  If your Daikin Air Conditioner isn't turning on, check the following: * See if a fuse has blown and turn off the power supply. * Check if the power circuit breaker is blown. If the tab is in the OFF position, turn it on. However, if the tab is in the trip position, do not turn it on and contact your local dealer. * Make sure direct sunlight isn't entering the room. Use curtains or blinds. * Consider if there are too many people in the room. * Assess if the heat source in the room is excessive.
