  Heidi MartinJul 31, 2025
  If your Waeco Refrigerator has poor cooling and the interior temperature increases, it could be due to several factors. The ambient temperature might be too high, or there might be insufficient ventilation, requiring you to move the refrigerator to another location. Additionally, a dirty condenser or a faulty fan could be the cause. Consider cleaning the condenser or replacing the fan.

  Kyle MooreAug 5, 2025
  If you hear a loud humming noise from your Waeco Refrigerator, it could be that a component of the refrigerant circuit cannot move freely because it is touching the wall, in which case you should carefully bend the component away from the obstruction. Alternatively, there may be a foreign body jammed between the cooling unit and the wall, so you should remove the foreign body.

  If you attempt to start your Waeco Refrigerator and the display shows "U ?U KL OFF", it could be due to loose cables or poor contact caused by corrosion, so you should establish a connection. Another reason could be that the battery capacity is too low, so you should replace the battery. Finally, the cable cross section might be too small, and you should replace the cable.

  Karen CarterAug 20, 2025
  If the display of your Waeco Refrigerator shows "U = 0 V KL", it means there is an interruption in the connection between the battery and the electronics, so you should establish a connection. Alternatively, the main switch might be faulty (if installed), and you should replace it. Another possibility is that an additional supply line fuse has blown (if installed), so you should replace the supply line fuse.
