Inner wall of the refrigerator cracked

Cracks in the Inner Wall Panel

There is no radical temperature change inside a refrigerator on account of LG innovative ultra-thin effective insulation.
If, however, the inner wall panel is impacted by severe cold, a crack in the liner may result.
Cracks made on the refrigerator inner wall panel liner can also be attributed to drastic temperature change.

Cause and Symptoms

Cracks can occur in the plastic materials of the refrigerator compartment inner walls due to sudden temperature fluctuation.
However, smaller size polyurethane insulation foam known as LG proprietary “Thin Insulation Technology” is engineered and designed as superior airtightness.
As such, it prevents any dramatic change in temperature between the inside of the refrigerator and the ambient room air and won't let a crack in the inner wall panel affect refrigerator's performance

Fixing wall panel liner

➔ Fine cracks inside will not affect much if any. However, the product may get deformed over a long period of time. Small cracks can easily be covered with “Liner Tape”.
If there is no abnormality in refrigeration/freezing, your refrigerator is operating normally. Don’t worry and continue to run your machine.
If you are worried about a crack that has formed inside the refrigerator, contact LG Service for an inspection by a service technician.
