What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WPC4336AHAA — 11091202S 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 WPC4336AHAA — 11091202S.

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.

Goodman 11091202S Blower Motor

The Goodman 11091202S is a genuine OEM indoor blower motor built for the Goodman/Amana WPC4336AHAA packaged air conditioner. This motor drives the blower wheel that circulates conditioned air through your ductwork, so it is one of the most important moving parts in the system. Symptoms of a failing blower motor include weak or no airflow at the registers, overheating and thermal cutout, loud bearing noise, or a motor that hums but won't spin. Replacing it with the factory-matched OEM motor restores rated CFM, correct rotation, and quiet operation.

Specifications

OEM Part Number: 11091202S
Horsepower: 1/4 HP (factory-rated for this chassis)
Type: Direct-drive indoor blower motor
Application: Air handling / blower section
Compatible Model: WPC4336AHAA
Brand: Goodman (fits Amana equivalents)

OEM vs. Generic

The OEM 11091202S arrives with the exact horsepower, RPM, voltage, rotation, shaft diameter, and mounting configuration the WPC4336AHAA was engineered around — paired correctly with the matching blower wheel for rated airflow. Generic replacement motors often require new mounting brackets, shaft adapters, or rewiring, and a mismatch in speed or torque can under- or over-drive the wheel, hurting comfort and efficiency. For a primary airflow component, OEM is strongly recommended.

Installation Difficulty

Rating: Moderate to Advanced. Disconnect power, remove the blower assembly, transfer the wheel and set the correct hub spacing, label and reconnect wiring per the diagram, and verify rotation direction. Plan on 45–90 minutes. We recommend a licensed HVAC technician for this repair.

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 motor 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 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.
