Once I get the replacement part, how do I replace?
I looked at the exploded diagram and see that 2 screws attached the front at the bottom, 1 at the top and 4 screws from the inside ( including the handles screws)- so that is straight forward.
I notice that the old glass has portions which are marked “tape”.
and that there are 2 X 1" by 1" small foam blacks on the bottom of the glass.
Put a thick towel on the counter (or table). Remove the door from its hinges and set it on the towel. Be careful not to damage anything, especially glass and door handle. Remove the door handle (#10 screws). Remove the bottom screws that hold #4 outer panel to #9 inner door panel. You can then set the outer panel aside. Collect broken glass pieces if any and install the new glass. Set the outer panel back on, and repeat the other steps in reverse.
Numbers 14 and 14a are aluminum foil/tape peices. That’s all I can see. Don’t use any weatherstrip type material - it’s not hi temp resistant. The whole purpose of the aluminum tape is to reflect heat back to the oven.
