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.

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 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.

MICROWAVE WILL NOT HEAT. F9 APPEARS IN THE DISPLAY WINDOW


F9 indicates a problem with the door latch.  There is a safety switch that will not allow the microwave to operate if it detects the door is not closed properly.  Even though physically it may seem the door is shut, the safety switch is not relaying the message to the onboard computer.  You need another door latch switch.

Humming sound, F9 and dead


Seems like I answered this, but maybe it's a different poster.

The 721 model code means it's an LG/Goldstar-made oven and F9 indicates a problem with the inverter or magnetron.

Due to the lethal voltages involved, I do not recommend that a person without training and experience ever work on these models.

I would suggest you contact Sears for service.

We're happy to help you and we'd appreciate your thoughtful rating of our answer.

F9 error code


F9 is caused by either a bad door switch, a loose door switch mount.

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

This can be caused by slamming the door or by habitually opening the door while it's cooking without hitting the Stop pad first.
