If an oven turns on but won't stay on it could be due to a faulty thermal fuse that trips if the oven overheats. If this is blown the oven won't turn on at all. One of the relays on the relay control might be faulty as well, in that case a new board is required. A faulty main control board is a common cause as well.
Bake and Broil Elements: These main elements can burn out over time. They can crack and get holes. Best to inspect them for damage.
Igniter: Igniters are the number one cause of an oven not turning on. Igniters open the safety valve and heat up to ignite the gas in the burner assembly. It can be tested with a multimeter for continuity and replaced if necessary.
