F9 is an error that indicates an inverter board or magnetron has failed. With the F9 error cleared, start the oven and listen for a ticking sound. The inverter will attempt to 'fire' the magnetron 5 times.(ticking sound). If can hear ticking, replace magnetron.

SOURCE: kenmore elite ultrawave microhood combination error code F9

F9 is normally a bad door switch or door switch mount.

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa.

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

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

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

This is usually inverter trouble, but it may be the magnetron, controller, wiring, etc.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

To find helpful exploded view diagrams and get part numbers, you can just enter your full model number at the Sears parts site.

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.

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"
