Title: Maytag Microwave Oven Locks up with 5E or SE fault code
Post by: tagarman on May 21, 2013, 07:46:16 PM
Hey everyone,  I am working on a Maytag above the range microwave oven, Model No: MMV1153BAS and Serial No: 13274069LE, Manufactured: 03/2007.  Once a while the microwave will shut down and lock up where nothing will work and the control panel will display a 5E or SE fault code.  I took the front and top grill off but can not find any information about the code and what it means.  My customer will unplug it for a while and then it will work again (for a while).  Does anyone know what this fault code means and how do I fix it.  A service manual what be helpful if anyone has one on this model.  Thanks for all your help! Tom

I'm pretty sure that's a code for a shorted keypad. I ran into that code about 6 months back. Same scenario, intermittent and unplugging would clear the code for a while. The tech sheet (should be behind the console) didn't list that error. Whirlpool tech support advised it was a bad keypad. I replaced it & it solved the problem.

I ran into that code today. Kind of weird that it uses the same exact code that Samsung uses for their touchpad. Makes me wonder if this certain model is made by Samsung.

I guess not weird. Just confusing when going to work on it. I worked on a GE laundry center about a month ago and took the front panel off and it was a dead giveaway that it was made by Whirlpool. I ended up using Whirlpool parts to fix it rather then order all the GE parts that I didn't have.

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 !!

Wow!  We followed the steps Kean posted and were also able to fix our microwave -- took us more like a half hour, but we have zero experience doing this type of thing and were able to pull it off.  Thank you!   :thanks:

I also used Kean's procedure and it seems to have worked great. I have a 2011 MMV 4203 Maytag microwave.  The instructions were spot-on -- especially the part about using patience to remove the metal frame and the part about the ribbon being stuck together- it was.  One thing I will add is to be careful with the white plastic locking device on the end of the ribbon that connects it to the circuit board. I had broken one of the locking tabs before when I had taken it apart and broke the other one this time while making the Kean repair. It was just stuck and you may need to use a pointed device to coerce the lock hook out of it's catch. To repair, I folded up some paper behind the ribbon to make the fit tight and secured it with some tape.

Kean's procedure worked great for me.  There was some soft adhesive inside the 90 degree fold of the ribbon cable that may be the culprit causing the breakdown of the ribbon cable insulation.  We used a thin piece of plastic that we cut to size and secured it in place with some Mylar packing tape.  The ribbon cable in our five year old Maytag microwave has probably been breaking down slowly for several months lowering the power level.  After the repair the water we heat for morning coffee and tea gets about twice as hot with the same time and power(full) setting.

@Kean-  :thanks: Your post had me fix my microwave for the cost of 35 minutes and 4 inches of electrical tape. I honestly thought I would have to replace the whole touchpad after taking the whole cabinet apart, and doing so would still have not fixed it as the ribbon cable was at fault. I would have been nuttier then squirrel droppings if I had gone through all of that for nothing. 7 screws, 4 clips, and electrical tape- I would have never imagined.

Created an account just to leave feedback! @Kean, thank you SO MUCH!  We moved into this house about a month ago and the microwave never worked, just an SE message.  I decided to do an online search to find some information and, after reading Keans instructions, 30 minutes later IT WORKS!!!! Awesome!  So thankful!  :thanks:  :thanks:

I thought my two year old Maytag microwave was kaput. It was as if the 8 key was stuck and then would beep and display SE. As soon as I'd plug in it would say to set the clock and then 8s would appear on the display. Found this thread and ten minutes later I've got a working microwave again!! Thanks so much Kean!

Kean, you're my microwave hero.  My may tag shutoff last night with this error code and with your outstanding instructions, and 30 minutos of time i was able to get the microwave up and running again. 

Thanks.

Killer Kean is spot on!! Thank you so much for the post. Following Kean's instructions step-by-step instructions worked great. After 30mins and 57cents for electrical tape, microwave oven is up and running.

I have one suggestion to add, instead of paper I used a chart paper and wrapped that with electrical tape which makes it an insulation and will prevent any fire hazards. I was not sure whether leaving paper between the flexible circuit may cause a potential hazard and therefore decided to add the electrical tape. Hope that helps.

I did exactly what Kean stated to do and it worked like a charm. I was home brewing beer and because the amount of time needed for a boil it shorted out the keypad. The fix was genius. There was some adhesive type material, or at least it felt like it, in the 90 degree fold of the ribbon. THANKS SO MUCH!

 :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 (http://appliancejunk.com/forums/index.php?topic=12215.msg78230#msg78230).  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:

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!
