What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WGPH4549AMAB — 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 WGPH4549AMAB — 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 bracket that supports the condenser fan motor inside the WGPH4549AMAB packaged gas/electric air conditioner. The mount arm holds the fan motor in correct position over the condenser coil, keeping the blade centered in the orifice and free of vibration. Over time these arms can fatigue, bend, or rust — leading to motor wobble, blade rub, and excess noise. Replacing the arm with the factory part restores proper alignment and protects the motor and blade.

Specifications

OEM Part Number: B1376857
Brand: Goodman
Component: Condenser fan motor mount arm / bracket
Fits Model: WGPH4549AMAB packaged unit
Material: Coated/galvanized steel
Mounting: Factory hole pattern — direct fit

OEM vs. Generic

The OEM Goodman mount arm matches the original length, bend geometry, and bolt spacing, so the motor sits at the correct height and the blade stays centered. Universal brackets often require field bending or re-drilling to position the motor, which risks misalignment and vibration. For a low-cost structural part, OEM fit saves time and avoids rework.

Installation Difficulty

Easy to Moderate — disconnect power, support the fan motor, unbolt the old arm, install the new arm, and re-mount the motor. About 20–30 minutes with basic hand tools. No refrigerant or wiring changes required, though motor alignment should be checked before restart.

My AC fan isn’t spinning. What part do I need?

Is this motor mount 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.

Should I use OEM or aftermarket for my Goodman motor mount?

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.
