What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WPH4348AMAB — 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 WPH4348AMAB — 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 Goodman B1376857 Motor Mount Arm is a genuine OEM support bracket engineered for WPH4348AMAB packaged heat pump units. This arm secures the condenser fan motor to the top panel, holding the motor in precise alignment so the fan blade clears the shroud and airflow across the outdoor coil stays balanced. A worn, cracked, or bent mount arm is a common cause of fan wobble, vibration noise, and premature motor bearing failure.

Part Type: Condenser Fan Motor Mount Arm / Bracket
Brand: Goodman
Compatible Model: WPH4348AMAB (packaged heat pump)

OEM vs. Generic

This is a factory OEM Goodman component — it matches original bolt-hole spacing and motor stud pattern exactly, so no drilling or modification is required. Generic universal brackets often require field fabrication and can leave the motor slightly off-axis, which shortens motor life. For a guaranteed drop-in replacement, choose the OEM arm.

Installation Difficulty

Easy (1/5). Disconnect power, remove the fan/motor assembly, swap the old arm for the new one using the existing hardware, and reassemble. Basic hand tools and about 20 minutes are all that is typically needed. Always follow lockout/tagout procedures.
