What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WPC4324AHAB — B1392143 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 WPC4324AHAB — B1392143.

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 grommet 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 B1392143 is a genuine OEM motor mount grommet for the WPC4324AHAB packaged air conditioner. This rubber isolator cushions the fan motor against its mounting bracket, dampening vibration and reducing operating noise while preventing metal-to-metal wear. Hardened, cracked, or missing grommets are a common source of buzzing, rattling, and loosened motor mounts — an inexpensive part that protects a costly motor.

Specifications

Material: Vibration-dampening rubber
Application: Fan motor mount isolator / grommet
OEM Part Number: B1392143
Fits: Goodman WPC4324AHAB and compatible packaged AC models
Type: OEM Goodman direct-replacement grommet

OEM vs. Generic

The OEM Goodman grommet matches the exact inside/outside diameter and durometer (rubber hardness) needed to seat in the factory bracket and isolate motor vibration correctly. Ill-fitting generic grommets can be too soft or too stiff, allowing motor sag or transmitting noise. At this price point, OEM is the obvious choice. We recommend replacing all isolators as a set.

Installation

Difficulty: Easy (1/5). Disconnect power, support the motor, push the old grommet out of the bracket leg, and press the new grommet into place. Repeat for each mount point. Takes only a few minutes with no special tools.

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.

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