Disassembling a microwave oven yourself

[shapanwwuom]

If the above reasons are not confirmed, then you need to disassemble the device to find the faults. Before doing this, you must turn off the oven from the network and wait a couple of minutes.

Fuse
What should you pay attention to when looking for breakdowns? There are several basic elements that often fail:

Fuses.
Capacitor.
Diode.
Transformer.
Magnetron.

These elements are directly involved in the operation of the mexico telegram data device and were mentioned earlier. First, you need to check the serviceability of the fuses. Their breakdown is immediately visible, because when burned, the conductor inside is destroyed. If this does not happen, then you should look further.

For further testing, you need to take a multimeter, because it is extremely difficult to find a breakdown on other parts externally. To check the capacitor, you need to switch the device to ohmmeter mode, then connect it to the part. If there is no resistance, the part must be replaced.

High voltage diode
It is impossible to check a high-voltage diode with a tester. It is recommended to replace it if other parts break, because it is often hit. It can be checked using a slightly different method - by connecting it to the network on the way to the bulb. If the bulb is dimly lit or blinks, then the part is in good condition. If it is brightly lit or does not turn on at all, then the diode must be replaced.

Next, the transformer is tested.

It is important to follow safety precautions, because

This element is capable of holding a charge for a long time. It will take several minutes to discharge a working transformer, and much longer if the discharge resistor breaks. It is worth discharging it on the case or not touching it at all if you have no experience working with such equipment.
