Samsung microwave auto starting

"SE" error means you have a shorted membrane keypad.

On some models, you can peel off and replace the old keypad.

On others, it's best to replace the control panel frame, which contains a new keypad already.

You didn't mention your full model, but if it;s the same as the category in which you posted (SMH9187ST) here is a specific solution:

The simplest way to fix this is a simple DIY solution, to replace the control panel frame assembly, which comes with a new keypad already attached.

It is part number DE94-02001C "assy control panel" and you can order it from the Pros here for about $30 plus shipping.

They may not have it in stock, but if you order it, they can have it in a few days.

You can download the service manual from our site here.

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.


Some connectors have a lock:




Then move your board to the new panel assembly, but be careful since the display is made of glass.

Hello

GE microwaves with a digital display will show an error code when there is a problem or malfunction with the unit. One type of error code that will be displayed on a GE oven and require troubleshooting is a code F3. An F3 error code indicates that the keypad for the control panel is bad or has a short. This will cause the microwave to beep continuously after the set clock message appears.

Unplug the power cord for the microwave from the electrical outlet. Pull the microwave out from the wall and set it on a table or the counter.


Find and remove the two screws from the top of the grille, on the font of the unit, with the Phillips-head screwdriver. Pull the grille off of the microwave.


Find and remove the screws that are used to secure the control panel to the microwave frame. Lift the control panel unit up and away from the microwave.


Find and remove the screw that is used to secure the green ground wire. Pull out all of the connectors and ribbon cables from the control board.


Apply heat from a hair dryer to the front of the control board for at least 30 seconds. Make sure the hair dryer is at the low setting. Pull up on one corner of the top membrane, then peel it off of the control board.


Repeat Step 5 for the other membrane that is on the control board.


Insert the pliable circuit of the new membrane through the opening in the control board. Remove the wax backing to expose the adhesive for the membrane. Place the membrane onto the control board.


Peel the wax backing off of the top membrane, then place it on the control board.


Place the control board back on the microwave and secure it with the screwdriver. Reattach the grille, and set the microwave back in place.


Plug the microwave back into the power outlet and reset the clock.

Yes, it's probably a failing membrane keypad.

Since you didn't mention the model number, I have to be kind of general.

On some models, the membrane keypad has to be peeled off and a new one stuck on.

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.

On some models, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.

In that case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.

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.

Next, disconnect the strip as shown in the photo below, then remove the screws that hold your circuit board in the old frame.

Hope this helps.

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

It's most likely that the keypad is worn out or possibly you have a flaky door switch.

We have full details, critical safety, disassembly, and troubleshooting info (as well as door switch testing info) at our site. You'll find a link to our site in our listing here on FixYa: http://tinyurl.com/yzjozk

You can usually order Samsung parts (either the keypad / membrane switch or control panel with keypad) from http://www.samsungparts.com but that model number is not showing up, so you may have to call or e-mail them through their site.
