Top maintenance tips

While changing your LG refrigerator water filter is paramount for cleaner drinking water, a few other maintenance tips can help ensure your appliance continues to perform optimally and provide a healthy environment for your family.

  • Refrigerator Air Filters:

    "Do I really need to change my refrigerator air filter?" If your LG refrigerator is equipped with an air filter (often called a Fresh Air Filter or Pure N Fresh filter), the answer is yes. These filters are designed to circulate air within the fresh food compartment to remove odors and help keep food fresher for longer. Like water filters, they become saturated over time and should typically be replaced every six months. Check your manual for specific replacement intervals and instructions.

  • Cleaning the Water Dispenser Nozzle:

    "How to clean LG fridge water dispenser filter?" While there isn't a separate "filter" in the dispenser nozzle itself, the nozzle can accumulate mineral deposits or residue over time. Regularly wipe down the dispenser area and use a small brush (like a clean toothbrush) or a cotton swab to clean the inside and outside of the dispenser nozzle. This ensures hygienic dispensing and prevents blockages.

  • General Refrigerator Cleaning:

    Regularly clean the interior and exterior of your LG refrigerator. Wipe down shelves, drawers, and door seals with a mild, food-safe cleaner. This prevents food spills from becoming breeding grounds for bacteria and helps maintain a fresh environment for your groceries.

  • Condenser Coils:

    For optimal energy efficiency and cooling performance, it's good practice to clean the condenser coils (usually located at the back or underneath your refrigerator) once or twice a year. Refer to your owner's manual for specific instructions on how to access and clean them safely.
