LG Fridge Not Cooling — First Steps
Before assuming the worst, run through these quick checks:
- Temperature settings — Ensure the fridge is set correctly. LG recommends 37°F (3°C) for the fridge and 0°F (-18°C) for the freezer.
- Demo / Showroom mode — LG fridges can accidentally enter "Demo Mode" which disables cooling entirely. Check if "OF F" is showing on the display. To exit: press and hold the REFRIGERATOR and ICE PLUS buttons simultaneously for 3 seconds.
- Door seals — Check the rubber door gaskets for cracks or gaps. A broken seal lets warm air in continuously.
- Coil clearance — Ensure the fridge has at least 2 inches of clearance on all sides for ventilation.
Common Causes of an LG Fridge Not Cooling
1. Dirty or Blocked Condenser Coils
The condenser coils (located at the back or underneath the fridge) dissipate heat from the refrigerant. When they're clogged with dust and pet hair, they can't release heat efficiently, and cooling performance drops. Clean the coils every 6–12 months with a vacuum and coil brush.
2. Evaporator Fan Motor Failure
The evaporator fan circulates cold air from the freezer into the fridge section. If this fan fails, the fridge gets warm while the freezer remains cold. Listen for: no fan noise when you open the freezer door.
3. Defrost System Problem (Very Common in LG)
LG refrigerators are particularly susceptible to linear compressor issues and defrost system failures. When the defrost heater or defrost thermostat fails, ice builds up on the evaporator coils and blocks airflow. Symptoms: freezer is cold but fridge is warm, ice/frost visible on the back wall of the freezer. See our related guide on freezer ice buildup troubleshooting.
4. LG Linear Compressor Problems
LG uses a "linear compressor" in most of their fridges, which is covered by a 10-year warranty in most markets. If your LG fridge is 5–10 years old and suddenly stops cooling, the linear compressor may have failed. This is a known issue with certain LG models, and LG has extended warranties and recall programmes in some regions. Check LG's website with your model number.
5. Refrigerant Leak
If the refrigerant (the gas that creates cold) leaks from the system, the fridge can't maintain temperature regardless of how hard the compressor works. Signs: clicking sounds, compressor running continuously, not cold at all. This requires a certified technician with refrigerant handling certification.
6. Start Relay Failure
The start relay helps the compressor kick on. A failed relay means the compressor never starts — you may hear a click every few minutes as the fridge tries and fails to start. Shake the relay: if it rattles, it needs replacing.
When to Call a Technician
Call a professional if the fridge remains warm after checking basic settings, cleaning coils, and verifying the door seals. Compressor, refrigerant, and evaporator fan repairs require specialist tools and parts. AWS Domestic Appliance Repairs services all LG refrigerators in Atlanta.

Should You Turn Your Fridge Up in Hot Weather?
Yes — during hot Atlanta summers, your refrigerator works harder to maintain temperature. If your fridge is near a hot wall, in direct sunlight, or in an uninsulated garage, you may need to lower the temperature setting by 1–2 degrees to compensate. However, if your fridge can't maintain temperature even at the coldest setting, that's a sign of a failing component — not just the heat.
