Final answer:
Maintenance of an oven includes cleaning, checking temperature accuracy, inspecting door seals, replacing faulty elements, and general maintenance such as ensuring racks are secure and the oven is well-ventilated for safety.
Step-by-step explanation:
The key items you are responsible for maintaining when it comes to an oven include ensuring it's kept clean, monitoring its temperature accuracy, checking the door seals, replacing any faulty elements, and staying on top of general maintenance.
For example, after baking a cake for your last birthday party, you should clean any spills to prevent smoke and potential fires next time the oven is used. In addition, just like needing to wear an oven mitt to take a hot cake out of the oven, properly maintaining your oven also involves safety precautions such as verifying that the oven racks are secure and that the oven is correctly installed and ventilated.
