Direct answer: An LG dryer dE code usually means the control is not seeing a fully closed dryer door. Most of the time the problem is a door that is not latching cleanly, a bent or loose strike area, lint packed into the latch opening, or a failed dryer door switch.
Most likely: Start with the simple stuff: open the door, clear lint from the latch pocket, press the door closed firmly, and watch whether the door sits flush all the way around. If it still throws dE, the strongest next suspect is the dryer door switch or a worn latch/strike setup.
This code is usually pretty literal: the dryer thinks the door is open. Reality check: sometimes the door feels shut to your hand but is not fully engaging the latch. Common wrong move: slamming the door harder and cracking the strike or bending the hinge side farther out of line.
Don’t start with: Do not start by ordering a control board. On this symptom, the door closure parts and switch are far more common than the electronics.
You press Start, hear little or nothing happen, and the display quickly shows the door error.
Start here: Begin with the latch pocket, door strike, and whether the door is sitting flush against the front panel.
The dryer may start only when you hold the door closed, lift up on it, or slam it.
Start here: Check for a sagging door, loose hinge screws, or a worn dryer door strike that is not reaching the switch area cleanly.
The dryer starts, then stops mid-cycle with a door error after vibration or tumbling.
Start here: Look for a loose latch, cracked strike, or a weak dryer door switch that loses contact when the cabinet shakes.
One corner sticks out, the gap is uneven, or the door rubs when closing.
Start here: Check alignment first. A misaligned door can mimic a bad switch even when the electrical parts are fine.
This is common, easy to miss, and can keep the strike from seating all the way even though the door feels closed.
Quick check: Open the door and inspect the latch pocket with a flashlight. Pull out lint clumps by hand and wipe the area clean.
If the door sags or sits unevenly, the strike may miss the latch or barely touch it.
Quick check: Look at the gap around the door. If one side is tighter, the door drops when opened, or the strike hits off-center, alignment is the first fix.
A cracked, rounded, or loose strike will not engage the latch positively, especially if the dryer only works when slammed.
Quick check: Inspect the strike and latch area for cracks, looseness, missing plastic, or a mushy no-click close.
If the door closes squarely and the latch engages but the code stays on, the switch may not be changing state.
Quick check: Press the switch area by hand with the dryer unplugged and listen for a crisp click. No click or an inconsistent click points toward the switch.
A lot of dE calls end here. Towels caught in the opening, lint in the latch pocket, or a slightly twisted door can keep the switch from seeing closed.
Next move: If the door now closes with a solid click and the code is gone, the problem was incomplete latch engagement. If the code remains or the door still needs force, move to alignment and hardware checks.
What to conclude: The dryer only needs the door circuit to close cleanly. Anything that blocks full closure can trigger dE.
A crooked door can act exactly like a bad switch. Fix the mechanical fit before you blame the electrical parts.
Next move: If the door now shuts square and the code clears, the issue was alignment, not an electrical failure. If the door is aligned but still will not register closed, inspect the strike and latch more closely.
What to conclude: The switch can only work if the door hardware reaches it in the right position every time.
When the dryer only works after slamming, or the close feels soft instead of positive, the strike or latch is often worn.
Next move: If replacing obviously worn latch hardware restores a firm close and the code disappears, you found the fault. If the latch hardware looks sound and the door closes firmly, the next likely failure is the dryer door switch.
Once the door is closing squarely and the latch hardware looks good, the switch becomes the main suspect.
Next move: If a new dryer door switch restores normal starting and the code stays gone, the repair is confirmed. If the switch tests good and the code still remains, the problem may be in the switch wiring or control input and it is time to stop short of guesswork.
This keeps you from buying the wrong part pile. By now you should know whether the problem is closure, latch hardware, or the switch itself.
A good result: If the dryer starts normally several times in a row and no longer shows dE, the repair path was correct.
If not: If the code persists after the confirmed fix, the remaining issue is likely wiring or control-side diagnosis.
What to conclude: You want one confirmed repair, not a stack of maybe-parts.

It usually means the dryer thinks the door is open. The usual causes are a door that is not fully latching, worn latch hardware, or a bad dryer door switch.
No. That usually means the strike, latch, alignment, or switch is right on the edge. Slamming the door often makes the damage worse and can turn a small hardware repair into a bigger one.
Not usually. On this symptom, the door closure parts and the dryer door switch are much more common than a failed control board.
Vibration can shake a weak latch, worn strike, sagging door, or failing switch just enough to open the door circuit for a moment. That is why intermittent dE errors often point to hardware wear or a weak switch.
Yes. Packed lint in the latch pocket can keep the strike from seating fully. It is a simple check, but it fixes more of these calls than people expect.
Not always. If the problem is obvious lint buildup, a loose hinge, or a cracked dryer door strike, you may not need one. A multimeter helps once the door closes properly and you need to confirm the dryer door switch.
