As a rule, the reason is a faulty magnetron

Older models that cannot withstand long-term operation are also susceptible to this "disease". The user could leave the device on for a longer time, which the built-in fan could not handle.
The microwave oven could have heated up from the outside, from the heat in the room. For example, standing near a working stove or in the summer. If you encounter the fact that the microwave turns on and off by itself, the problem is definitely in high temperatures and the thermal relay.
It spins but doesn't heat up.
Sometimes there are situations when the microwave oven works stably, lights up, rotates, but does not heat the food at all. This may not happen all at once, but gradually. Over time, it takes more and more time to heat up the same portion.
This is the main element of the microwave oven design, generating belgium telegram data waves that heat up the food. It breaks down because users place metal objects or dishes with metallized ornaments inside the chamber. This causes sparks and sharp surges of energy.
If this part turns out to be completely serviceable during the inspection, it is worth paying attention to other components. These may be:
transformer;
high voltage diode;
capacitor;
high voltage fuse.
To perform a full diagnostics and repair of equipment such as Daewoo, Vitek, and Rolsen, you will need special knowledge in the field of electronics. If you are not a professional, you should contact a repair service. Independent work with such complex components can be dangerous.
Sparkles
A microwave oven is a fairly complex device that uses complex circuits, methods, and waves. If it starts sparking, crackling inside, or the lamp is blinking, this is not a reason to throw the device in the trash, repairs are possible.
The main problem is the lack of knowledge of users that metal objects cannot be placed inside the oven, except for cases specifically indicated in the instructions.
