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

User-level steps:

• Ensure the turntable rotates freely and is correctly seated.
• Use round, microwave-safe containers and cover food to improve heat distribution.
• Stir or rotate food halfway through cooking, especially for dense dishes.

If the turntable works and proper cookware is used but heating remains very uneven, the magnetron may be weakening and should be evaluated by a technician.
