Abstract
A control method includes controlling a lever, a pusher and a motor so as to arrange the same in a correct position when electric power is supplied to the home appliance, or the user turns on the home appliance. Abnormalities involving an automatic opening of the door through changes in a return/stop switch and an opening sensing switch while the motor operates so as to open the door may be confirmed.
