LG Dryer Error Code dE4 — Door Not Completely Closed
What this means
The dE4 error code indicates the dryer door is not completely closed or the door switch is not detecting a secure latch. This can happen if the lint filter is not pushed all the way in (blocking the door closure on some models), if the door strike is misaligned, or if the door switch has failed.
Alternate codes: DE4
Step-by-step fix
3 stepsCheck the lint filter
Make sure the lint filter is pushed all the way down into its slot. On some LG models, an improperly inserted lint filter prevents the door from closing fully.
Close the door firmly
Open and close the dryer door with a firm push until you hear the latch click.
Inspect the latch and strike
Check the door latch and strike for wear, damage, or lint buildup that prevents proper engagement.
When to call a professional
If the door switch has failed electronically, a technician can replace it.
