I have a TE Error on my Kenmore Elite Microwave... what does it mean? It won't do anything... I've unplugged it to see if it will clear... nothing...


The cause of the TE error for us was grease/gunk on some exposed pins and flex connectors (communication bus between controller and keypad) that was interfering with communication with the keypad. Resolution to TE error: Remove the keypad / control board from the microwave. There are three screws on the bottom at the front to remove. Once those are removed, the keypad is held on by clips. Slide the entire keypad to the left and it will come loose. After it is loose, carefully remove all the wired connectors to the microwave. Lay the keypad face down on the counter and look at the control board. The control board is actually seperate from the keypad and connected via two thin flex strips with many small contacts (like a nintendo game connector) . Our flex strips were covered in grease from the hood fan operation. Carefully clean the strip and the connector (with a felt pen if you have one) and resassemble. This resolved the issue for us.

Slider part keypad not working properly, only number keypads are working


Possible that the flexible membrane strip of the connection to the slider keypad is broken off there by cutting off the connection.
These membrane strip wires must be procured to be installed back into the main board and connected to the slider pad.
Attempt only if you are experienced to do these delicate jobs.

Replace keyboard on Toshiba Satellite 1410-s173


First remove the AC adapter (Charger) if plugged in. Then remove the battery.

Next step is removing the Keypad Securing Strip. This is a plastic cover right Above the keypad, and below the LCD screen. Looking at it, you'll notice on the Left and Right sides of it, that it has a U-shape.
This U-shape covers the LCD screen hinges.

Take a small flat tip jewelers screwdriver, and come from the right side of this plastic strip. You will see a thin parting line, where this plastic strip meets the laptop body. Your flat tip goes in this parting line. You have to use finesse. It's doubtful you'll break the plastic strip, as it's REAL tough! But if you slip, you could scratch the plastic. (Actually, it's pretty hard to scratch that plastic! Just thought I would caution you. The plastic strip is made of a spaceage plastic. Pretty tough stuff!)

The plastic strip has tabs around the edges, every so often. These
plastic tabs snap into place, and hold the Keypad Securing Strip on. When you begin, it's a little tough to get that flat tip down in there. (Remember ->Jewelers screwdriver!)

Plus, you may be at one of the points that there is a tab. Usually there is a 'dimpled' flat place, that looks like a flat tip should go there.
With the flat tip jewelers screwdriver inserted a little, ease back on the screwdriver, and lift the plastic strip up.
It will look like it's bending. If you have another flat tip Jewelers screwdriver, or a small butterknife, you can insert it, and hold this part up. Then take the other flat tip, move over a little, and start lifting up.

Once this Keypad Securing Strip starts coming up, it will come to one of those tabs, and the tab will come up and out. You'll hear a POP, and think you broke it! You didn't.

Go along the edge, and keep popping this strip up. Use caution, as to how far you insert that flat tip screwdriver!
There are tiny little wires under there, and you don't want to pinch one, or tear it loose. Keep the flat tip, about a half a fingernail length in, and you won't.

Once you get towards the other side enough, the strip will let loose, and come up.
Without disconnecting the wires, see if you can lay the strip towards the back, and lay it out of the way. Towards the LCD screen. You are trying to get to the screws, that secure the keypad. They will be in a metal strip for the keypad, and towards the LCD screen.
I can't remember at this point if there are two, three, or four screws. You'll be able to see, and you'll know.

(Use Caution! You can easily drop these screws! They might go right into the body of the laptop. You MAY be lucky enough, to pick the laptop up, turn it over, and gently shake the laptop, to have them fall on the table. You MAY not be so lucky, and have to disassemble the entire laptop, to get to them!)

IF, the Keypad Securing Strip will not lay out of the way, so that you can get to the keypad screws, you'll have to remove it.
It isn't tough, but it looks daunting the first time.

You will see small White connectors in the middle of the cables.
Two wire cables, if memory serves. These connectors are small White rectangular blocks. There is a Female and a Male. You just take your fingernails, and ease the connectors apart.
Don't worry about how they go back together. They are different sizes. You just match up the size.

Now with the keypad securing screws removed, ease the keypad forward a little, and bring the front of it up to a tilted position. (Towards the LCD screen is the front of the keypad) You don't want to bring it straight up, as there is a flat ribbon cable you need to disconnect. The flat ribbon cable attaches at the back of the keypad. (Towards you) It has a White connector.

This connector is different, from the ones you have disconnected already. The connector itself has a locking 'bar'.
This thin rectangular piece of plastic, goes across the length of the connector.
It is positioned at the front of the connector. It comes forward, towards the flat ribbon cable end, that is connected to the keypad.

It slides. It only slides so far, then stops. It is at this point, that you remove the flat ribbon cable itself. The one towards the keypad. There will be No connector on that flat ribbon cable. It will be just the ribbon cable itself.

When you reattach it, you just slide the flat ribbon cable back into the White connector. Then you ease that locking bar back into position. The position that it started from.

Now reverse your steps.

How do i replace the keypad of GE Profile over the range microwave


We have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting. It will help you test the keypad with your meter.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

If you'd rather have us fix it for you, we do that for $39.95 plus parts.

DISCONNECTING THE KEYPAD

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 alcohol-based cleaner if you like, but do not use ammonia-based cleaner. Dry the end of the strip. (A pencil eraser is better and safer).

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.

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.

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.

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.

Microwave not working


For that model, the child lock is activated and deactivated by holding 0 then pressing 2. But that doesn't sound like your trouble. You may have a keypad which is defective, damaged or may have gotten wet or otherwise contaminated. Moisture and contamination can be caused by not using the fan when boiling on the stove top, direct 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. If this happens it must dry out or be dried out, unless the moisture has gotten too deep. Apply an alcohol-based cleaner (such as the purple kind) to a cloth (since 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. If the keypad or controller has gotten wet, it can sometimes be carefully blown out with compressed air or heat. Another thing is to unplug the power at the mains for several seconds por minutes. 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.

Control Panel not working


If it has a CUSTOM HELP pad (and that pad is working!) you should be able to press that to access the help menu. Child Lock may be the first item. If so, you're all set. If NO keys work, and the light comes on when you open the door, you probably have a problem with the keypad. Those can be replaced. An unresponsive keypad may be worn out due to age, may be damaged, or it may have gotten wet or otherwise contaminated.
