What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WAHMS3030P4ACA — 0131M00849SP 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 WAHMS3030P4ACA — 0131M00849SP.

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 motor 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.

OEM vs. Generic

This factory Goodman motor matches the original horsepower, voltage, RPM, rotation, shaft diameter, and mounting pattern, so it bolts in and wires up exactly as designed. Universal replacement motors require adapting mounts, re-pinning capacitors, and verifying rotation, and an incorrect spec can overload the wheel or under-deliver CFM. OEM ensures rated performance and preserves warranty coverage.

Compatibility

Engineered for the Goodman WAHMS3030P4ACA air handler. Confirm HP, voltage, shaft size, rotation, and capacitor rating against your existing motor before ordering.

Installation Difficulty: Advanced

Involves removing the blower assembly, transferring the wheel and mounting band, wiring the motor leads and run capacitor correctly, and setting wheel depth and rotation. Plan for 1–2 hours. Disconnect power at the breaker, discharge the capacitor, and label all leads. If you are not comfortable with line-voltage wiring, hire a licensed HVAC technician.

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