With a noise being made by pressing the key panal pad, that would
be a
good sign the key/touch pads are working and the problem is on the
main
control/smart board. I'd open it up ( power off first ) and remove
the
smart board and inspect front and back side of the board for any
burnt
traces first.

OK, I pulled the panel/board combination out and took it to a local
appliance repair shop. They took it in back for a few minutes and
told me
they checked it, and the board is fine; the buttons are fine. They
asked me,
"What's wrong with the microwave?". I said (pointing to the light
buttons)
that the work light and night light buttons don't work anymore (but
the fan
button, right next to those, works). They told me I'd have to bring
the
whole microwave in. Ouch! It's an over-the-range model. I don't even
know
where I'd start to try to unmount the thing from the wall.
OK, I'm out of ideas now. I know it's not the bulbs; I swapped the
good
in-oven bulb with the work light one, and the work light still didn't
come
on. I pulled out each bulb's socket and examined the connections;
they're
all solid--not loose or broken. The only thing left I can think of
would be
a wire INSIDE the plastic casing has broken...but I can't believe
that
happened. There is a plain old fuse sitting there behind the control
panel
(inside the main microwave, not part of the panel board), but it
doesn't
seem like a little work light would use such a fuse (it's about an
inch
long, 1/4 inch in diameter).
Anyone have any other ideas as to what can be knocking out my
microwave's
worklight/nightlight? Again, the buttons still beep; they just don't
do
anything. Can I just get replacement wires (they have the little
plastic
connectors soldered to their ends)? Do they need to be "official"
Sharp
wires or can I just use some Radio Shack wires? Any help is
appreciated;
thanks.

Hi,
Glad to hear the board is not burnt, but it cannot be deemed "ok"
outside of the microwave as power is needed to operate the relay(s) on
the board for the lights.
Broken or open wire between the board and sockets is possible, each
wire would have to be checked for continuity. Any "stove/range" style
wire will do fine.
The sockets can be removed and a cheater cord attached to each socket
to check the bulbs and sockets.
