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

1. undefined: Use LG SVC App jig if available to determine if issue is compressor or sealed system; if no jig, use temperature gun 2. undefined: Check voltage to determine if it is a PCB problem 3. undefined: Measure high-pressure side (drier) and low-pressure side (compressor processing pipe) pressure 4. undefined: Check equalization return time: if clogging, equalization takes more than 15 minutes 5. undefined: Check equalized pressure to confirm sufficient refrigerant and diagnose compressor vs. leak 6. undefined: If refrigerant is low, perform leak test using refrigerant or nitrogen gas 7. undefined: Check low-pressure parts for leaks: evaporator, suction pipe 8. undefined: If no low-pressure leaks, check high-pressure parts: condenser, drier 9. undefined: After sealed system repair, error code clears automatically when freezer temperature drops to 14F or below 10. undefined: On follow-up visit, check for leaks using UV dye in drier

Error Code E CL

Low Side Cycle Leakage (Refrigerant Leak or Sealed System Problem)

Moderate

Address soon - your appliance may not work properly

What This Means

Low-side refrigerant leak (evaporator, suction pipe); Partial or complete restriction in low-side sealed system; Compressor fault; Extended door-open time causing apparent low-side issue

How to Fix

1
Use LG SVC App jig if available to determine if issue is compressor or sealed system; if no jig, use temperature gun
2
Check voltage to determine if it is a PCB problem
3
Measure high-pressure side (drier) and low-pressure side (compressor processing pipe) pressure
4
Check equalization return time: if clogging, equalization takes more than 15 minutes
5
Check equalized pressure to confirm sufficient refrigerant and diagnose compressor vs. leak
6
If refrigerant is low, perform leak test using refrigerant or nitrogen gas
7
Check low-pressure parts for leaks: evaporator, suction pipe
8
If no low-pressure leaks, check high-pressure parts: condenser, drier
9
After sealed system repair, error code clears automatically when freezer temperature drops to 14F or below
10
On follow-up visit, check for leaks using UV dye in drier
