Very easy to do. Remove the drawers and the glass shelf. Be very careful with the glass. Pick it straight up. You can’t twist it or flex it at all. REAL careful. There are stories all over the web of this glass just shattering into thousands of pieces in half a second. Once the glass is out the center support is removed. Pull up the end closest to you. The back has a tab so it must be removed by starting at the end closest to the door or you. Once that end is loose just wriggle it out. You will have to pull on the glass shelf support closest to the door. It’s flexible to a point. Slowly and carefully pull the glass shelf support towards you until you can get the center support out. It goes in the same way. Put the back end in first by inserting the tab into the slot. Pull the glass shelf support until you can get the center support in. It’s a total of 5 to 10 minutes.
