What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WAHMS3743P4ACA — D6723311S 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 WAHMS3743P4ACA — D6723311S.

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 blower wheel 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 D6723311S 11 x 10 inch Blower Wheel is a genuine OEM squirrel-cage wheel built for the WAHMS3743P4ACA air handler and compatible Goodman/Amana units. The blower wheel is the heart of the air handler's airflow — a worn, cracked, or out-of-balance wheel causes weak airflow, rattling, and premature motor failure. This factory wheel restores rated CFM and quiet operation.

Specifications

OEM Part Number: D6723311S
Wheel Size: 11 in diameter x 10 in width
Type: Forward-curved centrifugal (squirrel cage)
Equipment: Air Handler
Compatible Model: WAHMS3743P4ACA
Brand: Goodman (genuine OEM)

OEM vs. Generic

The OEM D6723311S is dynamically balanced and dimensionally matched to the original housing and motor shaft, preventing vibration that destroys bearings. Generic wheels may differ in blade pitch or bore size, reducing airflow and introducing noise. Because the wheel directly loads the blower motor, an out-of-spec replacement shortens motor life — making OEM the cost-effective long-term choice.

Installation Difficulty

Moderate (3/5). Requires disconnecting power, removing the blower assembly, loosening the set screw on the motor shaft, and transferring the wheel with correct shaft depth and set-screw seating on the flat. Verify rotation direction and re-balance fit before reassembly. Professional installation is recommended.
