There’s no doubt that microwaves one of the greatest conveniences to own in your kitchen. Yet still, they’re not perfect and can malfunction from time to time.

The good thing is that modern microwaves are created to display error codes in case if something will go wrong. This makes it much easier to troubleshoot when you come across operation errors.

When the SE error code appears on a Samsung Microwave it indicates that your unit has a key that’s stuck on the control pad or ribbon cable connection is dirty or the electronic control board has failed.

Today we will discuss the SE error code that can appear on Samsung microwaves. We’ll talk about what the code means and ways you can fix it.

What is the Samsung Microwave SE Error Code?

As we mentioned above, SE code show up on the display when touchpad or one of the buttons is stuck in the ON position.

The SE code is generally associated with the microwave beeping several times, displaying the code, and not working until the door has been opened and closed again.

The SE code issue can lead to the microwave operating on it’s own, which can allegedly result in a house fire. So, if you have this problem, leave the machine unplugged or the door open until the repair is completed.

Always keep in mind that microwaves can be inherently dangerous to repair. They contain internal high voltage components that can hold a lethal electrical charge even after it’s unplugged.

For this reason, if you are inexperienced it’s best to hire a professional to diagnose and complete any repair on this type of appliance.

However, if you are knowledgeable and would like to give it a try yourself, we’ll discuss how to make these repairs below.

Ways To Clear the SE Error Code

Before jumping to the conclusion that you need to either call a repair service or purchase a new microwave, try resetting the unit.

This is done by unplugging the microwave from the wall or turning the breaker off to it for at least 60 seconds.

If the error code was simply a fluke, the device will start back up and operate perfectly. However, if you keep getting this code, check the two parts below:

Key(s) Stuck on the Control Pad

Any time buttons begin to malfunction on a Samsung microwave the SE code will be displayed.

If you find that the microwave control pad, or touchpad, doesn’t respond, but the display still lights up, then the problem is probably with the control pad.

This component consists of a series of soft touch electrical switches. They are usually made from two layers of thin Mylar plastic with material on the inner surfaces that is conductive.

A gap is formed between the two surfaces that separates the conductive coating until the user applies pressure, thus helping the two surfaces contact each other.

When this contact occurs, it completes an electrical circuit that provides input signals to the touchpad.

After regular, prolonged use the conductive coatings eventually disintegrate and are unable to make a good contact. This prevents the proper signals from reaching the control board.

To access the control pad, you will need to first unplug your Samsung microwave, and remove the cabinet.

The control pad is often attached to the actual control panel, and is generally connected to the electronic control board with flat ribbon style connectors.

Before going any further, you will want to check the connection to see if it looks okay. This part can be tested with a multimeter to determine if there is continuity.

The multimeter should read a few ohms of resistance for each control pad when it’s engaged. If you find no continuity, you’ll need to replace this part.

Another thing to check is, to remove the ribbon cable from the control board and clean copper connections with an eraser and alcohol propylene.

But, If everything above will not fix the problem, then you need to replace the whole touchpad.

Here’s how to replace the control pad:

  1. Unplug the unit to prevent electrical shock
  2. Remove the exhaust hood, also known as the vent at the top – there should be two screws
  3.  Slide the grill up and to the left to completely remove
  4. If you have a freestanding unit, you may have to remove the metal from around the top and sides before moving on to the next step.
  5. Remove the screw that holds the display panel in place
  6. Pull up and pivot the panel out
  7. Remove all wires attached to the control panel. Remember where each connector goes to ensure proper reinstallation
  8. Begin reassembling the wire harnesses to the new control pad and work backward to put your microwave back together.

Failed Control Board

The same issues may occur if the control board has failed.

The control board generates low voltages that are subsequently supplied to the touchpad. Basically, when a button is depressed, a voltage signal is sent back to the control board.

When the input signals are received by the control board from the touchpad or membrane switch, it uses the commands to turn on output relays that control specific microwave components.

Such components include the magnetron and motor for the turntable.

So, if the control board is not generating enough low voltage signals, or if it doesn’t sense the input signals from the touchpad, then output functions will not be able to occur.

Your best option is to verify that the touchpad and connections are in good working condition, before moving onto the control board.

If you find that the control board is defective, you will need to disconnect the power to the microwave, remove the cabinet and control assembly, and install a new part.

In the end, the SE error code can cause you a great deal of headaches. Be sure to check both the touchpad and the control board, as one of these components are probably defective.

