What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model AEPF313716AA — B13400704ABS is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Goodman equipment which lists the model number AEPF313716AA — B13400704ABS.

My AC fan is not spinning. What part do I need?

A fan that does not spin, spins slowly, or makes grinding or squealing noises needs a new motor. Grinding means the bearings have failed. Squealing means the bearings are dry. No spin with a humming sound means the capacitor may be the issue. Check the motor capacitor before replacing the entire motor.

Is this blower motor compatible with Bryant or Payne systems too?

Many Goodman parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

The Goodman B13400704ABS 3/4 HP Variable-Speed Blower Motor is the genuine OEM ECM (electronically commutated) motor for the Goodman/Amana AEPF313716AA air handler. This variable-speed motor ramps airflow smoothly to match the system's heating and cooling demand, delivering quieter operation, improved humidity control, and lower electrical consumption than a standard PSC motor. It is the heart of the air handler's blower assembly and the most common high-value replacement when airflow drops or the blower fails to start.

Specifications

Motor Type: Variable-speed ECM

OEM vs. Generic

This OEM ECM ships with the correct motor module and programming for the AEPF control board, so airflow tables, CFM staging, and diagnostics behave exactly as the factory intended. Generic ECM retrofit kits require reprogramming or external modules and frequently mismatch the board's torque/CFM commands. The OEM motor is plug-and-play with the existing harness and mounting.

Installation Difficulty

Rating: Hard (4/5). Involves removing the blower assembly, swapping the motor and module, transferring the wheel, and verifying the 16-pin and power connections. Professional installation recommended. Plan 1–2 hours. Disconnect power and allow capacitors to discharge before servicing.
