Microwave keypad issue

Dear Microwavesvc,
Having problem with "Start" button on keypad. It will not work. The auto cook functions seem to be working for my Kenmore Model #721.6262220 along with the Oven fan, etc although some of the other buttons are "touchy." I have to push them two or three times before they activate. I noticed you wrote a solution about fixing the electronic keypad. I am concerned that with this issue I would be better off buying a new microwave. Please advise.

You have a failed membrane keypad.

Most of the time, this is an economical fix. But shockingly, this keypad runs a whopping $110!

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 exploded views and order parts by entering your model number at the Sears parts site.

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

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 repair for you, we do that for $39.95 plus part costs.

Feel free to contact me directly (and please remind me of your model number) for more information & help.

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

We keep getting A MESSAGE "select action 1.0lb quick defrost" which displays every 15 minutes after any function on the Advantium 120 is used.


I surmise there's a short in the Quick Defrost button on the keypad. Either the keypad has collapsed there, or some contamination has gotten in. Another possibility is a failing program memory bit in the controller chip, but a contaminated keypad seems most likely. What happens if you press and hold that button while trying to key in another instruction? Is there any change in behavior?

Auto Cook not working


If autocook is not working and everything else it, there is an issue with the sensor in the oven that detects the steam, The emission of steam is what triggers that unit to shut off. If it wont cook on any settings then the issue is with the microwave generator not putting out enough power. This could be from a lot of things.

My oven is not heating anything although everything else seems to be working fine. Your site said i may need a multi tester, what is this and where might i find one cheap.


Push the microwave door tightly closed. The computer will not start cooking until the door is closed for safety reasons. Some models of microwave will give a warning on the screen if the door is open.


Ensure you have programmed a heat setting, entered a cooking time and pressed the "Start" button on the microwave's keypad. Check that the microwave is not set to "Defrost" mode.


Unplug the microwave and wait for one minute. This measure will reset the microwave's internal computer if it has frozen or scrambled. Plug the microwave back in and try again.


Ensure the keypad lock mode is inactive. Most microwave ovens have a lockout feature that prevents children from starting the microwave while unsupervised. Lockout mode is usually deactivated by holding down the button that bears a padlock symbol

Start button on microwave does not work


Some numbers are missing off that model number. Would that be model 721.62622200?

(If not, please reply back with the correct model number off the tag)

If it's cooking with the programmed buttons, but Start is not working, it sounds like the keypad has failed.

The keypad for model number 721.62622200 is no longer available as a separate part.

So you'd have to buy the entire controller assembly, which includes the plastic frame, keypad, and circuit board, etc.

It is part # 4781W1M307A and it runs $110.10 at the Sears parts Web site.

It sounds like the keypad is worn out. The fact that you can get them to work sometimes by what direction you push on them, tells me that the contacts are not working correctly.

Did you have this problem prior to the fuse blowing or did it start after you replaced the fuse?

I don't believe the fuse blowing is related to the keypad problem. I also don't believe that you have a microprocessor problem because you say that the function buttons work but the number keys don't work right. If the microprocessor was faulty, it would not be able to read any of the keys.

The fact that the number keys are not working doesn't surprise me. When you go to cook something, you will press the number keys several times, while only pressing start or stop once. This is why your number keys have worn out first. These keys have a limited number of cycles (presses) and it sounds like its time for a new keypad.

Please let me know if I can be of further assistance to you.

Good Luck!

Powers up but does not START cooking = Displays colon after you press START


I would check your onwer's manual for any other specific reset instructions. Generally it reset by unplugging it from the wall for a few minutes. Does the microwave require you to set the time and date before it will work? Are all the keys on the keypad working or do they seem to? If not, you may have a bad, damp, or corroded keypad or control circuit board. I can follow up more on these if it seems like your problem. Please met me know what you find.
