Question about Microwave Ovens
It looks like the magnetron or a component like a capacitor or a resistor on the control PCB may be failing or is kaput.
It is best you take this to a service center or the point of purchase and get a qualified technician to look at it. It can be hazardous to open the microwave yourself, if you have no prior experience.
If it is still under warranty, I recommend you get it replaced.

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
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 capacitor can fail and go 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
