The frequency converter of microwave oven is one of the core components of microwave oven, and its function is to adjust the heating power of microwave oven. The failure of the inverter will cause the microwave oven to fail to work normally, and it needs to be repaired at this time. Here are some methods of frequency conversion maintenance of microwave ovens.

1. Check the inverter power supply.

First, check whether the power supply of the inverter of the microwave oven is normal. If the power supply is abnormal, there may be something wrong with the socket or power cord. Check whether the power cord is plugged into the socket and whether the socket has electricity. If the power supply is normal, whether the switch is normal.

2. Check the microwave oven control panel

The control panel of microwave oven is another core component of microwave oven. If there is something wrong with the control panel, it may affect the operation of the inverter of the microwave oven. Check whether the control panel is normal and whether the buttons on the panel can react normally.

Check the fan.

The frequency converter of microwave oven generates a lot of heat, which requires heat dissipation measures. Check whether the fan of the microwave oven works normally. If the fan is not normal, it may cause the inverter of the microwave oven to malfunction.

4. Replace the frequency converter

If there are no problems with the above three points, it is likely that the inverter of the microwave oven itself has failed. It needs to be replaced at this time. You can choose original fittings or fittings with the same parameters for replacement.

The maintenance of microwave oven inverter requires certain professional knowledge and skills, and it is not recommended for non-professionals to replace it themselves. If you can't repair it yourself, it is recommended to let professionals carry out maintenance.
