F-9 Error code

After I start my Kenmore Elite Ultra Wave Microwave Hood Combination, an error code of F-9 appears in the display of the control panel. Based on my research, I purchased a new PCB Assembly, part #6871W0S001A, and attempted to repair the microwave. How do I install this part? Are there any diagrams of how to install this part? Your help is greatly appreciated.

The F9 error code indicates a failed inverter. If resetting the unit does not help you will need to have the inverter & harness checked.

This can sometimes by caused by a power surge or glitch through the electrical lines.
You can sometimes clear this fault by completely unplugging the microwave for 1 minute.
Plug it back in and see if the fault code returns.
If it does, then you have an internal component failure that will need to be serviced by a technician.
Microwaves must be serviced by technicians due to the inherent dangers involved in repairing these appliances.
Internal capacitors can retain a lethal electrical charge even though the unit is completely unplugged.
A microwave radiation leakage test must be performed on the unit following any internal component repair.

It does not ALWAYS indicate a inverter control board problem however in other brands/models.
LG's service manual (for an example) suggests the f-9 code could be due to line voltage, magnetron, inverter module, "Relay2", or a loose connection between door/magnetron/control pcb.
Other indications might help narrow down these choices before having to pull out your multimeter and crack open the microwave case.
For example, if the microwave works, but heats slowly, then the troubleshooting manual narrows your choices down to magnetron or line voltage problems, and pretty much rules out the other possibilities.

Have a TE code showing on my kenmore elite microwave hood combo


At some place I saw that the TE error refers to the touch panel.
If you go to http://www.searspartsdirect.com/ and enter your full model number you can get parts list and buy parts and even get repair advice.
Link below shows how to replace a control panel on some model of microwave oven. In the video you will see a ribbon cable being removed. You might want to wipe the contacts of the ribbon with alcohol and put it back in to see if it helps with your problem.

Twice my new kenmore microwave has just started beeping with the error code E11 appearing on the screen.Have to unplug it to stop it. WHat is going on?


I think this microwave oven uses an inverter to control the power output of the magnetron. Usually the microwave will advertise this feature with a trade name like "accu-wave" or "true-power" or some similar label on the front of the microwave. Assuming that is the case here, then the E11 error means a bad inverter

My Kenmore Elite Ultra Wave Technology microwave is displaying an F-9 error. What does that mean?


Here are a couple of quotes from another forum:

"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."

"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."

Note that part numbers mentioned may not for your model.

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

BUT once you have the part number from the Sears parts site, you can often get the parts cheaper here

9Fp and microwave cuts off


F-9 means the inverter board has failed. A bad magnatron can also cause this code. Recommend replace the Mag. and inverter board.

F9 code can mean something different depending upon the particular model.....
1.) IF your Microwave uses "UltraWave technology"/"SmartWave technology"...Then either the Magnetron has failed or the Inverter board has failed OR maybe the control board has failed (HUH?).
2.) IF your Microwave does NOT use "UltraWave technology"/"SmartWave technology" then one or more of the door switches has failed.

** "UltraWave technology"/"SmartWave technology" **
I'll explain a few things about this wonderful technology...
The control board (accepts the pushbutton commands) has to talk to the inverter board to tell it how much power should be applied to the magnetron. The inverter board will then power the magnetron and inform the control board if the magnetron is working OK.
If there is something wrong with the magnetron or inverter board or a there is a communication breakdown between the control board and the inverter board...WA-LA-----F9----

A pretty reliable test for the Magnetron is to operate the oven and listen for a ticking sound 5-6 times about a second apart. If you can hear the ticking....The magnetron has failed..if no ticking, the control or inverter board failed.

Note: This 'technology' may come in other flavors as well
