What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WPC4336AHAA — B1368036S 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 — B1368036S.

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 wheel 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 B1368036S 9 x 8 in. Blower Wheel

The Goodman B1368036S is a genuine OEM 9 x 8 inch squirrel-cage blower wheel for the Goodman/Amana WPC4336AHAA packaged air conditioner. Mounted on the blower motor shaft, this wheel is what physically moves air across the indoor coil and through your ductwork. A cracked hub, bent or broken fins, accumulated debris, or an out-of-balance wheel will cause vibration, reduced airflow, rattling noise, and added strain on the blower motor bearings. A factory-balanced OEM wheel restores smooth, rated airflow and protects the motor you paired it with.

Specifications

OEM Part Number: B1368036S
Dimensions: 9 in. diameter x 8 in. width
Type: Forward-curved squirrel-cage blower wheel
Application: Indoor blower assembly
Compatible Model: WPC4336AHAA
Brand: Goodman (fits Amana equivalents)

OEM vs. Generic

The OEM B1368036S matches the exact diameter, width, bore size, rotation, and fin profile the WPC4336AHAA blower housing was designed for, and it ships factory-balanced. Generic wheels can differ in bore or width, requiring bushings or trimming, and an unbalanced or mismatched wheel transmits vibration straight into the motor bearings, shortening motor life. Matching the OEM wheel to the OEM motor is the reliable choice.

Installation Difficulty

Rating: Moderate. Disconnect power, slide the blower assembly out, loosen the setscrew on the hub, pull the old wheel, fit the new wheel to the correct depth on the shaft, align it in the housing, and torque the setscrew on the shaft flat. Allow 30–45 minutes; verify the wheel spins freely without rubbing before restoring power.

Step 1: Turn off breaker. Step 2: Note motor specs: HP, RPM, voltage, rotation direction. Step 3: Remove old motor from mounting. Step 4: Transfer fan blade to new motor. Step 5: Mount new motor, reconnect wiring. Step 6: Restore power, verify rotation direction.

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 wheel 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 wheel?

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.
