Fridge Making Clicking Sound And Not Cooling

Introduction

Is your fridge clicking annoyingly but failing to keep your food cold? This is a common problem that many homeowners face. The clicking sound often indicates a problem with the refrigerator’s components trying (and failing) to start up. A fridge that isn’t cooling is a serious issue, as it can quickly lead to food spoilage and potential health risks. Addressing this problem quickly is crucial to prevent food waste and avoid costly repairs down the line.

Common Causes of Fridge Making Clicking Sound and Not Cooling

Here are several reasons why your fridge might be making a clicking sound and not cooling properly:

Failed Start Relay: The start relay helps kick-start the compressor. If it’s faulty, it may click repeatedly as it tries to engage the compressor.
Faulty Compressor: The compressor is the heart of the cooling system. A failing compressor might click but be unable to start.
Overload Protector Tripping: The overload protector is designed to shut down the compressor if it overheats. A faulty protector can repeatedly trip and click.
Dirty Condenser Coils: Dust and debris on the condenser coils can prevent proper heat dissipation, causing the compressor to work harder and potentially fail.
Frozen Evaporator Coils: If the evaporator coils freeze over, airflow is blocked, hindering cooling and potentially causing clicking sounds.
Defrost System Malfunction: A malfunctioning defrost system can lead to ice buildup on the evaporator coils.
Damaged Fan Motors: Both the condenser fan and evaporator fan are essential for airflow. If either fails, it can lead to overheating and clicking.
Power Supply Issues: Insufficient or fluctuating power can prevent the compressor from starting properly, resulting in clicking.
Thermostat Problems: A malfunctioning thermostat might not accurately sense the temperature, leading to incorrect cooling cycles and potential compressor issues.

Symptoms Checklist

Use this checklist to pinpoint the exact problem:

Clicking sound coming from the back or bottom of the fridge.
Fridge interior is warm, not cold.
Freezer is also not freezing properly.
The compressor is not running.
Condenser fan not running.
Evaporator fan not running.
Ice buildup on the back wall of the freezer.
Food spoils quickly.

How to Fix Fridge Making Clicking Sound and Not Cooling Step-by-Step Guide

Follow these steps to troubleshoot your fridge:

Unplug the Fridge: For safety, always unplug the fridge before starting any troubleshooting.
Clean the Condenser Coils: Locate the coils (usually on the back or bottom). Use a vacuum cleaner with a brush attachment to remove dust and debris.
Check the Condenser Fan: Make sure the condenser fan spins freely. If it’s blocked or not turning, remove any obstructions. If it still doesn’t spin, the motor might be faulty.
Listen to the Compressor: Carefully listen near the compressor (a black, egg-shaped component). If you hear a clicking sound but the compressor doesn’t start, the start relay or compressor itself might be failing.
Inspect the Evaporator Coils: Locate the evaporator coils (usually behind a panel inside the freezer). Check for excessive ice buildup.
Test the Defrost System: If the evaporator coils are iced over, the defrost system might be malfunctioning. Check the defrost timer, defrost heater, and defrost thermostat.
Check the Door Seals: Ensure the door seals are clean and create a tight seal. Damaged seals let warm air in, forcing the fridge to work harder.
Adjust the Thermostat: Make sure the thermostat is set to the correct temperature. A setting that’s too warm can prevent the fridge from cooling properly.
Check the Overload Protector: The overload protector is a small device attached to the compressor. If you can access it (after unplugging the fridge), check if it shows signs of damage.
Check the Start Relay: The start relay is also attached to the compressor. If you can access it (after unplugging the fridge), check for burns or cracks.
Reset the Fridge: Unplug the fridge for 30 minutes, then plug it back in. This can sometimes reset the system and resolve minor issues.
Check the Power Outlet: Ensure the power outlet is working by plugging in another appliance.

Fix the Issue Without Buying Parts

Sometimes, you can fix the problem without replacing any parts:

Resetting: As mentioned above, unplugging the fridge for 30 minutes can sometimes reset the system.
Cleaning: Regularly cleaning the condenser coils is crucial for efficient cooling.
Door Seal Inspection: Regularly check the door seals for damage. Clean them with mild soap and water.
Proper Loading: Avoid overcrowding the fridge, as this can restrict airflow.
Leveling: Ensure the fridge is level. An unlevel fridge can cause door sealing issues.

When Replacement Might Be Necessary

If the clicking sound persists and the fridge still isn’t cooling after trying the above steps, a replacement might be needed. Common failing parts include the compressor (estimated cost: $200-$500), the start relay ($20-$50), or the defrost heater ($30-$70). Sometimes, the cost of repair can be almost as much as a new refrigerator. Consider a replacement if your fridge is old and inefficient or if the repair cost is substantial.

Safety Warning

Always unplug the refrigerator before performing any repairs.
Avoid working on electrical components with wet hands or on a wet floor.
Be careful when handling sharp tools.
If you are not comfortable working with electrical appliances, consult a qualified technician.

FAQ

Here are some frequently asked questions:

Q: Why is my fridge clicking but not cooling?A: The clicking sound is often related to the compressor trying (and failing) to start. This could be due to a faulty start relay, compressor, or overload protector.
Q: How can I tell if the compressor is bad?A: If you hear a clicking sound but the compressor doesn’t start, and you’ve already checked the start relay and overload protector, the compressor itself is likely the problem.
Q: Can I fix a fridge that’s not cooling myself?A: Yes, you can try troubleshooting steps like cleaning the coils, checking the fan, and resetting the fridge. However, more complex repairs may require a technician.
Q: How often should I clean the condenser coils?A: It’s recommended to clean the condenser coils at least twice a year for optimal performance.

Conclusion

Don’t panic if your fridge is making a clicking sound and not cooling. By following these troubleshooting steps, you can often identify and fix the problem yourself, saving you money on costly repairs. Remember to prioritize safety and, if you’re unsure about any step, consult a qualified technician. Start with the simple solutions first. You might be surprised how often a good cleaning or reset can solve the issue!
