The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

Let us know if the hard reset does not fix it.

Chances are you have a failed keypad.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

You can usually 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.

If you would like to have us do this for you, we do that for $39.95 plus part costs.

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

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

Code f 7


There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components. It should cover an F7 error code.

A video is available here showing how to remove a typical over the range control panel assembly in under 5 minutes.

This may help:

F7 Error Code On Microwave Ovens With Inverter Board
MODELS: GH9177XL, GH9185XL, MH9180XL, MH7155XMS, & KHHS178L for example

An F7 error code could be an inverter board failure. Anything else that prevents microwave energy may also cause an F7 error, and must be checked. The technician should perform the following procedure to test for an F7 error code:

1. Check the magnetron.
2. Check the magnetron TCO (it should be closed).
3. Check the 3 interlock switches.
4. Check the harness wiring.
5. Check the electronic controls.
6. Check the inverter board.

I recommend that you bookmark that link to your favorites.

There is a technical sheet inside the unit.

On it you'll find help locating components and a chart which shows the "F" codes. F7 is likely either a door code or an inverter failure.

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.

Hope this helps.

Thank you for using FixYa.

Code F6, E0, "Communication Error"


Hi. this code represents a key pad or control board malfunction. you will have to make sure the key pad or control panel connectors are connected tightly and securely. If the wires and connectors are secure, the actual control board may be faulty and you will need to replace it at this point.

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.
