What CL E means (lg cl e error)
An lg cl e error (Er CL) on an LG refrigerator indicates a low-side refrigerant leak in the sealed system — a serious fault. Unlike a simple sensor code, this points to refrigerant escaping, so cooling fails and the repair must be done by a technician qualified to work on sealed refrigeration systems.
Symptoms to look for
The signs below help confirm you are dealing with this condition rather than a different fault on your LG Refrigerator. You may see one of them or several together, and they can build up gradually or appear suddenly after a power event, a long door opening, or recent service.
- The display shows “CL” or “Er CL”
- The unit no longer cools properly
- The compressor runs constantly without cooling
- Food is warming throughout the unit
Common causes
Several different faults can produce these symptoms. Working through the most likely causes in order helps separate a quick, owner-level check from a problem that needs trained service and the correct LG parts.
- Low-side refrigerant leak — refrigerant is escaping the sealed system
- Damaged refrigerant line — a line or joint has failed
- Evaporator leak — a leak in the cooling coil
- Sealed-system fault — a related compressor or line problem
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where high-voltage parts, gas, the sealed refrigeration system, or a heat-pump compressor are involved, and hand the rest to a qualified technician.
- Move perishable food to another cooler appliance to protect it.
- Note when cooling started to fail so the technician has a timeline.
- Do not attempt sealed-system work — it requires trained service.
- Because a refrigerant leak stops cooling, arrange service promptly.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the sealed refrigerant system, compressor, evaporator, and refrigerant lines. The correct part for your LG Refrigerator is matched from the model and serial number, and genuine LG components are fitted rather than generic substitutes so that performance, safety, and the appliance’s long working life are all protected. Confirming the failed part before ordering avoids replacing more than the fault actually requires.
When to call a technician
CL E is a sealed-system leak that needs a technician qualified in refrigeration to locate, repair, and recharge the system. When the fix calls for trained service, book a visit through our scheduling page and an experienced, qualified technician will diagnose and repair it.

Prevention and care
Regular care keeps this condition from returning on your LG Refrigerator. Keep filters, vents, and the condenser or exhaust path clean, avoid overloading or blocking airflow, check that doors and seals close cleanly, and follow the LG maintenance guidance for your model. Because this unit relies on electronic control, protect it with a stable, correctly rated power supply and have any built-in or laundry installation done to LG specification so the control never sees an out-of-range condition. If a code appears, note exactly what was shown before you reset the appliance — that record helps the technician reach an accurate diagnosis and avoid replacing parts unnecessarily. Where stored food, a sealed refrigerant system, gas, or a safety lockout is involved, treat the condition as a reason to act quickly rather than wait.
