Oven door glass is loose, rattling, or has fallen out.

Safety first: Ensure the oven is cool and wear cut-resistant gloves when handling glass.

• Remove door: Open the door fully and release the hinge locks (if fitted) to lift the door off the oven.
• Disassemble door: Lay the door on a soft surface and remove screws holding the inner and outer panels together.
• Inspect clips and brackets: Replace any broken glass retaining clips or brackets with genuine parts.
• Re-seat glass: Clean the glass edges and frame, then refit the glass panels in the correct order. Tighten all screws evenly.
• Reinstall door: Refit the door onto the hinges and lock them in place.
