When the device is turned on, the voltage of 220 V enters the transformer. Passing through the primary and secondary windings, the current of 2 kV already flows at the output of the element. Then the negative half-wave goes to the diode, and the positive one charges the capacitor, which again leads to a twofold increase in voltage. After that, microwave generation begins via the magnetron. The power of the magnetron is regulated by the control unit.
Therefore, when a breakdown occurs, it is worth paying attention to these elements. They bear the greatest load, so the problem often occurs in them.
When disassembling the microwave, be sure to unplug it.
The search for a microwave oven malfunction is carried australia telegram data out based on "symptoms". This allows you to gradually eliminate possible causes and find the real one. So, if the oven does not turn on at all, then it is worth checking the following points:
The position of the door and its closing system.
Status of the network fuse and thermal relay.
In the first case, the situation is elementary - there is no power due to damage to the power cord. A similar situation occurs when the socket is damaged or overloaded. In this case, it is enough to replace this element, everything is fine with the microwave itself.
Next, it is worth checking the operation and position of the door. The fact is that the operation of the microwave oven with the door open is dangerous for others. Therefore, the design provides for the possibility of operation only when it is completely closed. If the latch, locking system or checking element on the door is broken, the protection system will not allow the device to be started.
The last points also concern the oven's protective systems.
