If your Ferroli Air Conditioner isn't starting when you press the ON/OFF button, check that the power cord is properly plugged into the mains socket and that there's voltage in the socket. If it still doesn't work, wait 3 minutes before restarting the unit. If the problem continues, it may require professional service.
