    Abstract: The disclosure relates to a method at a control device (100) for controlling an overhead door operator system, the overhead door operator system (1) being configured for opening and closing an opening (2), and comprising a door frame (3) comprising a first frame section (4) at a first side (7) of the opening (2) and a second frame section (6) at a second side (5) of the opening (2). The operator system further comprises a door (8) arranged to be moved between an open and closed (C) position, the door (8) being movably connected to the door frame (3) and a drive unit (10) mounted on the door (8), the drive unit (10) comprising at least one motor (11) arranged to move the door (8) from the closed position (C) to the open position (O). An elongated transmission member (19) extends along the first side (7) of the opening (2) and the first frame section (4). The drive unit (10) further comprises a driven transmission member (18) in driving connection with the motor (11). The method comprises the steps of: detecting door movement; determining if detected door movement relates to unexpected door movement; and, if so, taking action so as to prevent more extensive damages. The disclosure further relates to an overhead door operator system for opening and closing an opening.

    Abstract: A refrigerator includes a cabinet which has a storage space; a door which opens and closes the storage space; a hinge which connects the door and the cabinet and supports the door so that the door is capable of rotating; and a damping device which is provided on one side where the hinge is mounted and provides a damping force to the door when the door rotates in a closing direction, in which the damping device consists of an oil damper, and a contact surface is formed on one side corresponding to the damping device, with which the door starts to be in contact and thus to which a damping force is transmitted, at a set angle or less, and which is separated from the damping device when the door is opened.
