What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model WPH4342AHAB — 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 WPH4342AHAB — 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 Motor Mount Grommet is a genuine OEM rubber isolator designed for the WPH4342AHAB packaged unit and compatible Goodman/Amana equipment. This small but critical component cushions the fan motor against the mounting bracket, absorbing vibration and preventing the metallic rattle and premature bearing wear that occur when grommets crack, harden, or fall out with age.

Specifications

OEM Part Number: B1392143
Type: Motor mount grommet / vibration isolator
Material: Molded EPDM rubber
Fits: Goodman WPH4342AHAB and select packaged units
Brand: Goodman (OEM)

OEM vs. Generic

This is the exact factory grommet, molded to the correct durometer and dimensions for a snug, rattle-free fit. Generic aftermarket grommets are often the wrong thickness or hardness, allowing motor movement that transmits noise and stresses the motor shaft. For a component this inexpensive, OEM is the smart choice.

Installation Difficulty

Easy (DIY-friendly). No special tools required — simply de-energize the unit, slip the old grommet off the mount, and press the new one into place. Replace all grommets as a set for balanced motor support. Always shut off power at the disconnect before servicing.

Order the genuine Goodman B1392143 to keep your blower or condenser motor quiet, aligned, and properly isolated.

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.
