      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.
