keeping the oven door slightly open when using the broiler was recommended for some ovens to prevent overheating. However, oven designs and safety standards may vary, so it's always best to follow the specific instructions provided in your oven's user manual.
The reason for keeping the oven door slightly open while broiling is to allow air circulation and prevent the oven from getting too hot. Broiling involves cooking food at high temperatures directly under the broiler element, which can generate a lot of heat. In older ovens or certain models, this intense heat can build up inside the oven, and keeping the door slightly ajar allows excess heat to escape.
Modern ovens often have safety features and built-in mechanisms to handle the heat generated during broiling more efficiently. Some newer ovens may not require you to keep the door open while broiling, and doing so might even interfere with the cooking process by affecting the broiling temperature and cooking time.
To know the specific recommendations for your oven model, refer to the manufacturer's manual. If you can't find the manual, you can search for your oven model online to access the information or contact the manufacturer directly for guidance. Following the manufacturer's instructions ensures safe and optimal usage of your appliance.
