The problem lies with the mylar ribbon cable that connects the Keypad to the circuit board. The Mylar ribbon cable folds back onto itself and are touching. Over time the mylar 'breaks down' electrically and the wire traces in the mylar will 'arc' onto the other mylar ribbon cable. The solution is to separate the two mylar ribbon cables using paper and electrical tape. I've done this on several microwaves (not just Samsung) and it has worked every time. Patience and about 20 minutes is all it should take to fix it. I've described below how I did it for the SMH9187ST Microwave Good luck to all. 1.
UNPLUG
THE MICROWAVE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 2. 1. Remove the top front cover by removing the (2)
screws that are along the top edge (phillips). 3. 2. Slide the cover to the left about a half inch
(there are tabs holding the cover in place) and remove. 4. 3. Remove (1) screw from the top of the Keypad
Housing (phillips). Lift the Keypad Housing upwards about half an inch (there
are tabs holding the Keypad Housing in place) and remove. Be careful of the
metal grille that is just above the Keypad Housing as this may fall out since
it is being held in place by the Housing. 5. 4. Be careful not to pull on the wiring harnesses
that are attached to the Housing. Carefully unplug the wiring harness
that has the RED connector on it from the circuit board. Carefully unplug the
small white connector that has the mylar ribbon cable on it (this cable is
see-through and you can see thin, flat wires in it). 6. 5. Remove (4) screws that are holding the circuit
board onto the Housing. 7.
The Housing should now be free of the circuit board
and wiring harnesses. It's safe to let the wiring harness/circuit board hang
free, but caution should be used anyway. 8. 6. Remove the thin metal frame from the Housing.
There are (4) plastic tabs holding the frame in place. Using a small screw
driver pry one side of the frame away from the housing (try to do this to the
side that has smaller plastic tabs). When this side of the frame is free of the
Housing you have to lift the frame out at an angle to remove. It might put up a
fuss, but be patient and be gentle with it since the frame is thin and fragile. 9. 7. With the frame out of the way you will see the
mylar ribbon cable that is coming out from underneath the Keypad assembly. You
will notice that the mylar ribbon cable folds back onto itself as it re-enters
the Keypad assembly. This 'touching of the two ribbon cables' is where the
trouble lies. The ribbon cables may be stuck together. Carefully separate these
two and then insert a small piece of paper between them (paper can be 1/2 x 1/2
) and work the paper all the way down into the Keypad assembly as far as it
will go. 10. 8. Using electrical tape, apply a small piece
between the ribbon cables to hold the paper in place. Next, use more electrical
tape and put it between the mylar ribbon cables enough so as to keep the ribbon
cables separated. 11. 9. Re-attached the thin metal frame making sure to
press it into the Keypad assembly enough so that the (4) tabs click into place. 12. 10. Use electrical tape and apply it to the raw
metal edge of the thin metal frame to prevent the mylar ribbon cables from
rubbing on the metal edge. 13. 11. That's it. A final word of caution. Be careful
when inserting the ribbon cable connector back on to the circuit board. The
connector is loose and you need to gently place the ribbon cable into the
circuit board connector. 14. 12. Reverse the order of assembly from above. 15. 13. Plug in the microwave and then it should reset
and ask you to set the time. 16.
Hope this works for you !!
Thanks! this work for me....now my microwave working fine
Tim, Genius! Worked just like you said. Thanks so much for posting such detailed instructions.

Thank You Timm so much! I tried your advise and it worked like a charm. I was about to spend money on the repair when I found your instructions. Just goes to show that there is a design flaw in the control panel. The circuitry did not get fried by an elecrical outage as the Samsung CR tried to tell me. Thanks so much!
Thank you Timm your advice worked and my microwave is working perfectly. All of the "other" suggestions from techs on various sites were wrong. I really appreciate someone who knows what they are doing.

THANK YOU ! EASY TO DO THE REPAIR AND IT WORKED. THANKS AGAIN AND AGAIN.
did the job and saved me buying a new microwave! thankyou

It means system error, the cause is a short in the keypad memrane. The solution is replace the keypad.
See http://www.microwavecontrol.com/samsung_se_error.htm for details on the official fix.
SOURCE: Samsung Microwave Oven shows -SE- on the display. Why?
-SE- error means you
have a shorting membrane keypad.
Since
it's less than one year old, it would be fully covered under warranty.
I'd suggest contacting the manufacturer to get it fixed free.
You can find your
nearest Samsung-authorized service center here or call Samsung's Service Division at 800-932-3837.
We're
happy to help you with free advice and we'd appreciate your
thoughtful rating of our answer.
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.

We had the same problem and fixed it! Try hitting Pause/Cancel button until it shows zero on the display. Then press Kitchen Timer button and input 1:00. Then press start. Our microwave began working after trying that. Hope it works for you!
