What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model ARPF37431BA — 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 ARPF37431BA — 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 support leg that ties the blower motor mount band to the air handler housing in the Goodman ARPF37431BA. The arms hold the motor centered in the blower housing; a bent or broken arm lets the motor sag, throwing the blower wheel out of balance and causing rattle, hum, and premature bearing failure. This factory arm restores proper alignment and rigid support.

Specifications

Part Number: B1376853
Type: Blower motor mount arm
Brand: Goodman (Genuine OEM)
Fits: ARPF37431BA air handler
Equipment: Air Handler
Function: Connects motor mount band to blower housing

OEM vs. Generic

The genuine Goodman OEM arm has the correct length, offset, and bolt-hole spacing to keep the motor concentric in the housing. Generic arms force you to slot holes or bend tabs, which compromises alignment and lets vibration creep back in. Use with mount band B1376851 for the full factory mounting set.

Install Difficulty

Moderate — Best done with the blower assembly out for access. Plan 30–45 minutes. Cut power before service, install arms in matched sets, and torque hardware evenly so the motor sits centered.
