Whether it is possible to turn on the oven light without opening the oven will depend on the specific design and features of your oven. In many ovens, the light is typically connected to a switch that is activated when the oven door is opened or when a specific control on the oven is activated.
However, some ovens may have a separate control or button to turn on the oven light independently, allowing you to illuminate the interior without opening the oven door. This feature is often useful for checking on the food or monitoring the cooking progress without disrupting the cooking process by opening the oven door.
It is best to consult the user manual or refer to the specific instructions for your oven model to determine if it has the capability to turn on the oven light without opening the oven door.
