LG Refrigerator Not Cooling?
If your LG refrigerator isn't cooling, don't panic. Most cooling issues have straightforward causes you can check yourself before calling a tech.
Always unplug the refrigerator before cleaning condenser coils or inspecting fans. Wait 5 minutes after unplugging before touching any components.
Step-by-step troubleshooting
Make sure the temperature is set to 37°F for the fridge and 0°F for the freezer. Someone may have accidentally bumped the controls. On models with a digital panel, press and hold the Refrigerator button to confirm the setpoint.
Dusty coils are the #1 cause of cooling problems on LG fridges. Pull the unit away from the wall and vacuum the coils on the back or underneath (some LG models have bottom-mounted coils behind a kick plate). Do this every 6 months.
With the fridge pulled out, listen for the condenser fan running near the compressor. If it’s not spinning, check for debris around the blade. If the motor itself is dead, the compressor will overheat and shut off.
Open the freezer and listen for the evaporator fan. On LG models, the fan is behind the rear panel inside the freezer. If the freezer is cold but the fridge section isn’t, the evaporator fan motor has likely failed.
Heavy frost or ice on the back wall of the freezer means the defrost system has failed. LG refrigerators are known for defrost heater and bimetal thermostat failures. This blocks airflow and prevents cooling in the fresh food section.

When to call a professional
If the compressor clicks on and off repeatedly, or if you hear a buzzing noise from the back, the compressor or start relay may be failing. LG compressors have been subject to a class-action settlement — check if your model is covered before paying for a repair.
