Microwave produces uneven heating; some areas of food are cold while others are very hot.

Safety first: Use microwave-safe containers and avoid sealed containers that can explode.

Step-by-step checks:

• 1. Verify turntable operation: Ensure the tray rotates smoothly during cooking.
• 2. Check stirrer cover: Some Paderno models have a plastic or mica cover on the ceiling hiding a stirrer fan. Inspect for damage or warping.
• 3. Use proper containers: Use round, microwave-safe dishes and stir food halfway through cooking.
• 4. Avoid overloading: Do not stack containers or cover the entire turntable with food.
