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

Safety first: Turn off power and allow the oven to cool before tightening or adjusting parts.

• Check racks: Ensure oven racks are properly seated and not contacting the oven walls.
• Tighten hardware: Inspect and tighten screws securing the back panel, side liners, and element brackets.
• Inspect elements: Look for warped or touching bake/broil elements that may snap or pop as they heat. Replace if severely warped.
• Normal sounds: Some mild popping from metal expansion is normal, but loud or new noises should be investigated.
