Solution: First, people check and unplug the microwave oven, and connect it with another electrical appliance that can work normally to see if it is powered on. If it doesn't work, it means that there is something wrong with the power socket, so people can ask an electrician to repair it. If the appliance can work normally, it indicates that the power supply of this socket is normal. People should check whether the oven door of the microwave oven is tight, whether the switch of the timer is on, whether the power cord is damaged, and solve the problems one by one.
2. The food has an unpleasant smell after repeated continuous processing in the microwave oven, and it can't be heated later.
solution: check the microwave magnetron of the microwave oven. If there is a large area of blackening around the microwave output window in the microwave oven cavity, and a part of the insulating sheet is seriously blackened, people use emery cloth to polish the blackened part in the oven cavity, wipe it clean with alcohol, and then spray it with self-painted paint of the same color for three times. After the paint is dried (about 2 minutes later), replace it with a new insulating mica sheet.
3. The lighting in the microwave oven is not bright, but it can heat food.
solution: the failure of the light indicates that the light bulb of the microwave oven is damaged, so people can just replace it with a new one with the same specification.
4. The microwave oven suddenly caught fire when heating food
Solution: The microwave oven suddenly caught fire when heating food, probably because the food was oily or the food with packaging bags was heated. After the fire, people should immediately cut off the power supply, then wipe off the blackened place with a dry cloth, and finally plug in the electricity and heat a glass of water to see if it can work normally. If not, find someone to repair the microwave oven.
5. The microwave oven can heat food, but it can't automatically turn off the power at the set time.
solution: unplug the power plug of the microwave oven first, and then disassemble the oven shell to check whether the fuse is blown. If it is blown, the fuse with the same specification and model can be replaced. If it doesn't work after replacement, it should be taken for after-sales maintenance.
6, microwave oven panel failure
Solution: Check whether the contacts in the microwave oven are loose, whether the microwave oven door is in place, and check whether the keyboard input circuit or the single-chip microcomputer input port is faulty. If people's touch switch function is normal, and no abnormality is found in the switch connection and peripheral components, it is judged that the single chip microcomputer is damaged. If only a few buttons in the microwave oven fail, it means that the micro button embedded inside is aging and needs to be replaced. If the computer board inside the microwave oven fails, the whole electric board needs to be replaced.
