Microwave produces a metallic taste or odor in food.

Steps:

• Deep clean: Thoroughly clean the interior with a mild detergent and water. Avoid harsh abrasives that damage enamel.
• Inspect for arcing damage: Look for black burn marks or pitting on the cavity walls and around the waveguide cover. Replace the cover if damaged.
• Use proper cookware: Only use microwave-safe glass, ceramic, or plastic. Avoid metal-trimmed dishes.
• Test: After cleaning and repairs, heat a cup of water and check for any residual odor.
