Summary of reasons why the microwave oven does not heat:

The reason why the microwave oven does not heat may be because the oven door is not closed properly when using the microwave oven. Just close the door again;

Summary 2 of the reasons why the microwave oven does not heat:

The signal line is not connected to the socket, resulting in poor contact, which may also cause the microwave oven to not heat. It is recommended that you contact after-sales service to find out what the problem is;

Summary of reasons why the microwave oven does not heat 2

Summary of reasons why the microwave does not heat:

Check the welding between the socket and the MCU mentioned above. If there is a problem, This kind of weak soldering may also cause the microwave oven not to heat. You can contact after-sales service;

Summary of four reasons why the microwave oven does not heat:

It is possible that the diode is short-circuited, which means You need to replace the diode;

Summary 4 of the reasons why the microwave oven does not heat up

Summary of reasons why the microwave oven does not heat up:

If the voltage is low, it will also cause the microwave oven to fail. When not heating, the voltage at home cannot be lower than 187V, otherwise the high-voltage transformer in the microwave oven will not work, so microwaves will not be generated. It is best to avoid peak periods of electricity consumption;

Summary of six reasons why the microwave oven does not heat:

The microwave oven does not heat. It is also possible that the circuit of the high-voltage transformer has fallen off, causing the microwave oven to not work properly;

Summary of six reasons why the microwave oven does not heat

Summary of seven reasons why the microwave oven does not heat:

Check whether the turntable is rotating, whether the light is on, and whether the fan motor is rotating. If none of them work, you need to replace the inside. of parts.

Summary of eight reasons why the microwave oven does not heat:

Listen and see if the microwave oven makes a "buzzing" sound when it is working. If not, it proves that the magnetron is No work is done, or the working conditions of the magnetron are not met, which also causes the microwave oven to not heat;

Summary of reasons why microwave ovens do not heat 8

Summary of reasons why microwave ovens do not heat:< /p>

Cool the wearing parts in the high-voltage fuse, and then check whether the high-voltage diode, high-voltage capacitor and high-voltage coil are all normal. If there is no problem, then the magnetron may be broken. These are all This may cause the microwave oven to not heat.
