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

Safety: No immediate hazard is usually present, but inspect if noises are extreme.

• Differentiate normal vs abnormal: Occasional pops and pings are normal as metal expands. Continuous grinding or scraping is not.
• Check racks and accessories: Ensure racks are properly seated and not contacting the oven walls.
• Inspect fan: If noise seems from the rear, check the convection fan for loose screws or contact with the shroud. Tighten or adjust as needed.
