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

Safety first: Ensure the appliance is cool before tightening any screws or panels.

• Identify source: Listen carefully to locate the general area of the noise (back, sides, top).
• Check for loose parts: Tighten any loose screws on panels, racks, and brackets.
• Normal vs abnormal: Some popping is normal as metal expands. Very loud or grinding noises may indicate a loose fan blade or component that should be inspected.
