F2 means you have a shorted membrane keypad.

On this model, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly 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 get it the Pros here by entering your full model number with suffix.

You can also find helpful exploded view diagrams to locate the part at that link.

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) and move the circuit board into your frame.

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

Error code F2


Per the tech sheets (page 8), "F2" error code means "Keyboard failure". Recommended by the manufacturer to replace the touch panel first and, if it would not solve the problem, then the control board has to be replaced too. Not the best recommendation but we have to follow it.

- The part number for the touch panel (aka a membrane switch) is AP3130765

- The part number for the control board AP3130764

Here are the break down diagrams for the Kitchen Aid microwave Model KHMS155LSS4

Microwave says F2 what does that mean


It is a bad keyboard error code. Try this, unplugg the unit, open the control panel and disconnect the ribbon cable from the control board, plugg back in, if F2 comes back on the board needs replacing, if it does not, then the problem is with the keypad.

Error code F2


The error code "F2" that appears on your KitchenAid microwave refers to a keyboard failure/short on the front button panel or loose keypad connector

Attempt the following to clear error:
Check keypad connector for firm connection.
Press "Cancel" after the error code is noted, if error code returns after 60 seconds, replace keypad ( also called touch pad or membrane switch ).

Best of Luck with the microwave.

What does F2 mean?


The error code F2 on your GE microwave indicates "Shorted thermal sensor", this condition will occur if a shorted thermal sensor is detected continuously over 5 seconds on convection, combination or roast cooking.
. It takes a minimum of 5 minutes of convection run time before this code will be
displayed. More information on this error code, as well as other error codes, can be found at
http://www.applianceaid.com/micro_faultcodes.html#gemicro

Best of Luck with your microwave.

My kitchenaide convection oven is displaying the E1 F4 error.


KitchenAid ovens are popular for their classic design and simple user interface. When a problem occurs in the function of a KitchenAid oven, an error code will display on the clock as soon as the malfunction registers in the oven's memory. Each code corresponds to a particular type of malfunction. Most can be corrected by disconnecting the power supply for one minute and then restarting. If the code persists, either replace the indicated part or contact a service center. F0/F1
  • The F0 and F1 codes refer to electrical issues. If the code appears as only two digits, the problem is a transistor failure, so you must replace the electronic range control (ERC). If the code displays four digits, it will read F0-E0, which indicates a failure switching from analog to digital, or F1-E1, which refers to a safety flip-flop. Both problems require the replacement of the ERC.
  • F2/F3/F4
  • The F2, F3 and F4 codes refer to problems with the oven temperature sensor or the keypad. If you see the two-digit F2 code, it means your keypad has shorted and the ERC must be replaced. The four-digit F2-E0 code means that the oven temperature is too high. Test the door lock and the relay operation, and correct as necessary. A two-digit F3 code means an open temperature sensor or thermal fuse, so those parts must be replaced. A four-digit F3-E0, F3-E1, F3-E2 or F3-E3 code or a two-digit F4 code means that either the oven is registering as too hot or the temperature sensor has shorted. Either way, the oven temperature sensor must be replaced.

    My new Whirlpool oven Model number GBD 279 PVS02 error code EO F2


    F2 E0 is a shorted keypad. Replace the keypad which is your entire touch pad. In rare cases your ERC or electronic range control can also be bad, unlikely though. Hopefully this is still under warrantee as the part alone is over 150.00. I recommend you have a technician replace this as most parts houses will not warrantee a electical part if a customer installs it. Good Luck, Appliance Specialists.

    Error code F2.Q1


    Not sure what you mean by "Q1 Touch FMEA" above, but F2 error code indicates a bad keypad or sometimes a bad sensor.

    Since it's brand new I would first consult the manual. If you don't have it still, you can download it from the owner center here: http://whirlpool.com/custserv/index.jsp

    If you still have trouble, since it's new, it should obviously be under warranty, so I'd contact them (same page as shown above) to get it repaired under warranty.