  1. I’ve been fighting this for years. The fix would work ( sometimes) sometimes it would last a year. Other times minutes – days before the dreaded -SE- code came back. Sometimes it would come on on its own. Scary right. Well I pulled off the control panel and flipped it over, it was covered in gunk from cooking. Sprayed it down with a mild detergent and water spray scrubbed it with a paint brush. I then spray it with rubbing alcohol and scrubbed it with another paint brush. Did this several times, blowing out much of the alcohol and looking for any deposits left behind. Then one last alcohol spray down and dry it sing a dry paintbrush. Hopefully this is the fix.

  2. Thanks for the tip.
    I cleaned the cable as suggested by you and the SE error code was gone.
    I hope the problem is fixed and won’t come back.

  3. Thank you so much. Cleaning the end of the flex PCB seems to have fixed it. The contacts were brown with grease, an eraser and 96% isopropyl alcohol cleaned it up. It’s so nice not to trash it!

    It’s a clever and cheap design, but adding a little high temperature (removable) potting over the FPC connector would probably prevent a ton of needless failures.

  4. Cleaned the ribbon and worked great for 15 minutes then the microwave turned on fan was on hi, then off then on again. I unplugged it and was wondering do I replace key pad or control board?

  5. This worked great! We thought for sure it was the keypad but we followed the directions above and it fixed the issue. THANK YOU!

  6. Thank You very much,
    Was sitting on the couch and all starting hearing my microwave beeping in the kitchen. Searched the -SE- Code and found this thread. Im glad I didn’t have to take the whole microwave out just the control panel and top panel all you’ll need is Philips screw driver to do the job. Whole process took 15-20min. I had some grease build up on the inside of the panels that I had to clean. I assume that’s probably what was on the cable also.

  7. Thanks, cleaning the ribbon cable connection at the PC board worked for me as well (2012 Samsung). Pull the locking mechanism at the connector up before pulling the cable out. I used a pencil eraser and rubbing alcohol to clean the cable. Also note remove the outside case panel to get internal access, usually 5 or 6 Phillips screws.

  8. Thank you Eugene!!! I wonder how many microwaves might have gone to the landfill if it weren’t for your help. The eraser trick worked perfectly.
    One suggestion: please consider adding a quick description and/or additional picture for releasing the ribbon connector. Although, most who are brave enough to attempt this repair could probably figure it out anyway…

    Thanks again!

  9. • Sound On/Off Feature
    Hi, Just completed install on my model ME17R7021ES. The beep is a deal breaker, and the Sound On/Off is listed as a feature, details to activate are nowhere to be found.
    Most appreciated.

  10. I almost can’t believe the first part works! So far our unit has exactly the same symptoms as described. The ribbon wire is the culprit. The oil and vapor caused it to corrode and mess with the connectivity. The procedure is very simple yet very effective. It’s the cheapest “repair” so far!

    Thank you very much!

  11. Goodevening,
    A BIG THANK YOU !!!!
    We had a family get-together over the weekend,and only when had left I discovered my trusted Samsung Microwave , Model MG28F301TAK displaying
    SE error code.
    I removed and cleaned the flat ribbon style connector and went further to
    remove control panel,only to discover 2 square buttons (timer/clock) had been depressed and stuck on control pad.This was due to sheer negligence!!
    Re- assembled above and all is now working well.
    Thanks,once again.

  12. Hi Eugene,

    good tips on fault finding on the Samsung MC28H5013AW microwave oven.

    I had the SE error code, opened the case, cleaned the ribbon connector with a pencil eraser. The contacts went from dull brassy colour to bright silver. I replaced the case, plugged in and it all works.

    Thanks,

  13. Thank you!!! I was able to fix my 5E error by just cleaning the ribbon connector with a pencil eraser. I can’t believe that it was this easy to fix. Although I did watch a video that showed how to remove the panel and connectors. Otherwise I wouldn’t have known how to release the lock on the ribbon connector before pulling it out.

  14. Thank you for this advice. I managed to fix the SE error on my samsung microwave by removing and replacing everything as described above. Might just be temporary but it is working now.

  15. My 2-year old Microwave model: ME20H705MSS failed to operate after a 4-day power outage and shows error code SE. The controls are across the bottom of the door. I am disappointed that we will probably have to replace a unit of this age because repair cost will likely exceed current value of the unit.

  16. What is the cause of the microwave malfunctioning.
    Why will an error code SE appear.
    Is it cause we mishandled the microwave or negligence
