I have had to shut the circuit braker to the Microwave, it repeatedly starts a cooking cycle by itself. It begins by asking for number of pieces, cycles through the options and then starts to cook by itself. It is very dangerous, ANY SOLUTIONS?
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.
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.
If not, please reply back with your brand and model number so we can help you better.
In many brands there is 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.
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
model number) for more information & help.
We're
happy to help you with free advice and we'd appreciate your thoughtful
rating of our answer.

My KA over the stove mircowave vent grille , Model KHMS155L) fell off onto the stove (luckily when burners were not on). I discovered that the vent grill is only held in place by low quality plastic brackets that were affected by the heat. Now the grill is taped into place with metalic HVAC tape. This design seems to be a safety issue. Was this a re-call, or just poor design?
My grill has also fallen off twice. It usually results in the tabs breaking off. My solution has been to add tiny (1/2" x 1") shims in the slots where the tabs have broken. Look carefully. There are two tiny channels. I wedged the wood in and then reattached the grill using sheet metal screws in the same screw holes. It won't come down again. In three years since doing the kitchen with all KA appliances we have replaced the grill once. We had the stove removed and replaced by the appliance company at no charge after 4 months. We had our ice maker replaced out of warranty. I would never recommend KA appliances to anyone. The quality is absolutely terrible.

I'd say you have a contaminated or failing keypad or possibly residue on the boar dor where the keypad connects to the board.
Is it possible that some spray cleaner got into the controls?
I always recommend that users instead spray cleaner on a soft cloth then wipe the control panel.
Also, I always recommend non-ammonia cleaners since ammonia can crack and damage plastic.
Otherwise, the spray can get into the controls and lock it up or make it act odd.
If it does not dry out over time, it may need to be manually dried or blown out.
The keypad may be damaged or worn out, or control unit may be damaged.

KitchenAid built in microwave model #KHMS155LSS-4.
My microwave keeps beeping and I am also unable to unlock the keys. What I tried to do already is unplug the unit and plug it in again. No change. Then I tried holding the Cancel key while unplugging the unit, waiting 5 secs and plugging it in again. No change.
Even when the unit was unlocked, it had started beeping.
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.

I'm replacing the Magnetron. The 2 terminals are marked 'F' and 'FA' and are reversed on the replacement unit. Checking the wiring diagram the 'F' connects to the H.V. Capacitor and 'FA' connects to H.V. Transformer. My problem is that the factory wiring on the original magetron is reversed when compared to the wiring diagram that came with the appliance. How should I connect the replacement unit - as the wiring diagram or the factory installation of the wires?
http://wiki.brandoncurtis.com/w/File:Microwave_Wiring_Diag this is a good diagram of a standard microwave. ive pretty much only seen on single mag ovens. "F" usually has a single wire from the hvtrans. "FA" is usually the gang off the cap.

I have a Kitchen Aid Microwave Model # KHMS155LSS-1. How do I romove the back panel of the door such tha i can replace the door handle.
The door handle can easily be replaced on MOST microwave ovens by removing the inner door panel that goes around the perimeter of the glass. The following link explains how to access and replace the door handle:
http://www.fixya.com/support/r3696942-microwave_oven_door_handle_replacement
The average cost for a replacement handle usually runs about $20 - $40. Replacements may be purchased at the websites listed in the link I provided.
The part number for the model number you provided varies depending on color, so make sure you order the correct one for your oven. You can view an exploded view of your microwave door here:
http://pcappliancerepair.com/model-display.php
The door handle is a simple repair that can be done with the door in place, or with the door removed. You do not have to uninstall the oven if this is an over the range model.
If you have any questions, please post back and let me know. I hope this helps you

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.

How do I unlock the key pad? The display shows locked and I don't know how it locked.
Here you go.
The Child Lock shuts down the control panel pads to prevent
unintended use of the microwave oven.
When the control is locked, only the Vent Fan and Light pads will
function.
To Lock/Unlock Control: The microwave oven and Timer must
be off. Touch and hold START for 5 seconds until 2 tones sound
and a lock icon appears on the display. Repeat to unlock and
remove the lock icon from display.

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.

MY MICROWAVE WAS WORKING PERFECTLY FOR ABOUT 10 SECONDS AND THEN THERE WAS A NOISE LIKE A GUNSHOT. MICROWAVE WILL STILL TURN ON BUT IT IS NOT HEATING. IS THIS FIXABLE?
HI. Your symptoms are a strong indication Magnetron failure. This is the principal heating device, that is used to produce microwaves that , essentially, excite the water molecules in the food, thus, producing the heating effect. When this device fails, generally, the unit will run, but not heat. This device is very fragile, and can injure you if you are not qualified to handle this type of component. There is a High Voltage Capacitor, that is used to help provide the necessary current for optimal Magnetron operation. This capacitor must be discharged correctly. If not, you could risk serious injury, during the repair, if it is accidental touched.
The Magnetron is linked to a cut-off fuse. If the magnetron becomes unstable, this fuse will shut the device down. It is standard procedure to have this fuse test for continuity. If the fuse has blown, this will be the culprit. Replace the fuse. Now, if the fuse continues to show continuity, this will confirm that the Magnetron has failed. I would advise to inspect the Capacitor, and HV diode for visible burn marks, or swollen top(Cap).
Access can be ac hived to these parts by removing the outside cabinet screws. Once the screws are removed, the cover can be removed, as well. Once the cover is removed, the internal components will be exposed for testing, and visual inspections.
WARNING: IF YOU ARE NOT A QUALIFIED SERVICE TECH, THIS WILL NOT BE A NOVICE DO IT YOURSELF JOB. MICROWAVES ARE VERY DANGEROUS, AND CAN CAUSE SERIOUS INJURY. I RECOMMEND TO CALL FOR SERVICE, IF YOU ARE UNCOMFORTABLE WITH HANDLING THE CAPACITOR, OR MAGNETRON.
