Range Surface Burner Cap 316258701

Part needed not included.

I already had the piece which I tried to explain to the service rep. I needed the large burner cap that goes with it. Unfortunately although there is a picture of the burner cap I need in the manual there is no picture of it in the diagram that gives the product number. The rep thought it might be included with the piece she said to order but it was not. The piece is just a ring with no burner cap included. Very frustrated to say the least. She did try hard to help but was not able to due to whoever made the diagram forgot to put in that burner cap. The other 3 burner caps were included in the drawing but as all the caps are different sizes it was not helpful. I returned the piece and am waiting for a refund.
