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

Restore full airflow to your GMT090-4 system with the genuine Goodman B13400252S condenser fan motor. This 1/6 HP motor spins the outdoor fan blade that pulls air across the condenser coil, rejecting heat during the cooling cycle. A failing motor shows up as a hot-running unit, tripped breakers, humming without rotation, or a fan that won't start — all signs the bearings or windings have worn out.

Specifications

Genuine Goodman OEM part number: B13400252S
Horsepower: 1/6 HP
Application: condenser fan motor for GMT090-4
Sealed ball/sleeve bearings for quiet, long-life operation
Factory-matched shaft diameter and mounting pattern
Designed for continuous outdoor duty and weather exposure

OEM vs. Generic

The OEM B13400252S arrives with the exact horsepower, RPM, rotation, voltage, and shaft dimensions your unit was built for — drop it in and it fits. Universal replacement motors save money up front but require matching capacitor sizing, re-drilling mounts, and adapting the shaft, and a mismatched RPM can overload the compressor or under-cool the home. OEM removes the guesswork and protects system efficiency.

Installation Difficulty

Moderate to advanced. Requires discharging and matching the run capacitor, transferring the fan blade with correct blade-to-motor clearance, and confirming wiring polarity for rotation direction. Budget 45–90 minutes. If you are not comfortable working around a charged capacitor, hire a licensed HVAC technician.

Disconnect power at the outdoor disconnect and discharge the capacitor before servicing. Confirm the part number on your rating plate.

Frequently Asked Questions

Does this Condenser Fan Motor fit my Goodman GMT090-4 — B13400252S?

Yes. This is the factory-specified OEM condenser fan motor for the Goodman GMT090-4 — 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 GMT090-4 — 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.
