The role played by the mica sheet in the microwave oven:
Microwave oven in the process of heating food, to prevent water or oil and other substances splashed on the magnetron, to play a protective role. Due to the absence of mica sheet will cause the connection part of the waveguide due to moisture and carbon accumulation will occur due to firing ablation phenomenon, a long time will damage the magnetron
Mica sheet can be microwave penetration and high insulation, will not be the role of the microwave and electromagnetic reaction will not occur due to the role of the microwave and the quality of change.
NOTE:
In daily use, pay attention to regular cleaning of the mica sheet to keep it clean and dry without oil and dirt. If the surface is found to have lighted scorched, the mica sheet should be replaced immediately to ensure that the magnetron will not be damaged.
This mica sheet can be used in many makes and models of microwaves and ovens and can be replaced normally as long as it is the same size and shape.
The mica sheet is simple to install and easy to operate. Do not forget to clean the mica sheet during daily cleaning, and pay attention to keep it clean and dry.
It is recommended to replace the mica sheet regularly, its quality directly affects the function and service life of the microwave oven.
