Question about Microwave Ovens
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
SAFETY IS PARAMOUNT
This is a job for a professional but if
you are safety clued up, here's instruction.
Make sure the !!!!any capacitors are discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), 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.
