Dehumidifier makes loud rattling or buzzing noises during operation.

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

• Check placement: Ensure the dehumidifier is on a level, solid surface. Avoid hollow or wobbly floors.
• Tighten exterior screws: Inspect and tighten all accessible cabinet screws, especially around the fan and compressor area.
• Inspect fan blade: Remove the cover and check that the fan blade is not cracked or rubbing against the shroud. Adjust or replace if damaged.
• Compressor mounts: Verify that the rubber grommets under the compressor are intact and that the mounting bolts are snug but not overtightened.
• Panel damping: If plastic panels vibrate, add thin foam tape between contact points to reduce noise.
