Excessive condensation or steam escaping from oven door during cooking.

Steps to check:

• Inspect gasket: Check for gaps or tears in the door gasket and replace if necessary.
• Locate vent: Identify the oven vent outlet (often at the back of the cooktop). Ensure it is not blocked by foil, pans, or debris.
• Normal moisture: Some steam is normal, especially when baking high-moisture foods. If performance is otherwise normal, this may not indicate a fault.
