  Michael GregoryAug 9, 2025
  If your LUKO Dehumidifier isn't dehumidifying as expected, several factors could be at play. The air temperature or humidity might have dropped. The humidity level on the controller may need calibration. The unit could be in a defrost cycle. A dirty or clogged air filter can also reduce performance. There might be a low refrigerant charge due to leaks, or air leaks in the ducting. In some cases, the compressor may be damaged, or the air duct isn't properly installed, leading to insufficient air volume.

  If your LUKO Dehumidifier isn't operating, with no fan, compressor, or controller power, consider these potential causes: 1. The device isn't plugged in or lacks power supply. 2. The controller is damaged. 3. Internal wiring is poorly connected. 4. The 3 Phase Protector is faulty, or the phase sequence is incorrect. 5. There's a voltage failure. 6. The Low Pressure Switch is activated, possibly due to gas leakages. Check gas pressure with a refrigerant gauge manifold and inspect the heat exchanger and copper tubes for leakage points if pressure is low.

  If the evaporator coils in your LUKO Dehumidifier are constantly frosting and dehumidification capacity is low, consider these possibilities: * There may be a refrigerant shortage due to leakages. * The air filter(s) might be too dirty, restricting airflow, or the duct connection is improper. * The filter drier could be blocked and require replacement.

How to troubleshoot a LUKO Dehumidifier fan that won't rotate?
- J
  Jose ShafferAug 27, 2025
  If the fan in your LUKO Dehumidifier isn't rotating when the ventilation function is on, and the compressor starts and stops frequently, eventually ceasing to run, check the following: 1. Ensure there are no obstructions preventing the fan from rotating. 2. Check the Controller Pin No.2 for DC Voltage output of 0 – 10V. 3. Verify that the Controller Pin No. 1 (com/gnd) is properly connected. 4. If there's no DC output after checking the controller, replace it. 5. The fan bearing might be worn out. 6. The fan not running could lead to voltage protection. 7. The fan might be faulty.

  Brandon WillisSep 3, 2025
  If the fresh air damper on your LUKO Dehumidifier isn't working, check these potential issues: 1. The connection to the damper may not be properly connected. 2. There might be a loose connection in the ventilation control circuit. 3. A loose connection in the damper power circuit could be the cause. 4. The fresh air damper itself might be defective.
