The outer oven door on my Generation 2000+ G2P 90F/SS oven has smashed as the hinge broke. The top handle has also come off. It appears that the glass is glued onto the metal. Is it possible to replace the outer door or do I need to get a whole new oven? Where would I get a new door? Plus can the oven be used in the meantime as the inner glass door is intact and the oven can be closed.
