What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WAHMS3642P4ABA — B1368016S 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 WAHMS3642P4ABA — B1368016S.

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 B1368016S Blower Wheel is a genuine OEM 10 x 8 inch forward-curved squirrel-cage wheel for WAHMS3642P4ABA air handlers. It moves conditioned air across the coil and into the duct system, and a correctly balanced wheel is essential for rated CFM, quiet operation, and proper temperature split.

Each wheel is precision-balanced to minimize vibration and bearing wear, with a sized hub bore that locks securely to the blower motor shaft. A cracked, dirt-loaded, or out-of-balance wheel causes low airflow, noise, and premature motor failure — replacing it with the exact OEM wheel restores factory performance and protects the motor.

Specifications

Component: Forward-curved blower (squirrel-cage) wheel
Dimensions: 10 in. diameter x 8 in. width
Fits: Goodman WAHMS3642P4ABA air handler
Material: Galvanized steel, factory-balanced
Mounting: Set-screw hub to motor shaft
OEM Part Number: B1368016S

OEM vs. Generic

The OEM wheel matches the factory diameter, width, blade pitch, and bore for rated CFM and balance out of the box. A Generic wheel may approximate the size but mismatched blade geometry or balance can reduce airflow and shorten motor life.

Installation Difficulty

Moderate (3/5) — Requires pulling the blower assembly, loosening the hub set screw, and aligning the wheel on the shaft to spec. Mark shaft depth and set-screw orientation before removal; verify free rotation and no housing rub on reassembly.

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

Fan not spinning, spinning slowly, or making grinding/squealing noises = motor failure. Grinding = bearings failed. Squealing = bearings dry. No spin + hum = check the motor capacitor first before replacing the entire motor.

Is this blower wheel compatible with Bryant or Payne too?

Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

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.
