Kenmore 80412 Microwave Oven - Answered Questions & Fixed issues

Well I'm reaching here---if the bulb did not fracture/break then it sounds like a capacitor popped--check your owners manual for reset button but I don't think there is one for the lighting---In addition if you can see the circuit board--look for burn spot or wet spot. GL

Have issue on my kenmore mic oven model 721.6365330 have no power although fuse is not burnout and poweroutlet has no either problem.

Have issue no power all the way fuse not burnout still got no power.

see the diagram attached: God bless you

SE stands for System Error, this means that the keypad has a short in the membrane and must be replaced to correct the problem.

The most likely cause is a bad magnetron, "heats food" the other two possibilities are the high voltage capacitor and diode. The cost to repair will a approach a new microwave oven.

i went to replace lite bulbs but didnt unplug it..removed cover and shorted out...now no lite and no turntable but does come on & heats food is it fixable.......ewave microwave kot-131uw....

The microwave oven has a main ceramic fuse located inside the unit under the keypad in towards the high voltage capacitor "silver and rectangular in shape" unplug microwave, remove top and allow 30 seconds for the capacitor to drain, use screwdriver and short across to make sure no charge is present, keep in mind the microwave carries dangerous high voltages.

THE BUTTONS ON MICOWAVE IS STICKING TRY PUTING A MILD SALUTION ON BUTTONS.

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week or so.

At our Web site, you can get details of our service, plus we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

The lights can can be inoperable or stuck on or stuck in "night light" mode. Sometimes this will similarly affect the fan operation or inside light, too.

Or you can order a new control circuit board from the Sears Parts Direct Web site.

Just enter your model number there.

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

What you are describing is a problem with the magnetron and it has become faulty, that is the main part that heats the food, the growling sound indicates it is loading down the power transformer that energizes the magnetron. The repair cost will not justify the expense "costly" replacement of the microwave oven "cheaper" in the long run.

It appears your magnetron or MCU has failed in this instance.

For replacement parts - head on over to PartSelect.com or RepairClinic.com and enter in your full model number for a full parts listing.
I recommend both sites because ...


FixYa has no affiliation with either site - I have been using and recommending them for years - trouble free.

PartSelect has a great schematic database for locating the part on your unit and great "testimonials" for each part that often times includes HOW-TO information.
RepairClinic has pictures of each part they sell and also a great how-to and troubleshooting for basic repairs.


If your unit has never been serviced - there should still be an original service manual enclosed in plastic taped to the inside of the shell.
In the service manual are Error codes, maintenance procedures, and troubleshooting steps you can follow.


Anything too complicated or beyond your scope should be handled by a professional.

If you think you want to tackle the repair - and have gotten stuck on a step - reply to your question and I will be glad to help you out.

It has a specified power rating of over 1000 watts.
There are 10 settings of power and is prrogramable.

get your manuals from the following link:

http://www.hammerwall.com/Download_Manual/59565/

That should be the default condition.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

Then I would refer you to the owner's manual.

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

Just enter your full model number there.

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 will ask you to register.

Many times, the owner's manual will also have the installation instructions inside.

If yours is not listed there for free, you would have to order it through the Sears parts site.

If some keys are still unresponsive, your membrane keypad has failed.

This can be due exposure to excessive heat, moisture or condensation, such as due to storage in an unheated building.

It's usually economical to order a whole new controller here.

Go to partselect.com and look for a ignitor.
When on this site... you will be asked to put in you model # which you will find in the drawer below oven.
This is a very simple project which should be about half hour to replace.
No electrical to turn off, no gas to turn off. Just a screwdriver, and the job is finished
