If your GE air conditioner is loud or noisy, the sound usually points to a moving part that is wearing, loose, or rubbing. A worn compressor is the most likely cause of a GE air conditioner making noise, and while a noisy compressor can often keep running for years, replacement should be handled by a licensed professional. Next, check the dual shaft fan motor, since dry or worn bearings can make a window air conditioner noisy or cause an AC making loud noise during operation. Damaged fan blades can also create air conditioner rattling or scraping if the blade hits the housing. If the condenser fan motor is getting proper voltage but still struggles or makes noise, the motor or capacitor may be at fault. A standard fan motor with worn bearings can cause an air conditioner grinding noise, and a loose blower wheel can wobble on the motor shaft.

01 - GE 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.

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.
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.
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.
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.
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.
