Dehumidifier makes loud rattling or vibrating noises during operation.

Safety: Unplug the unit before tightening or removing parts.

Steps:

• Check placement: Ensure the unit is on a solid, level surface. Avoid hollow or wobbly floors.
• Inspect exterior: Check for loose panels or screws and tighten them.
• Access fan: Remove the front or rear panel to inspect the fan blade. Ensure it is firmly attached to the motor shaft and not cracked.
• Remove debris: Clear any foreign objects from the fan area.
• Compressor mounts: Inspect the rubber grommets under the compressor. Replace if cracked or missing.
• Test: Reassemble and run the unit. If noise persists and seems to come from the motor or compressor internally, professional service may be required.
