What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WAHMS1931P4ABA — 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 WAHMS1931P4ABA — 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 9 x 6 inch Blower Wheel is a genuine OEM squirrel-cage wheel for the WAHMS1931P4ABA air handler. The forward-curved wheel mounts to the blower motor shaft and moves conditioned air through the system. It is factory-balanced to deliver rated airflow (CFM) with minimal vibration and noise.

A cracked, dirty, or out-of-balance wheel causes vibration, reduced airflow, and premature motor and bearing wear. Installing the correct OEM wheel restores smooth, quiet, full-capacity operation.
