What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WGPH4560AMAB — 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 WGPH4560AMAB — 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.

Goodman B1376857 Motor Mount Arm

The B1376857 is a genuine OEM motor mount arm (mounting bracket) for the Goodman WGPH4560AMAB packaged air conditioner. This bracket anchors the blower/fan motor to the unit's mounting band or housing, holding the motor in correct alignment and absorbing operating vibration. A bent, cracked, or missing mount arm causes motor wobble, bearing wear, noise, and blade-to-shroud contact — making this an inexpensive but critical part to keep in spec.

Specifications

OEM Part Number: B1376857
Type: Motor mount arm / support bracket
Function: Secures and aligns the blower motor
Designed for: Goodman WGPH4560AMAB
Material: Stamped/formed steel
Brand: Goodman (OEM)

OEM vs. Generic

OEM mount arms match the exact bolt pattern, arm length, and offset of the factory motor band, so the motor seats at the correct depth and the blade is centered in the shroud. Generic or bent-to-fit brackets risk misalignment that shortens motor and bearing life. At this price, OEM is the obvious choice.

Install Difficulty

Easy to Moderate. With power disconnected, remove the fan guard/panel, support the motor, swap the mount arm, and re-torque the hardware. Basic hand tools and care to keep blade clearance even are all that's required.

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