Oven vibrates excessively or buzzes loudly during operation

Safety first: Disconnect power before tightening any screws or accessing internal parts.

• Check installation: Ensure the oven is securely fixed to the cabinet using the correct Ikea mounting screws and brackets.
• Tighten panels: Tighten screws on side panels, top cover, and fan shrouds.
• Inspect fan blades: Replace any fan with bent or damaged blades causing imbalance.
• Listen for relays: A loud buzzing from the control area may indicate a failing relay or transformer; replace the control board if necessary.

Note: Some low-level hum is normal, but strong vibration is not and should be corrected.
