Replacement of the
lamp should be carried out by a qualified appliance repair service.
YOUR
SAFETY IS PARAMOUNT!
Attempt
this only if you are competent.
But here is a basic method if you are
mechanically minded and have electrical safety knowledge.
The lamp is sat in a housing and its
position is adjacent to the vent holes that it shines through.
If
you feel confident, disconnect it from the mains power, remove
anything in the cavity.
Remove the microwave cover. Purchasing a
new replacement lamp will be useful as it will give you an idea of
what it looks like. Locate the dead lamp remove the lamp and fit the
new one. Replace the covers. Plug it back in and try the lamp by
opening the door.
Hope this helps.
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.
