I went on appliancepartspros.com to order glass. Glass arrived but didn't fit. Turns out GE has different part # system that i (of course) didn't know. Called appliancepartspros.com they informed me how this happened and how they would correct it by sending out the correct glass with another order. They would refund my previous order upon return of the glass. They were very responsive, but this shouldn't have happened!
Installation was easy, and the oven is good to go.
