What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model ACVM970803BNBA — B1376857 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 ACVM970803BNBA — B1376857.

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 genuine Goodman B1376857 Motor Mount Arm secures the blower motor inside your ACVM970803BNBA furnace, holding it in precise alignment with the blower wheel and housing. These mount arms (or legs) attach the motor to the blower belly band and absorb vibration during operation. A bent, cracked, or corroded mount arm can cause excessive noise, wheel rub, or premature motor bearing wear.

Specifications

Part Number: B1376857 (OEM Goodman)
Type: Blower motor mount arm / bracket
Fits: Goodman ACVM970803BNBA and compatible furnace blower assemblies
Function: Mounts and aligns the blower motor; dampens vibration
Construction: OEM-grade steel mounting arm

OEM vs. Generic

The OEM B1376857 matches the factory belly-band hole pattern and arm length, ensuring the motor sits centered in the blower housing. Generic or universal mount arms often require drilling or shimming and can throw off motor alignment. For vibration-critical blower components, OEM delivers the correct fit.

Installation Difficulty

Moderate (3/5). The blower assembly typically must be pulled to access the mount arms. Disconnect power, slide out the blower, transfer the motor to the new arm with the existing hardware, maintaining equal spacing, then reinstall. Plan 45–60 minutes; verify the wheel spins freely before power-up.
