What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WGPH4543AMAA — 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 WGPH4543AMAA — 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 a genuine OEM support bracket for the condenser fan motor on the WGPH4543AMAA packaged unit. The mount arm bridges the motor to the unit's bracketry, holding the fan motor in correct alignment over the condenser coil. A corroded, cracked, or vibration-fatigued arm lets the motor sag, causing blade strike, bearing wear, and noise — replacing it restores proper concentric clearance for the fan blade.

OEM Part Number: B1376857
Fits Model: WGPH4543AMAA
Type: Condenser fan motor mount arm / bracket
Function: Positions and supports the fan motor
Brand: Goodman (genuine OEM)

OEM vs. Generic: The OEM arm matches the factory bolt spacing and offset so the motor and blade sit at the designed height and depth in the venturi. Bending a universal strap to fit risks misalignment, blade rub, and premature motor bearing failure. At this price, OEM is the obvious choice.

Install Difficulty: Easy (2 of 5). Disconnect power, support the motor, unbolt the old arm, transfer the motor to the new arm, and reassemble — about 20–30 minutes with hand tools. No refrigerant work involved.
