Try pushing the off/cancel button. It may be that your microwave somehow got into the test mode for the key pad.

The "lock" function is nice if you have kids who like to push buttons. It disables the microwave oven to prevent it from running unnecessarily,
To disable the lock feature push the "STOP-CLEAR" button. Then press and hold the "START" button until 'locked' is no longer shown on the display panel.
To re-lock it, do the same thing until 'locked' appears on the display.
Have a nice day.

Get rid of your microwave. Studies have shown that microwaves change the molecular structure of the food, causing abnormal qualities and cancer. The inventor of the microwave doesn't use one.

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

If the junction box in inside the microwave , refer it to an authorised Kenmore agent for examination and possible free repair/replacement.
If it is and external junction box, call a qualified electrician as the contacts were not maintained and kept tight.

A bad inverter is usually the cause of this code...try to unplug the unit and then plug it back in... if that don't work then you will need to have it checked...

The F9 code 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.

The F-9 error code indicates a defective control board, inverter or line voltage too high

raymond_anta, can you please tell me how to solved getting to the bottom screw?

Kenmore 63662 /... | Answered on Nov 03, 2010

If the model number is correct, you need to press and hold the START button down until the lock icon disappears (roughly 4 seconds). The same procedure is used to lock the panel. This is a designed safety feature to prevent children from manipulating the controls.

These instructions are printed on page 12 of the owner's manual. If you no longer have a manual, you can obtain a replacement copy at managemylife.com. Just enter your model number under the "Manuals" link and your manual is available in .pdf format that you can download or print for FREE.

F 11 code. it is a touch pad error.
If you just cleaned the control panel it may have water in the panel causing a key to stick.
If after a day or 2 it hasn't dried out - then you will need to replace the touch pad.

Visit www.searspartsdirect.com and enter in your full model number for a parts breakdown and schematics.
