Direct answer
On the covered LG refrigerator, CL means a refrigerant leak on the LOW pressure side — LG's own wording. LG states it can be caused by a faulty valve, and appears when the temperature and compressor sensors show abnormal values. First, record the code and how the compartments are actually performing.
Definition versus diagnosis
The display names a detected condition—not an automatically failed part.
What this covers
- LG refrigerator covered by the cited source
- Displayed code or documented alias: CL
- The exact operating state described by the manufacturer
What it does not cover
- ×Another product type or original-manufacturer platform
- ×A visually similar but different code
- ×Internal live electrical, sealed-system, gas, battery-cell or control-board repair
Match every character and the exact product
ReversiblePhotograph the complete display and product label. This record covers CL on LG French-door, side-by-side, bottom-freezer and top-freezer refrigerators; display format and available customer checks vary by model.
Preserve the failure state
ReversibleRecord the code and how the compartments are actually performing. Record the operating stage, recent change and what still works before clearing the message.
Correct only the documented fault domain
ReversibleA refrigerant leak is not a customer repair. LG directs this to service. Do not borrow a reset or meaning from a similar code, product or model year.
Verify once, then respect the service boundary
ReversibleRepeat only the shortest safe action that reaches the original stage. If CL returns, stop repeated resets and use model-specific manufacturer support.

What does CL mean on a LG refrigerator?+
a refrigerant leak on the LOW pressure side — LG's own wording. LG states it can be caused by a faulty valve, and appears when the temperature and compressor sensors show abnormal values.
Can I reset CL without fixing the cause?+
A reset may hide the display temporarily but does not correct the documented fault. Record the code and complete only the safe checks first.
Why is the complete model number required?+
Manufacturers reuse characters across platforms. The model number determines which official table, controls and service boundary apply.
When should I stop?+
Sealed-system and refrigerant work is licensed work. Do not open the sealed system.
