LG dE: Door not fully closed or latched

The dryer detected that its door is not completely shut, so it will not run. It is usually a simple latch or lint-filter issue, though a failed door switch can also cause it.

Most likely causes

  1. Door not pushed shut firmly enough to engage the latch
  2. Lint filter not seated all the way down, blocking the door
  3. Clothing or an object caught in the door opening
  4. Debris or lint buildup around the latch or strike
  5. Faulty door switch or door lock assembly
Before you start — unplug the dryer, and on a gas model shut off the gas supply. Let it cool first — the drum, heater and exhaust can be hot. If a step involves the heating element, wiring, or opening the cabinet and you're unsure, stop and call a qualified technician.

Step-by-step fix

1Reseat the lint filterSlide the lint filter fully into its housing so nothing keeps the door from closing completely.
2Close the door firmlyPush the door shut until you feel the latch click, making sure no laundry is trapped in the opening.
3Clear the latch areaWipe away any lint or debris around the door latch and strike so they can engage cleanly.
4Power resetUnplug the dryer or switch off its breaker for about 10 seconds, restore power, select a cycle, and press start.
5Call for service if it persistsIf dE returns with the door properly closed, the door switch or lock assembly likely needs replacement.

Still showing dE?

If you’ve worked through every step and dE keeps returning, an internal part likely needs testing and replacement. That’s a job for a qualified appliance technician, who can measure the suspect part against the service-manual spec before replacing it.
