What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WAHMS3636P4ACA — 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 WAHMS3636P4ACA — 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.

The Goodman 0131M00849SP Blower Motor is the genuine OEM indoor blower motor for the WAHMS3636P4ACA air handler and compatible Goodman/Amana units. When the blower hums but won't spin, overheats and trips on thermal limit, or fails to start, the motor is the most common culprit. This factory-matched replacement restores rated airflow and quiet, efficient operation.

Specifications

OEM direct-drive indoor blower motor
Factory-matched bearings, shaft, and mounting for the WAHMS3636P4ACA housing
Thermally protected for safe operation
Paired to the original blower wheel and control wiring
OEM Part Number: 0131M00849SP

OEM vs. Generic

The OEM motor matches the exact horsepower, rotation, shaft size, and mounting pattern of your air handler, so it bolts in and wires up without adapters or recalibration. Universal motors often need new brackets, capacitor matching, and speed-tap rewiring — and a mismatch can under- or over-drive the wheel. For correct airflow and warranty peace of mind, choose the genuine part.

Install Difficulty

Advanced (4/5). Requires pulling the blower assembly, transferring the wheel and bracket, and reconnecting motor leads/capacitor correctly. Plan 60–90 minutes. Disconnect power at the breaker and verify wiring against the unit diagram. Professional installation is recommended.

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.

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.

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

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.
