Dehumidifier runs but makes loud rattling or buzzing noises.

Safety: Unplug the unit before tightening or adjusting parts.

• External check: Ensure the unit is on a level, solid surface and not touching walls or furniture.
• Inspect fan assembly: Remove the front/rear cover to access the blower wheel or fan blade. Check for cracks and ensure it is firmly attached to the motor shaft. Tighten set screws if present.
• Check for obstructions: Look for wires or insulation contacting the fan.
• Compressor mounts: Inspect the rubber grommets under the compressor. Replace worn or broken compressor mounting grommets.
• Tighten hardware: Tighten any loose screws on panels and brackets.
