Microwave heats unevenly; some areas of food are very hot while others remain cold.

Safety: Use only microwave-safe cookware.

User steps:

• 1. Verify turntable operation: Ensure the tray rotates smoothly. Fix any issues with the roller ring or coupler.
• 2. Use appropriate cookware: Use round, shallow microwave-safe dishes and stir food halfway through cooking.
• 3. Avoid overloading: Large, dense portions may require longer time and stirring.

Advanced: If uneven heating persists despite proper use, a technician should inspect the waveguide, stirrer, and magnetron output.
