What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WPH4330AMAA — 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 WPH4330AMAA — 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 Mount Grommet

The Goodman B1392143 is a genuine OEM rubber motor mount grommet for the WPH4330AMAA packaged unit. These small isolators cushion the condenser or blower fan motor where it bolts to the mounting bracket. They absorb motor vibration, prevent metal-to-metal contact, and keep the fan assembly quiet and properly aligned. Dried out, cracked, or missing grommets are a common source of buzzing, humming, and premature motor bearing wear.

OEM vs. Generic

This genuine Goodman OEM grommet is molded to the exact inner and outer diameter of the WPH4330AMAA motor mount studs, so it seats snugly without slipping. Generic hardware-store grommets are rarely the right durometer or dimension and can compress unevenly, reintroducing vibration. At this price, the OEM part is the obvious choice.

Installation Difficulty

Easy — DIY friendly. Cut power at the disconnect, loosen the motor mount bolts, slide the old grommet off the stud, and press the new one into place. A few minutes per grommet with basic hand tools. No refrigerant or wiring work required.

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.
