Humidifier is excessively loud or vibrates on the table.

Safety first: Unplug the humidifier before opening the housing.

• Relocate unit: Place the humidifier on a solid, level surface. Avoid hollow tables that amplify vibration.
• Inspect fan: Open the housing and check the fan for dust buildup, cracks, or looseness on the shaft. Clean and tighten as needed.
• Check for debris: Remove any foreign objects from the fan area.
• Motor wear: If the motor makes grinding or squealing noises, the bearings may be worn and the motor should be replaced.
