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.

Goodman B1376857 Fan Motor Mount Arm

The Goodman B1376857 is a genuine OEM condenser fan motor mount arm (bracket leg) for the WGPH4530AMAB packaged unit. These bracket arms support the condenser fan motor and bolt to the fan grille or top panel, holding the motor centered in the airflow. Over years of vibration and weather exposure, mount arms can crack, rust through, or bend — causing a noisy, wobbling fan. Replacing the arm is an inexpensive way to restore solid motor support and prevent further damage.

Specifications

Part type: Fan motor mount arm / bracket leg
OEM part number: B1376857
Brand: Goodman (genuine OEM)
Primary fit: WGPH4530AMAB
Function: Condenser fan motor support / mounting
Mounting: Bolt-on (typically used in a set of arms)

OEM vs. Generic

The OEM arm matches the exact length, bend angle, and hole pattern needed to position the motor correctly over the coil. Generic or fabricated brackets risk misaligning the fan blade in the orifice, causing vibration, rubbing, and premature motor bearing wear. The factory part drops in with no fitment guesswork.

Installation Difficulty

Easy / DIY-friendly. Disconnect power, support the fan motor, unbolt the damaged arm, fit the new B1376857, and torque the hardware. Basic hand tools and roughly 15–20 minutes. If replacing one cracked arm, inspect the remaining arms for fatigue while you are in there.

Frequently Asked Questions

Does this Motor Mount Bracket fit my Goodman WGPH4530AMAB — B1376857?

Yes. This is the factory-specified OEM motor mount bracket for the Goodman WGPH4530AMAB — B1376857. 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 motor mount bracket on my Goodman WGPH4530AMAB — B1376857?

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 motor mount bracket 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 motor mount bracket?

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.
