AEG 3040B is a built-in single oven with a range of features to make cooking and baking easier and more efficient. It has a hot air cooking system with a fan that circulates hot air around the oven, allowing you to cook on multiple levels simultaneously. This saves time and energy, and is ideal for batch baking or cooking different dishes at the same time. The oven also has a conventional grill setting for grilling meat, fish, or vegetables.

The oven has a range of safety features, including a child lock to prevent accidental operation, and a fat filter to protect the fan from soiling. It also has an electronic timer with a minute minder and auto-stop facility, so you can set the oven to turn off automatically after a specified time.
