How To Diagnose And Repair An Lg Refrigerator That’s Not Cooling: A Comprehensive Guide

A malfunctioning refrigerator can be a major inconvenience, especially during the hot summer months. If your LG refrigerator has stopped cooling, it’s important to identify the root cause and address it promptly to prevent food spoilage. This comprehensive guide will provide you with step-by-step instructions on how to repair an LG refrigerator not cooling, covering common issues and troubleshooting techniques.

1. Check the Power Supply

Begin by verifying that your refrigerator is receiving power. Ensure that it’s plugged into a working outlet and that the circuit breaker or fuse is not tripped. If the power supply is functioning correctly, proceed to the next step.

2. Inspect the Condenser Coils

The condenser coils located at the back or bottom of the refrigerator help dissipate heat. Dirty or clogged coils can hinder cooling performance. Use a vacuum cleaner or a soft brush to remove any dust or debris from the coils.

3. Clean the Evaporator Coils

The evaporator coils located inside the freezer compartment absorb heat from the food. They can become frosted or iced over, reducing cooling efficiency. Remove the freezer drawers and use a hair dryer on a low setting to melt any ice or frost.

4. Check the Thermostat

The thermostat regulates the temperature inside the refrigerator. A faulty thermostat can lead to incorrect cooling. Set the thermostat to a colder temperature and observe if the refrigerator starts cooling. If not, the thermostat may need to be replaced.

5. Inspect the Thermistor

The thermistor is a sensor that monitors the temperature inside the refrigerator. A malfunctioning thermistor can provide inaccurate temperature readings to the thermostat. Disconnect the thermistor and use a multimeter to test its resistance. Replace it if the resistance is not within the manufacturer’s specifications.

6. Check the Compressor

The compressor is the heart of the refrigeration system. It circulates the refrigerant throughout the system. If the compressor is not running, the refrigerator will not cool. Listen for the compressor running when you open the refrigerator door. If you hear no noise, the compressor may have failed and require replacement.

7. Inspect the Fan Motor

The fan motor circulates air inside the refrigerator and freezer compartments. A faulty fan motor can prevent proper air circulation, leading to uneven cooling. Check if the fan motor is running by opening the refrigerator door and listening for a whirring sound. If the fan motor is not running, it may need to be replaced.

8. Reset the Refrigerator

Sometimes, a simple reset can resolve cooling issues. Unplug the refrigerator from the power outlet for at least 5 minutes and then plug it back in. This will reset the refrigerator’s electronic components and may restore cooling functionality.

9. Call for Professional Help

If you have tried all the above steps and your LG refrigerator is still not cooling, it’s time to call for professional help. A qualified appliance repair technician can diagnose the exact cause of the issue and perform the necessary repairs.

Troubleshooting Tips

• If the refrigerator is cooling but not freezing, check the defrost timer or the defrost heater.
• If the refrigerator is making a loud noise, it could be due to a faulty compressor or fan motor.
• If the refrigerator is leaking water, check the drain hose for clogs or the ice maker for leaks.
