What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WGPH4530AMAA — 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 WGPH4530AMAA — 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 motor mount 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 B1376857 Motor Mount Arm is the OEM support bracket that secures the condenser fan motor in Goodman WGPH4530AMAA 2.5-ton packaged units. This stamped-steel arm holds the motor centered over the condenser coil and ties into the fan-deck assembly so the blade spins true. A bent, cracked, or corroded mount arm lets the motor sag and the blade wobble, causing vibration, noise, and accelerated bearing wear — replacing it restores solid, quiet support.

Specifications

Type: Condenser fan motor mount arm / support bracket
Material: Stamped, coated steel
OEM Part Number: B1376857
Fits: Goodman WGPH4530AMAA and compatible package units
Mounts: Factory bolt pattern on fan deck and motor

OEM vs. Generic

The OEM B1376857 matches the exact length, bend, and bolt-hole spacing your unit requires so the motor sits at the correct height and the blade clears the grille. A generic bracket rarely matches the geometry and can leave the blade off-center. At this price point, OEM is the obvious choice.

Installation Difficulty

Easy to moderate. Support the motor, remove the bolts from the old arm, transfer the motor to the new arm, and re-bolt to the factory holes. Verify blade-to-grille clearance before restoring power. Always disconnect power first.

My AC fan isn’t spinning. What part do I need?

Is this motor mount compatible with Bryant or Payne too?

Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers.

Should I use OEM or aftermarket for my Goodman motor mount?
