F 14 going off in 10 sec

F9 code is only to that model, it's not the same on all the ovens. I'd try to check the wiring make sure it's getting the power it needs if keeps going it might be burned out. Also look in the back and call the manufacturer. Good luck

Before spend $$ on replacement boards, make sure anything attached to it is powered off. Unplug TV for 5mn to 15min. Plug back in and it should power on. If not leave unplugged overnight before spending on a replacement board. We have to do this 2-3 times per year when someone forgets to turn off auxiliary components (receiver, DVD, cable box, etc) first. It has always come back on.

The buzzing you hear is the water valve trying to run water to the icemaker. If there is no water going to the icemaker it will be going into cycles one after another. And when it does it adds heat into the freezer. Turn the ice maker off and see if the freezer gets colder.

Sorry to read about your problem, I hope this helps you out.

I had a similar problem--no manual--but found this way to set the clock:
1) Be sure colon is flashing (unplug and replug)
2) Press the 10 HOUR/MIN, 1 MIN, 10 SEC/MIN, and 1 SEC/MIN buttons until the correct time displays.
3) Press the CLOCK button.
Hope this helps.

Assuming yours is a model KHMS2050SSS0, here is what the technical sheet says about the F7 error code:

1. Unplug microwave oven or disconnect power.
2. After 40 seconds, check to see whether this solves the problem.
3. Unplug microwave oven or disconnect power.
4. Check cooling fan operation
5. Check the magnetron.
6. Check P65 connection on the relay control board.
7. Check the P56/P66 connection between relay board and relay control board.
8. Check wiring to the 1200W inverter and control system. See “Checking Inverters.”
9. Check operation of all interlock switches.
10. Replace all parts and panels before operating.
11. Plug in microwave oven or reconnect power.
12. Check voltage at 4903-1 on relay board. If it is 120, unplug microwave oven or disconnect power.

(This troubleshooting guide presumes one does not know how to test electronic components. That's why they say to replace and part and check it again.)

If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor.

Went to the store where I bought it, and talked with a sales rep. in the appliance dept.
After paying $ 198 for the microwave and...$ 159 to have it installed, I was not about giving $ 9.99 more to answer a simple question.

Sounds like the control board has gone bad and will need to be replaced.

if you are not a tech kindly take your microwave to a tech for repairs.the diodes or the cap high voltage is your culprit.good luck.
