SOURCE: I have a Kitchenaid Microwave

F2 on a Kitchenaid microwave means you have a shorted keypad.

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.

SOURCE: Kitchenaid microwave oven KBMC140HSO

I started having the same problem with my KBMC140HSSO. You cannot see the error codes without disassembling the control panel (the codes are on another display that covered by the front panel). After doing so I found the error code to be F2, E3 which is "Key held down too long, or key shorted". I am ordering a replacement keypad and will report back if this fixes the problem.

SOURCE: Kitchenaide KHMS155LSS Microwave F2 apears on

"F2" means your membrane keypad is shorting.

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 of course, never leave an oven cooking unattended.

You can order the control panel frame assembly with a keypad already installed here .

You can also find handy exploded views there. Just do a search by full your model number (KHMS155LSS1, KHMS155LSS2, KHMS155LSS3, KHMS155LSS4, etc.).

You first unplug the oven and remove your control panel assembly as per the video at our site.

Then disconnect the keypad strip as per the picture below.

Then you take out the screws holding your circuit board to the old frame and put it in your new frame

Be careful, since the display is glass.

Reassembly is the reverse of disassembly.

SOURCE: microwave model KHMS155LSS-3 turns self on

I had the same problem with the same model of KitchenAid Microwave. KitchenAid customer service will act like they never heard of the problem, although if you google it, you will find that this is a very common problem. Ask to be transferred to the safety department. After more than 6 months of complaining and several repair attempts (they replaced control panel and switches), KitchenAid finally gave me a full refund. This is a serious safety defect for which they have no fix. The product needs to be recalled, and I am willing to testify that KitchenAid was criminally negligent when this product finally causes a house fire and possibly serious injury or death.

F2 means 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 of course one should never leave a microwave unattended while cooking.

This is actually a simple do-it-yourself job. You simply move your circuit board into the new frame.

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.

Next, disconnect the strip as shown in the photo below, then remove the screws that hold your circuit board in the old frame.

Then carefully (since the display is made of glass) move your circuit board to the new frame, and reassembly is the reverse of disassembly.

The part number to order is W10306627 (formerly 8205018) and you can get it here for $107.05 plus shipping.

You can also find helpful exploded view diagrams at that link.

Kitchenaid microwave model KHMS155L, starts randomly for 3 minutes with "PAN" flashing on display screen, than locks up with "F-2" message on display screen


"F2" means you have a shorting membrane keypad. The "Pan Heat" key is shorting.

On these models, 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 find helpful exploded view diagrams and order parts by entering your full model number* from the tag on the oven here.

Whirlpool is conducting a safety recall on the Kitchenaid KHMS155L series (and similar models under other brand names) that display the F2 code or have been observed self-starting. Other symptoms may be additional codes or unintelligible info being displayed, and failure to execute the command entered into the control pad. To obtain free replacement of the control panel, call Ava at Whirlpool: 1-866-640-7146, extension 6337. She will want your complete model and serial numbers and a phone number and address where you can be reached. She will arrange for A & E Factory Service to contact you to set up an appointment to come out and replace the control panel at no cost to you.

Microwave will turn on by itself and display PAN on screen.


Does everything come on by itself or is it just a fan that comes on? If so, is it a convection oven?

Microwave is beeping, lock comes on, F2, just keeps beeping by itself


F2 on a KitchenAid mike usually means a Keypad short. Beware if it is a KHMS155LSS, it can self start on its own with a KeyPad short. A real stunning defect.

F2 code on display - microwave does not heat


F2 on this model means 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 available already mounted on a new control panel frame. It runs a little more, but saves a lot of time consuming and aggravating work.

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


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 remove a few more screws and disconnect the wires.

It is part # AP3673562 (same as 8205018) and runs $80.97 + shipping here.
