Goodman Air conditioner is loud or noisy
If your Goodman air conditioner is loud or noisy, the sound usually points to a worn or loose moving part, but the exact noise matters. A Goodman air conditioner making noise is most often traced to the compressor, which can get louder as it wears, although a noisy compressor may keep running for years and should be replaced by a licensed professional if needed. The next likely cause is a dual shaft fan motor with worn bearings, followed by a damaged fan blade or one rubbing against the housing. If the AC is making loud noise near the outdoor unit, the condenser fan motor may be failing, especially if it has proper voltage and the capacitor checks out. A standard fan motor with worn bearings can also cause air conditioner rattling, grinding, or scraping sounds. If the noise comes from the blower area, check the blower wheel for wobbling, looseness, or a damaged set screw. Enter your Goodman model number on RepairClinic.com to find the exact replacement compressor, fan motor, fan blade, condenser fan motor, or blower wheel that fits your air conditioner.
01 - Goodman Air Conditioner Compressor
When the compressor is wearing out, it generates more noise than usual. When this happens, it is not necessary to replace the compressor—compressors often last for years after they become noisy. However, if you would prefer to have a new compressor, have a licensed professional replace it.

02 - Goodman Air Conditioner Dual Shaft Fan Motor
The fan motor or dual shaft fan motor has bearings which are usually permanently lubricated. However, over several years, the lubrication will break down, causing the motor to become noisy. If this happens, replace the dual shaft fan motor.

03 - Goodman Air Conditioner Fan Blade
Air conditioners have a fan blade in the front and a fan blade in the rear. Check both fan blades for damage. If a fan blade is damaged, or is rubbing against the fan housing, replace it.
Highly Likely
04 - Goodman Air Conditioner Condenser Fan Motor
To determine if the condenser fan motor is working, use a multimeter to test the incoming voltage to the motor. If the condenser fan motor is receiving the correct voltage, but the motor still won’t run, you should inspect the capacitor, if applicable, for any bulging or leaking. You can also use a multimeter to determine if the capacitor can hold and release its charge. If the capacitor appears to be in good condition, replace the condenser fan motor.
Highly Likely
05 - Goodman Air Conditioner Fan Motor
The fan blades might be scraping against the blower housing. Air conditioners have a fan blade in the front and a fan blade in the rear. Check both fan blades to ensure that they are not rubbing against the housing. If the blades aren’t rubbing against the housing and the fan motor is still noisy, check the fan motor bearings for wear. If the bearings are worn, replace the fan motor.
Highly Likely
06 - Goodman Air Conditioner Blower Wheel
Wiggle the blower wheel to see if it wobbles on the motor shaft. If the blower wheel is loose, try tightening or replacing the set screw screw if it has one. If blower wheel still isn’t stable, replace the blower wheel altogether.
