Oven makes loud banging or rattling noises during operation.

Safety: Turn off power before tightening or adjusting internal parts.

• Identify noise source: Run the oven briefly and listen to locate whether the noise comes from the rear (fan), top (cooling fan), or cavity (racks/panels).
• Check racks and trays: Ensure racks are properly seated and not warped. Remove accessories one by one to see if noise stops.
• Tighten screws: With power off, tighten any loose screws on internal panels, fan housings, and brackets.
• Inspect fan blades: Check that the convection fan blade is tight on the shaft and not bent. Tighten or replace as needed.
• Replace noisy motor: If the fan motor makes grinding or squealing noises, replace the motor.
