Every oven with an interior light also has a light switch. The switch is usually located on the control panel or on the frame of the oven and the door normally activates it when closed. If the oven light is out and the bulb is good, the light switch might need to be replaced. Test the switch with an Ohm meter to see if it has continuity.
