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 Goodman B13400251S is a genuine OEM 1/6 HP condenser fan motor engineered as a direct-fit replacement for the GMPV125-3 package unit. This motor drives the outdoor condenser fan that pulls air across the coil to reject heat — a failed or noisy motor causes high head pressure, poor cooling, and eventual compressor damage. Installing the correct OEM motor restores proper airflow, quiet operation, and full system efficiency.

Specifications

Part Number: B13400251S
Horsepower: 1/6 HP
Type: Condenser fan motor (PSC)
Brand: Goodman (OEM)
Compatible Model: GMPV125-3
Application: Outdoor top-discharge condenser fan

OEM vs. Generic

This genuine Goodman OEM motor is matched to the factory rotation, shaft diameter, mounting pattern, RPM, and electrical ratings, so it drops in without adapters or rewiring. Universal replacement motors often need new mounting brackets, capacitor matching, and blade rework, and can run hotter or louder. OEM guarantees the correct fit and preserves your warranty.

Installation Difficulty

Moderate (3/5). Requires disconnecting power, transferring the fan blade, matching motor leads to the run capacitor, and confirming rotation. Best performed by an experienced technician; always lock out power first.

Frequently Asked Questions

Does this Condenser Fan Motor fit my Goodman GMPV125-3 — B13400251S?

Yes. This is the factory-specified OEM condenser fan motor for the Goodman GMPV125-3 — 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 GMPV125-3 — 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.
