Hotpoint Air conditioner is loud or noisy

If your Hotpoint air conditioner is loud or noisy, start by matching the sound to the parts most likely to make it. A worn compressor is often the first suspect when an air conditioner is making noise, although a noisy compressor can sometimes keep running for years and should be replaced by a licensed pro if you choose to replace it. Next, check the dual shaft fan motor, since aging motor bearings can cause a Hotpoint window air conditioner noisy condition. Damaged or rubbing fan blades are also common causes of air conditioner rattling or scraping sounds, especially if the front or rear blade contacts the housing. A failing condenser fan motor, worn fan motor bearings, or a loose blower wheel can also create an AC making loud noise, including grinding, wobbling, or vibration. Inspect these parts carefully before replacing anything. Once you identify the failed component, enter your Hotpoint air conditioner model number on RepairClinic.com to find the exact compressor, fan motor, fan blade, condenser fan motor, or blower wheel that fits your unit.

01 - Hotpoint 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 - Hotpoint 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 - Hotpoint 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 - Hotpoint 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 - Hotpoint 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 - Hotpoint 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.
