then Ill include this link as well, which is apart breakdown for your GENERAL oven, and i do this so you can see the different panes of glass( ther are 4 of them inthe oven door, each one different so ordering hte right one will be half the battle.

the numbers after you model example, kemc308kss** (01,02,03,04) these last 2 digits will also determine which glass you actually have

Once the door is off and you have the correct glass, changing the glass is nothing more then reomving screws from the door frame, layer by layer until you get to the broken pane, not real difficult at all
