LG Microwave #LMVM1945SW, Error Code F-9

5 posts in this topic

I ran this LG microwave, model LMVM1945SW, at a home inspection yesterday. It's an over-the-range model where the tray moves left & right rather than rotates. It appeared to start & run normally but, after about 10 seconds, it shuts down and displays F-9 in the LED screen. Repeated twice.

1. What does this code indicate? Is there a fault or error code list available?

I did not find any reference here yet. A quick web search reveals many folks with the same question. Multiple answers say: magnetron, inverter, PC board, or sensor.

2. All these different answers make me wonder if the code is even reliable or whether replies were just guesses.

Thanks in advance!

Thanks Reg! You've helped me in the past too & I always appreciate the quick replies. I did verify proper voltage at the receptacle. But, I won't be working on this one since it is for a home inspection client and I'll recommend a local tech if she buys the home. Just wanted to give her & the owner some idea, if possible, how involved/costly the repair might be, based on the error code.

I'd like to review the manual though.

The Samurai has temporarily lost my lifetime permapprenticeship but promised to restore it after I re-registered today. Would it be possible to add that manual to his LG manual stash in the meantime? I still have a link to that site but can't open your link above until I get upgraded :-(

Thanks anyway...I'll come back when I get notification of reinstatement. Not sure how I'll know, but I hope he'll send me an email soon.
