If this has a controller that runs a microwave and an oven, then the problem F2 means a temperature related fault such as a bad temp sensor / thermostat or a defect in the control board. If it's just a microwave, then the problem is likely a failing keypad. In many cases, those can be replaced economically. If you repost with your exact model number (62622 is not a complete model number) then we can advise you further and more specifically.

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.

SOURCE: 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.

SOURCE: Kenmore microwave loud popping noise when start

That sounds like maybe a high voltage wire or component is running too close to the chassis or one of the components connected to it.

Gruesome as it sounds, sometimes a pest can get inside the works and can move wires around or be killed, then its carcass can conduct electricity and cause arcing.

It may instead be a failing high voltage diode.

To find helpful exploded view diagrams and get part numbers, you can just enter your full model number (66562619200) at the Sears parts site.

Here are some links you or someone you know can use (in order given) for test help, but

(if it is NOT shorted or burned looking, it's probably fine)

SOURCE: 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.

How do I fix the key pad of a Kenmore microwave model 401.80084700?


I don't know of anyway to repair the keypad. Usually replacement (of the keypad/control console) is the only option. But you might want to remove the ribbon cable that connects the keypad to the control board behind it, clean it with a degreaser (like Fantastic or 409), dry it, and re-insert it, and then try again. (Remember to unplug the microwave oven first before you try that!)

The top quick access buttons stopped working 2 days ago. The bottom buttons still work but, we can't punch in a custom time. The only thing that will work is the 1 for 1 minute 2 for 2 minute...etc.


One of two things is happening, either you have broken connections in the membrane switches of the keypad and should replace the keypad(which is most likely) or your main control board has failed in a way that it can no longer read signals sent by the keypad.

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.

Microwave oven touch pad problem


The keypad very well could be worn from use and be working intermittently. Replacing the keypad (and the keypad face if it is a separate piece) is the most logical solution.

ASKING FOR TIME OF DAY BUT WHEN I PUT IT IN IT WILL NOT DO ANYTHING WHEN I HIT THE START BUTTON. THIS MODEL DOES NOT HAVE A RESET BUTTON.


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.

If it still fails, you likely have a bad keypad.

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.

Some buttons work, some don't.


The keypad may be bad. Most often they go bad due to moisture from cleaners being sprayed directly on them or steam from the cooktop when the vent fan is not used.

They can also go bad when the unit is stored in an unheated environment where there's a lot of air temperature change (hot during the day, cold at night, etc.)

It may also be some residue on the connections where the keypad plugs into the control board. Unplugging then replugging the keypad can sometimes clean them.

In other cases, a new keypad is needed.
