Answer Hello Mike,
This is most likely the infinite switch 316436000. There is the possibility of a shorted wiring harness but this is not as likely as a bad switch.
Element will not shut down.
Answer Hello Mel. If the relay is sticking on the control, you will need to order and replace the control board 316557118 on the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
