How do I fix error code E CL on a LG refrigerators?

1. undefined: Use LG SVC App Step 1 to measure evaporator temperature and determine if this is a sealed system problem or customer misuse. 2. undefined: If temperature shows normal operation: check PCB voltage — if PCB voltage is abnormal, replace Main PCB. 3. undefined: Use SVC App Step 2 to measure high/low side pressure and recovery time. If recovery time is more than 15 minutes: system is restricted. Proceed to restriction check. 4. undefined: Check equilibrium pressure. If equilibrium pressure is more than 20 psi: compressor is defective — replace compressor. 5. undefined: If equilibrium pressure is 20 psi or less: refrigerant is leaked — locate and repair leak. 6. undefined: Charge system with nitrogen (N2) for pressure test. Check low-pressure parts (evaporator, suction pipe) using bubble test or refrigerant leak detector first. 7. undefined: If leak is found on low-pressure side: replace leaking part plus both drier and compressor (low-pressure side is below atmospheric pressure during leak, so moisture has likely entered). 8. undefined: If no leak found on low-pressure side: check high-pressure parts (condenser, drier). 9. undefined: If leak is found on high-pressure side: replace leaking part plus drier. 10. undefined: If leak location cannot be found: install UV drier and recheck at next service visit. 11. undefined: After sealed system repair: error code will disappear automatically when freezer temperature drops to 14°F or below.

How to Fix

1
Use LG SVC App Step 1 to measure evaporator temperature and determine if this is a sealed system problem or customer misuse.
2
If temperature shows normal operation: check PCB voltage — if PCB voltage is abnormal, replace Main PCB.
3
Use SVC App Step 2 to measure high/low side pressure and recovery time. If recovery time is more than 15 minutes: system is restricted. Proceed to restriction check.
4
Check equilibrium pressure. If equilibrium pressure is more than 20 psi: compressor is defective — replace compressor.
5
If equilibrium pressure is 20 psi or less: refrigerant is leaked — locate and repair leak.
6
Charge system with nitrogen (N2) for pressure test. Check low-pressure parts (evaporator, suction pipe) using bubble test or refrigerant leak detector first.
7
If leak is found on low-pressure side: replace leaking part plus both drier and compressor (low-pressure side is below atmospheric pressure during leak, so moisture has likely entered).
8
If no leak found on low-pressure side: check high-pressure parts (condenser, drier).
9
If leak is found on high-pressure side: replace leaking part plus drier.
10
If leak location cannot be found: install UV drier and recheck at next service visit.
11
After sealed system repair: error code will disappear automatically when freezer temperature drops to 14°F or below.
