Microwqve flickers and shuts off

Question

Hi, we have the above mentioned model microwave which we are experiencing problems with it. When cooking some things ( it seems like it may be smaller items that cause the problem), the electronic display flickers and the unit shuts off. Sometimes the fan comes on before the unit shuts off also.

We can restart the microwave if we cancel the time, but the problem repeats itself.

Has anyone experienced the same and can you provide advice?

Thank you,
KAB
