Lg Fridge Not Working But Freezer Is

Introduction

Discovering that your LG fridge isn’t cooling while the freezer is working perfectly can be frustrating. This common issue means your refrigerated food is at risk of spoiling, leading to wasted groceries and potential health concerns. It’s important to address this problem quickly to prevent food waste and avoid the inconvenience of a malfunctioning refrigerator. This guide will help you understand the possible causes and walk you through simple troubleshooting steps before you consider calling a technician.

Common Causes of lg fridge not working but freezer is

Several factors can cause your LG fridge to stop cooling while the freezer continues to work normally:

Frozen Evaporator Coils: Ice buildup on the coils in the freezer can restrict airflow to the fridge.
Faulty Defrost System: A malfunctioning defrost heater, defrost timer, or defrost thermostat can prevent the coils from defrosting properly.
Damaged Door Seals: Worn-out door seals allow warm air to enter the fridge, affecting its cooling performance.
Blocked Vents: Vents that circulate cold air from the freezer to the fridge might be blocked by food items.
Faulty Thermistor: The thermistor is a sensor that monitors the fridge’s temperature. A faulty one can send incorrect temperature readings to the control board.
Damaged Damper Control: This controls the amount of cold air flowing from the freezer to the fridge. A broken damper can prevent proper cooling.
Condenser Coils Need Cleaning: Dirty condenser coils can’t efficiently dissipate heat, reducing overall cooling performance.
Faulty Start Relay/Capacitor: Less commonly, an issue with these components may affect the compressor’s cooling efficiency in the refrigerator compartment.

Symptoms Checklist

Use this checklist to help identify if the issue is really with the refrigerator section not cooling while the freezer works:

The freezer is cold and working as expected.
The refrigerator section is warm or at room temperature.
Food in the fridge is spoiling faster than usual.
You hear the freezer fan running, but not the fridge fan (if equipped with a separate fan).
Ice buildup is visible on the back wall of the freezer compartment.
The refrigerator door seals are visibly damaged or cracked.
The compressor (usually at the back of the unit) seems to be running constantly.

How to Fix lg fridge not working but freezer is Step-by-Step Guide

Follow these steps to troubleshoot your LG fridge:

Check the Temperature Settings: Make sure the temperature settings for both the fridge and freezer are correctly set. A too-high setting can cause the fridge to not cool adequately.
Clean the Condenser Coils: Locate the condenser coils (usually on the back or bottom of the fridge) and clean them with a vacuum cleaner and brush attachment. Dust buildup can restrict airflow.
Check the Door Seals: Inspect the door seals (gaskets) for damage or debris. Clean them with warm soapy water and ensure they create a tight seal when the door is closed. You can test the seal by closing the door on a dollar bill; it should be held firmly.
Clear Blocked Vents: Locate the vents that circulate cold air from the freezer to the fridge. Ensure they are not blocked by food items. Rearrange items to allow for proper airflow.
Defrost the Fridge Manually: If you suspect a frozen evaporator coil, manually defrost the fridge by unplugging it for 24-48 hours. Place towels inside to absorb any melting ice.
Check the Damper Control: Locate the damper control (usually in the upper part of the fridge). Make sure it’s opening and closing properly to allow cold air to flow.
Listen to the Fans: Open both the fridge and freezer doors. Listen for the sound of the evaporator fan in the freezer and, if your model has one, the condenser fan near the compressor. If a fan is not running, it could be the problem.
Check the Overload Protector/Relay: Located near the compressor, this small component can sometimes fail, preventing the compressor from starting correctly. If you’re comfortable, inspect for burns or damage (unplug first!).
Inspect the Defrost Timer/Control: If your model has a mechanical defrost timer, try manually advancing it to the defrost cycle. See if the defrost heater turns on (listen for a hissing sound). If not, the timer could be faulty.
Power Cycle the Fridge: Unplug the refrigerator from the outlet for 5-10 minutes, then plug it back in. This can sometimes reset the control board and resolve minor issues.

Fix the Issue Without Buying Parts

Before you consider purchasing replacement parts, try these cost-free solutions:

Reset: As mentioned, unplugging the fridge for a period can sometimes resolve the problem.
Cleaning: Thoroughly clean the interior of the fridge, including the vents and door seals.
Recalibration (If Applicable): Some LG models have a recalibration feature in the settings. Check your user manual to see if your model has this and how to use it.
Inspection Tips: Regularly inspect the condenser coils and door seals to prevent future problems.
Maintenance Basics: Practice good refrigerator maintenance, such as avoiding overfilling the fridge and keeping the door closed as much as possible.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and the fridge is still not cooling, a replacement part may be needed. Common parts that fail include the defrost heater ($50-$100), the defrost timer/control ($40-$80), the thermistor ($20-$40), or the damper control ($30-$60). In very rare cases, the compressor may be the issue. Replacing the compressor is expensive ($300-$700 including labor) and often not worth it on an older refrigerator. Before replacing any parts, consider getting a professional diagnosis to ensure you’re addressing the root cause of the problem.

Safety Warning

Always unplug the refrigerator from the power outlet before performing any repairs.
Be careful when working with electrical components. If you’re not comfortable, seek professional help.
Avoid working on the fridge with wet hands or while standing on a wet floor.
Be cautious when handling refrigerant lines, as they can cause frostbite.

Tools You May Need

Screwdrivers (Phillips and flathead)
Vacuum cleaner with brush attachment
Warm water and mild soap
Towel
Multimeter (for testing electrical components – optional)

FAQ

Here are some frequently asked questions about this issue:

Q: How long can I leave my fridge unplugged to defrost it?
A: It’s best to leave it unplugged for 24-48 hours to ensure all the ice melts.
Q: How do I know if my door seals are bad?
A: Visually inspect for cracks or tears. You can also test the seal with a dollar bill.
Q: Where are the condenser coils located on my fridge?
A: They are typically located on the back of the fridge or at the bottom, behind a panel. Consult your owner’s manual for the exact location.
Q: My fridge is still not cooling after defrosting. What should I do?
A: Try cleaning the condenser coils and checking the damper control. If the problem persists, you may need to call a technician.
Q: How do I check the thermistor?
A: A multimeter is needed for this. Refer to your fridges service manual for the correct resistance values at specific temperatures, then unplug the appliance before using the meter.

Conclusion

Troubleshooting your LG fridge when the freezer is working, but the fridge isn’t can seem daunting, but by following these steps, you can often identify and resolve the issue yourself. Start with the simpler solutions like cleaning the coils and checking the door seals. Don’t be afraid to try a manual defrost. If you’re still experiencing problems after trying these steps, it might be time to consult a qualified appliance repair technician. Attempting these DIY fixes first can save you money and time before calling for professional help.
