Quick answer: Frigidaire microwave error code SE: shorted keypad. The most common cause is shorted key on the membrane keypad. Try this first — unplug for 5 minutes. If that does not clear it, press keys and dry the panel. If the code persists, call a qualified technician.

What causes the SE error?

  • Shorted key on the membrane keypad
  • Moisture trapped behind the control panel
  • Worn keypad with an electrically shorted key
  • Failing electronic control board

How to fix Frigidaire SE — step by step

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

  1. Unplug for 5 minutes
    Unplug the microwave for 5 minutes, then plug it back in and test the keypad. This clears a false shorted-key reading from a glitch or brief moisture.
  2. Press keys and dry the panel
    With the microwave unplugged, press each keypad button firmly and wipe the panel with a dry cloth. If SE appeared after steam or splashing, let the panel dry for several hours before powering up.
  3. Check warranty status
    If the microwave is under warranty, contact Frigidaire service rather than attempting anything further. Keypad and board faults are typically covered.
  4. Call a technician for keypad or board replacement
    A persistent SE means the keypad assembly or control board needs professional replacement. Microwave keypads sit in front of high-voltage parts, so this is not DIY.
    Safety warning: Never remove the microwave cover. The capacitor can hold a lethal charge even when unplugged.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • SE returns after unplugging for 5 minutes
  • Keys are unresponsive or trigger on their own
  • The keypad assembly needs replacement
  • The control board is at fault

Frequently asked questions

SE vs F3: what is the difference?

They are closely related. SE usually means a shorted keypad key; F3 means a key has been shorted for over 60 seconds. Both point at the keypad.

Will unplugging fix SE?

It clears glitch readings, but a genuinely shorted key returns SE as soon as power is back.

Can pressing the keys fix SE?

Sometimes pressing a mechanically stuck key frees it. An electrically shorted key needs the panel serviced.
