Er CL — (E CL) — Low-side refrigerant leak / cooling fault

Inspection code for sustained poor cooling traced to the low-pressure side. Usually a leak at the evaporator or suction line, sometimes accompanied by frost/icing and higher-than-normal compressor amperage.

How to fix it

  1. Check ventilation, door seals, and that thermostat settings are correct — rule out non-sealed causes.
  2. This code requires a sealed-system tech (EPA 608) to diagnose properly.
  3. If covered by LG's 10-year linear compressor warranty (2014–2022 US units), file a claim first.
  4. Tech will leak-detect, repair (often evaporator replacement), evacuate and recharge.
  5. Code self-clears after 24 hours of normal cooling, or force-clear with Freezer + Refrigerator 3× door open.

Why it happens

Typical signs: Er CL or E CL on display · Frost or icing on suction line · Compressor runs hot, higher amp draw · Both compartments warming over time · Evaporator partially frosted

  • Evaporator leak Pinhole in aluminum evap from corrosion.
  • Suction-line leak Vibration crack or rubbed-through tube.
  • Valve failure (multi-evap) Stuck valve restricts return flow.
  • Weak compressor suction Linear compressor with worn piston.
