This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

Door switches are most often damaged by opening the door while it's cooking (instead of pressing Stop / Clear first) or food
/ grease debris in the switch.

If you or a friend decide to look into it, we have critical information on safety, disassembly and door switches at our site, linked here on Fixya:

Fan on Kitchen Aid convection microwave will not shut off. the 6 speed does not appear on door.

First I'm not a Kitchen Aid tech.
* The fan is stuck on or the cook cycle has not completed. Either way something is wrong. Try unplug the Micro wave and let it rest for 10 seconds. Power back up and see if the fan still runs. If so then pull the plug. Don't use the M/W
* Check your warranty and call or take it to the service center.
* There are no customer serviced parts in a Micro wave.
*** High Voltage present. High Gauss Magnets present, High voltage storage device hazard present even with power off and disconnected! ***
* Be safe, call for service or get a new unit and dump this one.

Kenmore built in microwave - f9 error

F9 is indeed a door switch error.


I would suspect that if the switches are good, a couple of wires may be reversed on them, or maybe one of the door switch mounts is broken.


There may be a wiring diagram in the oven, either pasted to the cover, or folded and stored behind the control panel.


If you can supply the actual model number (not 636xx, etc.) I can try to find a wiring diagram.

Microwave stays on for about 15 seconds, shuts off and shows F9 as problem.

There's quite a few different makes and models out there with loads of different codes. Please tell us WHICH make AND model microwave you have and we can check the servicing guides for you.

Microwave runs for 5 seconds then shuts down displaying F9 HELP

If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the microwave display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad

Does not cook and f9 appeares on screen

We would need the full model number from the tag in or on the oven.

I would bet yours is a Kenmore / Whirlpool / Kitchenaid. If so, F9 is an inverter-related problem.

Powers off immediately after starting

My immediate reaction would be to cut your losses and buy a new unit as sooner or later you will run into a part that is no longer available.

My kenmore microwave runs for about 5 seconds and then it quits and says F-9, how do I fix this?

F9 means the main board is going into either over current or low current mode and the probable cause is magnetron problems.
I would call an engineer to give you a repair price.

A code F9 appears periodically what does that mean

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

Microwave runs for about 20 seconds then shuts off.

My mother had the same problem and she was going to trash it. Me being an extreme environmentalist, dint wanna let it go to the scrapyard. Got it down to Mumbai India checked with the engineers down here and rectified it. Problem was with the Magnatron. You would need to replace it. Well this one's getting repaired and off to a institution in need like the Home for the Aged rather than some scrapyard.
