WeatherKing Air conditioner is loud or noisy
A WeatherKing air conditioner that is loud or noisy usually points to a moving part that is wearing, loose, or rubbing. If the air conditioner is making noise from the compressor, the compressor may be wearing out, although many noisy compressors keep running for years and replacement should be handled by a licensed professional. More often, an AC making loud noise comes from the dual shaft fan motor as its bearings lose lubrication, or from a damaged fan blade rubbing the housing. A noisy condenser fan motor can also be the problem, especially if it receives proper voltage and the capacitor tests good but the motor still will not run correctly. If the fan blades are clear but the unit still has an air conditioner rattling or grinding noise, check the fan motor bearings. A loose blower wheel can also wobble on the motor shaft and create vibration or scraping. Enter your WeatherKing model number on RepairClinic.com to find the exact replacement compressor, fan motor, fan blade, condenser fan motor, or blower wheel for your specific air conditioner.
01 - WeatherKing 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 - WeatherKing 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 - WeatherKing 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 - WeatherKing 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 - WeatherKing 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 - WeatherKing 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.
