What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model AMS80905CNA Furnace — 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 AMS80905CNA Furnace — 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 Grommet

The Goodman B1392143 Motor Grommet is a genuine OEM vibration-isolating grommet built for the AMS80905CNA furnace and compatible Goodman and Amana models. These rubber grommets cushion the blower-motor mounting arms where they seat into the motor belly band or mount bracket, absorbing vibration and dramatically reducing operating noise. Dried, cracked, or missing grommets are one of the most common causes of a furnace that hums, buzzes, or rattles — replacing the full set restores quiet, stable motor operation.

Specifications

OEM Part Number: B1392143
Part Type: Blower-motor vibration grommet
Material: Heat-resistant EPDM rubber
Function: Isolates motor vibration & noise
Compatibility: Goodman / Amana AMS80905CNA and related furnaces
Sold as: Individual grommet (replace as a full set for best results)

OEM vs. Generic

Factory-original grommets are molded to the exact inner/outer diameter of the Goodman motor mount and rated for the temperatures inside a furnace cabinet. Generic rubber often runs oversized or undersized, allowing the motor to shift or transmitting vibration straight to the cabinet. OEM ensures a tight, quiet, long-lasting fit.

Installation Difficulty

Easy to Moderate. About 15–20 minutes. Requires pulling the blower assembly to access the motor mount, but no special tools beyond a nut driver. Confident DIYers can handle it; otherwise a quick service call.

How do I replace the motor grommet on my Goodman AMS80905CNA Furnace — 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 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.
