  If your Daikin Air Conditioner isn't operating, first check for a power failure and wait for the power to be restored. If there was a power failure during operation, the system will restart automatically. Also, check if a fuse has blown or a breaker is activated, and replace the fuse or reset the breaker if needed. Finally, check the batteries in the user interface.
