-F6- is on the keypad and nothing works

Open and close the door a few times, it's a switch relay saying the door isn't closing right.

Mine had the same code appear after running the oven which had not been used in 3 months. It heated up the food OK but then would not shutoff correctly. Still sounded like something was running after closing the door after removing the food. I opened the door again to stop it and noticed that F6 appeared on the screen and touching the keys on the touch pad would do nothing and with the door closed I could hear something humming, trying to run like the motor. I unplugged the oven and plugged it back in after a short time. Still did the same thing. I unplugged it again for a couple of hours and tried it again and it was OK. I think maybe it was a stuck door switch or relay. not sure but it is fixed. The house had been left for the winter in the low 50's so it was warming up at the time, this may have affected it also. Hope this helps someone like the above write ups helped me

Same thing happened to me tonite. First, when the microwave was done heating the food, the noise it makes to signal it was done was odd, and then there was the humming noise, which turned out to be the thing that drives the microwave plate to go around...it was going around still after the heating time was up. I eventually put 11 seconds on the timer and let it cycle (run) those 11 seconds, and then everything was back to normal. I live in an apt. building, so I guess I'll call maint. and see if anyone else has had similar problems. I was glad I'd gotten it to stop, as I doubt I'd have gotten anyone to come and check it out at 3:00 a.m.!

I had the F6 code on my Kenmore 665.61601100 microwave. I opened the door and unplugged it. When I plugged it back in I reset the time and it works……….for now

I had the same problem. Microwave motor starting buzzing when I close the door and F6 error on my Kitchenaid over stove. I unplugged it overnight but it still did not work. I read about slamming the door, which I did several times, (cheaper than making a service call). It eventually worked. No news on how long this will last but keeping fingers crossed. Adding sledge hammer back to my appliance repair bag, just in case I encounter a similar problem in the future.

Same thing here with a Kitchenaid KHMC1857BSS-1. Humming loud when door is closed. Open door and humming stops. Humming seemed like it was causing the unit to get warm. Hence I Opened door and then unplugged. Sat unplugged for hours. Did not change when plugged back in and tried. Followed the slamming of the door “trick” over and over and then voila it worked. Still a little nervous. What if it starts doing it again when no one is home? For now ok. Do I need to replace the control board? $150 isn’t bad - but finding someone to do it. Anyone else have it come back or replace their PCB ? Please advise.

I’ve had the same thing happen. See the Interior and ventilation diagram on https://www.searspartsdirect.com/model/2... site. The switches #10 ride on a cam #12 and are not lubricated and eventually wear to the point they don't close the switch properly. Slamming sometimes can finish the closure action, but is a short lived solution.

I fixed it before by adjusting the switch position and lubricating the cam surface. There are 3 switches between the upper and lower latches that can do this. The fix has lasted over 5 years on the switches I did. Back at it again though.

Update: I just finished troubleshooting the problem. This time it is a relay that has arc’d closed. Banging them may open them up, but is short lived solution too. There is not an arc suppression cap across the contacts in the design. The relay is in position 4903 and is part number OMIF-S-124LM for those electronically capable. The part is obsolete as of this date, so eBay is your best bet.
