Common solutions for: Bath fan motor is loud or noisy
Solution 1:
Fan Motor
The exhaust fan motor bearings might be worn out. To determine if the bearings are worn out, wiggle the motor shaft back and forth. The motor shaft should not move at all. If the motor shaft moves eve...n slightly, this indicates that the bearings are defective. The bearings are not repairable—if the bearings are worn out, you must replace the motor.
