Oven or cooktop makes loud popping or banging noises during heating or cooling.

Safety first: Turn off power and gas before removing panels.

• Identify source: Listen carefully to locate the area of the noise (back panel, oven cavity, or cooktop).
• Tighten hardware: Remove rear and side panels and tighten any loose screws or brackets.
• Check burner alignment: Ensure gas burners and flame spreaders are properly seated and not contacting other metal parts.
• Note: Some minor popping from metal expansion is normal, but loud or new noises should be investigated.
