Oven emits a metallic clicking or popping noise as it heats and cools.

Safety first: Allow the oven to cool before tightening any screws or touching internal parts.

• 1. Identify source: Listen carefully to locate whether the noise comes from the cavity walls, racks, or rear panel.
• 2. Tighten fixings: Check and tighten screws securing the cavity panels, fan cover, and element brackets.
• 3. Rack fitment: Ensure racks are properly seated in their supports and not warped.
• 4. Monitor: Some clicking is normal as metal expands and contracts. Only investigate further if the noise is very loud or accompanied by performance issues.

If structural distortion of the cavity is suspected, have the oven inspected by a technician.
