Samsung Microwave SE Error
What it means
On a Samsung microwave, SE means a Key Short Error. The control board detects that a touch-pad button is shorted or being held down (often for more than ~60 seconds), so it stops and shows the fault. SE and 5E are the same code - the 'S' is sometimes misread as a '5'.
Common causes of the SE error
- A stuck or shorted key on the touch pad
- Moisture, steam, or grease on or under the control panel
- A dirty or damaged ribbon cable between the control panel and the main board
- A failed touch pad/membrane that needs replacement
- A faulty main control board (less common)
How to fix the Samsung Microwave SE error
- 1Reset the microwaveSamsung recommends unplugging the microwave or switching off its circuit breaker for 60 seconds, then restoring power. This clears a transient short caused by moisture or a momentary glitch.
- 2Clean and dry the touch padWipe the keypad with a cloth dampened with a little dish soap or glass cleaner, then dry it fully. Let any trapped moisture evaporate before powering back on. Avoid soaking the panel.
- 3Free any stuck buttonsWith the unit unplugged, press each key once to release a mechanically stuck button, then restore power and test.
- 4Have the ribbon cable / touch pad servicedIf SE persists, the ribbon connector usually needs cleaning or reseating, or the touch pad needs replacement. This is internal work - see the safety note below.
🧰 When to call a professional
If a reset and cleaning do not clear SE, contact Samsung support or a qualified technician. Because a shorted key can in rare cases make a microwave start on its own, do not ignore the code. A microwave's high-voltage capacitor holds a potentially lethal charge even when unplugged - never open the cabinet or attempt internal repairs yourself.
Samsung SE error — FAQ
Is SE the same as the 5E error code?
Yes. SE (Key Short Error) and 5E are the identical fault - the stylized 'S' on the display is often mistaken for the number '5'. Both mean a shorted or stuck key.
Why does my microwave show SE even when I am not touching it?
The control board thinks a key is being pressed because it is electrically shorted - usually from moisture, grease, or a stuck button - not because someone is touching it. Cleaning and a reset often resolve it.
Can I repair the touch pad myself?
You can safely clean the external keypad with the unit unplugged, but replacing the touch pad means opening the cabinet, which exposes a high-voltage capacitor that can shock you even after unplugging. Leave that to a professional.
