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!)

That error indicates a bad keypad. You will have to replace the keypad/control console assembly.

The keypad control board is defective and must be replaced.

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:

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.

-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:

Just enter your full model number at the Sears parts site.

On the resulting page, look to the right for the blue "View Manuals" button.

That Sears-related site has many free manuals. While the manuals they list there are all free, they will ask you to register.

Many times, the owner's manual will have the installation instructions inside.

If yours is not listed there for free, you would have to order it through the Sears parts site.

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

This can be caused by slamming the door or by habitually opening the door while it's cooking without hitting the Stop pad first.

If you or a friend decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

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.
