Haier Air conditioner is loud or noisy
If your Haier air conditioner is loud or noisy, start with the parts most likely to create vibration, rattling, grinding, or motor noise. A worn compressor is a common cause of an AC making loud 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. Its bearings can lose lubrication over time, causing a window air conditioner noisy enough to be hard to ignore. Damaged fan blades are also likely, especially if the front or rear blade is bent, cracked, or rubbing the housing. If the condenser fan motor is receiving proper voltage but still runs rough or will not run, inspect the capacitor and replace the motor if needed. A standard fan motor with worn bearings can also cause an air conditioner grinding noise. Finally, check the blower wheel for wobbling or a loose set screw. Enter your Haier model number on RepairClinic.com to find the exact replacement compressor, fan motor, fan blade, condenser fan motor, or blower wheel for your unit.
01 - Haier 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 - Haier 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.
Top Solution
03 - Haier 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 - Haier 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 - Haier 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 - Haier 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.
