    Why is the cooling or heating effect poor on my Daikin RK35JV1NB Inverter?
    • W
      William ClarkAug 18, 2025
      A poor cooling or heating effect from your Daikin Inverter could be due to several reasons. Ensure the air filters are clean and that nothing is blocking the air inlet or outlet of either the indoor or outdoor units. Check if the temperature setting is appropriate, and make sure windows and doors are closed. Also, verify that the airflow rate and direction are set correctly and that the unit is not set to Intelligent Eye mode.

    Why does my Daikin RK35JV1NB outdoor unit emit water or steam?
    • M
      mooreashleyAug 20, 2025
      The outdoor unit emits water or steam due to the following reasons: * In HEAT mode, the frost on the outdoor unit melts into water or steam when the air conditioner is in defrost operation. * In COOL or DRY mode, moisture in the air condenses into water on the cool surface of outdoor unit piping and drips.

    • E
      Elizabeth FlemingAug 30, 2025
      If your Daikin Inverter isn't operating and the OPERATION lamp is off, check a few things: see if a breaker has turned OFF or a fuse has blown. Also, check for a power failure. Ensure batteries are correctly installed in the remote controller, and verify that the address switch in the remote controller is set correctly. Finally, confirm that the timer setting is correct.

    Why does my Daikin RK35JV1NB indoor unit give out an odor?
    • C
      Cynthia DavidsonSep 3, 2025
      The odor from your Daikin Inverter's indoor unit occurs when smells from the room, furniture, or cigarettes are absorbed into the unit and discharged with the airflow. If this happens, it is recommended to have the indoor unit cleaned by a technician. Consult the service shop where you bought the air conditioner.
