As a homeowner, there's nothing more frustrating than discovering that your LG fridge is not cooling properly. The last thing you want is spoiled food and a potentially expensive repair bill. However, before you panic, it's important to troubleshoot the issue and explore potential solutions. In this article, we'll provide step-by-step instructions on how to troubleshoot an LG fridge not cooling, as well as offer tips for preventing future issues.
Causes
A list of the most common causes of an LG fridge not cooling:
- Dirty or clogged condenser coils: Over time, the condenser coils on your LG fridge can become dirty or clogged with dust and debris, which can prevent the fridge from cooling properly.
- Malfunctioning thermostat: The thermostat is responsible for regulating the temperature inside your fridge. If it is not working correctly, the fridge may not cool properly.
- Faulty evaporator fan: The evaporator fan is responsible for circulating cold air throughout the fridge. If it is not working, the fridge may not cool properly.
- Defective compressor: The compressor is responsible for compressing the refrigerant and circulating it through the fridge's cooling system. If it is not working properly, the fridge may not cool at all.
- Low refrigerant level: If the refrigerant level in your LG fridge is too low, it can cause the fridge to stop cooling properly.
- Damaged door gaskets: If the door gaskets on your fridge are damaged or worn out, they may allow warm air to enter the fridge, which can prevent it from cooling properly.
- Blocked air vents: If the air vents inside your LG fridge are blocked by food or other items, it can prevent cold air from circulating properly.
These are some of the most common causes of an LG fridge not cooling. It's important to have a professional appliance engineer diagnose the specific problem with your fridge to determine the appropriate troubleshooting and repair solutions.

Step-by-step instruction
Here is a step-by-step guide on how to troubleshoot an LG fridge that is not cooling:
- Check the power source: Make sure the fridge is plugged in and the power source is working. Check that the circuit breaker or fuse is not tripped.
- Check the thermostat: Make sure the thermostat is set to the correct temperature. If the temperature is too high or too low, it can cause the fridge to not cool properly.
- Check the condenser coils: The condenser coils are located at the back of the fridge. Make sure they are clean and free from dust and debris. If they are dirty, use a vacuum or a brush to clean them.
- Check the evaporator fan: The evaporator fan is located in the freezer compartment. Open the freezer and listen for the sound of the fan. If it is not running, it may need to be replaced.
- Check the compressor: The compressor is located at the back of the fridge. If it is not running, it may need to be replaced.
- Check the defrost system: If the fridge is not cooling properly, it may be due to a problem with the defrost system. Check the defrost heater, defrost thermostat, and defrost timer to see if they are working properly.
- Check for blockages: Make sure there are no blockages in the air vents or the door gaskets. Blockages can prevent cold air from circulating properly and cause the fridge to not cool properly.
- Check the seals: Make sure the door gaskets are sealing properly. If they are damaged or worn, they may need to be replaced.
- Consult the manual: Refer to the owner's manual for your LG fridge to troubleshoot specific error codes or to find more information on common issues that may be causing your fridge to not cool properly.
If you are unable to identify the problem or if you are unsure about how to troubleshoot the fridge, it's best to seek assistance from a professional appliance engineer. They can diagnose the problem and recommend the appropriate repair solutions.
If nothing helped
If you have tried all the troubleshooting steps and the LG fridge is still not cooling properly, here are some alternative solutions that you can try:
-
Check the warranty: If the fridge is still under warranty, contact LG or the retailer where you purchased the fridge. They may offer a repair or replacement for free or at a reduced cost.
- Contact an appliance repair service: If the fridge is out of warranty, contact a professional appliance repair service. They can diagnose the problem and recommend the appropriate repair solutions.
- Consider a replacement: If the fridge is old and the cost of repairs is high, it may be more cost-effective to replace the fridge. Look for Energy Star certified models that are energy-efficient and have a low environmental impact.
- Adjust the temperature settings: In some cases, adjusting the temperature settings can help the fridge cool more effectively. Try lowering the temperature by a few degrees and see if that helps.
- Consider moving the fridge: If the fridge is located in a spot where it is exposed to heat or sunlight, consider moving it to a cooler spot. Keep it away from heat sources, such as ovens or heaters, and make sure there is adequate ventilation around the fridge.
Remember that troubleshooting a fridge can be a complex process, and it's important to seek the assistance of a professional if you are unsure about how to proceed.
Tips
Here are some tips to help you avoid LG fridge issues in the future:
- Regularly clean the condenser coils: Dust and debris can accumulate on the condenser coils, causing the fridge to work harder and potentially overheat. Clean the coils at least twice a year to keep them free from dirt and dust.
- Keep the fridge at the right temperature: Set the fridge temperature between 37°F and 40°F (3°C to 4°C), and the freezer temperature between 0°F and 5°F (-18°C to -15°C). Keeping the fridge at the right temperature will help prevent food spoilage and avoid strain on the fridge.
- Avoid overloading the fridge: Overloading the fridge can cause it to work harder and may also block airflow, leading to cooling issues. Keep the fridge organized and avoid overcrowding it.
- Keep the door seals clean: The door seals help keep cold air inside the fridge, so it's important to keep them clean and free from debris. Clean the seals with a damp cloth regularly.
- Avoid putting hot or warm food in the fridge: Putting hot or warm food in the fridge can cause it to work harder and may also raise the temperature of the fridge. Let food cool down to room temperature before putting it in the fridge.
- Check the fridge's level: If the fridge is not level, it may cause cooling issues. Use a spirit level to check that the fridge is level and adjust the feet if necessary.
- Don't block the air vents: Air vents are located inside the fridge and help circulate cool air. Make sure the vents are not blocked by food or containers.
- Regularly defrost the freezer: If the freezer has a lot of ice buildup, it can cause cooling issues. Defrost the freezer at least once a year to keep it running efficiently.
By following these tips, you can help prevent LG fridge issues in the future and extend the lifespan of your appliance.
