What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model GPC1324H21A — 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 GPC1324H21A — 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 Grommet is the genuine OEM rubber isolation grommet used at the fan-motor mount on your Goodman GPC1324H21A packaged air conditioner. This small but important part cushions the motor against the mounting bracket, absorbing vibration and preventing it from transferring into the cabinet. Dried-out, cracked, or missing grommets are a common source of buzzing and rattling noises and can accelerate motor bracket fatigue.

Specifications

OEM Part Number: B1392143
Function: Fan-motor mount vibration isolator
Material: Molded rubber
Brand: Goodman
Fits Model: GPC1324H21A
Sold: Each (replace as a full set for best results)

OEM vs. Generic

The OEM grommet is molded to the exact diameter and shoulder thickness Goodman specifies, so it seats firmly and dampens vibration as designed. Generic grommets in the wrong durometer or size can compress unevenly or fall out, letting the motor buzz. At this price, there is little reason not to use the genuine part — and replacing all mount grommets at once gives the quietest result.

Installation Difficulty

Easy. Slip the old grommet off and press the new one into the mount band — no tools or wiring required, typically under 10 minutes. Disconnect power before reaching into the unit. An ideal low-cost DIY repair to do alongside a motor replacement.

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.
