Caple oven emits a metallic clicking or pinging noise as it heats and cools.

Safety first: Turn off the oven and allow it to cool before checking inside.

• Check for loose parts: Ensure shelves, side supports, and trays are firmly seated and not rattling.
• Tighten fixings: With the oven removed from the cabinet, tighten accessible screws on side panels and internal brackets.
• Understand normal behaviour: Some mild clicking from expansion is normal and not a fault, but loud or sharp bangs may indicate loose components that should be secured.
