Common Troubleshooting Issues & Self-Checks

A. Power & Display Issues

Issue: The LED display is off or turns dark
  • Ensure the AC adapter is connected properly.
  • Check if the power outlet is functioning by testing another device.
  • Reconnect the adapter securely to a direct wall outlet.
  • If the adapter is faulty, replace it with a compatible one.
  • If the power supply has damaged the main unit, contact customer support.
Issue: The temperature or humidity display is incorrect
  • Press and hold the temperature button to switch between Celsius and Fahrenheit.
  • To check the set humidity value, press and hold the humidity button for 2 seconds.
  • If the display is flickering or unresponsive, unplug the cabinet for 10 minutes and restart.
Issue: Error Codes on Display (Er Er / 8888 / 0000) or Blank Screen
  •  Check if the power adapter is properly connected to a direct wall socket.
  • If using an extension, try plugging it into a wall outlet instead.

Reset the system:

  • Turn off the dry cabinet.
  • Unplug the adapter from both the socket and the unit.
  • Wait a few minutes, then reconnect and power it on.
  • Allow time for it to stabilise before monitoring.

B. Humidity Control Problems

Issue: The internal humidity level is too high and not decreasing
  • (Note: This does not apply during the first week of use, as the dry cabinet requires time to reach optimal conditions.)
  • Ensure the cabinet door is sealed tightly.
  • If ambient room temperature is below 20°C (68°F), the controller may ice up—move the cabinet to a warmer location and open the door for 5-10 minutes.
  • Allow the cabinet to run without any stored items for at least 8 hours to stabilise.
  • If the issue persists, the controller may be damaged—contact customer support.
Issue: Humidity is dropping too low
  • Ensure the cabinet is not placed in an overly dry environment.
  • Adjust the humidity setting using the control panel.
  • Turn off the dry cabinet and leave the door open for a few minutes to stabilise the humidity level.
  • Turn it back on and observe if the humidity stabilises.

C. Door & Seal Issues

Issue: Door is not closing properly
  • Check if the rubber gasket is clean and intact.
  • Ensure the cabinet is placed on a level surface.
  • If the door is misaligned, slightly adjust the hinges.
Issue: Condensation inside the cabinet
  • Verify that the door seal is not damaged.
  • Minimise frequent or prolonged door openings.
  • Ensure the dehumidifier is functioning properly.

D. Noise & Electrical Concerns

Issue: The cabinet is making unusual noises
  • The dry cabinet operates silently; if you hear humming or buzzing, check the power adapter and ensure it’s securely connected.
  • If the noise is excessive, the fan or electrical components may need servicing.
Issue: Burning smell or electrical fault
  • Immediately unplug the cabinet and stop using it.
  • Inspect for any visible wire damage.
  • Contact customer support for immediate assistance.
