Why does the microwave oven work louder
Among household appliances, the microwave oven is an electrical appliance with a relatively loud working sound, which is closely related to the working principle of the microwave oven, because the microwave Two conditions are inseparable:
1. High voltage: It is equipped with high-voltage components such as high-voltage transformers and magnetrons, and the process of rectification and voltage doubling during operation leads to high hum.

2. Heat dissipation: Since the microwave emission tube of the microwave oven will generate more heat when it works under high pressure, the microwave oven is equipped with a cooling fan, and the fan will inevitably produce higher sound when it is working.
According to the requirements of the country, the operating sound of the microwave oven should be controlled within 50 decibels, while the working sound of the general microwave oven is about 30 decibels, so the “hum” sound in the microwave oven is the normal working sound of the microwave oven , you can use it with confidence.
In addition to the loud noise caused by the construction of the microwave oven itself, the noise of the microwave oven can sometimes be made louder for other reasons.
1. The bottom surface of the placement position is uneven, causing the turntable in the oven to shake (just adjust the placement position of the microwave oven).
2. The service life of the microwave oven is too long, and the components are aging (such reasons will not affect the normal use of the microwave oven).
3. The high-voltage transformer in the microwave oven resonates with the outer casing of the microwave oven. This reason can be solved by the microwave oven maintenance personnel.
Note: The above descriptions are all under the condition that the microwave oven can be heated normally, except for the malfunctioning machine.
