While you're at it, you should also get the 5 point variety. I had to
do that to tear apart a Seagate USB disk drive enclosure:

Thanks for the link,Jeff!
I could have used these a few weeks ago,on my Nissan Sentra SpecV MAF
sensor.
I was able to get the screws out by bending the center pins just enough
to allow the hole-less Torx key to catch the 6 faces in the screw. Then
I brought them to a strong vice and I flattened said little pins with a
few whacks. Now I can do some real screwin' :-)

OK guys, I have installed the diode but I was unable to find a wave
guide. I have seen pictures of guides - a small channel to direct the
waves. but I have no such channel, unless it is the short duct between
the magnetron and the oven wall.


That is the waveguide, AKA a duct to carry the RF into the oven
cavity.


On the inside of the wall there is a plastic plate about 5" x 3". The
oven has a curved back inside.


Take a look under the plastic plate for bugs or grease.


Presumably the waves get scattered all around inside. The inside is in
pristine shape - I could see nothing like small burn holes.

My situation now is whether to try to start it up or start taking
measurements. There is a small pamphlet with some measurement
guidelines.


Interesting discussions :-)

If we may return to the original topic for a moment, I reassembled everything
and now there is a loud hum. so I guess another component was busted when the
diode went.

Any suggestions? I know there is some info above and I'll look for it later today.

Thanks to all for your patience.
