Lg Side By Side Refrigerator Freezer Not Cooling

Introduction

Discovering your LG side-by-side refrigerator freezer isn’t cooling properly can be a major headache. Food spoils quickly, leading to waste and unexpected expenses. This issue often crops up unexpectedly, whether after a power outage, a hot summer day, or simply out of the blue. Addressing this problem quickly is crucial to prevent food from going bad and save you money on groceries.

Common Causes of lg side by side refrigerator freezer not cooling

Here are some common culprits behind a refrigerator freezer that’s not cooling:

• Dirty Condenser Coils: Dust and debris accumulate on these coils, hindering heat release.
• Frost Buildup: Excessive frost can insulate the cooling elements, preventing proper cooling.
• Blocked Vents: Obstructions can restrict airflow between the freezer and refrigerator.
• Faulty Door Seals: Worn seals allow warm air to enter, impacting cooling efficiency.
• Condenser Fan Issues: A malfunctioning fan prevents proper heat dissipation from the condenser coils.
• Evaporator Fan Problems: If the evaporator fan isn’t working, cold air won’t circulate effectively.
• Defrost System Malfunction: Problems with the defrost timer, heater, or thermostat can lead to excessive frost.
• Compressor Problems: The compressor is the heart of the cooling system; if it fails, cooling stops.
• Control Board Issues: A faulty control board can disrupt the cooling cycle.

Symptoms Checklist

Look for these indicators to confirm the problem:

• Refrigerator temperature noticeably warmer than usual.
• Freezer temperature above freezing (32F or 0C).
• Food spoiling faster than normal.
• Excessive frost buildup in the freezer.
• Unusual noises coming from the refrigerator.
• Condensation or moisture inside the refrigerator.

How to Fix lg side by side refrigerator freezer not cooling Step-by-Step Guide

1. Check the Power: Ensure the refrigerator is plugged in securely and the outlet is working. Test the outlet with another appliance.
2. Inspect the Temperature Settings: Make sure the temperature settings haven’t been accidentally changed. Set the refrigerator to around 37F (3C) and the freezer to 0F (-18C).
3. Clean the Condenser Coils: Locate the condenser coils (usually at the back or bottom of the refrigerator) and clean them with a vacuum cleaner and a brush. Unplug the refrigerator before cleaning.
4. Defrost the Freezer Manually: If there’s excessive frost buildup, unplug the refrigerator and let the freezer defrost completely (this may take several hours). Place towels to absorb water.
5. Check the Vents: Ensure the vents inside the refrigerator and freezer are not blocked by food items. Rearrange items to allow proper airflow.
6. Inspect the Door Seals: Check the door seals for damage or gaps. Clean the seals with warm soapy water. A simple test is to place a dollar bill between the door and the refrigerator frame and see if you can easily pull it out when the door is closed.
7. Listen to the Fans: Listen for the condenser and evaporator fans. If you don’t hear them running, they might be faulty. (Proceed to step 8 to access and inspect these)
8. Access and Inspect Fans (If Comfortable): Unplug the refrigerator first! Accessing the fans typically involves removing panels inside the freezer or at the back of the unit. Visually inspect the fans for obstructions (ice buildup, debris). Try manually spinning the fan blades to see if they move freely.
9. Check the Overload Protector:The overload protector is a safety device that protects the compressor from overheating. It’s typically located near the compressor. If it’s tripped, reset the appliance.
10. Check the Start Relay:The start relay helps the compressor start the cooling process by delivering additional current to the compressor. It is also located near the compressor. If it goes wrong, it can prevent the compressor from starting.
11. Check the Defrost Drain: A clogged defrost drain can cause water to accumulate and freeze, leading to cooling issues. Locate the drain (usually at the back of the freezer) and clear any blockages with warm water or a pipe cleaner.
12. Reset the Refrigerator: Unplug the refrigerator for 10-15 minutes, then plug it back in. This can sometimes reset the control board and resolve minor issues.

Fix the Issue Without Buying Parts

Often, the issue can be resolved without needing to replace any parts:

• Regular Cleaning: Clean the condenser coils every 6 months to prevent dust buildup.
• Proper Food Storage: Avoid overcrowding the refrigerator and freezer, and ensure proper airflow.
• Seal Maintenance: Regularly clean the door seals to maintain a tight seal.
• Monitor Temperature: Keep an eye on the temperature settings and adjust them as needed.

When Replacement Might Be Necessary

If the problem persists after trying the above steps, the compressor or control board might be faulty. Replacing these components can be costly. A compressor replacement can range from $300-$700, while a control board replacement can cost $150-$400. Consider the age and condition of your refrigerator before investing in a costly repair. Common parts to consider replacing are the start relay, overload protector, or the control board. For more related activities, check out our Lg Refrigerator Water And Ice Dispenser Not Working.

Safety Warning

• Always unplug the refrigerator before performing any maintenance or repairs.
• Avoid working on electrical components if you’re not comfortable or experienced.
• Keep the floor dry to prevent slips and falls.
• Be careful when handling sharp tools or components.

Tools You May Need

• Screwdriver (Phillips and flathead)
• Vacuum cleaner with brush attachment
• Warm soapy water and a cloth
• Pipe cleaner or small brush
• Multimeter (optional, for testing electrical components)

FAQ

Q: Why is my refrigerator warm but my freezer is cold?
A: This could be due to a blocked vent between the freezer and refrigerator, a faulty damper, or a problem with the evaporator fan.

Q: How often should I clean the condenser coils?
A: Aim to clean them every 6 months to maintain optimal cooling performance.

Q: What if my refrigerator is making a loud buzzing noise?
A: This could indicate a problem with the compressor or one of the fans. Inspect the fans first, and if the noise persists, the compressor might need professional attention.

Q: How do I know if my door seals are bad?
A: A simple test is to close the door on a dollar bill. If you can easily pull it out, the seal is likely worn and needs replacement.

Conclusion

Troubleshooting an LG side-by-side refrigerator freezer that isn’t cooling can seem daunting, but by following these steps, you can often identify and resolve the issue yourself. Before calling a technician, try these simple fixes. You might be surprised at how much you can accomplish. If problems persist, consult a qualified appliance repair professional.
