Frigidaire Air conditioner is loud or noisy
If your Frigidaire air conditioner is loud or noisy, start by narrowing down where the sound is coming from instead of assuming the whole unit is failing. A wearing compressor is the most likely cause of an air conditioner making noise, and while it can get louder with age, it may continue running for years. Compressor replacement should be handled by a licensed professional. Next, check the dual shaft fan motor. Its bearings can dry out over time and cause an AC making loud noise or grinding sound. Damaged fan blades are also common, especially if a blade is bent or rubbing the housing, which can make a window air conditioner noisy or cause air conditioner rattling. A failing condenser fan motor can also get loud, and its capacitor should be inspected if the motor is not running correctly. If the fan motor bearings are worn, replace the fan motor. Finally, check the blower wheel for wobbling or a loose set screw. Enter your model number on RepairClinic.com to find the exact Frigidaire replacement part for your specific air conditioner.
01 - Frigidaire 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 - Frigidaire 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 - Frigidaire 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 - Frigidaire 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 - Frigidaire 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 - Frigidaire 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.
