Question about Siemens Microwave Ovens
I wonder if this is an inverter-based model... I ask because on Panasonic/Quasar units, a problem with the magnetron or inverter will cause this very symptom.
If so, because of the voltages and currents involved, I do not recommend that someone without experience attempt repairs on an inverter circuit.
I would contact the manufacturer at the number in your owner's manual to find the nearest authorized servicer.

The magnetron may have either failed or
is not being supplied with the extremely high voltage required to run
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.
