The microwave doesn't come on and when you push


I'm assuming this is model number MH2175XSQ1.

F6 means the cook power relay on the control circuit board is intermittently shorting.

We regularly repair these controllers nationwide by mail for $39.95 postpaid with a one year guarantee. Details are here.

Or you can order a new control board ("microcomputer" part number W10166798) here for $74.30 plus shipping.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you unplug the keypad (as per the photo below), take out the defective board and install the new one.

I replaced the light bulb, now it displays -F6- and pushing any button causes a humming noise.


I left the unit unplugged over night, plugged it back in the next day and still had the same problem.

What does -F6- code stand for?


F6 means a problem in the control circuit board.
Try unplugging the microwave with the door open, then plug it back.
Try the solution that you find here, if it does not work the panel must be replaced.

I have have a 10 year old Kenmore Hood/Microwave combo built by Whirpool. I'm getting an F6 error code. What is the error code trying to tell me?


F6 —Microwave Relay Failure: Check the microwave relay.

The F6 error code which is flashing on your microwave refers to a faulty relay. However, I would suggest that you first try to run a diagnostic (which you may not be able to, but it is beneficial if it works). Here is how:

The microwave oven may be provided with a self diagnostic routine that can be operated through the touch pad keyboard. To enter the self-diagnostic routine:
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.

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.
If you want to try to fix it your self, Always remember Electricity is dangerous and should be treated with respect.
Microwaves are very dangerous, they can still shock you even unplugged!!
Use a metal ( not the shiny chrome type ) screw driver with a insulated handle to short across ( touch both at the same time ) the terminals of the high voltage capacitor to discharge it. With the microwave unplugged.

Hope that helps.........

Error code


F6 is a communication error. It is either a loose connection to the control board, or the control board is shot. They should have diagnosed this when they came out to fix it. Open it up, and look for loose connections.
good luck

Kenmore Microwave hood combo Model # 66569689992 F6 error code?


i fixed by unplugging the microwave with the door open. I plugged it back in and the F6 was gone. I was then able to set the clock and turn the light on/off . When I closed the microwave door, the F6 came back on and the microwave was making a humming noise. I slapped the side of the microwave near the keypad, and the F6 cleared from the readout and the humming stopped. The microwave is working fine now. Don't know why, except maybe slap on the side reset a relay or something. Anyway, I will never by a Sears Kenmore appliance for the rest of my life. The door rattles when you open a close it (like a part inside the door is broken) and this is the second time a fault code has appeared during use. I had GE Profile appliances at my last house, which are more $$ initial cost, but who wants to screw around buying a new microwave every four or five years. I'll happily spend a couple hundred more for the peace of mind and knowing that it will work during Thanksgiving dinner with the family over.

Microwave won't work


F6 usually means a fault in the controller or keypad. You could try to unplug it for several minutes, then plug it back in. If it still fails, maybe you or a friend can disconnect the power cord, unplug the keypad strip internally, then plug the power cord back in and try it with the keypad still disconnected. If it does not fail again, you have a wet or shorted keypad and can dry it or order one. If it does fail again, the control board is bad. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your full model number (without the suffix) here: http://tinyurl.com/gv383 Sorry I didn't get to answer this before the bogus answer was posted. I've been tied up and away from the PC.
