What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WAHMS1931P4ACA — 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 WAHMS1931P4ACA — 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 Blower Wheel is a genuine OEM 9 x 6 inch fan wheel engineered as a direct-fit replacement for Goodman/Amana WAHMS1931P4ACA air handlers. The blower wheel is the heart of your air handler's airflow system — it pulls conditioned air across the coil and pushes it through your duct system. A cracked, warped, or out-of-balance wheel causes weak airflow, vibration, rattling, and uneven room temperatures, so replacing it with a precision-balanced OEM wheel restores quiet, efficient operation.

Specifications

Wheel diameter x width: 9 in. x 6 in.
OEM Part Number: B1368042S
Brand: Goodman (Amana compatible)
Equipment: Air Handler
Fits Model: WAHMS1931P4ACA
Material: Galvanized steel, factory-balanced

OEM vs. Generic

This is the genuine OEM B1368042S. Because blower wheels are dimensionally and rotationally matched to the housing and motor shaft, an OEM wheel guarantees correct bore size, balance, and CFM output. Aftermarket wheels are rare for this size and often arrive unbalanced, leading to premature motor-bearing wear. We recommend OEM for blower-wheel replacements.

Installation Difficulty

Moderate (3/5). Requires removing the blower assembly, loosening the set screw on the motor shaft, and re-seating the new wheel flush with the shaft. Always disconnect power first. Most experienced DIYers complete this in 45–60 minutes; if you are unsure, a licensed HVAC technician can install it quickly.

My AC fan isn’t spinning. What part do I need?

Should I use OEM or aftermarket for my Goodman blower wheel?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
