Replace the inverter board and use a qualified microwave engineer. There are extremely dangerous voltages in here!

Found this posted under Whirlpool instead of Sharp, but I'll be happy to answer it here.

While that one may not be available, we have one that may be close enough to work:

I'm guessing the model number would be KEMS308GSS0.

In some cases, this is a glitch that can be cured by unplugging it for 1 minutes, then resetting the clock.

In other case, it may be a bad keypad (membrane switch) or control board.

Please feel free to contact me directly if you need more help.

Hello, please use the chart to determine which stove you have. You will have to look at the model number. The first 3 numbers will be the series on the chart. In most cases an F1 error would require replacement of the electronic control. This part is commonly refered to as an EOC or ERC. However this type of repair is usually reserved for repair specialists.

KENMORE Range/Stove/Oven Fault Codes – 362 Series (General Electric)
F1 = Stuck Touch Pad Key - Replace Electronic Range Control (ERC).

KENMORE - 911 Series (General Electric/Roper)
F0-F1-FF = Failed transistor in Electronic Range Control (ERC).

KENMORE Range/Stove/Oven Fault Codes- 665 Series (Whirlpool)
F1-E0 EPROM Error - Electronic Range Control (ERC).
F1-E1 EPROM Error - Electronic Range Control (ERC).
F1-E2 U/L ERC Errors - Electronic Range Control (ERC).

What is Error F7


I am having the same problem. According to the owner's repair guide error Code F7 indicates that power to the magnetron was interrupted. You will want to make the following checks: 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 resistance of the magnetron thermostat. 5. Check the magnetron. 6. Check wiring to the 1100W inverter and control system. See "Checking Inverters." 7. Plug in microwave oven or reconnect power. 8. Check operation of all interlock switches. Check door, hinge and cavity front alignment. Adjust as needed. 9. Unplug microwave oven or disconnect power. 10. If switches operate correctly, replace 1100W inverter. 11. If problem persists, replace electronic control. 12. Plug in microwave oven or reconnect power.

While this is helpful, it is still out of my confort zone as I pulled the control panel and discovered a virtual zoo of connectors. Obviously ponly a trained repairman knows which ones need to be checked. I will probably have to resort to calling one and shelling out the dough.

Works for approx 30 secs then it cuts off with a error Code F7 message.


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.
13. Replace inverter.
14. Replace all parts and panels before operating.
15. Plug in microwave oven or reconnect power.
16. If problem persists, unplug microwave oven or disconnect power.
17. Replace relay control board.
18. Replace all parts and panels before operating.
19. Plug in microwave oven or reconnect power.
20. If problem persists, unplug microwave oven or disconnect power.
21. Check for reversed plug connection on controls or loose wiring.
22. Replace all parts and panels before operating.
23. Plug in microwave oven or reconnect 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.)

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

If yours is a different model number, please reply back.

Code F6


That's usually failure of a relay on the control board.

There should be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

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

We regularly repair these control units for customers nationwide by mail for $39.95 postpaid in about a week.

Feel free to contact me directly (and please remind me of your model number) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
