Question about Kenmore 80412 Microwave Oven

Open Question

I have a Kenmore Microwave 721.80413. It justs beeps on its own and the number 7 appears across the time so 77:77 then it says start or power. Only a few of the numbers work and nothing else. I got it cleared and set the clock and its fine for a few minutes, then it starts beeping like someone is pushing the number 7 again. Do you think I should try to replace the Control panel?

It sounds like you press STOP two or three times to lock it. Maybe that (or another key) will unlock it.

The lock / unlock procedure will be covered in your owner's manual.

Or you can try a hard reset - unplug it from the wall for one minute, then plug it back in and try again.

If you don't have your manual, you can get one here. (Enter your model number without any spaces)

Try first unplugging power cable for ten minutes, and see if it clears the error.

Press and hold the "2" button for 5 seconds. It should beep twice when sounds are turned off or back on.

SOURCE: sylvania p70d20al-d5 microwave keeps beeping

I have the same problem with my microwave, the clock disappears and it says "enter" and "amt", I figured out it's the "beverage" button that is sticking. When I want to use it I just press "beverage" and then "reset" and just press them over and over until it stops. Usually it's on the first try, sometimes I have to press them a few times. Just don't do what I'm about to type though, I decided to get my razor knife and cut the button out carefully, I only cut the contacts on each side of the button, now no buttons work, I should have left it the way it was, at least I could use it that way.

SOURCE: Kenmore 721 microwave fan turns on by itself

I have the exact same problem with my Kenmore Microwave model 721 that we bought in October of 2005. The Fan will just randomly turn itself on even when we are not cooking. It has been doing this for the last few months and is starting to become more frequent. There is no way to turn it off except to unplug it for several hours.
Was there a recall for this defect ?

Twice my new kenmore microwave has just started beeping with the error code E11 appearing on the screen.Have to unplug it to stop it. WHat is going on?


I think this microwave oven uses an inverter to control the power output of the magnetron. Usually the microwave will advertise this feature with a trade name like "accu-wave" or "true-power" or some similar label on the front of the microwave. Assuming that is the case here, then the E11 error means a bad inverter

Kenmore pizza microwave beeps constanly


This is not a solution, it is a clarification request, but it looks like FixYa took away that helpful option, too.

I would suggest you post a whole new help request and be sure to tell us:

1. The FULL model number from the tag in or on the microwave. A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########

2. Let us know when it beeps. Is it only after cooking? While it's setting idle?

3. Next, let us know if the display has anything in it besides the normal clock time.

A good first step might be a hard reset, accomplished by unplugging the oven for a minute or two, plugging it back in, then resetting the clock.

The "7" pad on your membrane keypad is shorted.

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 of course one should never leave a microwave unattended while cooking.

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.

The keypad is part number DE34-00045H and you can order it here.

Otherwise, we do that for $39.95 plus parts. Feel free to contact us if you need more information or tips.

AMV420AA Microwave Oven will intermittently display 77:77


It sounds like the "7" pad on your keypad is shorting.

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.

There should 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 would like to have us do this for you, we do that for $39.95 plus part costs.

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

Disabling the beep on a Kenmore microwave


I have Kenmore microwave model 721.61820100.
It has an "Option" button. Press it. The display say "NUMBER"
Then press "1". The display should say "SOUND" and then "OFF".
Press "Start" and that beast turns silent, well not really, but the beeps are goooone.

If for some reason you don't like it this way repeat the sequence and the sound this time will turn "ON".

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.
