  If your Daikin Air Conditioner system isn't operating, here are a few things to check: * Ensure there is no power failure and wait until power is restored. Note that if a power failure occurs during operation, the system will automatically restart immediately after the power supply recovers. * Check if no fuse has blown and turn off the power supply. * Check if the breaker is blown and turn the power on with the breaker switch in the Trip position.

  If your Daikin Air Conditioner system is running but the cooling or heating isn't effective, consider the following: * Make sure that the air inlet or outlet of the outdoor or indoor unit is not blocked by obstacles. Remove any obstacles to ensure good ventilation. * Check if the remote controller display indicates it's time to clean the air filter. If so, clean the air filter. * Verify the temperature setting. * Check the fan speed setting on your remote controller. * Ensure that doors and windows are closed to prevent drafts. * Reduce the number of occupants in the room during cooling. * Minimize heat sources in the room during cooling. * Use curtains or blinds to block direct sunlight during cooling. * Ensure the air flow angle is properly adjusted.
