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

Safety First: Use oven mitts when handling hot containers.

• Verify turntable operation: Ensure the tray rotates smoothly. Clean and inspect the roller ring and coupler.
• Check stirrer (if equipped): Some Amana models use a stirrer fan behind a ceiling cover. Listen for its operation and inspect for obstructions or damage.
• Use proper cookware: Use round, microwave-safe dishes and cover food to promote even heating. Stir or rotate food midway through cooking.
• Magnetron performance: If uneven heating persists despite proper operation of mechanical parts, the magnetron may be weakening and require replacement.
