Dehumidifier makes loud rattling or vibrating noises during operation

Safety first: Unplug the unit before tightening or touching internal parts.

Steps to reduce noise:

• Level the unit: Place the dehumidifier on a flat, solid surface. Adjust feet if provided.
• Tighten screws: Check and tighten visible cabinet screws on the sides, back, and top.
• Inspect fan and blower: Remove the front grille and check that the fan blades and blower wheel are secure on their shafts. Tighten any accessible set screws or clips.
• Add padding: Place a thin rubber mat under the unit to absorb vibration.

If noise persists and seems to come from the compressor area, the compressor mounts or internal components may be worn and require professional service.
