-F6- is on the keypad and nothing works

My Kenmore Microwave model # 665.68681891 just stopped working and has an -F6- code on the keypad. The motor sounds like it is humming and trying to start when I close the door. I flipped the breaker but it didn't help.

Rachel Beaver your 665 model number prefix means that it is made by Whirlpool. the Whirlpool error codes list F6 as a failure of the door switches. You could see if it works by gently lifting up and alternately pushing down on the door / handle. I believe the Whirlpool also has a diagnostics mode. You can enter it by:

"1.While pressing the CANCEL keypad:

a) Open the oven door.

b) Unplug the microwave oven for 2-seconds and plug it back in.

c) Release the CANCEL keypad and close the oven door. You will see the following display.

CHART

NOTE: The humidity sensor test results will appear on the display after 8-seconds.If the tests are successful, "OK " will be displayed. If one or more of the tests fail, "ERR " will be displayed.. 2.When a keypad is pressed, a number according to the test chart will be displayed. When no keypad is pressed, a blank "—" is displayed."

The sears manual refers to F6 error as a F6 —Microwave Relay Failure, which would explain why the motor is "humming" The relay is part of the PCB and may require you to get a new PCB. Again, try the diagnostics and see what it tells you. Whatever the cause may be, I strongly recommend that you get a qualified person to repair your microwave. Those things can kill you and are not really a good project for the DIY'er unless experienced with microwaves. Microwaves are very dangerous, they can still shock you even unplugged. Here is a site with great info. Hope this helps, good luck.

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.!
