Thanks for the ideas. It was the second door bracket on the bottom had become loose and screw fell out. Can't believe Thor expects that door bracket screw to stay there when 1 screw was thru 1/4" or less paneling!!!
To keep from moving bracket went ahead with a small toggle bolt. Hopefully that will hold it.
If it happens again may have to move over inch or so to hit nothing but stud. Thx, Dennis.
