    Why is my Daikin RYN20CVMB9 outdoor unit leaking water?

      In HEAT mode, the frost on the outdoor unit melts into water or steam during defrost operation. In COOL or DRY mode, moisture in the air condenses into water on the cool surface of the outdoor unit piping and drips.

    Why does my Daikin Air Conditioner smell?

      James RobinsonAug 17, 2025
      The Daikin Air Conditioner may emit odors because smells from the room, furniture, or cigarettes have been absorbed into the unit and are being discharged with the airflow. It is recommended to have the indoor unit cleaned by a technician. Consult the service shop where you bought the air conditioner.

      After operation is stopped, the outdoor fan may continue rotating for another 60 seconds for system protection. Also, when the outdoor temperature is very high, the outdoor fan might start rotating for system protection even when the air conditioner is not in operation.
