 :D Way to go Kean.  Not an obvious fix.  With your detailed instructions, I got my microwave up and running.  The ribbon cable was stuck together where it folded.  I used index card paper, cut it 3/4" x 1".  Did not go very far under the keypad but after taping it up, reassembled it and plugged it in viola, all worked.  Major kudos and many thanks.  I'm sure I avoided a $100 service call.   :thanks:

I registered at this site just to say thanks to Kean - article July 15 2014.  Maytag MMV4203 Made in 2010 code SE. I followed the directions from Kean and our microwave is back up and running with some paper and tape. Thank you Kean. It took me about an hour because it was new territory for me, but it was easy.

Just registered so I could extend a "thank you" to Kean for his detailed and effective instructions. After calling around local repair shops, nobody wanted to come out to make this fix, so I had to fix it myself. Saved my landlord time and hassle, anyway!

Thank you Kean for your instructions!  It worked perfectly!  This is the second time I have made a repair to this microwave, where last time it was the control board had burned out.  Ordered one via eBay and installed and worked.  Good to have a forum like this one!

Another new account to say, "Thanks!"

While it is possible that taking it apart and putting back together fixed it, I did the paper trick and my microwave no longer has ghosts hitting buttons and "-SE-" on the display, so I have every reason to believe that there was a short in that area.

The repair was amazingly easy (I'm good with electronics, but still) and saved me $100+ in parts.

I also registered to thank Kean.  Found this thread when searching for a5E error code.  Followed his directions on the mylar ribbon cable and Bingo!, were back in working order.  Probably saved me $150-$200 on a service call.  Thanks :cheers: :cheers:

This worked for me for a Maytag MMV4203 Made in 2010 code SE also. No electronics experience but I was able to pull off based on Kean's instructions. Thank you!

Kean, you're probably long gone, but you're the best. This took 20-30 minutes and some electrical tape, and that saved me from buying a new $300 microwave. Thank you so much!

This fixed mine.

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 !!

Kean, you have made another friend. Thank you so much. Your advise worked like a charm. The only thing different I did was  used a piece of electrical tape folded back on itself instead of paper. Thank a million Kean!!!

I too registered just to say thanks to Kean for the post above.  It took a little more than 30 mins. and now our microwave works again!  Thanks! I also read the post about covering the paper with electrical tape, but not until it was all back together. Might just take back apart to do that as well. BTW, I saw someone had used scotch tape. Don't recommend that at all.
