What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model AEPF426016CA — 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 AEPF426016CA — 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 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.

OEM vs. Generic

This genuine Goodman OEM ECM motor ships pre-programmed with the correct airflow profiles and connector pinout for the AEPF426016CA control board. Generic ECM replacements require a separate module and field programming, and a mismatched profile can cause incorrect CFM, nuisance lockouts, or comfort complaints. The OEM motor is plug-and-play and keeps the factory warranty intact.

Installation Difficulty

Hard (4/5) — High-value ECM component with a multi-pin harness and blower-deck removal. Disconnect and lock out power, allow capacitors to discharge, transfer the blower wheel, then reconnect the 16-pin control and 5-pin power harnesses. A licensed HVAC technician is strongly recommended; plan 60–90 minutes.
