The Goodman B1392143 is a genuine OEM motor mount grommet for Goodman WPC4349AHAA systems. This small rubber isolation grommet cushions the fan or blower motor where it bolts to its bracket, absorbing vibration and preventing metal-to-metal contact. Hardened, cracked, or missing grommets let the motor transmit vibration into the cabinet — producing a buzzing or rattling noise and accelerating wear on the mount and motor bearings. Replacing the full set of grommets is an inexpensive way to quiet a noisy unit and protect the motor.

Specifications

OEM Part Number: B1392143
Material: Vibration-dampening rubber
Function: Motor mount isolation grommet
Brand: Goodman (genuine OEM)
Compatibility: WPC4349AHAA and select Goodman/Amana units

OEM vs. Generic

The genuine Goodman OEM grommet is molded to the exact bore and shoulder dimensions of your motor bracket, so it seats securely and isolates properly. Generic rubber grommets often differ slightly in thickness or hole size, allowing the motor to shift or the grommet to back out over time. At this price, the OEM part is the obvious choice for a correct fit.

Install Difficulty

Easy (1 of 5). Press the old grommet out of the bracket and seat the new one in its place; on most units it is best to replace all grommets at once while the motor is loosened. Disconnect power before servicing. Tip: buy one per mounting point.
