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 Goodman B1392143 Motor Mount Grommet is a genuine OEM rubber vibration isolator used to mount the condenser fan motor on the Goodman/Amana WPH4324AMAB packaged unit. These small but critical grommets cushion the motor against its bracket, absorbing vibration, reducing operating noise, and preventing metal-to-metal fatigue that can crack the mounting bracket or loosen hardware over time.

Rubber grommets dry out, harden, and split after years of heat and UV exposure. Worn grommets are a common cause of a noisy, buzzing, or rattling outdoor unit. Replacing them is one of the cheapest ways to restore quiet, stable fan operation.

Specifications

OEM Part Number: B1392143
Component: Fan motor mount grommet / vibration isolator
Material: Molded EPDM rubber
Fits: Goodman & Amana WPH4324AMAB condenser fan motor mount
Sold individually — order the quantity your bracket requires (typically 3–4 per motor)

OEM vs. Generic

The OEM grommet is molded to the exact bore, shoulder, and durometer of your motor bracket, so it seats securely and dampens vibration as designed. Generic grommets that are too soft or the wrong diameter can allow the motor to sag or shift, throwing the fan blade out of balance.

Installation Difficulty: Easy (DIY-Friendly)

Disconnect power, support the fan motor, remove the mounting bolts, slip out the old grommets, press the new ones into place, and reassemble. No special tools required. Replace all grommets as a set for balanced support.

Frequently Asked Questions

Does this Motor Mount Grommet fit my Goodman WPH4324AMAB — B1392143?

Yes. This is the factory-specified OEM motor mount grommet for the Goodman WPH4324AMAB — 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 WPH4324AMAB — 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.
