The top answer did not help. Had a similar problem, the door slid a bit but not all the way down to the point where it can be lifted. The cause is corrosion of the sliding mechanism which is made of metal (the metal plate that you can see when it slides fully down). My solution was to spray just a tiny bit of WD40 into the small gap that did open, 45 degrees along the bottom edge. The idea is to get just a bit of the WD40 on the metal plate of the sliding mechanism. Then slide up and down until it slides freely.
