Oven makes loud popping or banging noises when heating up or cooling down

Safety first: Disconnect power before tightening any internal screws.

• Identify source: Listen carefully to locate whether the noise comes from the top, sides, or rear.
• Tighten fixings: Check and tighten screws securing elements, cavity panels, and mounting brackets.
• Check element supports: Ensure elements are properly clipped into their supports and not flexing excessively.
• Monitor: Some minor expansion noise is normal; only address if it is excessive or associated with visible movement.
