Question about Kenmore 62702 Microwave Oven

1 Answer

Some control panel buttons don't work

This Kenmore model # 721.80593400 has a few numbers on the keypad that are unresponsive. Otherwise, it runs great. I've got it taken apart thinking I can clean contacts or something but that doesn't look like an option. Where can I get a replacement, or am I barking up the wrong tree?

You need to replace the touch pad assy. Moisture gets up around the contacts and, it doesn't take much to short them out. Some will work, others will not. Eventually, others will fail, leaving it inoperable. Recommend fixing ASAP

My microwave keypad wont work the light is on and the reading says please touch clock and set time of dry


SEE THIS CAUSES AND FIX IT. God bless you
Touchpad and Control Panel If the microwave buttons don't work the touchpad and control panel assembly are probably defective.

Touchpad If the microwave buttons don't work the touchpad might be at fault. Generally speaking, if the display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.
ser Control and Display Board If the microwave buttons don't work the main control board is most likely defective and will need to be replaced.

Main Control Board If the microwave buttons don't work the main control board is most likely defective and will need to be replaced.

I have a Kenmor Elite microwave oven, model 721.66460400. The timer no longer work properly, i.e., I cannot set the cooking on button. Where would I find someone to provide parts and perfom work to get...


It sounds like a failed membrane keypad.

On some models, you have to buy a separate keypad.

I have uploaded a handy guide with pictures showing you what's typically involved. It's here.

In other cases, you can replace the whole control panel frame assembly, which comes with a ney keypad already on it. This runs more, but it's much simpler.

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.

Then you unplug the keypad (as per the photo below) and move the circuit board into your frame.

Some connectors on the relays have a lock:

You can find helpful exploded views and order parts from the Sears Parts Direct Web site.

That model number (721.66460400) is not showing up in my search. Please check it again.

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

The membrane keypad has failed.

On some models, you can replace the membrane keypad. I have uploaded a handy guide with pictures showing you what's typically involved.

On other models, the keypad is only available as part of the whole control panel frame. It's easier, but a little more expensive.

You may choose to do either yourself, or have it done for you.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

Kenmore microwave - unresponsive keypad


Repaired the unresponsive keypad on my older Kenmore (model 721.68100): Unplug. Remove integral cover for top and sides which is held in place by 5 metal screws. The cover then slides toward the rear. Unplug two connectors to back of keypad and clean them (I used contact spray cleaner). Some of the components retain a charge even when unplugged.

Keypad is inoperative


Is it possible that some spray cleaner got into the controls?

I always recommend that users instead spray cleaner on a soft cloth then wipe the control panel.

Also, I always recommend non-ammonia cleaners since ammonia can crack and damage plastic.

Otherwise, the spray can get into the controls and lock it up or make it act odd.

If it does not dry out over time, it may need to be manually dried or blown out.

The keypad may be damaged or worn out, or control unit may be damaged.

On 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.

Kenmore microwave model number 401.80084700 Displaying -SE-/-5E-


-SE- error means you have a shorted membrane keypad.

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.

There are three ways you can get it fixed:

DE34-00178X SWITCH MEMBRANE $20.30
ref#53 membrane keypad
take yours off as in the video at our site, peel the old keypad off as in this handy guide with pictures , clean the surface, stick on the new keypad
order by part number here
(We can do this job for you for a total of $70.25, but as you can see, the other two options are more practical and economical)

DE94-01647A ASY CONTROL PANEL $39.01
ref#66 control panel frame with keypad
take yours off as in the video at our site, disconnect the keypad strip as shown here, move your circuit board to the new frame, reinstall
order by part number here

DE94-01648A ASY CONTROL, BOX $58.12
ref#59 complete control panel assembly with frame, keypad and circuit board
take yours off as in the video at our site, then install the new one
order by part number here

If these parts are not in stock, they should be available in about a week or so.

Microwave keypad issue


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.

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.

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