Oven wont lite or work

You say it will not lite ? I must think you have a gas range and you most likely have a bad ignitor. If the range is electric you may have a bad bake element. You can change this easily from inside the oven. Simply unplug the range, then inside you will see the bake element on the bottom of the oven. You will find two screws holding it in. Remove the two screws and gently pull the element out of the hole. I will have two wires attached. You can remove the wires by simply pulling them off, some will be screwed to the element. You can then check the element with a voltage meter for continuity. If you have none the element is bad. Hope this helps and feel free to call if you need further help.
