When we plug it in, it will display #5 and beep and put another 5 and then another 5-but it does not work. can you please help us to fix this problem. It is stainless steel and we had paid a lot of money for it and would like to fix it if possible. Thanks, Shainaz

SOURCE: 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. 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, it will need disassembly, and we have *critical* safety & disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk 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, then with 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.

SOURCE: our Samsung MW1030WA Serial #

The "7" pad on your membrane keypad is shorted.

If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.

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.

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.

The keypad is part number DE34-00045H and you can order it here.

Otherwise, we do that for $39.95 plus parts. Feel free to contact us if you need more information or tips.

SOURCE: my samsung SMH7187STG microwave handle broke off.

This handle breaks because the screw holes attaching the top and bottom brackets where machined slightly off. If you lay the handle on a flat surface the handle will rock back and forth. In order to flush the handle securely to the door the handle must be overtightened which eventually causes the plastic to crack and fail. Will be replacing my third handle in two years.

SOURCE: The microwave display shows "--SE--" I have not

SE error indicates a short in the keypad assembly. This will mean the the control panel or smart board will need to be replace.

Microwaves are not good do-it-yourself projects. Microwaves are extremely dangerous to work on even while unplugged. Even unplugged some components retain a lethal amount of voltage.

Here is a link for the website and contact technician: Sears Home Services .

Hope helps.

The display panel readout has a 5E or possibly a SE on the dislplay constantly


SE error means you have a shorted membrane keypad.

You have a shorting membrane keypad. If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.

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.

We would need the model number in order to provide you with free assistance.

It will be one of these:

SMH9151STE
SMH9151STE/XAA

It is usually found on a tag located inside the cooking cavity or around the door frame or controller frame.

Since FixYa is still not notifying us when you respond to clarification requests, you will have to post a new help request with your model number and symptoms / questions, or you may contact us here for this free assistance.

In some cases, it is a simple do it yourself repair.

Sounds like it over heated and you have some wires that might have melted and are causing this issue. In either case I would not recommend using it any more for fire hazards and would recommend you replace it. repairing these is not economical. You can unplug it and let it set over night then remove the case and see if you can find what has gone bad and decide if you need further info on a repair if you chose that route but i can't tell you what the problem is without seeing it or a better description of what is burnt.

As long as the air flow is good, gravity shouldn't make any real difference.

Microwave comes on by itself in middle of night


This absolutely is a fire hazard.

Until it is fixed, you are right to either unplug it or simply leave the door open when you;re not using it.

You have a failed membrane keypad.

I also have the same microwave model and with the same problem. It is not quite 2 years old. I have a service call scheduled but did e-mail customer service at Whirlpool to inform them of this. Sounds like it could be defective model and a fire hazard. You should also inform them of yours.
