JENN-AIR JEC0536 IS THE # XXXXX MY UNIT AND BOOK THE UNIT IS BLACK IF THAT HELPS. I FOUND IT ON THEIR PARTS LISTING ON LINE.
Okay found it. on these units you need to lift the whole unit out of the counter top and remove the screws all the way around the outside of the glass top frame. heres a diagram but it doesn't show the screws but gives you an idea on how this goes together.
you can see the glass top frame in this picture.
