What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model AEPF303616CA — 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 AEPF303616CA — 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 AEPF303616CA air handler. Variable speed motors ramp airflow up and down to match demand, delivering quieter operation, improved humidity control, and higher efficiency than standard PSC motors. This is the heart of the air handler's comfort and energy performance.

OEM vs. Generic

The genuine Goodman ECM ships pre-programmed with the airflow profile matched to your air handler and coil. Generic variable speed motors require separate modules and field programming, and incorrect profiles cause poor airflow, comfort complaints, and nuisance faults. For correct staging and efficiency, OEM is the right choice.

Installation Difficulty

Advanced (professional recommended). Requires disconnecting high-voltage power, removing the blower assembly, transferring the wheel, and connecting the ECM control harness. Improper handling of the motor module can damage it. We recommend a licensed HVAC technician.
