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.

OEM vs. Generic

This genuine Goodman motor matches the original RPM, rotation, shaft diameter, voltage, and mounting pattern for a true drop-in fit. Generic replacements often require adapting brackets or capacitor changes and may not match the original airflow specification. OEM delivers correct performance and easier installation.

Install Difficulty

Moderate. Requires disconnecting power, removing the fan grille and blade, matching wiring to the correct capacitor terminals, and confirming shaft depth and rotation. Always verify the run capacitor rating and replace it if suspect. Professional installation is recommended for those unfamiliar with motor wiring.

Disconnect power and discharge the capacitor before servicing.

Frequently Asked Questions

Does this Condenser Fan Motor fit my Goodman GMT070-3 — B13400251S?

Yes. This is the factory-specified OEM condenser fan motor for the Goodman GMT070-3 — 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 GMT070-3 — 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.
