Open Question

7 Keypad Buttons Don't work on KitchenAid KCMC 155JSS combo oven

Several of the most often used buttons, and a few rarely used, no longer work on the control panel of my KitchenAid countertop combo microwave/convection oven. Those NOT working are:
Start
Cancel/Off
Fish
0
3
Custom Defrost
Cook

We can only operate the oven using Auto Sensor Controls for REHEAT & POPCORN, since the other working buttons require you to push the Start button to activate, and the Start button will not work.

Model # KCMC 155JSS-0
Serial # FGP 3102279
1000W Made in July 2003

I would be willing to remove the control panel to investigate or repair.

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

I'm guessing the model number would be KEMS308GSS0.

In some cases, this is a glitch that can be cured by unplugging it for 1 minutes, then resetting the clock.

In other case, it may be a bad keypad (membrane switch) or control board.

Please feel free to contact me directly if you need more help.

We're happy to help and we appreciate your thoughtful rating of our answer.

SOURCE: Microwave/Convection Oven has mind of its own: turns to Crisp mode on its own.

Yes this is a touchpad issue. As you have noted the crisp button is stuck and this is the cause of this. You can try removing the keypad and push up the pressed button. If its jammed then replacing it is the only way.

SOURCE: KitchenAid Superba Microwave/Oven, Microway Door message

This is usually caused by either a bad door switch, a loose door switch mount (which are pretty simple problems to fix) or occasionally a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

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

There may 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 only need a switch, you can order one from us for $5 postpaid.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

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

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; while you are on vacation or at work or at night while you are sleeping etc. Contact Whirlpool Customer Service and ask for Safety Dept immediately. They will most likely send A&E (Sears) out to fix it. Although they will fix the problem, if the keypad fails again, the underlying logic self start defect is still present. You should be under warranty if it is above model. Please be polite, insistent, but polite. With KitchenAid's pathetic quality in recent years, their customer service reps get more then an earful. Also, please go to the Consumer Product Safety Commision website at www.cpsc.gov and post a Report Unsafe Products report. This will help get this model recalled before someone loses their home or life. 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 it to thaw at room temp for the morning. What a smokey mess. Chinese made garbage. Shame on Whirlpool. Long live Hobart!, please buy back KitchenAid and bring back the lost quality.

Touchpad and Control Panel If the microwave buttons don't work the touchpad and control panel assembly are probably defective.

Touchpad If the microwave buttons don't work the touchpad might be at fault. Generally speaking, if the display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.

User Control and Display Board If the microwave buttons don't work the main control board is most likely defective and will need to be replaced.

Main Control Board If the microwave buttons don't work the main control board is most likely defective and will need to be replaced.

Only a few buttons on my key panel work, example the start/ clear button does not work, a few numbers do work. I think its from condensation. How can I dry this out? Can I use a hair dryer?


Yes you can use a hair dryer but the power should be off so that you don't short it out any more than it already is. Most likely the keypad has been ruined and will need replaced., Once these go bad there is no fix except to replace the keypad.

The Keypad is a Circuit.Each of the Function Buttons is a switch. The same "Touch" Techinology as is used of your TV Remote Control Pad or your Telephone. It would appear that your Keypad Circuit is Open, not allowing touch commands to reach the Control Board.The Keypad will have to be replaced. Best done by a Professional. I have seen "Rare" cases of a defective Door Switch causing such symptoms.
