Lg Refrigerator: filter replacement needed

Professional Repair Guide

What is this symptom?

If your LG refrigerator shows a 'Replace Filter' light, it likely means the water filter needs to be replaced or the indicator hasn't been reset. This common issue occurs after about six months of use. Properly replacing the filter and resetting the indicator will restore normal operation and ensure clean water and ice.

  • Filter has reached its recommended lifespan
  • Improper installation of the filter causing inefficiency

User Suggested Solutions

  1. Locate the carbon air filter compartment, typically found in the refrigerator section. Remove the old filter by twisting it counterclockwise. Insert the new filter by aligning it properly and twisting it clockwise until secure. Run the refrigerator for a few hours to ensure proper airflow.

  2. If the filter is not fitting properly, check the installation instructions provided with the filter. Ensure that the filter is compatible with your LG refrigerator model. If necessary, consult the user manual for specific installation guidance.

  3. If you continue to experience issues after replacing the filter, check for any blockages in the air vents and ensure that the refrigerator is not overstuffed, which can restrict airflow. Clean the vents if necessary.
