Excuse me, the mica sheet is a little burnt. What's the matter?
Also, the function of mica is to prevent heating objects from splashing to the magnetron, and pay attention to them when they are used.
One possibility is that the mica sheet is splashed with oil, which causes Microwave Refraction, high temperature and scorch the mica. In that case, it doesn't matter. The test method is to remove the mica plate and turn on the microwave oven to see if it is normal. Normally, that's what it says. If not, then it could well be that the magnetron burned out and the magnetron was expensive!
Mica made of special material you can call customer service service first try to see how they say if the warranty period to ask them for a little money and then look at the other home appliance repair place to change how much money a person is on the microwave oven mica to scatter the microwave heating and do not use something else instead of radiation don't say the key is not security health but if the microwave oven is 7, more than 8 years, I suggest you can change a hope can help you.
