Samsung Microwave DE error code

The microwave thinks its door is not securely closed - a door error. It will not start cooking until the door registers as shut, as a safety measure.

Also shown as: DE, dE

Last updated: October 6, 2026

Quick answer: Samsung microwave error code DE: door not securely closed. The most common cause is door not pushed fully shut. Try this first — open the door and close it firmly. If that does not clear it, inspect the latch for damage or debris.

What causes the DE error?

  • Door not pushed fully shut
  • Damaged or misaligned door latch
  • Worn door switches not registering closure
  • Food debris in the latch area
  • Door seal or hinges misaligned after impact

How to fix Samsung DE — step by step

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

  1. Open the door and close it firmly
    Open the door fully, then push it shut until you hear and feel the latch engage. A door that looks closed but is not latched is the most common cause of DE.
  2. Inspect the latch for damage or debris
    Look at the door latch hooks and the slots they enter. Clear out any food debris and check for cracked or bent latch parts.
  3. Check the door alignment
    Look at the door from the side - it should sit flat against the frame with no visible gap. If it was slammed or hit, the hinges may be bent.
  4. Unplug for 2 minutes and retry
    Unplug the microwave for 2 minutes, plug it back in, close the door firmly, and try a short cook time. If DE persists with a good latch, the door switches need service.
    Safety warning: Never tamper with or bypass door switches - they are critical microwave safety devices.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • DE persists with a firmly closed, undamaged door
  • The latch hooks are cracked or bent
  • The door switches need testing or replacement
  • The door or hinges are misaligned

Frequently asked questions

Is it safe to use the microwave with DE showing?

The microwave will not run with DE, which is the safety system working. Never try to defeat the door interlock - it prevents microwave energy from escaping.

The door looks fine but DE keeps appearing. Why?

The internal door switches wear out and stop registering even when the door closes properly. Switch replacement is a technician job.

Can slamming the door cause DE?

Yes. Repeated slamming bends the latch and hinges over time, eventually misaligning the door enough to trip DE.
