What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model ADPF30421BA — B1376853 is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Goodman equipment which lists the model number ADPF30421BA — B1376853.

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.

Is this motor mount compatible with Bryant or Payne systems too?

Many Goodman parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

The Goodman B1376853 Motor Mount Arm is a genuine OEM blower motor support bracket engineered for the Goodman ADPF30421BA and compatible air handlers. The mount arms connect the motor support band to the blower housing, suspending the motor securely while dampening vibration. Together they keep the motor shaft perfectly centered to the blower wheel. A bent or fatigued arm lets the motor sag or vibrate, producing noise and uneven airflow.
