Question about Kenmore 80809 Microwave Oven

Kenmore Microwave Model 721.80593402

I recently had just finished using my microwave when I shut the door a little harder than usual. When I returned to use the unit a few minutes later, I noticed the inside light was on, and the although the control panel registers input, the "Start" button will not work. Thus the unit is inoperative.

The unit is fairly new, only a year old and the light inside the unit has remained on.

Any suggestions would be sincerely appreciated.

This is usually a broken or misaligned door switch mount or possibly a bad door switch.

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and
disassembly information at our site, linked here on Fixya:

Kenmore microwave model 721 loose door

Loose bottom hinge - slide the microwave to the edge of the counter, and look at the bottom hinge - you may have to remove something to see clearly. Its likely you are missing a screw or the screws have worked themselves loose.

My microwave is cooking without me wanting it to

The fact that pressing CANCEL did nothing leads me to believe the controller may have failed but a failed door interlock could be a contributing factor.

The microwave model is Kenmore 721.62464201. It's arcing.

This is usually caused by grease or food debris.

First these areas
should be cleaned with a mild, non-ammonia cleaner on a soft cloth. You can use a grille brush if it's stubborn.

Any metal chipped or charred metal will have to be sanded smooth and clean.

Then you should apply some high-temperature appliance paint, available from places like Wal-Mart or Lowe's.

You can find handy exploded views and order any needed parts at the Sears Parts Site.

Kenmore microwave model 665.61629100

Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it.

Door switch If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work.

Kenmore elite microwave oven displays "Locked" and will not respond

My Kenmore Elite microwave (don't have the model number in front of me) also mysteriously locked its own keypad (we were sitting in an adjacent room, heard a strange beep, and got up to find the LED reading "Locked."). I pressed and held down the Stop/Clear button for ~10 seconds and it returned to normal.
