I get no response for that complex website.
It does not paste and even when I tediously type it in, I get no response.
Here is a link to a different site. Hopefully it works. If not, go to searspartsdirect.com. Enter in your model JTP18BD and search. Go to the diagram marked control panel and in that diagram, item number one is the part you need.
How is that different from #16, listed as oven control?
