If the cap is broken, then there are 2 options:

It is also worth checking the filament winding by connecting the terminals leading to the magnetron to a multimeter. The norm here varies from 3.5 to 8 ohms.
If all previous tests have failed, then the problem may be in the magnetron.
To check the magnetron, simply connect the tester to its power terminals. The tester switches to ohmmeter mode. If the resistance is 2-3 Ohms, this means the device is broken. The same situation if the tester shows infinity. In both cases, the device must be replaced.
The listed elements are the most common culprits of australia telegram data microwave oven breakdowns. However, the device's failure is often associated with other problems, such as problems with the electronic control unit, timer, and other electronic parts. Simple checks with a multimeter will not help here; the help of a qualified technician is required. Although it is much easier to simply replace the part if you are sure that it is broken.
There are frequent cases of failure associated with the destruction of the cap on the magnetron. The thin aluminum case simply cannot withstand the loads and is destroyed under the influence of microwaves. This problem is often found in old devices that are more than several years old. Obvious symptoms in this case are noise and sparks during operation of the device.
To check, it is enough to remove the transformer, because the cap is located in the direction of the food chamber.
Replacing the cap.
Turning the cap over.
The first option is a priority, it is enough to order a replacement or send the magnetron for repair. The second option is considered a temporary alternative, allowing to extend the life of the device indefinitely. It is enough to just rotate the cap 180 degrees around the axis, because the load falls only on one half.
