There is a large capacitor connected to the magnetron
circuit (usually thick red wire) short across its
termials with a well insulated screwdriver and hold
for a couple of seconds. If the microwave has not been
used for some time then their should not be any charge
on the capacitor anyway. The magnets around the
magnetron are usefull. After unscrewing the mounting
screws and cutting the wires you need to remove the
screening lid on the base to allow access to cut the
heater wires so that when you leaver off the end
plates (first prize opent the 'C' slot that holds the
plates in place) you can extract the magnetron tube
from the assembly and remove the magnets. The
magentron is glass and under vacuum so wear protection
so that if it should break you are well protected.
After removing the couple of turns for the heater
winding I found the best way to remove the secondary
windings was to use a slitting saw in a dremmel clone
cutting close to the laminations. You can then punch
out the cut stack. Protect the primary windings (and
your fingers) as the slitting saw does have a mind of
its own. And then just
The relay that is mounted on the PCB can also be
usefull as it has a high current rating for its
contacts.

I got a free microwave and want to take it apart but
need to be sure i do it safely. Have heard about
the
residual build up of voltage in the capacitor.
Can someone give me a procedure to properly
discharge
it so I can begin?
Any other things to watch out for?
Thanks very mcuh,
