Mica chips are used to protect food from splashing water or oil onto the magnetron tube during heating. The excellent insulation properties of the mica chip in the microwave oven help protect the magnetron that emits microwaves, ensuring proper operation and extending its lifespan. The mica piece is brittle and easy to break, so do not overbend. Clean the mica cover regularly, keep it clean, dry, and oil-free, and replace damaged or contaminated mica pieces promptly.
