Question about KitchenAid KCMS2055SSS Microwave Oven
After re-setting clock on m/w, the cooking timer now runs at about 10X speed & magnetron doesn't seem to come on. Timer runs regardless of how cooktime is selected (add a minute, key time, or pre-sets). This unit is 22 months old. Worked fine until I re-set the clock! Haven't powered it off yet since it's a wall mount & haven't taken trim kit off to get to power plug.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Sounds like a classic bad door switch or switch holder. If you or a friend decide to work on it, we have *critical* safety info, info on door switch testing and replacement, and oven disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your base model number (without the suffix) here: http://tinyurl.com/gv383

Those symptoms are what I would expect when the controller or keypad gets wet. Tipping it is not an issue, unless that allowed the water to run into the controls more than just the wet soapy washcloth did. You may get lucky - it may dry out by itself in a few days. If not, and if careful targeting drying doesn't fix it, it will need a new keypad or controller.

F2 on a newer Whirlpool / Kitchenaid microwaves means you have a shorted 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.
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 repair for you, we do that for $39.95 plus part costs.
But please note that for some models, 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.
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.
Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

The F2 code is a keyboard failure. Since it's intermittent I would check for a loose wire/connection. open the control panel and reset the ribbon cable on the circuit board....

The magnetron may have either failed or
is not being supplied with the extremely high voltage required to run
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.
