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

Safety: Use microwave-safe containers only.

User-level steps:

• Check turntable: Ensure the glass tray is correctly seated on the coupler and roller ring, and that it rotates smoothly.
• Load arrangement: Spread food evenly on the plate and avoid stacking thick portions in one area.
• Stir and rotate: Pause cooking to stir or rotate food manually for more even heating.
• Inspect stirrer cover: On some models, a plastic or mica cover on the ceiling hides a stirrer fan. If it is warped, loose, or burned, it can affect heating.

Technician-level steps:

• Inspect the stirrer fan and cover for damage or obstruction.
• Replace a damaged stirrer cover or fan assembly.
• If heating is generally weak and uneven, test the magnetron output and high-voltage system.
