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. 1

    Use LG SVC App jig if available to determine if issue is compressor or sealed system; if no jig, use temperature gun

  2. 2

    Check voltage to determine if it is a PCB problem

  3. 3

    Measure high-pressure side (drier) and low-pressure side (compressor processing pipe) pressure

  4. 4

    Check equalization return time: if clogging, equalization takes more than 15 minutes

  5. 5

    Check equalized pressure to confirm sufficient refrigerant and diagnose compressor vs. leak

  6. 6

    If refrigerant is low, perform leak test using refrigerant or nitrogen gas

  7. 7

    Check low-pressure parts for leaks: evaporator, suction pipe

  8. 8

    If no low-pressure leaks, check high-pressure parts: condenser, drier

  9. 9

    After sealed system repair, error code clears automatically when freezer temperature drops to 14F or below

  10. 10

    On follow-up visit, check for leaks using UV dye in drier
