Microwave is excessively noisy or vibrates strongly during operation

Safety first: Unplug the microwave before tightening screws or accessing internal parts.

• 1. Level the microwave: Ensure the unit sits flat on a stable surface. Adjust feet if provided.
• 2. Check turntable assembly: Inspect the glass tray and roller ring for chips or warping. Replace damaged parts. Ensure the tray is properly seated on the coupler.
• 3. Tighten external screws: Gently tighten any loose screws on the outer cabinet that may cause rattling.
• 4. Internal fan check (advanced): Remove the cover and inspect the cooling fan and convection fan (if fitted) for debris or bent blades. Tighten fan motor mounting screws.
