You probably have a failed membrane 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 find helpful exploded view diagrams and order parts by entering your full model number here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

If you would like to have us do this repair for you, we do that for $39.95 plus part costs nationwide.

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 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.

Either way, we can let you know what your options and costs would be and send you other helpful info.

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.

Microwave Oven Control Panel Repair Nationwide

Maybe try a cookbook? ;-)

Seriously, the best way to make cakes in a microwave oven is to use the convection setting only.

Your user manual will tell you how to select this open.

your problem is more then likely the fuse, but the fuse holder is most likely bad as well

It's not unusual for there to be some smoke and smell the first few times you use it.

Try it a few times and see if it lessens each time.

If so, then you're probably okay. If not, then it needs to be checked.

This should all be covered in your service manual.

If for some reason you don't have yours, you may be able to download the installation instructions from the Sears parts site.

Just enter your full model number there.

A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########

On the resulting page, look to the right for the blue "View manuals" button. Click there.



That Sears-related site has many free manuals. While the manuals they list there are all free, they may ask you to register.

Oven-safe glass or ceramic dish will be fine.

I do not have a service manual since it is not a free PDF, but looking at a like model, this is clearly a control board issue

Doors for microwave ovens are usually replaced as a complete item. I would ask the person who forgot to fix the door latches properly back to fix it properly. If some of the clips were snapped off when removing the door panel, the panel must be replaced or it will fall out again.

I am a bit late on this question, but just ended up in a rabbit hole of unanswered Kitchenaid questions The self cleaning features only serves to keep manufacturers in steady sales of parts. Quite simply the oven can only take those temperatures a few times until they break. The heat burns out elements, damages fans, door locks and worst of all damages control boards which are not far enough from the heat source. You problem sounds like the walls of the oven have buckled in the heat so the racks no longer fit. Too late now, but you should have taken Kitchenaid to court, the oven was not fit for purpose under the description they used to sell it to you. Never use the self cleaning feature as stated here https://www.google.com/search?q=self-cleaning+oven+temperature Never Ever use the self clean feature. We see damage here every couple of weeks. The worst was a burned control board on an oven that all parts were obsolete, so the self clean cost a thousand bucks! Self-cleaning ovens bring the heat so you don't have to spend hours scrubbing. Traditional self-cleaning cycles heat the oven between 800°F and 900°F, helping turn soil and spills to a powdery ash you can then wipe away. They utilize only heat-no chemicals-and are built to withstand high temperatures. (Says Maytag who love selling elements, door locks and other parts),

There is a huge capacitor inside microwaves, and that description sounds like it is starting to fail. There are smaller capacitors as well. It won't be a door switch, they work or they don't. I had two Panasonic Commercial microwaves in a pub kitchen, one plain and one was a combination machine and both had drop down doors.

I'm not familiar with that particular model, but with many of their models (and many other manufacturer models as well), unfortunately the beep cannot be turned off.

Question moved from Cars and Trucks category. No wiring schematic exists, but this does show there is an internal fuse. https://www.repairclinic.com/ProductDetail/2145587 Service manuals aren't generally available, because the insides are so dangerous!

It's a guess, but something mis-connected on that new board. They usually have a number of edge connectors and you have two on the wrong pins. A guess never the less.
