My glass on the oven was broken.

All I needed was a phillips screwdriver to
take two screws out of the top panel. Then the two side panels pop off. Notice there are three click
tabs on each side panel, and also that the top and
bottom of the left and right panels, must be
manipulated in a sliding action(front to rear
facing the oven door front.) A good deal of
hand force is need to accomplish this.
Clean the old glass out, put the new glass in,
carefully might I add, and reverse the above
process. Just a little mechanical inclination
will get you there. Good luck!
I almost forgot to add that this job goes a lot
easier if before all of this, you simply remove the
oven door from the oven, by opening the door
about ten inches to the point where it stands
open on its own, then grasping it firmly on both sides and pulling up, with a slight jerking action.
This breaks it loose so it can very very easily be removed, and replaced. Best of luck!
