Dehumidifier vibrates excessively or makes rattling noises during operation.

Steps:

• Level the unit: Place the dehumidifier on a flat, solid surface. Adjust position so it does not rock.
• Check for debris: Unplug and remove covers to inspect the blower wheel and fan area. Remove any foreign objects.
• Tighten mounts: Check screws and bolts securing the fan motor, compressor, and panels. Tighten any that are loose.
• Inspect isolators: Examine rubber grommets under the compressor and fan motor. Replace worn or cracked vibration isolators to reduce noise.
