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.

The Goodman B1392143 Motor Mount Grommet is a genuine OEM rubber isolator designed for the WPH4342AMAB package unit and compatible Goodman/Amana models. This small but critical component cushions the fan motor against the mounting bracket, absorbing operating vibration and preventing metal-to-metal contact that leads to rattling, premature bearing wear, and cracked mounts.

Specifications

OEM Part Number: B1392143
Type: Fan motor mounting grommet / vibration isolator
Material: Molded EPDM-grade rubber
Fits: Goodman WPH4342AMAB and select Goodman/Amana package units
Sold individually — most motor mounts use 3 to 4 grommets

OEM vs. Generic

Genuine OEM grommets are molded to the exact durometer and bore diameter specified by Goodman, ensuring the motor sits at the correct alignment and the isolation performs as engineered. Generic rubber substitutes often compress unevenly or degrade quickly under heat, allowing the motor to shift and vibrate. For a part this inexpensive, OEM is always the smart choice.

Installation Difficulty

Easy (DIY-friendly). With power disconnected, remove the motor mount bolt, slide out the worn grommet, and press the new one into place. Typical replacement takes under 10 minutes with basic hand tools. Always inspect all grommets on the mount and replace as a set for even isolation.

Does this Motor Mount Grommet fit my Goodman WPH4342AMAB Package Unit — 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 mount 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 mount 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.
