What he said. Access to where the wire bridle attaches is through a panel under the sink on the slide wall. Open the slide. Pull enough stuff out from under the sink to remove the panel. You can now reach through the panel, grab the bridle and pull. The door will unroll against the spring. Find something to attach the bridle to so that the door covers the opening. I think mine was attached to a pipe with a cable tie.
