Quick answers to questions about ordering, compatibility, and installation.
The B13400251S is a genuine OEM replacement motor specifically engineered for Goodman, Amana, and Janitrol residential condensing units. Serving as the primary "brain" for your outdoor unit's airflow, this motor drives the fan blades to pull ambient air across the condenser coils, facilitating the critical heat rejection required for the refrigeration cycle. Designed for high-efficiency split systems, this motor ensures your compressor operates within safe head-pressure limits. Choosing this genuine factory part over a universal alternative guarantees that the internal starting torque and 1.0 Amp power profile match your unit's original engineering for maximum component life.

🛠️ HVAC Depot Pro Tip
"The 5 MFD Essential"—Whenever replacing a 1/6 HP motor like the B13400251S, 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.
