Er CL Critical Hard — consider a tech

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

LG Refrigerator · Error code Er CL

What Er CL Means

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.

Symptoms

  • 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

Common Causes

1
Evaporator leak

Pinhole in aluminum evap from corrosion.

2
Suction-line leak

Vibration crack or rubbed-through tube.

3
Valve failure (multi-evap)

Stuck valve restricts return flow.

4
Weak compressor suction

Linear compressor with worn piston.

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.
