We continue to unscrew the screws and remove the covers

Next, lift the cover up a little and pull it towards you. This way, it comes out of the grooves located on the front part of the case.

You may notice traces of carbon deposits that have formed as a result of exposure to high temperatures.
The removed cover frees access to the main elements of the microwave oven (Fig. 13). At the top, you can see the grill elements - the heating element located in a special housing.

On the left is the magnetron itself (Fig. 14), namely its new zealand telegram data upper part.

At the bottom left is a power filter, from which a wire clamp and a network cable come off. Also on the top of the camera, you can see two temperature sensors. They are attached to the body and react to temperature changes. Two wires are connected to them.

If you look from the side, other elements are revealed to the eye. For example, a power transformer with a step-up winding.

We also see the magnetron radiator.

And we examine the power switch.

Time relay with an audible signal, the role of which is performed by a mechanical bell (Fig. 19).

Magnetron radiator blower (Fig. 20). It prevents overheating of this important expensive part.

There is almost nothing on the right side (Fig. 21).

Let's start with inspecting the power filter, because it is where the network cable comes in, and then the voltage from the board goes to other elements of the oven. Therefore, the place where the voltage "disappears" must be looked for from the side where it comes in, that is, the network cable.
