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.

The genuine Goodman B1392143 Motor Grommet is an OEM rubber mounting bushing that isolates the condenser fan motor from the mounting bracket on the WPH4324AHAB packaged unit and compatible Goodman/Amana equipment. These grommets absorb motor vibration, reduce operating noise, and prevent fatigue cracking of the motor mount and sheet-metal bracket over years of service.

Specifications

Part type: Fan motor mounting grommet / isolator
Material: EPDM/rubber vibration-damping compound
Function: Motor vibration isolation and noise reduction
Sold as: Individual grommet (order the set your motor requires)
Fits: Goodman WPH4324AHAB and compatible models
Brand: Goodman (OEM)

OEM vs. Generic

The OEM B1392143 is molded to the correct inner/outer diameter and durometer so the motor seats securely without excess play. Generic grommets that are too soft or the wrong size allow the motor to shift, causing fan-blade contact, noise, and premature motor-bearing wear. At this price point, using OEM is the obvious choice.

Installation Difficulty

Easy — Disconnect power, support the fan motor, remove the mounting hardware, replace the grommets, and reassemble. Basic hand tools only; a straightforward DIY task. Replace all grommets as a set for even support.

Frequently Asked Questions

Does this Motor Mount Grommet fit my Goodman WPH4324AHAB — B1392143?

Yes. This is the factory-specified OEM motor mount grommet for the Goodman WPH4324AHAB — B1392143. 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 grommet on my Goodman WPH4324AHAB — B1392143?

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 grommet 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 grommet?

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.
