Fan Motor Failure
Whisper, Whisper Flex, and related fan models may continue oscillating while the main fan blades stop spinning. Duux identifies a defective motor as the most likely cause when this occurs.

2 Most Seen Failures:
Oscillation Motor Failure
Duux fans can lose horizontal or vertical oscillation while other fan functions remain operational. Duux attributes persistent loss of oscillation primarily to a defective oscillation motor.
Humidifier Mist Failure
Tag, Beam, and Beam Mini humidifiers may stop producing mist or produce extremely weak/intermittent mist despite powering on. Causes range from water-path contamination or improper reservoir levels to failure of the internal fan responsible for moving the mist upward.
Water Leakage
Tag, Beam, and other Duux humidifiers can develop leakage around the reservoir or tank connection. A stretched or deteriorated tank-cap O-ring is a documented failure point on Tag models, while other models may require service when leakage develops.
Display / Control Panel Failure
Whisper Flex and related models can develop defective displays or control interfaces that no longer illuminate or operate correctly. Duux specifically recognizes display failure as a service or replacement condition.
Temperature / Environmental Sensor Failure
Duux air conditioners, dehumidifiers, and air purifiers can develop faulty temperature, evaporator, coil, or air-quality sensors. Examples include E0/E3 errors on North air conditioners, E1/E2 faults on Bora dehumidifiers, and persistently abnormal readings on Bright air purifiers.
Compressor Failure / No Cooling
North and other Duux portable air conditioners may power on while the compressor fails to start, resulting in little or no cooling. Overtemperature protection can temporarily stop the compressor, but a persistent condition requires service.
Fan Blade Imbalance / Wobble
Whisper, Whisper Flex, and Whisper Flex Ultimate models can develop visibly wobbling or unbalanced fan blades. Duux treats persistent blade imbalance as a component fault and provides replacement blades when applicable.
Abnormal Mechanical Noise
Duux fans can develop persistent ticking, cracking, rattling, or other mechanical noises during operation. If correct assembly does not eliminate the noise, Duux directs the unit to service, indicating a mechanical fan, drive, or mounting fault.
