HELP!! My husband and I are going crazy. We put in new bi-fold doors in my son's closet. Thr problem is that they don't seem to close all the way. I thought that maybe the dried paint on the hinges was keeping it from closing all the way but that doesn't seem to be the problem. THen my husband put a magnet on the bottom of the bifold to hold it closed that way but that isn't working either. We even changed the tracking. This has gotten us both stumped and going crazy. Please help!!
