What should I do if the air conditioner will not turn on at all?

First, check that the wall plug is firmly pushed into the wall outlet and that the plug's current device has not tripped — press the RESET button on the plug head if needed. Also check if a house fuse has blown or the circuit breaker has tripped, replacing the fuse with a time delay type or resetting the breaker. Finally, make sure the control is set to ON with a desired setting selected. (Page 22)
