Small microwave oven is a kind of household appliances, which is often used for quick heating, cooking, thawing and other functions. However, if there is something wrong with the small microwave oven, how can we repair it? The following are some common problems of small microwave ovens and their repair methods:

1. The turntable of small microwave ovens is driven by a motor. If the oven is not rotating or the speed is slow, first check the motor and its operation. First rule out whether the power supply is normal, and then check whether the motor connecting wire is in good contact. If the connection is good, but the motor still doesn't work, then it may be a motor fault and the motor needs to be replaced.

2. No heating

Electromagnetic wave is the main tool to produce the heating effect of microwave oven. If the microwave oven is not heated or the heating effect is not good, then the problem may be that there is something wrong with the microwave tube. Microwave tube is the core component of microwave oven heating, and the fuse on it may melt or have other faults, so it is necessary to replace the microwave tube at this time.

3. The display is out of order

The digital display of the small microwave oven is used to display cooking time and other information. If the monitor is out of order, it may be the monitor itself or the internal circuit. At this time, the microwave oven needs to be disassembled to check the internal circuit. If the circuit is normal, the monitor needs to be replaced.

4. The trigger is out of order

The trigger is one of the important parts in the microwave oven, which is mainly used to control the discharge time and power of the microwave oven. If the trigger fails, the performance of the microwave oven will be affected or even unable to work normally. At this time, it is necessary to check whether the connection and circuit of the trigger are normal, and if there is any problem, it is necessary to replace the trigger.

in short, if there is a problem with the small microwave oven, we should first carefully investigate the cause of the problem, determine the parts where the fault is located, and repair or replace them to ensure that the microwave oven can work normally and ensure the safety of use. If you are not familiar with the maintenance of microwave ovens, it is recommended to seek the help of professional maintenance personnel.
