What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WAHMS4860P4ABA — B1376863 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 WAHMS4860P4ABA — B1376863.

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 genuine Goodman B1376863 Motor Mount is the factory blower motor support bracket for WAHMS4860P4ABA air handlers. This bracket secures the blower motor to the air handler housing, holding the motor in proper alignment so the blower wheel spins true and the system moves air quietly and efficiently. A cracked, rusted, or vibration-fatigued mount causes noise, wobble, and premature motor bearing failure — replacing it with the correct OEM part restores quiet, stable operation.

OEM vs. Generic

This is a genuine Goodman OEM component built to exact factory dimensions and mounting-hole spacing, guaranteeing a drop-in fit. Aftermarket brackets often differ slightly in bolt pattern or band diameter, forcing field modification and risking motor misalignment. For a vibration-critical part like a motor mount, OEM is the reliable choice.

Installation Difficulty

Easy (2/5). A basic repair for an HVAC technician — disconnect power, unbolt the blower assembly, transfer the motor to the new mount, and reinstall. Typically 20–40 minutes. Always shut off power at the breaker before servicing.
