I dont know about your particular model but with a lot of trays you pull it fully out and along the top at the back is a little part usually in the middle that you press down gently and pull the tray out lifting it slightly at the front.Replace the tray by tilting it up slightly then lower it just as you would a kitchen draw and push it home,if it slides in as normal,without force,it will click in place itself,its worth a look.Good luck.Rich.
