Refrigerator not cooling

Protect perishable food first. Then check settings, airflow, doors, and the installation environment before assuming a sealed-system failure.

Food safety first

Move perishables if temperatures are unsafe.

Do not rely on how cold food feels. Use a refrigerator thermometer and follow your local food-safety guidance.

External checks

  1. 1
    Confirm the set temperature

    Check that cooling was not changed or placed in demo/vacation mode.

  2. 2
    Clear internal air vents

    Overpacked shelves can prevent cold air from circulating.

  3. 3
    Inspect the door closure

    Packaging or a dirty seal can hold the door slightly open.

  4. 4
    Check ventilation around the unit

    Follow the clearances and cleaning procedure in the model manual.

Cross-checked: LG's current support flow starts with temperature settings, food arrangement, and clearing air vents.

When professional service is likely

If lights work but neither compartment cools after the external checks, or you hear repeated clicking, see an error code, or find oil-like residue, avoid sealed-system work and arrange qualified service.
