This malfunction may be caused by the following reasons:

After testing the thread, we check the through-capacities for breakdown. To do this, we switch the multimeter to the "continuity" mode, touch the case with one probe, and touch the magnetron contacts in turn with the second one (b in Fig. 6). The normal indicator will be infinite resistance, otherwise everything indicates that the capacity is broken, which means that the magnetron needs to be replaced.
If the magnetron test does not yield any results, it is necessary to measure the input voltages on the device. If they are below the permissible parameters, this may be caused by an interturn short circuit in the high-voltage transformer or a reduced power level in the household electrical network.

Fig. 6. Checking the magnetron

Important! The magnetron must be replaced with a similar netherlands telegram data type. This is due to the fact that the parameters of the high-voltage transformer and control circuit are calculated based on a specific model of microwave generator.

Sparking is observed.


Burnout of the mica plate that insulates the waveguide from splashes and food particles . The plate is located inside the chamber on the magnetron side. The condition is determined visually. If the problem is related to the plate, it is enough to replace it.
During operation, the coupler cover burned out . This is a plastic cap that rotates the tray. In this case, only replacement will help. Naturally, it is necessary to install a coupler from the same type of models, since the design of such a cover can be different even for one manufacturer.
The "wrong" utensils are placed in the chamber . We remind you that metal utensils, as well as those with metallic dyes, cannot be used in microwaves.
The tray does not rotate.

First of all, it is necessary to check whether the tray is blocked by any foreign object, whether it is installed correctly or the separator. If everything is normal, then the reason lies in the drive.
