LG Refrigerator CH Error Code – What It Means and How to Fix It

Introduction

Seeing the CH error code on your LG refrigerator? Don’t ignore it — this code indicates a sealed system issue, which can seriously affect cooling and long-term performance. At Lex Appliance Repair, we specialize in diagnosing and fixing problems like this quickly and professionally. Whether you’re located in Reseda, Canoga Park, Encino, or nearby, here’s everything you need to know about the CH error and how to handle it.

What Does CH Mean on an LG Fridge?

The CH error code on an LG refrigerator stands for Sealed System Error. This means the fridge is detecting a malfunction in the closed-loop cooling circuit — typically involving refrigerant pressure, a failing compressor, or a bad sensor. Some sources may refer to it as “CH” or even “CL” on certain models, but “CH” is the actual code displayed on most LG units.

The error shows up when the refrigerator fails to cool properly due to weak load detection or poor refrigerant circulation. If not addressed, it can result in food spoilage and long-term system damage.

Common Causes of the CH Error

At Lex Appliance Repair, we’ve seen this issue arise from several root causes:

  • Refrigerant leak inside the sealed system
  • Compressor malfunction or low amp draw
  • Faulty defrost sensor or internal sensor misreadings
  • Contaminants or moisture inside the sealed tubing
  • Restricted capillary lines or failed control valve

Our licensed technicians use pressure gauges, electrical testing, and refrigerant analysis to pinpoint the exact fault.

How to Clear the CH Error (The Right Way)

  1. Do not reset the code unless the system is repaired.
  2. After fixing the sealed system (like sealing a leak or replacing the compressor), many LG fridges automatically clear the CH code once the freezer reaches −10°F (−23°C).
  3. If the code doesn’t clear, on certain models, it can be manually reset by pressing “Freezer” and “Refrigerator” buttons three times with the door open.
  4. However, clearing the code won’t fix the underlying problem — it will likely return unless the root cause is corrected by a professional.
