What does dE mean on a LG dryer?

dE means: Door open error. The most likely parts involved are door switch, door latch.

How much does it cost to fix dE?

A typical no-power repair (door switch / fuse / control board) costs about $100–$350 nationally, parts and labor included. This is a reference range, not a quote — local prices vary.

Can I bypass the door switch to keep using my dryer?

No. The door switch is a safety part that stops the drum when the door opens. Bypassing it can lead to injury, so replace the failed part instead.

Why does the dE code come and go?

A switch or latch that is starting to wear out may work some of the time and fail at other times. A door that does not always latch fully can cause the same thing. If the code keeps coming back, the part likely needs replacing soon.

LG Dryer dE Error Code

Door open error

Applies to: All digital display models.

What's going on

The dE code on an LG dryer means the dryer thinks the door is open, so it will not start or keep running. Often the door is just not fully shut or something is blocking it. If the door closes firmly and the code stays, the door switch or door latch has likely failed.

Your dryer uses a door switch to sense when the door is closed. When you shut the door, the latch or a tab on the door presses the switch. This tells the control that it is safe to tumble and heat.

If the switch does not get pressed, or it is worn out and stops sending the right signal, the dryer shows dE and refuses to run. This is a safety feature. It keeps the drum from spinning while the door is open.

This code shows up on all LG dryers with a digital display. Code meanings can change between model generations, so confirm with your model number in your owner's manual.

Likely causes

door switch — The switch can wear out, stick, or stop making contact inside. Then the dryer reads the door as open even when it is shut.
door latch — A worn, loose, or broken latch may not hold the door tight enough to press the switch. The door may look closed but still not be fully latched.

The same code can mean different things on different model generations. Check the model number on your dryer's rating plate before ordering parts.

Can you fix it yourself?

Doable for an experienced DIYer with the right part, but many people still call a technician.

Safe things to check first

Open the door and close it again firmly until you feel or hear it latch. Then try starting a cycle.
Look around the door opening and the door seal for clothing, lint, or other items that could keep the door from closing all the way.
Look at the latch and the catch on the door for obvious damage, like a cracked or bent piece. Do not take anything apart.
Unplug the dryer or switch off its breaker for a few minutes, then restore power and try again. Always unplug the dryer or switch off its breaker before touching anything inside it.

When to call a technician

If the door closes firmly and the dE code still appears, the door switch or latch probably needs replacing. A handy owner could do this with the right part for their model, but call a qualified appliance technician if you are not comfortable working on the dryer.
