Microwave heats unevenly or takes longer than usual to cook

Safety: Unplug the microwave before internal inspection.

• Check turntable: Ensure the turntable rotates smoothly and is not overloaded with large dishes that prevent rotation.
• Use proper cookware: Use microwave-safe, non-metallic containers and avoid stacking food too high.
• Compare heating: Perform a water heating test (e.g., 1 cup of water for 2 minutes). If heating is significantly weaker than expected, the magnetron or stirrer system may be failing.
• Internal components (advanced): A technician can inspect the mode stirrer (if equipped) and magnetron output.
