CL
LG Dryer
Severity: MinorWhat Does This Error Mean?
The CL indicator on your LG dryer means the Child Lock feature is turned on. This is not an error — it is a deliberate lock that prevents children from changing settings or starting the dryer. All buttons are disabled while CL is active. You need to deactivate Child Lock to use the dryer normally again.
Affected Models
- DLEX3900W
- DLGX3901V
- DLEX5500V
- DLE3500W
- Most LG front-load and top-load dryers
Common Causes
- Child Lock was activated intentionally using the button combination
- Someone accidentally held the wrong button combination and activated Child Lock
- The control panel was wiped down and a button was held too long
- A child pressed and held buttons on the control panel
- The dryer was moved or jostled and a button was held during transport
How to Fix It
-
Locate the Child Lock button or button combination on your model.
On most LG dryers, press and hold the 'Child Lock' button for 3 seconds. On some models it may be labeled with a lock icon.
-
Hold the Child Lock button for 3 seconds until CL disappears from the display.
You should hear a beep and the CL indicator will turn off. All buttons will then work normally.
-
If your model has no dedicated Child Lock button, check the user manual for the correct button combination.
Some LG models use a combination like holding 'Temp' + 'Dry Level' simultaneously for 3 seconds.
-
If CL won't turn off, unplug the dryer for 30 seconds, then plug back in.
A power reset can clear a stuck Child Lock state on some models.
-
Retry the Child Lock deactivation after the reset.
If CL reappears on its own after being cleared, the control panel or board may need inspection.
When to Call a Professional
Child Lock is not a fault and does not require a technician. If following the unlock steps does not work, and the panel remains unresponsive, the control board may have a fault. A technician can diagnose a faulty control board for $80–$150 in labor.
Frequently Asked Questions
Is CL on an LG dryer an error code?
No — CL is not an error. It stands for Child Lock and is a safety feature. It disables all control panel buttons so children cannot change settings or start the dryer. Deactivate it by holding the Child Lock button for 3 seconds.
Why does my LG dryer keep going into Child Lock mode?
If CL activates on its own repeatedly, it usually means a button is stuck or the control panel membrane is faulty. A stuck button that's held for too long can trigger Child Lock. Inspect the panel for any physically stuck buttons.
Where is the Child Lock button on my LG dryer?
The location varies by model. Look for a button with a lock icon or text that says 'Child Lock'. On some older LG models, it's a secondary function of another button. Your model's user manual will have the exact button combination.
