High-pitched squealing noise when opening or closing the oven door.

Safety first: Ensure the oven is cool. Do not use flammable lubricants near hot surfaces.

• Inspect hinges: Open the door fully and examine the hinge arms for damage or misalignment.
• Clean hinge area: Remove any visible debris or baked-on grease from the hinge slots.
• Lubricate sparingly: Apply a small amount of high-temperature, food-safe lubricant to the hinge pivot points (avoid overspray on gasket or cavity).
• Replace hinges if noise persists: If squealing continues or the door movement is jerky, replace both hinges as a set.
