What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WPH4330AMAB — 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 WPH4330AMAB — 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.

Goodman B1392143 Motor Mounting Grommet

The Goodman B1392143 is a genuine OEM rubber motor-mount grommet used to secure and cushion the fan motor on the Goodman/Amana WPH4330AMAB packaged unit. These small vibration-isolating grommets sit between the motor mounting legs (or belly-band bracket) and the cabinet, absorbing motor vibration so it isn't transmitted to the sheet-metal housing. Worn, cracked, or missing grommets are one of the most common causes of a noisy, rattling, or humming outdoor unit — and letting the motor run on hardened or missing grommets accelerates bearing wear.

Specifications

Part Number: B1392143
Material: Molded EPDM/rubber vibration isolator
Function: Motor mount cushioning and noise dampening
Fits: WPH4330AMAB and compatible Goodman/Amana motor mounts
Sold as: Single grommet

OEM vs. Generic

The genuine OEM grommet is molded to the exact bore, thickness, and durometer (rubber hardness) Goodman specifies. Generic grommets that are too soft compress and let the motor sag; too hard and they transmit vibration and crack early. OEM ensures the correct fit and long service life. Tip: replace all grommets on the motor as a set for even support.

Install Difficulty: Easy

Rated Easy (1/5). Disconnect power, loosen the motor mount hardware, slip the old grommet out and the new one in, and retorque. A quick, inexpensive repair that restores quiet operation — usually under 15 minutes.

Frequently Asked Questions

Does this Motor Grommet fit my Goodman WPH4330AMAB — B1392143?

Yes. This is the factory-specified OEM motor grommet for the Goodman WPH4330AMAB — 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 grommet on my Goodman WPH4330AMAB — 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 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 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.
