What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model GMT045-3A — B1368034S 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 GMT045-3A — B1368034S.

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 B1368034S 10 x 6 in. Blower Wheel

The Goodman B1368034S is a genuine OEM 10 x 6 inch squirrel-cage blower wheel built as an exact-fit replacement for the Goodman GMT045-3A gas furnace. The blower wheel mounts on the motor shaft and pulls air through the heat exchanger, delivering conditioned air to your home. A wheel that is cracked, clogged with debris, or out of balance causes vibration, noise, and weak airflow. A fresh, factory-balanced wheel restores smooth, efficient air delivery.

Specifications

Part Number: B1368034S (OEM Goodman)
Wheel Size: 10 x 6 in. (diameter x width)
Type: Forward-curved squirrel-cage blower wheel
Fits Model: GMT045-3A furnace
Brand: Goodman / Amana
Balance: Factory pre-balanced

OEM vs. Generic

The OEM B1368034S guarantees the correct bore, hub position, and rotation for the GMT045-3A, so it seats and balances correctly on the existing motor. Generic 10 x 6 wheels are more affordable but require verifying bore diameter and rotation direction, and may need re-balancing. Choose OEM for a guaranteed match; choose generic to reduce cost when you can confirm the fit.

Installation Difficulty: Moderate

Requires removing the blower assembly, loosening the set screw, and sliding the wheel off the shaft. Mark hub-to-shaft depth and rotation before removal so the new wheel seats identically. Plan 45–60 minutes. Disconnect power at the furnace switch and breaker before servicing.

Compatible with Goodman GMT045-3A. Verify your existing wheel dimensions and bore before ordering.

Yes. This is the factory-specified OEM blower wheel for the Goodman GMT045-3A — B1368034S. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the blower wheel on my Goodman GMT045-3A — B1368034S?

Difficulty: Medium-Hard (1–2 hrs)
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.
