Abstract
An air conditioner includes an inlet for receiving room air, a heat exchanger for heating or cooling the air, an outlet for discharging the heated or cooled air back into the room, a fan for circulating the air through the air conditioner, inlet and outlet doors for opening/closing the inlet and outlet, a motor for driving the doors, and a controller for automatically actuating the motor to open the doors when the air conditioner is activated, and close the doors when the air conditioner is deactivated. A control by-pass is provided in a remote controller which is relatively inaccessible to a normal user but which can be actuated by an air conditioner tester or shipper for maintaining the doors open even when the air conditioner is deactivated (e.g., during testing or shipping) to prevent the doors from being damaged.
