Understanding the Problem
Many LG dryers display the code “dL” (or “DL”) when the machine detects the door isn’t locked or the door-lock system isn’t registering closed. When the dryer’s control board does not see the door-closed signal it will refuse to start a cycle and show dL to protect the unit and prevent operation with the door open. This code is usually a door-latch/lock or door-switch related issue but can also be caused by damaged wiring or a faulty control board. If you’re seeing “HS” instead of “dL” it may be a misread of the display (some displays can be hard to read) or a different model-specific code. If you truly see “HS,” reply with your exact model number — many LG models use different code sets. For dL, start by checking the door, latch and switch for visible damage or obstruction before replacing parts.
Common Symptoms
Dryer won’t start and displays dL (or DL); door appears to close normally but dryer acts as if door is open; intermittent starting when pressing or jiggling the door; no drum rotation or heat because cycle won’t begin.
Common Causes
- Broken or misaligned door latch or striker so the lock mechanism can’t engage
- Faulty door switch or door lock assembly that fails to register the closed state
- Damaged wiring harness or connector between the door switch/lock and the control board (or, rarely, a bad control board)

Helpful Repair Tip
Close the door firmly and try to start a cycle. If the dL code clears when you press the latch and returns when you release it, test the door switch or latch assembly with a multimeter for continuity while the door is closed to confirm the faulty part.
Frequently Asked Questions
How do I clear the dL code and get the dryer to start?
First, close the door firmly and try starting again. If that doesn’t help, disconnect power for 1–2 minutes to reset the control board. If the code returns, inspect the door latch and switch: look for broken parts, loose screws or obstruction. If you can safely access the switch, test it with a multimeter for continuity when the door is closed. Replace the door latch or switch if it fails the test.
Can I replace the door lock or switch myself, and is it expensive?
Yes — replacing a door latch or door switch is a common DIY repair that usually requires removing the front panel or door trim and swapping the part. Costs vary by model but the parts themselves are typically inexpensive; labor depends on your skill level. Always unplug the dryer before working on it and consult your model-specific service manual or a parts diagram to get the correct replacement part number.
