Seems like I answered this, but maybe it's a different poster.
The 721 model code means it's an LG/Goldstar-made oven and F9 indicates a problem with the inverter or magnetron.
Due to the lethal voltages involved, I do not recommend that a person without training and experience ever work on these models.
I would suggest you contact Sears for service.

you must remove the MW take off the cover then look for a large metal can (capacitor) and a white (ceramic) fuse...look and, smell and, you should find the cause

You have a shorting
membrane keypad. If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.
So until it is repaired,
please leave it unplugged or leave the door
open when it's not in use, and please do not leave it running
unattended.
On this model, the membrane keypad is not
available as a separate part, so you would have to order the control
panel frame which comes with a new keypad.
In this case, you simply
move your circuit board into the new frame.
That is a simple do-it-yourself job.
You can find
helpful exploded view diagrams and order parts by entering your full
model number (KHMS155LWH1 without dashes) from the tag on the oven here.
At
our Web site, we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
