Most times the elements burn out while they're on ( kind of hard for something electrical to break while in the off position).
Go turn the oven on in the bake position. If the bottom element heats up, it is fine; in which case its the t-stat.
Neither bake nor broil works......
Yeah, I saw that after I posted originally. I edited the post.
Unless, other information has been posted while I am typing this, it seems like it's the bake/broil switch. If it's analog, it's relatively simple and inexpensive to fix. If it's digital, it would probably be on a circuit board.
