  Diana SosaAug 18, 2025
  If the operation lamp on your Daikin Air Conditioner is blinking, you should first perform the diagnostic procedure. Also, ensure all indoor units connected to a multi-system outdoor unit are set to the same operation mode. If they aren't, set all indoor units to the same operation mode and check if the operation lamp stops blinking. You can also try setting all indoor units to cooling or heating mode to see if the operation lamp returns to normal.

  If the Daikin Air Conditioner operation stops suddenly and the operation lamp blinks, it might be due to an operation mode conflict. Ensure all indoor units connected to the multi-system outdoor unit are set to the same operation mode. If they aren't, change them to the same mode and see if the blinking stops. If the mode is set to automatic, try setting all indoor units to either cooling or heating and check again.

Why does mist come out of my Daikin Air Conditioner indoor unit?
- M
  Marissa GrayAug 30, 2025
  Mist coming from the indoor unit of your Daikin Air Conditioner can occur for two reasons: * During COOL operation, room air may be cooled into mist by the cold airflow. * During defrosting, the air in the room is cooled by the heat exchanger and becomes mist.

  Edwin DrakeSep 4, 2025
  If your Daikin Air Conditioner's indoor unit emits an odor, it's likely due to smells from the room, furniture, or cigarettes absorbed into the unit and discharged with the airflow. If this occurs, have the indoor unit cleaned by a technician from the service shop where you bought the air conditioner.
