In this guide, we will discuss the troubleshooting steps that you can follow to fix your LG refrigerator if it is not cooling. A refrigerator that is not cooling can be frustrating and inconvenient, but with the right steps, you can identify and resolve the issue quickly. Whether the problem lies in a faulty compressor, condenser coils, or defrost thermostat, we will walk you through the necessary steps to get your LG refrigerator working properly once again.
Understanding the Problem
When your LG refrigerator is not cooling, it can be frustrating and worrisome. It’s important to understand the possible causes of this issue before attempting to fix it. The first thing to check is the temperature settings. Make sure the temperature is set correctly and that the air vents inside the fridge are not blocked. If the temperature is set correctly, the problem could be due to a malfunctioning part.
Common Causes of LG Refrigerator Not Cooling
- Faulty compressor
- Malfunctioning evaporator fan
- Dirty condenser coils
- Blocked air vents
- Refrigerant leak
Diagnosing the Problem
To diagnose the problem, you’ll need to start by unplugging the refrigerator and removing the back panel to access the compressor and evaporator fan. Check the compressor for any visible signs of damage or wear and tear. If the compressor is damaged, it will need to be replaced. You can also use a multimeter to test the compressor for continuity. If the compressor is not functioning correctly, it could be the cause of the problem.
Next, check the evaporator fan. The evaporator fan is responsible for circulating cold air throughout the refrigerator. If the fan is not working correctly, the fridge will not cool properly. Check the fan for any obstructions or signs of damage. If the fan is damaged, it will need to be replaced.
Checking the Condenser Coils
Dirty condenser coils can also cause the refrigerator to not cool properly. The condenser coils are located at the back of the fridge and can become clogged with dust and debris over time. To clean the coils, use a vacuum cleaner with a brush attachment to remove any dust and debris.
Checking for Airflow Issues
If the air vents inside the fridge are blocked, it can prevent cold air from circulating properly. Check the vents for any obstructions and clear them if necessary. Also, make sure that the fridge is not overloaded with food, as this can also block airflow.
Checking for Refrigerant Leaks
Finally, a refrigerant leak can cause the fridge to not cool properly. If you suspect a refrigerant leak, you’ll need to call a professional to repair it. Refrigerant leaks can be dangerous and should only be handled by a trained technician.
Fixing the Problem
Once you’ve identified the cause of the problem, you can begin to fix it. If the compressor is faulty, it will need to be replaced. If the evaporator fan is damaged or not working correctly, it will also need to be replaced. Cleaning the condenser coils and air vents can help improve airflow and cooling. If there is a refrigerant leak, it will need to be repaired by a professional.
Tips for Maintaining Your LG Refrigerator
To prevent future cooling issues, it’s important to maintain your LG refrigerator regularly. Here are some tips to help keep your fridge running smoothly:
- Clean the condenser coils at least once a year.
- Check the temperature settings regularly to ensure they are set correctly.
- Avoid overloading the refrigerator with food.
- Keep the air vents inside the fridge clear of obstructions.
- Schedule regular maintenance with a professional.
FAQs for How to Fix LG Refrigerator Not Cooling

How do I troubleshoot a faulty LG refrigerator compressor?
To troubleshoot a faulty LG refrigerator compressor, first, unplug the unit from the electrical outlet. Remove the cover from the compressor and inspect for signs of wear and tear or damage. Check the winding resistance with an ohmmeter and test the compressor relay switch. If it is malfunctioning, it may need to be replaced. If these troubleshooting steps do not identify the issue, it may be best to call a professional repair technician.
How do I clean the condenser coils on my LG refrigerator?
To clean the condenser coils on your LG refrigerator, first, unplug the unit from the electrical socket. Locate the condenser coils at the back or bottom of the refrigerator and use a soft brush or cloth to remove any dust or debris. If the coils are very dirty, a vacuum cleaner may be used, but be sure to use a brush or crevice attachment to avoid damaging the coils.
How do I check if the thermostat on my LG refrigerator is malfunctioning?
To check if the thermostat on your LG refrigerator is malfunctioning, first, unplug the unit. Locate the thermostat dial and set it to the coldest setting. Wait for roughly 20 minutes and then place a thermometer inside the unit. The temperature should be between 37°F and 40°F. If the temperature is higher, the thermostat may be faulty and need replacement.
Can a refrigerant leak be fixed on an LG refrigerator?
