PURPOSE: An air conditioner including a circuit for warning connection error is provided to get a user to know an outdoor unit is not operated because of connection error, not checking the outdoor unit. CONSTITUTION: An air conditioner including a circuit for warning connection error includes a relay(251) opening and shutting power source supplied to an indoor unit(100) from a three-phase power source unit(210); a connection error sensing unit(220) sensing misconnection of the three-phase power source supplied to a compressor(230) from the three-phase power source unit; and a control unit(270) switching the relay according to the result if the connection error sensing unit senses misconnection. Accordingly, misconnection of the three-phase power source is sensed, by checking just the indoor unit, although not checking an outdoor unit(200).
