Easy fix. Watched a YouTube video on the replacement of an inner oven door window of a similar model, but not the exact same, which gave me confidence to pursue the repair on my own. Turned out to be a very basic job of removing three different sets of screws, removing the broken window, and then carefully installing the replacement part and putting everything back together. Took ~15 minutes to complete.
AppliancePartsPros.com supplied the correct part fast, and customer service was very good to deal with.
Highly recommend attempting this repair as a novice homeowner with basic skills and tools, as well as using AppliancePartsPros.com to obtain the parts and information needed for the repair.
