What HP motor do I need for my Goodman unit?

The correct replacement for Goodman model GPC1342H21A — 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 GPC1342H21A — 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 vibration-isolation grommet used to mount the fan motor on the Goodman GPC1342H21A packaged air conditioner. These small but critical isolators cushion the motor against its mounting bracket, dampening vibration and noise while preventing metal-to-metal wear and electrical-ground chatter. Dry-rotted, cracked, or missing grommets let the motor rattle, transmit hum into the cabinet, and shorten bearing life.

OEM vs. Generic

The OEM grommet is molded to the exact inner/outer diameter and durometer of the GPC motor bracket, so it seats snugly and damps vibration as designed. Generic grommets that are too soft or the wrong size let the motor shift or fail to isolate noise. At this price, genuine is always worth it.

Install Difficulty

Easy (1/5). Loosen the motor bracket, press out the old grommet, push the new one into the mounting hole, and re-seat the motor. Plan 5–15 minutes. Disconnect power before working near the fan motor.

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.
