Question about Samsung SMH7178STD Microwave Oven
My microwave has begun to beep each morning starting from 2:00am -2:30am . When I check the unit the display has this on it --SE-- , Most of the buttons on the keypad will not work, I have unpluged the unit . It comes back on I reset the clock & everthing is fine , but about 20 minutes later the process starts again. I have found if I unplug the unit & just leave it for the rest of the night the next morning when I replug the unit in & set the time everything. works fine the rest of the day , However the problem starts back that evening again around 2:00am . Is th --SE-- a error code , What is causing this problem? Could it have anything to do with the change from day light saving time , since it seems to start each evening around 2:00am
I have the same "SE" problem. After reading this thread here, I realise it's likely the keypad problem, which explains the microwave's behaviour (no key was working).
So there were two possibilities. (1)keypad failure and (2) bad connection.
Obviously the easiest thing I could start with is to clean the connection. So I first take the cover off. Behind the keypad is a circuit board. In addition to a few connections between the circuit board and other parts of the microwave, there is a ribbon connecting the keypad to the circuit board.
Loose the plastic on the connection, pull the ribbon out from the socket. I then used spirit to clean the exposed copper connections. Put every thing back to place.
Voila, it's working again and we have been living happily ever after.....

Best as I can tell the SE or 5E error on these Samsung Microwaves is a data entry pad error. I was able to fix mine by removing the pad, cleaning the connectors, and then plugging the pad back into place. I made a YouTube video that shows what I did to fix my microwave. Here is a link to that video: http://tinyurl.com/SamsungSE

Hold the start and cancel buttons down at the same time until you hear beeping. Release and it should be reset. I was about to either spend another 250 to repair it or purchase a new one until I tried this on my own. Soooooooo angry that it was not suggested by Samsung but sooooooo relieved. Hope this helps everyone.

There are two threads about this here. The other is at http://www.fixya.com/support/t132122-setup_not_working
I still believe the problem is related to daylight savings. Samsung has updated their FAQ to now include the SE code (wasn't there last month when we first had the error)
From Samsung FAQ:
"Some models are equipped with a sensor that can automatically adjust the oven's heating time based on the amount of steam in the oven. If your microwave is displaying E1, E4, or E5, there may be an issue with the gas sensor. For an E1 error, press the Cancel button and check on the food.
Other microwaves do not give specific error messages and just display "8888" on the LED. If you get this error message, your microwave needs service.
If the message is either ERROR or E-6, it indicates a mechanical fault.
For all error indications, including the SE or 5E error, try unplugging the microwave from the outlet for at least ten minutes and then plug it back in. If the error persists, the microwave may require service. Please use our ASC Locater to find your nearest Authorzied Service Center."

Hi, I had the same problem and in my case the fix was easy. First the root cause: there is a ribbon cable inside the microwave that connects the control panel to the keypad, which is kind of folded. Over time, condensation will make two pieces of the ribbon cable stuck together, causing short circuit. The solution is to separate the pieces and put a piece of paper in between. First you need to access the control panel by unscrewing the top grill of the microwave. After removing the top grill, you will see a screw holding the control panel to the oven. Just unscrew that one and remove the control panel. You will then see the ribbon cable. Inspect whether it is folded and the two sides are stuck. If yes, just separate them and put a piece of paper in-between.

I think I know what might be happening. If you hold the pause/cancel button for 8 seconds the "SE code" will appear. I noticed and so have others that it seems to usually happen at night when it's usually colder in the house. The keypad membrane might be contracting causing this problem. So as William E Miller said above the keypad membrane is probably the solution to the problem.

This is really odd. I would first suspect a setting under "My Choice" (press "My Choice" then 1, 2, 3, or 4 and check settings.
Or maybe a failing sensor.
But overriding all of this is the fact that it happens at roughly the same time each day, which is why I go back to suspecting an odd setting. Nothing in the owner's manual refers to this.
So I would recommend contacting Samsung for assistance. 1-800-SAMSUNG (1-800-726-7864), or see http:WWW.SAMSUNGSUPPORT.COM

I saw on another site that sometimes the ribbon cable will have one of the traces short to another. The fix was to separate the ribbon cables with a piece of paper as an insulator and tape in place. I tried it and have not had the error recur. It has been over a month since I tried the fix and the oven has been working fine. Prior to the fix, I was getting the S5 error within ten minutes of plugging my oven in. The fix only takes a few minutes to accomplish. Remove a couple of screws to remove the grill, remove a screw to remove the touch pad, unplug the cable, separate the ribbon cable, slide a piece of paper between the cables and reassemble. It's also possible that the cable had a bad connection and unplugging it was all that was needed.

I am done buying anything that has the word Samsung on it. We have had every Samsung appliance (front load washer/dryer, microwave and dishwasher) we have purchased repaired or replaced multiple times in less than 2 years.

The paper between the ribbon is the trick! So easy!

Wow! White eraser trick worked. Incredible. Used this link to get me to where I could actually figure out what was going on.

I tried everything suggested and it didn't work.However, i took a trip to my local appliance repair store thinking i could get them to replace the membrane......the tech suggested i go home and try a "white eraser" (has to be white) on the ribbon leads into the plastic clip. i did just that.......works perfectly.
i know it sounds crazy but it worked.....i was having sc code issues and the microwave wouldn't work. i cleaned those leads with a white eraser and it works perfectly.

Contacted Samsung as my microwave did the same thing after 1 year and a couple of month. Out of Warranty, of course!2 things here:1. Bought it with Amex so automatically doubled my warranty by another year.2. Contacted Samsung over the phone (not internet), and they said that there is a grace period of 6 months past the originally warranty. Phew! Their coming to fix the problem. Yee-ha!
