Does the digital display light up at all? Is it completely dead? Are you sure it has power? Have you tried another outlet? If the outlet is good and the unit is completely dead, the internal fuse may have blown. You can try to take the cover off (with the unit unplugged) and look for a blown fuse. Try replacing the fuse with an EXACT fuse of the same rating. Try plugging the unit back in again and see if the unit comes back on. If not, you may have a power supply issue or defective Magnetron.
Please let me know what you find and we'll go from there.
Good Luck,

Quoting another board:
Sears Kenmore Whirlpool LG 721.63683300. F-9
on this microwave IS inverter related.
There is a service tech
troubleshooting document stuffed in behind the control board cover
which has some testing procedures. My problem was the magnatron and
checked out bad with the help of this document. It would run for a few
seconds making clicks and then say F-9. It has been working great since
I replaced the magnatron PN 6324w1a002c.
f9 model 721.63764300
Kenmore
Elite 36 " over tne counter microwave is supplied by LG made by Gold
Star, made in China. It's main problem is the high voltage inverter
board supplyed by Sears Parts. If you get a F-9 code on your microwave
display screen and the micro quits it's probably this board. Reset the
machine by pulling the power plug and waiting an hour. If it is the
high voltage board is at fault it will probably fail after 45 seconds
of start up. This part is really hard to get at but is less than $100.
A qualified technician should be able to remove and repair this item in
less than hour. Some techs will quote you $300 labor, don't buy it, it
should cost a $100 or less. No need to buy another microwave.

This is usually inverter trouble, but it may be the magnetron, controller, wiring, etc.
There
should be a "mini-manual" (tech sheet) hidden inside the unit
behind the
control panel or hidden on the left side behind the grille, which is
very helpful when troubleshooting, testing, and locating components.
