dE
Door Error
The error code dE on your LG Dryer indicates a specific system failure categorized as "Door Error". This guide walks you through the most likely causes and the correct repair sequence.
Owner's Summary
Your LG dryer's door sensor isn't confirming a closed door. Lint buildup around the latch mechanism is the most frequent cause and is free to clean. Give the door area a wipe and close it firmly again.
Symptoms
LG dryer will not start, dE displayed, door appears closed
Common Causes
- Door not fully latched
- Lint accumulation around door switch
- Worn or misaligned door latch
- Faulty door switch
How to Fix
- 1 Close door firmly until you hear a click
- 2 Clean lint from around the door switch area
- 3 Inspect door latch alignment and adjust if needed
- 4 Test door switch continuity and replace if faulty
Tools You'll Need
These are simple, low-risk fixes most homeowners can do with tools already in a basic toolbox.
Technical Explanation
The LG control board monitors the door switch state continuously. dE is generated when the switch does not transition to closed within the expected window after the door is shut, or opens unexpectedly during a running cycle.
Is It Safe to Keep Using?
Safe. This is a safety interlock — the dryer simply won't run with the door open.
Technician's Pro Tip
Lint dust accumulates in the door switch slot over months of use, eventually preventing the latch pin from fully engaging the switch. A cotton swab or compressed air clears this in under a minute.
