Quick answer
CL, CL E or E CL on an LG refrigerator indicates a leak on the low side of the refrigerant cycle.
Model compatibility: LG reuses codes across series and model years, so CL, CL E, E CL may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Low-side refrigerant leak.
If the display reads CL, CL E or E CL, your LG refrigerator is reporting a leak of refrigerant on its lower side. LG points to the evaporator as the probable source.
Background from the manual
A faulty valve is one possible cause. The code shows up once the temperature and compressor sensors give abnormal values.
Owner action
LG gives you nothing to try here. A repair service is required.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
