The Goodman B1392143 Motor Mount Grommet is a genuine OEM rubber isolator used to cushion the fan motor in the WPH4342AMAA package unit. Grommets seat between the motor mounting legs or belly-band and the sheet-metal bracket, absorbing motor vibration before it can transmit into the cabinet as noise or fatigue the mounting hardware. Dried, cracked, or missing grommets are a common source of buzzing, rattling, and loosened motor bolts — replacing them is one of the cheapest and most effective fixes for a noisy outdoor unit.

Specifications

OEM Part Number: B1392143
Part Type: Fan motor mounting grommet / vibration isolator
Fits Model: WPH4342AMAA package heat pump
Material: Molded EPDM/neoprene rubber
Function: Vibration dampening and motor isolation
Brand: Goodman OEM replacement

OEM vs. Generic

The OEM grommet is molded to the exact bore, groove depth, and durometer that matches your motor's mounting studs and bracket thickness. Generic grommets that are too soft or the wrong groove size allow the motor to sag or walk, throwing the fan blade off-center. Because the part costs only a couple of dollars, there is little reason not to use the correct OEM piece — and we recommend replacing the full set at the same time.

Installation Difficulty

Difficulty: Easy (DIY). With power disconnected, remove the motor mounting bolt, slip out the old grommet, and press the new one into the bracket. No refrigerant work and no special tools required — typically a 5-minute job per grommet.
