The F3 means you have a shorting membrane keypad.

If and when an oven exhibits this code or is coming on or doing anything by itself, this is very dangerous and can result in a fire.

None of us on this site recommend trying to repair this type of problem on a microwave because it can kill you. Toss it and get a new one, PLEASE.

Thank you for this advice. I was experiencing this F3 error message along with the beeps, so I would plug it in to use it and disconnect it when I was done, but after reading this information, I decided to just toss it and get a new one. It's too dangerous to chance. Thanks


Thank You for information I have 3 young kids and I have let Willow Ridge Apartments LLC know about this and they have cancel my request. I unplugged the microwave/ fan a few times and it seem ok for a couple of minutes but the acts by itself with loud beeping nonstop and signal -F3- . I have read this info and I don't feel safe to use it or try. What can I do ? Can you please


Wow, what an exaggeration. The microwave will not kill you. Just unplug it and replace the board. Cost about 150 to 200 dollars. Or you can try just cleaning the board first. A very easy fix. Look on YouTube for videos on how to replace the board.


I fixed my CODE F3 issue by re-seating the ribbon cables. These cables tend to loosen up with time. So, to fix, you need to remove cables and insert back.
