What CL E / Er CL means

CL E, E CL, or Er CL on an LG refrigerator with an LED or LCD display reports a refrigerant leak on the low side, at the evaporator. The newer description matches Er CH: insufficient cooling or an abnormal internal temperature caused by low refrigerant, a leak, a compressor or valve problem, a blockage, or doors left open. CL alone on other LG appliances means child lock, so the leak meaning applies only when CL is shown with E or Er.

Common causes of CL E / Er CL

Door gaskets and doors left ajar
Low refrigerant or an evaporator leak
Compressor, valve, or blockage affecting cooling

✓ One safe check you can try

1. Close both doors fully and clear anything holding them open. 2. Unplug the refrigerator for 5 minutes and restart it. 3. After a repair, allow 24 hours for temperatures to settle. 4. Keep the doors shut as much as you can and protect perishables. 5. If the code stays, request service.

! Why to stop there

The code cannot tell us whether the cause is a leak, a blockage, or a compressor problem.
We inspect cooling performance before quoting and give a written price first.
Any sealed-system work is explained to you before it starts.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

CL E / Er CLCL E / Er CL questions

Does CL on another LG appliance mean the same thing?

No. CL alone on other LG appliances is child lock, a user setting. On a refrigerator, the leak meaning applies when CL appears together with E or Er, such as CL E or Er CL.

Is CL E the same as CH E?

They share the same cause list, but CL E points to the low side, at the evaporator, and CH E to the high side, at the condenser. We check both areas during one visit and explain which one applies.

What should I do with my food?

Keep the doors closed and check temperatures. If the fresh-food or freezer section warms, move perishables to a cooler while you arrange the inspection, and tell us how long the code has been showing.
