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 B13400251S 1/6 HP Condenser Fan Motor

The B13400251S is a genuine OEM 1/6 HP condenser fan motor compatible with the Goodman GMPE125-5A and related Goodman/Amana equipment. This outdoor fan motor spins the condenser blade to reject heat from the system. A motor that hums, runs hot, cycles on thermal overload, or won't start is a leading cause of high head pressure, tripped breakers, and no-cooling calls — replacing it restores full condenser airflow.

Specifications

Part number: B13400251S
Horsepower: 1/6 HP
Type: Condenser / outdoor PSC fan motor
Application: Drives condenser fan blade for heat rejection
Fits: Goodman GMPE125-5A and related Goodman/Amana units

Verify voltage, RPM, rotation, and run-capacitor rating against your old motor's nameplate before installing.

OEM vs. Generic

This genuine OEM Goodman motor matches the factory HP, shaft, mounting, and electrical spec for a true drop-in fit. Universal replacements can work but require matching rotation, capacitor, and mounting, plus rewiring — increasing install time and error risk. OEM removes the guesswork and preserves warranty-grade performance.

Install Difficulty: Moderate–Advanced ★★★★☆

Best handled by an experienced DIYer or HVAC technician — about 45–90 minutes and involves line-voltage wiring. Disconnect and lock out power, discharge the run capacitor, note the wiring, transfer the fan blade at the correct shaft height, mount the motor, and wire per the diagram. Replace the run capacitor at the same time and confirm correct rotation on startup.

Frequently Asked Questions

Does this Condenser Fan Motor fit my Goodman GMPE125-5A — B13400251S?

Yes. This is the factory-specified OEM condenser fan motor for the Goodman GMPE125-5A — B13400251S. 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 GMPE125-5A — B13400251S?

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.
