What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WGPH4543AMAB — B1376857 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 WGPH4543AMAB — B1376857.

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 fan 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

The OEM B1376857 is stamped to Goodman's exact bolt pattern and arm length, ensuring the fan blade sits at the correct height in the venturi. Generic universal mounts often require drilling and shimming, which can throw off blade clearance. For a clean drop-in repair, OEM is the safer choice.
