Quick answer: Samsung microwave error code SE: keypad or control board fault. The most common cause is a touch key stuck or shorted. Try this first — press every button firmly. If that does not clear it, clean the keypad with a soft, dry cloth.

What causes the SE error?

  • A touch key stuck or shorted
  • Moisture or steam under the keypad membrane
  • Grease or residue on the touch panel
  • Ribbon cable fault between keypad and board
  • Failed electronic control board

How to fix Samsung SE — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Press every button firmly
    With the microwave idle, press each key on the panel one by one. This frees a mechanically stuck key, which is the most common SE trigger.
  2. Clean the keypad with a soft, dry cloth
    Wipe the panel dry to remove moisture, steam residue, and grease around the keys. Do not spray cleaner directly onto the keypad.
    Safety warning: Keep liquids out of the panel edges - moisture under the membrane causes SE.
  3. Unplug for 2 to 3 minutes
    Unplug the microwave for a few minutes, then plug it back in. This resets the control board after a transient keypad glitch.
  4. Avoid pressing keys with sharp objects
    Using pens, knives, or long nails on the touchpad damages the membrane and causes repeat SE faults. Always use a fingertip.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • SE returns with a clean, dry panel
  • Keys are unresponsive or visibly damaged
  • The keypad membrane needs replacement
  • The electronic control board is faulty

Frequently asked questions

The microwave beeps nonstop with SE. How do I stop it?

Unplug it to silence the beeping. If SE returns when you plug it back in with a clean, dry panel, the keypad or board needs service.

Can steam from cooking cause SE?

Yes - it is one of the top causes. Steam condensing under the keypad membrane registers as stuck keys. Ventilate and wipe the panel dry.

Is SE the same as the washer 5E drain code?

No - same letters, different appliance. On Samsung microwaves and ovens, SE is a keypad fault, not a drain issue.
