What Does Error CHE Mean?

The LG Refrigerator CHE error indicates a compressor overheating issue, leading to degraded cooling performance. This may manifest as unusual humming sounds and a warm interior. The error suggests potential problems in the sealed refrigeration system, including refrigerant leaks or compressor malfunctions. If you notice the CHE code or E CH on the control panel, it's crucial to address the cooling inconsistency promptly to avoid further damage.

Common Symptoms:

  • Error code display CHE or E CH on control panel
  • Reduced cooling performance or temperature defect detected after extended runtime
  • Potential inconsistent or no cooling in refrigerator/freezer compartments

Possible Causes

  • Sealed system high‑side refrigerant issue (leak or pressure abnormality) (medium)
  • Compressor or sealed circuit component malfunction (medium)

How to Fix Error CHE

DIY Fix Basic Verification and Power Reset

  1. Check that refrigerator doors are properly closed and not left open for long periods.
  2. Ensure stable power supply; try resetting power by unplugging the refrigerator for ~5 minutes and then plugging it back in to see if the error recurs.

Technician Only Professional Diagnosis and Sealed System Repair

  1. Perform sealed system pressure and refrigerant leak testing with appropriate gauges.
  2. Inspect compressor, high‑side/low‑side pressure conditions and control valves.
  3. Repair or replace failed sealed system components (e.g., refrigerant lines, compressor, valves, sensors) and recharge refrigerant to specification.
  4. Verify cooling recovery and that CHE error no longer appears.

Parts needed: Refrigeration sealed system components (compressor, refrigerant lines, valves), Sensors related to cooling and temperature, Control board if communication faults are present

🛑 When to Call a Pro:
  • Error persists after power reset or simple checks
  • Refrigerator/freezer temperatures remain above set points
  • Unusual noises from compressor or insufficient cooling
