Oven makes banging or popping noises when heating or cooling.

Safety First: Allow the oven to cool before touching interior parts.

• Identify source: Remove racks and run a short bake cycle to see if noise decreases. If so, the racks may be the primary source.
• Check racks and supports: Ensure racks are properly seated in their supports and not contacting the oven walls.
• Inspect elements: Look for elements that are touching the liner or warped. Reposition or replace the bake or broil element if necessary.
• Secure panels: Check outer panels and trim for looseness and tighten screws to reduce vibration.
