Kenmore microwave oven model # 721 63684300 built 5/2003. Does not heat, after 25-30 sec. F9 appears on keypad. Everything else works---timer, clock, lights, horizontal turnstyle.

I checked the owners manual and it does not list the fault codes. Manufactures leave this information out of the manual most of the time so you have to call them for service.

Call 1-800-4-my-home (sears) and tell them the problem. You will also need to provide the m# so have that ready when you call.

Good Luck

Hit the start button and runs for 6 sec then code F-9 can't find manual

You didn't mention your brand or model, but F9 code on an LG sometimes means either a bad door switch or a loose door switch mount.

See this file on door switches.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

Here is more info on F9 as it relates to some brands and models:

Sears Kenmore Whierlpool 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 proceedures. 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."

I have a Kenmore Elite Mod 721.63683300. At first I would occasionally get an F9 error once every 5 or 6 times I would use it. Now, I no longer get an F9 error, but power is reduced to about 50% as...

No, the magnetron gets its power from the inverter assembly. The actual issue here is a defective or damaged inverter. Replacing the inverter assembly will correct this issue.

Kenmore Microwave Oven Sudden Power Reduction

I would be sure to check the microwave's outlet under a load.

One good way is to use a toaster or hair dryer for about a minute to see if they run at full power and run without their heating elements dimming.

If the power at the outlet is steady, I would suggest a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If it still fails to heat properly, I would say you have a failing magnetron, and it would just be a coincidence that the failure began after the new wiring was installed.

If you need to order the magnetron, Sears sells it for $73.13, but you can get it for $41.84 here.

Microwave will turn off a few seconds after start.-

It seems there is something wrong either with the builtin controls or the buttons. It needs to be examine by a professional.

Kenmore elite ultrawave microhood combination error code F9

F9 is normally a bad door switch or door switch mount.

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa.

You can probably find exploded views and order parts by entering your model number here at the Sears parts site.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

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.

To find helpful exploded view diagrams and get part numbers, you can just enter your full model number at the Sears parts site.
