Humidifier is very noisy or vibrates excessively during operation

Safety: Unplug the humidifier before adjusting or tightening any components.

Steps:

• Relocate unit: Place the humidifier on a solid, level surface. Avoid hollow furniture that can amplify vibration.
• Inspect fan: Open the housing to access the fan. Check for dust buildup or damage to the blades. Clean and replace if cracked.
• Tighten mounts: Tighten screws securing the fan and motor to the frame.
• Check motor bearings: Spin the fan by hand; if it feels rough or wobbly, replace the fan motor assembly.
