full torque. Before final assembly, verify that the water slinger is positioned correctly on the 1/2" shaft to prevent moisture from traveling down into the motor bearings during heavy rain.
