      nmedinaAug 11, 2025
      If your Daikin Air Conditioner's outdoor unit is emitting water or steam, this is normal. In HEAT mode, 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 the outdoor fan on my Daikin FTXS25D3VMW(L) keep running when it's off?

      Lisa McmahonAug 21, 2025
      If the outdoor fan of your Daikin Air Conditioner rotates even when the unit is not in operation, this is normal. After stopping the operation, the fan may continue rotating for 60 seconds for system protection. Also, when the outdoor temperature is very high, the fan might start rotating for system protection.
