- Mica sheet is used to prevent water or oil and other substances from splashing on the magnetron in the process of heating food. If the mica is broken down, the connection part of the waveguide will be ignited and ablated due to moisture and carbon deposition, and the magnetron will be damaged over time. Therefore, it is necessary to replace the aged or damaged mica pieces regularly to reduce the risk of microwave oven damage
