Kathy,
Unfortunately that probably means that your microwave is obsolete and you would be better off replacing it than trying to fix it. Sorry!

SOURCE: My Craftsman 53684 keyless won't work with my Craftsman 53930DM.

I've never seen the first set of steps you mention. You always need to press the "learn" button first so the opener will be in the mode to capture the new code. As far as I know it is not necessary to hold the Enter button on the keypad (at least I never have). While the "learn" LED is lit on the opener, just key in the new code and press Enter.

Maybe you should try clearing the receiver first by pressing the "learn" button and holding it until the LED either goes out or starts flashing (depends on model). Then try reprogramming. Maybe the little computer is confused.

Press and immediately release the SRT button and then walk over to your keypad and key in any 4 digit code you like and press enter.

To answer your question the opener is in vacation mode. Press and hold for 3 seconds the button on your wall control with the lock icon. The green light will stop flashing and you will be back in business.

SOURCE: Keypad won't work anymore

Lets make sure you are programming it correctly, make sure the battery is new. Press and release the learn button on the motor. Within 30 seconds enter in the 4 digit code followed by the up/down button. The light bulb should flash once. If you can't get it to code in this way you will need to replace the keypad. Thanks BB

Start button and quick minute and 0 not working


This is only a educated guess, some input is better than none:

If three specific buttons do not work the keypad either got something spilled on or in it or it is a bad.

Numbers 1,3, 4 and 6 no longer work


It's probably the keypad. The keypad is a thin plastic membrane type that is glued to the plastic control panel frame.

If none or only some of the pads are working, there may be some foreign substance on the circuit board, the keypad connection, or inside the layers of the keypad, the latter of which cannot be repaired.

Trouble is sometimes due to spray cleaner being sprayed directly onto the keypad. Cleaner should be sprayed on the cloth first, then use the cloth to wipe the keypad clean.

Never use an ammonia-based cleaner on plastic as the ammonia can attack and crack it.

A handy person can remove the control panel frame and see if there's any liquid inside on or behind the panel. If so, it is possible to dry it out, but often that does not work.

Another thing is to unlpug the power at the mains for several seconds. Plug it back in and see if it works. A reset may do it. At power-up, the display should flash or show a text
message. If not, a key may be stuck due to a foreign substance or a defective keypad.

We have critical safety, disassembly, and troubleshooting info at our site. You'll find a link to our site in our listing here on FixYa: http://tinyurl.com/yzjozk

If certain keys are not working, there may be some foreign substance at the point where the green or blue plastic strip from the keypad plugs into the circuit board. To check that:

1. Be sure the oven is disconnected from the power line while you are taking it apart.

2. The keypad connection is the green or blue translucent plastic strip that plugs into a connector near the edge of the board.

3. There are two tiny tabs (one on each side) of the connector that you can gently pull up on to unlock the connector.

4. Then the keypad strip will lift out. Clean both sides of the end of the strip with a pencil eraser or alcohol-based cleaner if you like, but do not use ammonia-based cleaner. Dry the end of the strip.

5. Put the keypad strip back in, making sure both sides are down fully.

6. While holding the strip down, push the connector back down to lock it.

7. Try the keys again with the door closed.

Also, you must have the door closed for the START button to work.

You can probably find an exploded view by entering your FULL model number here: http://www3.sears.com (the 3 is correct)

You can order Sharp parts from there or from Tritronics at http://www.wehaveparts.com

Flashing 88:88 display - no keypad response - no light


Hello,

I’ve read through your problem in an attempt to find a solution to my own similar issue with my microwave oven. Other solutions (like unplug appliance overnight and reconnect to power source the next morning) did not work for my appliance.

Just as I was about to call it quits and go out to purchase a new microwave; I gave it one last try. This time, instead of pressing any and every single button on the keypad, I decided to press BOTH the "Stop/Clear" AND "Start" buttons AT THE SAME TIME. . . . . Voilà! This worked for me, but sadly, it's now May-2008 and I'm pretty sure you're own microwave is long gone since your posting appears to have been quite some time ago. Well, hopefully others that stumble through these pages with similar issues may find some assistance with my approach. Oh, and btw. . .I got this idea (which worked) from remembering the instructions on how to reset my cellphone. Many thanks, ~paul

Microwave Keypad not working


This model does have a child lock. If it's on, the display will say "LOCKED". It is turned on and off by holding dfown the "0" key for 4-5 seconds. You may also have a bad keypad, which in many cases can be replaced. A bad keypad may be worn out due to age, damaged, or it may have gotten wet or otherwise contaminated. Moisture and contamination can be caused by spraying of cleaners, by storing the microwave in an unheated garage or shed, or infestation. I warn my customers to never spray cleaner directly onto the microwave keypad, since the liquid can get inside and "lock up" or even ruin the keypad or controller. Apply an alcohol-based cleaner (such as the purple kind) to a cloth (paper towels can scratch) and gently wipe it off. I suggest to my customers that they NEVER use any ammonia-based cleaner (like the blue stuff) on a microwave, since the ammonia will crack and distort polycarbonate plastics. Repost if you need more help.
