1 high voltage capacitor failure
There is something wrong with the capacitor of the microwave oven, which may lead to voltage surge in the high-voltage circuit, thus causing the fuse to blow.
2 high voltage transformer fault
Transformer failure can also make the voltage out of control, leading to fuse blowing.
3 unstable power supply voltage
The instability of power supply voltage, whether too high or too low, may lead to fuse blowing.
4 Other circuit faults
Such as high voltage diode damage, motor failure, etc. , it may also cause the fuse to blow.
Danger of fuse blowing
Blowing a fuse is no small matter! It not only threatens personal safety, but also affects the life of microwave ovens. If this happens, please be sure to find a professional to repair it to ensure safety!
