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

Safety first: Allow the oven to cool before adjusting internal components.

Steps to check:

• Racks and trays: Ensure all racks and trays are properly seated and not warped.
• Panel screws: Check and tighten accessible screws on the inner panels and fan cover.

Note: Some mild clicking from thermal expansion is normal in Tower ovens and not a fault unless excessively loud or accompanied by performance issues.
