What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WPC4324AHAA — B1368042S 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 WPC4324AHAA — B1368042S.

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 B1368042S is a genuine OEM 9 x 6 inch blower wheel (squirrel cage) built for WPC4324AHAA air conditioning systems. The blower wheel mounts on the motor shaft and moves conditioned air across the coil and through the duct system. This wheel is factory-balanced to the exact weight and blade pitch of the original, so it spins true and delivers rated CFM without the vibration or noise that comes from a mismatched replacement.

Specifications

Wheel Size: 9 inch diameter x 6 inch width
OEM Part Number: B1368042S
Compatible Model: WPC4324AHAA
Brand: Goodman
Type: Forward-curved centrifugal (squirrel cage)
Bore: OEM motor-shaft fit

OEM vs. Generic

The genuine OEM wheel arrives pre-balanced and dimensionally matched to the housing and shaft. Generic 9x6 wheels can vary in bore size, hub depth, and blade count, which causes shaft slippage, imbalance, and reduced airflow. The OEM part protects the motor bearings and keeps the system at its designed efficiency.

Installation Difficulty

Moderate (3/5). Disconnect power, remove the blower assembly, loosen the hub set screw, slide off the old wheel, and align the new wheel's set screw to the shaft flat. Confirm clearance inside the housing before re-energizing. Plan for 30–60 minutes.
