Jenn-Air oven will not bake, only broils

Our Jenn-Air suddenly stopped baking in normal and convection modes; the broiler works fine. When set to bake the broiler kicks on for a short while then shuts off. I removed and tested the bake element with an ohm meter and got a reading of 20 ohms. What other things should I check and how?

Thanks

Apparently no one here.:confused:
