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.

We're happy to help and we appreciate your thoughtful rating of our answer.

SOURCE: 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.)

SOURCE: Microwave turns on & control panel is frozen. F2&PAN error codes

You have a shorting membrane keypad. If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and please do not leave it running unattended.

On this model, the membrane keypad is not available as a separate part, so you would have to order the control panel frame which comes with a new keypad.

In this case, you simply move your circuit board into the new frame.

That is a simple do-it-yourself job.

You can find helpful exploded view diagrams and order parts by entering your full model number (KHMS155LWH1 without dashes) from the tag on the oven here.

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.

First, do not leave this machine plugged in until it is serviced. If this is a KHMS155LSS, there is a very high probability that you have a keypad short. This defect can cause the machine to start on its own at ANYTIME; while you are on vacation or at work or at night while you are sleeping etc. Contact Whirlpool Customer Service and ask for Safety Dept immediately. They will most likely send A&E (Sears) out to fix it. Although they will fix the problem, if the keypad fails again, the underlying logic self start defect is still present. You should be under warranty if it is above model. Please be polite, insistent, but polite. With KitchenAid's pathetic quality in recent years, their customer service reps get more then an earful. Also, please go to the Consumer Product Safety Commision website at www.cpsc.gov and post a Report Unsafe Products report. This will help get this model recalled before someone loses their home or life. I almost had a fire this past Monday, Labor Day, 9/7/09 when my machine self started at 3 AM with a package of bacon left in it to thaw at room temp for the morning. What a smokey mess. Chinese made garbage. Shame on Whirlpool. Long live Hobart!, please buy back KitchenAid and bring back the lost quality.

SOURCE: my kitchenaid microwave/convection oven shows "DOOR" on display

This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

Even though a door switch clicks, it may still be bad inside.


Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If the switch mount is broken, it's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

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

If you only need a switch, you can order a universal type here for $5 postpaid.

Kitchenaid microwave runs for a few seconds and then shows error code F7. Kitchenaid Phone Center never heard of this error.


Hi alykat737,

This error code F7 on KitchenAid microwave is about a function key that is stuck on ERC. You will have to Replace control board (also called ERC or clock) to fix the problem. In case you will have to buy a replacement part you may contact Sears for the replacement part at 1-800-252-1698; M-F 6:30 AM-10:30 PM - Sat 7:00 AM-9:30 PM - Sun 7:30 AM-9:30 PM - All times Central.

I am getting an F7 error message frim my KHHS179lWH-2. Any ideas?


For model KHHS179LWH2, from the tech sheet located behind the controls or found online here:

F7 Power to magnetron interrupted

1. Unplug microwave oven or disconnect power.
2. After 40 seconds, check to see whether this solves the problem. (Possible
reason: Over temperature protection for the magnetron opened.)
3. See safety info here, then check resistance of the magnetron thermostat. It should be close to 0 ohms.
4. Check the magnetron.
5. Check wiring to the 1100W inverter and control system.
6. Check operation of all interlock switches.
7. If switches operate correctly:
- Replace 1100W inverter.
- If problem persists, replace power supply board.
8. Plug in microwave oven or reconnect power.

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.

You have a faulty keypad. You could probably special order this part from a local appliance parts supply store for 50-60$ or purchase a new microwave.

Error Code


F7 problems are usually caused by poor connections. I suggest to unplug the ribbon connector off the control board and cleaned the copper connectors using alcohol or with a pencil eraser. If that does not work the touch pad may be defective.
