To secure safe door opening operation by supplying electric power again even when the power supply is cut off during the door opening operation, in a refrigerator comprising a door opening device.
The power supply to the door opening device is started by power-on of the refrigerator (S100), a signal input from a reversing end limit switch of a microcomputer is judged (S110) to transfer to S190 when a slide member is positioned at the reversing end, and to transfer to alarm display (S120) and time lag (S130), to reverse a motor (S140) and to transfer to S150, when the slide member is positioned at a place excluding the reversing end. In S150, the microcomputer judges the signal input from the reversing end limit switch to display alarm, to stop the motor (S170) and then to transfer to ordinary control (S180), when the slide member is positioned at the reversing end, and to transfer to abnormality display (S200), when the slide member is positioned at the place excluding the reversing end.
