Diagnostic and troubleshooting steps

Is your LG refrigerator freezer not freezing while the fridge stays cold? This step-by-step guide covers everything from airflow issues to control board malfunctions, offering practical solutions and when to seek professional help.

Diagnostic & Troubleshooting
Inspect Air Vents

Step 1:

Inspect Air Vents

  • Ensure the air vents between the fridge and freezer are clear of obstructions. 
  • Move food items away from the vents to allow proper airflow.
Check the Evaporator Fan

Step 2:

Check the Evaporator Fan

  • Open the freezer and listen for the evaporator fan motor. If you don’t hear the fan running, it may need to be repaired or replaced.
Clean the Condenser Coils

Step 3:

Clean the Condenser Coils

  • Unplug the refrigerator and locate the condenser coils, typically found at the back or bottom of the unit. 
  • Use a vacuum or coil-cleaning brush to remove dirt and debris.
Test the Door Seal

Step 4:

Test the Door Seal

  • Close the freezer door on a piece of paper and try to pull it out. 
  • If the paper slides out easily, the gasket may need to be cleaned or replaced to ensure a proper seal.
Check for Ice Build-Up

Step 5:

Check for Ice Build-Up

  • If frost is visible on the back panel of the freezer, it could indicate a defrost system issue.
  • Manually defrost the freezer by unplugging the unit and letting it thaw completely.
Adjust the Temperature Settings

Step 6:

Adjust the Temperature Settings

  • Ensure the freezer is set to the correct temperature, typically between 0°F and -10°F.
  • Avoid setting it too high, as this can prevent freezing.
Examine the Start Relay

Step 7:

Examine the Start Relay

  • If you suspect the compressor isn’t running, test the start relay for continuity using a multimeter. Replace it if it’s defective.

Key actions for homeowners:

  • Vacuum the condenser coils every 6–12 months to prevent dirt build-up that can impact cooling performance.
  • Inspect and clean the freezer door gasket regularly to ensure a tight seal. Replace the gasket if it shows signs of wear.
  • Avoid overloading the freezer as it can block airflow and strain the cooling system. Keep the vents clear and maintain an even distribution of items.
  • Ensure the freezer temperature remains between 0°F and -10°F to avoid freezing issues.
  • Change the refrigerator’s water filter every six months to maintain proper water flow and avoid ice-related issues.

Most common repairs needed to fix a lg refrigerator freezer

When your freezer won’t freeze ice but is cold, certain repairs are more commonly required than others. Below are the most frequent fixes:

    • Replace the Evaporator Fan Motor: The evaporator fan motor circulates cold air from the freezer to the refrigerator. If it's faulty or not running, it needs replacement to restore proper airflow.
    • Repair Air Damper: The air damper controls the flow of cold air between the fridge and freezer compartments. If it’s stuck or broken, it may need adjustment or replacement.
    • Replace Thermistor: A defective thermistor sends incorrect temperature readings to the control board, disrupting the cooling cycle. Replacing the thermistor restores temperature regulation.

Frequently Asked Questions

  • Why is my LG refrigerator freezer not freezing while the fridge is cold?

    This issue is often caused by restricted airflow between the freezer and fridge compartments. Common culprits include a malfunctioning evaporator fan motor, a clogged air damper, or frost buildup on the evaporator coils due to a faulty defrost system.

  • Can I fix my LG refrigerator freezer that’s not freezing on my own?

    Some simple fixes, like cleaning dirty condenser coils or checking for obstructions in the vents, can be done by homeowners. However, more complex repairs, such as replacing the evaporator fan motor or compressor, may require professional assistance.

  • How can I prevent my LG freezer from losing its cooling efficiency?

    Regular maintenance, such as cleaning condenser coils, checking the door seals, and ensuring proper airflow inside the compartments, can prevent cooling issues. Avoid overloading the freezer, as it can obstruct air circulation.

  • Is it expensive to repair an LG freezer that’s not freezing?

    Repair costs depend on the root cause of the problem. Minor repairs, like replacing a thermistor or cleaning coils, are generally affordable, while major repairs, such as replacing the compressor or control board, can be more costly. A professional diagnosis can provide a better estimate.Repair costs depend on the root cause of the problem.
