Spoke with Chuck at AppliancePartsPros.com who told me which part to order. Purchased part, which arrived promptly, and replaced part. Just swapped out old one for the new one. Entire job took only about 10 minutes to complete. Saved me the hassle of trying to find a new gas double oven that would fit in the existing opening, not to mention the expense of a brand new double oven. Thanks AppliancePartsPros.com! You guys are awesome!
