What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WAHMS3743P4ABA Air Handler — B1376863 is this exact part. It is the factory-specified replacement with exact OEM specifications.

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 B1376863 Motor Mount is a genuine OEM bracket that secures the blower motor inside the WAHMS3743P4ABA air handler. It holds the motor in precise alignment with the blower wheel and housing while dampening vibration for quiet, balanced operation. A bent, cracked, or worn mount lets the motor shift, causing wheel rub, excess noise, and premature bearing wear — this OEM replacement restores correct positioning and isolation.

Specifications

Part Number: B1376863
Type: Blower motor mount / mounting bracket
Brand: Goodman (also fits select Amana air handlers)
Fits Model: WAHMS3743P4ABA
Equipment: Air Handler
Function: Secures and isolates the blower motor in the housing

OEM vs. Generic

The genuine Goodman mount matches the original bolt pattern, belly-band diameter, and leg geometry so the motor seats at the factory depth and angle. Generic mounts often force shimming or drilling to fit, which can throw off wheel alignment. The OEM part bolts directly to the factory points for a true, vibration-free fit.

Installation Difficulty

Moderate — de-energize the unit, support the motor, transfer it to the new mount, and re-center the wheel in the housing. Common hand tools only. Typically 30–45 minutes.
