Jenn-Air Oven bake element melted and no power

My 18 year old electric Jenn-Air oven (W130W) was smoking after a popping sound and then the power went off during preheating. Later discovered the lower baking element was melted at one spot. I found the parts for that but was wondering what else needs to be replaced since no power on the display. Is there a thermal cut-off switch or circuit breaker within this oven? or perhaps the control panel is bad (which now no longer available)?
