Symptom
Dehumidifier makes loud rattling or grinding noises during operation.
Mechanical Noise from Fan or Compressor Mounts
Symptom
Dehumidifier powers on but compressor never starts; only fan runs continuously.
Compressor Not Starting / Control or Start Circuit Fault
Symptom
Dehumidifier runs but does not collect water even in humid conditions; room still feels damp.
Loss of Refrigerant Charge / Weak Cooling Circuit
Symptom
Dehumidifier shuts off after a few minutes of operation and restarts repeatedly.
Short Cycling / Overheat or Current Protection
Symptom
Dehumidifier vibrates excessively and may move on the floor during operation.

Symptom
Dehumidifier will not power on at all; no lights or display.
No Power / Dead Control Board
Symptom
Humidifier has a strong plastic or burning smell when operating.
Overheating Component or New-Plastic Odor
Symptom
Humidifier or dehumidifier buttons do not respond or respond intermittently.
Keypad / Touch Panel Failure
Symptom
Humidifier produces white dust on nearby surfaces.
Mineral Dust Emission from Ultrasonic Humidifier
Symptom
Humidifier runs but produces little or no mist; water level does not drop.
No Mist Production (Ultrasonic or Evaporative Humidifier)
Symptom
Humidifier shuts off even though the room is still dry; will not maintain set humidity.
Premature Humidity Satisfied / Sensor Placement Issue
Symptom
Humidifier water tank is difficult to remove or leaks when reinstalled.
