MY KITCHENAIDE MODEL KHMS155LSS-4 TURNS ON & LOCKS ITSElF

You have a shorting membrane keypad.

NOTE: 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 at least leave the door open when it's not in use, and of course one should never leave a microwave unattended while cooking.

On this model (KHMS155LSS3), the membrane keypad comes on the complete control panel frame assembly.

In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.

It is part number 8205018 and you can get it from the Pros here for $108.80.

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

Then you unplug the keypad (as per the photo below) and move the circuit board into your frame.



Some connectors on the relays may have a lock:

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.

HI. the key pad, or touch pad board has failed. I recommended replacing this damaged key pad asap. this will correct this issue.

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.

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, at night, while you are away, at work etc. Contact Whirlpool Customer Service and ask for Safety Dept immediately. They will most likely send A&E out to fix it. Although it will fix the problem, if the keypad fails again, the self start logic defect is still present. You should be under warranty if it is above model. 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 to thaw for the morning. What a somey mess. Chinese made garbage.

beeps and i get an f2 code

Dougmcduff have you resolved this problem with you kitchenaid microwave turning on periodically??? I have the exact same problem. Any solutions? I called Kitchaide and no help there.

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.
