Microwave oven mica has been punctured. Will a small hole cause the microwave oven to function properly, but it doesn't heat up?
It is very likely that due to overheating protector is bad, can not be caused by protection, resulting in overheating of the magnetron burned out, the use of magnetron has a number of years, but also a comparison of the probability of burning
Mica isolation chamber and the magnetron emitting port, it does not affect the microwave emission, because of high temperature, use for a long time the yellow is normal, but the breakdown is not normal, that once the magnetron work overload, your machine is magnetron burned, need to be replaced, the price is about 80 yuan, pay attention to find the cause of the fault and repair before magnetron replacement.
30 yuan or so can be replaced, if it is the magnetron leader burned, but also to change, mica insulation effect is a very high nature of the material, less it is more prone to failure, must be replaced in a timely manner
