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.

Goodman B13400252S 1/6 HP Condenser Fan Motor

The Goodman B13400252S is a genuine OEM 1/6 HP condenser fan motor for GMT090-3A series equipment. This motor drives the outdoor fan that pulls air across the condenser coil to reject heat. A failing condenser motor leads to high head pressure, weak or no cooling, compressor overheating, and safety trips. Common failure signs include a fan that hums but won't spin, a fan that spins slowly, or a bearing that is hot and noisy. Installing the correct OEM motor restores proper heat rejection and protects the compressor.

Specifications

Part Number: B13400252S (OEM)
Horsepower: 1/6 HP
Type: Condenser (outdoor) fan motor
Fits: Goodman GMT090-3A
Application: Outdoor condenser fan drive

OEM vs. Generic

The OEM B13400252S matches the factory HP, rotation, shaft, and mounting so it bolts in and wires up without adaptation. Universal motors often need a new capacitor, shaft adapter, and mounting bracket, and mismatched rotation or HP reduces airflow and coil performance. For a precise fit and rated cooling, the OEM motor is the recommended replacement.

Installation Difficulty

Moderate — requires removing the fan grille/blade, mounting the new motor, transferring the blade with correct clearance, and reconnecting leads and the run capacitor. Plan 45–75 minutes. Disconnect power at the disconnect and discharge the capacitor before servicing; professional installation is recommended if you are unsure of the wiring.

Frequently Asked Questions

Does this Condenser Fan Motor fit my Goodman GMT090-3A — B13400252S?

Yes. This is the factory-specified OEM condenser fan motor for the Goodman GMT090-3A — B13400252S. 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 condenser fan motor on my Goodman GMT090-3A — B13400252S?

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 condenser fan 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 condenser fan 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.
