What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WAHMS3743P4ACA — 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 WAHMS3743P4ACA — 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 is a genuine OEM blower housing (scroll) for the WAHMS3743P4ACA air handler. The housing surrounds the blower wheel and directs conditioned air into the supply ductwork. A correctly shaped factory scroll is essential for rated airflow (CFM), low operating noise, and proper static pressure across the coil — a cracked or warped housing leaks air, kills efficiency, and can let the blower wheel rub.

Specifications

Part Number: 0271A00013S
Type: Blower housing / scroll assembly
Application: Goodman / Amana air handlers, model WAHMS3743P4ACA
Function: Houses blower wheel and channels supply airflow
Build: OEM-formed sheet metal with factory mounting points

OEM vs. Generic

Aftermarket housings frequently miss the exact cutout geometry and mount locations of the WAHMS series, forcing drilling, shimming, or wheel-clearance compromises that increase noise and reduce CFM. The OEM 0271A00013S drops into the original brackets with correct wheel clearance and air seal, restoring designed performance.

Installation

Difficulty: Moderate. Requires removing the blower assembly, transferring the motor and wheel, and re-seating the housing — typically 45–90 minutes for an experienced tech. Cut power at the disconnect and verify wheel set-screw alignment before restoring power.

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?

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 housing?

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.
