Microwave quits after 6 seconds and displays f-9

bethvaughn · 12-06-2007, 05:31 PM

This is a Kenmore elite ultra wave microwave hood combo. It starts runs for around 5 seconds and then beeps and displays f-9. It will not heat and unplugging it for 40 seconds doesn't work (someone elses suggestion) Anyone have any idea what's wrong? Also for the 6 seconds it's on it makes a clicking noise about once per second?

Hi Beth -

I have the same problem. Did you successfully solve the problem either within this forum or other contacts?

Thanks, ChuckM

I now have the same problem. It started Christmas night.

Any ideas?

Thanks

I, too, have just had this happen. The clicks and f9 message. I hope someone finds the answer!!

The F9 message is the inverter PCB board that has gone bad.

It is part number 6871W1so19A : Most people will need a technician to replace it.

This is for the model # 72163683300

Herbie,

Thanks so much for the reply. I was beginning to think noone knew. Thanks for fixing all our problems.

I am having the same problem and it just started happening today. Mine is a Kenmore Elite Model # 407KM00623 purchased in 2004.

I find it interesting that all instances that I have seen on google (and here) have happened within the last 45 days. I wonder if this is an internal software problem.

Sorry - that model# should read: 721.80883400

"runs" (and clicks) for about 5-10 seconds (but does not cook)

And then craps out and flashes F-9

Nice for an 800 plus dollar machine that is 4 years old.

The Sears parts Web site is down for nightly maintenance as I write this, but every other manufacturer indicates that F9 is a door latch (switch) problem, not an inverter problem. Unless I'm on the wrong planet all of a sudden.

So, I would suggest that you all check (or have a friend check) the door switches and mounts.

You can find handy files on safety, disassembly and door switch diagnosis and replacement if you look at my user name and come find me.

Always happy to help.
