Gas Range Oven will not heat

I have a GE Profile 30" gas range model JGBP86BEB1BB my oven will not heat but the broiler will. I do not get any error messages on the front panel. I am very mechanical and want to fix this problem myself. I am looking at the igniter as the possible problem. Does anyone have other suggestions? I am also looking for a repair diagram

The model number posted shows a gas top and an electric oven.

Here’s the breakdown http://www.appliancepartspros.com/partsearch/model.aspx?model_id=214184

If this is the correct model number check the element and wires to it. There is also a sensor (part #238 on page 4) you may want to check.
