What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WAHMS3743P4ABA Air Handler — 0271A00013S 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 WAHMS3743P4ABA Air Handler — 0271A00013S.

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 housing 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 0271A00013S Blower Housing is a genuine OEM scroll housing for the WAHMS3743P4ABA air handler. It surrounds the blower wheel and directs conditioned air into the supply duct at the engineered velocity and pressure. A cracked, corroded, or deformed housing causes air leaks, excess noise, and reduced CFM — replacing it restores rated airflow and quiet, efficient operation across heating and cooling modes.

Type: Blower scroll housing
Brand: Goodman (also fits select Amana air handlers)

OEM vs. Generic

This genuine Goodman housing is dimensionally matched to the original blower wheel and motor mounting points, preserving the factory cutoff geometry and clearance that determine airflow and sound levels. Generic or universal housings rarely match the wheel diameter and mounting pattern, leading to rubbing, vibration, and lost capacity. The OEM part bolts in without rework.

Installation Difficulty

Moderate to Advanced — requires pulling the blower assembly, transferring the wheel and motor, and re-aligning the housing. Best handled by an experienced technician with the unit de-energized. Budget 45–90 minutes.

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 housing compatible with Bryant or Payne too?

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