Oven makes loud banging, rattling, or vibration noises during operation.

Safety first: Turn off power before tightening or removing internal components.

• Check racks: Ensure racks are properly seated in their supports and not contacting the oven walls. Remove racks one at a time to see if noise changes.
• Inspect elements: Verify that elements are firmly mounted and not contacting the oven cavity. Tighten mounting screws and replace broken supports.
• Convection fan: On convection models, remove the rear interior cover to access the fan. Check that the fan blade is tight on the motor shaft and not bent. Replace the fan blade or motor if noisy or loose.
• Tighten hardware: Inspect internal panels and brackets for loose screws. Tighten as needed.
