What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model GMPH075-4 — B13400251S is this exact part. It is the factory-specified replacement with exact OEM specifications.

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.

Keep your system moving air with the genuine Goodman B13400251S 1/6 HP condenser fan motor, a direct OEM replacement for the GMPH075-4 and compatible Goodman/Amana units. When the outdoor fan stops turning or runs hot, head pressures climb and the compressor risks a high-pressure trip — this factory-spec motor restores correct airflow and protects the rest of the system.

Specifications

Horsepower: 1/6 HP
Voltage: 208/230V
Motor type: PSC condenser fan motor
Bearings: Sealed ball bearing for long life
OEM Part Number: B13400251S
Fits: Goodman GMPH075-4

OEM vs. Generic

The genuine OEM B13400251S matches the original RPM, rotation, shaft diameter, and mounting so it drops straight in with no bracket modification. Universal generics often require re-clocking the mount, guessing at capacitor sizing, and adapting the shaft — adding labor and risking premature failure. OEM keeps warranty coverage intact.

Installation Difficulty

Moderate (3/5) — Plan for 45–60 minutes. Disconnect power at the breaker, discharge the run capacitor, note the wiring colors, transfer the fan blade and mounting hardware, then wire and mount the new motor. A multimeter and basic HVAC experience are recommended; confirm the matching run capacitor is in spec while you have the unit open.

Frequently Asked Questions

Does this Condenser Fan Motor fit my Goodman GMPH075-4 — B13400251S?

Yes. This is the factory-specified OEM condenser fan motor for the Goodman GMPH075-4 — 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 GMPH075-4 — 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.
