Identify the symptom first; it will guide the rest of the repair process.

Tools and Parts You’ll Need

• Phillips and flat‑head screwdrivers
• Adjustable wrench set
• Replacement door seal (matching model)
• Replacement InstaView glass panel (OEM or certified third‑party)
• Replacement backlight LED strip (specific to GLSS320SSS)
• Replacement electronic control board (if needed)
• New hinges or hinge bolts (if worn)
• Utility knife (for seal removal)
• Safety glasses

Step‑by‑Step Repair

1. Inspect the Door Seal

• Lift the door and look for cracks, tears, or missing rubber.
• If the seal is damaged, slide a utility knife along the seam to remove old adhesive.
• Clean the surface with mild soap and water; dry thoroughly.
• Install the new seal, starting at the top and working downward.
• Press firmly and seal any gaps with a rubber squeegee.

2. Replace a Broken Glass Panel

• Carefully remove the broken glass. Hold the frame with a cloth to avoid injury.
• Set the new panel in place; it should snap into the frame.
• Check that the edges are seated evenly.
• If the frame has been damaged, replace it before reinstalling the panel.

3. Tighten or Replace Hinges

• Use the adjustable wrench to check all hinge screws.
• Tighten any loose screws; replace bolts if they show signs of rust.
• If a hinge is bent or broken, replace it with an identical part.

4. Address the InstaView Backlight

• Unplug the refrigerator and locate the backlight strip behind the glass.
• Remove the strip with a screwdriver; note its orientation.
• Install a new strip, aligning the connector pins.
• Test the light before closing the door.

5. Repair the Electronic Control Board

• Power the refrigerator again and navigate to the diagnostic mode (refer to the owner’s manual for the code).
• If a specific error code appears, look it up in the service manual.
• Disconnect the board, remove it, and replace it with the new one.
• Reconnect all cables securely.

6. Check the Compressor and Refrigerant System

• If the fridge is not cooling, inspect the compressor for signs of wear (noise, heat).
• Verify that the condenser coils are clean; vacuum them if necessary.
• A refrigerant leak may require a professional technician.

7. Final Test

• Close all doors and set the temperature to a standard setting (around 37°F/3°C).
• Wait 24 hours to allow the system to stabilize.
• Verify that the InstaView feature operates smoothly and that the fridge cools evenly.

Cleaning and Maintenance Tips

• Clean the condenser coils every 6 months; dust buildup reduces efficiency.
• Check the door seal quarterly; wipe with a damp cloth.
• Avoid placing heavy objects on the door; this can crack the glass.
• Keep the interior light on for 30 minutes after the fridge is turned on; this warms up the interior and improves cooling efficiency.

When a Professional Is Needed

• Refrigerant leaks: Only a licensed technician can safely handle refrigerant.
• Compressor failure: Requires a certified appliance repair service.
• Complex electronic issues: If the diagnostic codes point to deeper hardware problems.
• Warranty service: Contact LG support before making any self‑repair if your unit is still under warranty.
