The F9 problem in this
microwave is a bad magnetron or inverter.
From other users:
"F-9
on this microwave IS inverter related. My problem was the magnatron and
checked out bad with the help of (the tech sheet). It would run for a
few seconds making clicks and then say F-9. It has been working great
since I replaced the magnatron."
"f9 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."
The
first
thing I would suggest is a hard reset. Unplug the unit for several
minutes or so. Then plug it back in, set the clock and try again.If it fails again and you or someone you
know
decide to look into it further, we have critical safety information and
disassembly information at our site, and our link is at our listing here on FixYa.
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.
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.
You can find
exploded views and order parts by entering your model number at the Sears
parts site.The magnetron probably has an extended warranty beyond the normal one year parts and labor warranty.
So I would consult your owner's manual or contact Sears for details on the warranty.
To get your owner's manual, just enter your full
model number at the Sears
parts site.
On the resulting page, look to the right for the blue "View Manuals"
button.
That Sears-related site has many free manuals. While the manuals they
list there are all free, they will ask you to register.
If yours is not listed there for free, you would have to order it
through the Sears
parts site.
