Check the door switches if one is bad it may think the door is being opened and stop the unit from running. If it is from a bad connection it will get worse as it gets hotter while running.

Just had this happen - the repair guy says it is the inverter. And they have stopped making the part so it cannot be fixed!!! When did you buy your unit?

This applies to several models:

"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."

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 site, you can often get the parts cheaper here.

Hello :

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

WARNING : A microwave is capable to give you a serious electrical shock even when it's unplugged , so I recommend you to call a repair technician for help .

good luck .

please don't forget to rate !

Look at the owner's manual of similar Kenmore models there does not seem to be a setting that allows you to turn off the turntable. However if your microwave (sorry but I couldn't find your exact model number online) has the time of carousel that has a lift out glass plate with a notch (hub) in the center of the bottom side then you effectively turn of the carousel my removing this glass plate. (see pg 4 of the manual - above link) You can place a normal microwave safe plate in the microwave in it's place. Make sure to leave the rollers in place...just remove the turntable.

Take it immediately to a local Microwave repair shop...looks like one of the circuits may have gone...otherwise switch off from mains

Please reply back with your brand and full model number so we can help you.

A full Sears/Kenmore model number usually has 3 digits, a dot, then 8 more digits, such as ###.########

My Kenmore Elite microwave (don't have the model number in front of me) also mysteriously locked its own keypad (we were sitting in an adjacent room, heard a strange beep, and got up to find the LED reading "Locked."). I pressed and held down the Stop/Clear button for ~10 seconds and it returned to normal.

Generally the F9 code indicates a problem with the door latch (usually upper) or with the control board. You can do a Google search for my text file "doorsw.txt" to help you diagnose and repair door switch trouble. BUT - since it always stops at 53 seconds, that leads me to think you have trouble with the control unit (circuit board / controller assembly). Once you read and digest the info on door switches, please feel free to do an updated post and I'll be happy to help you further. It may be corrupted ROM in the control unit. But let us know what you find out. - online they call me "William E. Miller, AS-EET"
