Refrigerator Not Cooling Hear Clicking Sound

Introduction

Is your refrigerator not cooling properly and making a distinct clicking sound? This is a common problem that many homeowners face. When your fridge isn’t cooling, food spoilage is a real concern, potentially leading to wasted groceries and even health risks. The clicking sound often indicates a problem with the compressor or a related component. It’s crucial to address this issue quickly to prevent further damage and keep your food fresh and safe. Don’t panic! This guide will walk you through troubleshooting steps before you need to call a repair technician.

Common Causes of Refrigerator Not Cooling, Hearing Clicking Sound

Here are several common reasons why your refrigerator might not be cooling and is making a clicking sound:. For more related activities, check out our Whirlpool Gold Refrigerator Freezer Leaking Water.

• Dirty Condenser Coils: Dust and debris on the coils prevent proper heat dissipation.
• Faulty Start Relay: This small device helps start the compressor. When it fails, it can cause clicking.
• Overload Protector Tripped: The overload protector shuts down the compressor if it overheats.
• Failed Compressor: The compressor is the heart of the cooling system. If it’s failing, it can cause a clicking sound.
• Defrost System Issues: Problems with the defrost heater, defrost timer, or defrost thermostat can lead to ice buildup and cooling problems.
• Frozen Evaporator Coils: Ice buildup on the evaporator coils restricts airflow and cooling.
• Blocked Condenser Fan: If the condenser fan isnt working, the fridge can’t properly cool the refrigerant.
• Door Seal Problems: A worn or damaged door seal allows warm air to enter, making the refrigerator work harder.
• Temperature Control Problems: A malfunctioning thermostat can cause the refrigerator to not cool properly.

Symptoms Checklist

Check if you notice any of these symptoms:

• Refrigerator is warm, but the freezer may be working.
• Refrigerator is not cooling, and the freezer is also warm.
• You hear a distinct clicking sound coming from the back or bottom of the refrigerator.
• The compressor starts and then immediately shuts off.
• The refrigerator is running constantly but not cooling effectively.
• Ice buildup on the back wall of the refrigerator.
• The condenser fan is not running.

How to Fix Refrigerator Not Cooling, Hearing Clicking Sound Step-by-Step Guide

1. Unplug the Refrigerator: For safety, disconnect the refrigerator from the power outlet before starting any troubleshooting.
2. Clean the Condenser Coils: Locate the coils (usually at the back or bottom of the fridge) and use a vacuum cleaner or brush to remove dust and debris.
3. Check the Condenser Fan: Make sure the fan is free of obstructions and spins freely. If not, clear any debris. If it doesn’t spin, it may need professional attention.
4. Inspect the Door Seals: Check the door seals for damage or gaps. Clean the seals with warm, soapy water. A simple dollar bill test can identify leaks: close the door on the bill, and see how easily it slides out.
5. Listen to the Compressor: Locate the compressor (usually at the back of the fridge, near the bottom). Listen for the clicking sound. Note if it cycles on and off quickly.
6. Check the Start Relay and Overload Protector: These are typically located on the side of the compressor. If comfortable and after unplugging the refrigerator, you can visually inspect them for signs of damage (bulging, burning). Do NOT attempt to test them if you are unfamiliar with electrical components.
7. Defrost the Refrigerator (Manual Defrost Models): If your refrigerator is a manual defrost model, completely defrost it to eliminate ice buildup.
8. Check the Evaporator Coils: If accessible, inspect the evaporator coils (usually behind a panel inside the freezer). If they are covered in ice, the defrost system may be faulty.
9. Adjust the Temperature Settings: Ensure the temperature settings are correct. Sometimes, a simple adjustment can solve the problem.
10. Check the Power Outlet: Make sure the refrigerator is plugged into a working outlet. Test the outlet with another appliance.
11. Reset the Refrigerator: After checking everything, unplug the refrigerator for 30 minutes, then plug it back in. This can sometimes reset the system.

Fix the Issue Without Buying Parts

Before considering replacements, try these free and simple methods:

• Deep Cleaning: Regularly clean the interior and exterior of your refrigerator to prevent buildup of dust and grime.
• Proper Airflow: Don’t overfill your refrigerator. Allow adequate space for air to circulate.
• Correct Temperature Settings: Ensure your refrigerator and freezer are set to the correct temperatures (typically 37F (3C) for the refrigerator and 0F (-18C) for the freezer).
• Door Seal Maintenance: Clean your door seals regularly and replace them if they are damaged or worn.

When Replacement Might Be Necessary

If, after troubleshooting, the refrigerator still isn’t cooling and the clicking sound persists, a failing compressor is likely. This often requires professional repair or replacement. Replacing a compressor can cost between $300 and $700 (USD), including labor. Other parts that commonly fail and might warrant replacement include the start relay ($20-$50), overload protector ($15-$40), or defrost timer ($30-$60).

Safety Warning

• Always unplug the refrigerator before performing any maintenance or repairs.
• Avoid working on electrical components if you are not comfortable or experienced.
• Be careful when handling sharp tools or cleaning chemicals.
• Keep the area around the refrigerator dry to prevent electrical shock.

Tools You May Need

• Screwdrivers (Phillips and flathead)
• Vacuum cleaner with hose attachment
• Soft brush
• Warm, soapy water
• Clean cloth
• Multimeter (optional, for testing electrical components use with caution and proper knowledge)

FAQ

Q: Why is my refrigerator clicking but not cooling?A: The clicking sound often indicates a problem with the compressor, start relay, or overload protector. These components may be failing, preventing the compressor from starting or running properly.

Q: How can I tell if my refrigerator compressor is bad?A: Signs of a bad compressor include a clicking sound, the compressor starting and then immediately shutting off, or the refrigerator not cooling despite the compressor running constantly.

Q: Can I fix a refrigerator compressor myself?A: Replacing a compressor is a complex and potentially dangerous task that usually requires a trained technician. It involves working with refrigerant, which is a controlled substance.

Q: How often should I clean my refrigerator coils?A: Clean your refrigerator coils at least twice a year, or more often if you have pets or live in a dusty environment.

Conclusion

Troubleshooting a refrigerator that isn’t cooling and is making a clicking sound can seem daunting, but by following these steps, you can often identify and resolve the issue yourself. Remember to prioritize safety and take your time. If you’ve tried these steps and your refrigerator still isn’t working, it may be time to call a qualified appliance repair technician for further assistance.
