Lg Fridge Making Clicking Noise

Introduction

Is your LG refrigerator making a clicking noise? That repetitive “click… click… click…” can be unsettling, and it often indicates that something isn’t quite right inside your appliance. While a clicking sound might seem minor, ignoring it can sometimes lead to more significant issues and potentially shorten the lifespan of your fridge. This guide is designed to help you, the homeowner, diagnose and potentially fix the problem yourself, saving you money and the inconvenience of a service call. We’ll walk through common causes, symptoms, and troubleshooting steps in plain English, so you can get your fridge back to its quiet, efficient operation. Addressing this issue promptly can prevent food spoilage and ensure your fridge runs smoothly.

Common Causes of LG Fridge Making Clicking Noise

Here are some of the most frequent culprits behind a clicking noise in your LG fridge:

Start Relay: This small component helps start the compressor. A failing start relay is a common cause of clicking, as it attempts to engage the compressor repeatedly.
Overload Protector: This device protects the compressor from overheating. If it’s tripping due to a problem, it will click as it repeatedly turns on and off.
Compressor Issues: The compressor itself might be struggling to start. This can be due to age, wear, or internal damage.
Defrost Timer: In older models, a defrost timer switches the fridge into defrost mode. The timer can make a clicking noise as it cycles.
Ice Maker: If your fridge has an ice maker, the clicking could be related to its cycling, water valve operation, or ice release mechanism.
Water Inlet Valve: If you have a water dispenser or ice maker, a faulty water inlet valve might be clicking as it tries to regulate water flow.
Evaporator Fan Motor: The fan motor might be struggling to start or have an obstruction, causing a clicking sound.
Temperature Control: Issues with the temperature control thermostat can cause the compressor to cycle on and off frequently, resulting in clicking.
Expansion/Contraction: Sometimes, the clicking can simply be due to the plastic and metal components of the fridge expanding and contracting as the temperature changes, particularly in newer refrigerators.

Symptoms Checklist

Use this checklist to help pinpoint the cause of the clicking:

Clicking sound comes from the back of the fridge (compressor area).
Clicking sound is intermittent, not constant.
Fridge isn’t cooling properly.
Ice maker isn’t producing ice.
Water dispenser isn’t working.
Clicking sound occurs every few minutes.
Clicking accompanied by other noises like humming or buzzing.
Clicking stops when the fridge is unplugged.

How to Fix LG Fridge Making Clicking Noise Step-by-Step Guide

Important: Always unplug your fridge before attempting any repairs!

Listen Carefully: First, pinpoint the location of the clicking. Is it coming from the back (compressor), inside the fridge, or near the ice maker?
Check the Back Panel: Carefully remove the cardboard or metal panel on the back of the fridge to access the compressor area.
Locate the Compressor: The compressor is a black, tank-like component. Identify the start relay and overload protector attached to it (usually a small box or cylinder).
Inspect the Start Relay and Overload Protector: Look for any signs of burning, melting, or bulging on these components. If you see damage, proceed to the next step carefully.
Check the Defrost Timer (Older Models): If your fridge has a dial-type temperature control, it might have a defrost timer. Listen to see if the clicking comes from this timer.
Examine the Ice Maker: If your fridge has an ice maker, observe it during its cycle. Listen for any clicking sounds related to the water valve or ice ejection.
Inspect the Water Inlet Valve: Locate the water inlet valve (usually near the back of the fridge where the water line connects). Check for leaks or any signs of damage.
Check the Evaporator Fan (Inside Fridge): Open the freezer and listen for the evaporator fan. Ensure it’s not obstructed by ice or debris and that the motor isn’t clicking as it tries to start. You may need to remove a panel to access it.
Clean the Condenser Coils: Located on the back or bottom of the fridge, dirty condenser coils can cause the compressor to work harder and overheat. Vacuum them thoroughly.
Check for Leveling Issues: Ensure your fridge is level. An unlevel fridge can cause components to vibrate and click. Use a level to check.
Restart the Fridge: After inspecting everything, plug the fridge back in and observe. Does the clicking continue?
Monitor Temperature: Use a fridge thermometer to ensure the temperature is within the correct range (37-40F or 3-4C). If the fridge isn’t cooling properly, it could indicate a compressor issue.

Fix the Issue Without Buying Parts

Before considering replacing any parts, try these free methods:

Reset: Unplug the fridge for at least 30 minutes. This can sometimes reset the compressor and other components.
Cleaning: As mentioned, clean the condenser coils. Also, clean around the fridge, ensuring proper ventilation.
Recalibration (If Applicable): Some LG fridges have a self-diagnostic or recalibration feature in the settings. Check your user manual for instructions.
Inspection Tips: Thoroughly inspect the back of the fridge for anything loose or vibrating. Secure any loose components.
Maintenance Basics: Regularly clean the interior of your fridge and freezer to ensure proper airflow.

When Replacement Might Be Necessary

If the clicking persists after trying the above steps, a failing component might be the cause. Common parts that fail and could require replacement include:

Start Relay/Overload Protector: $20-$50 USD.
Defrost Timer: $30-$70 USD.
Water Inlet Valve: $40-$80 USD.
Evaporator Fan Motor: $50-$100 USD.
Compressor: Replacing the compressor is a major repair, costing $300-$800+ USD. If the compressor is failing, consider whether it’s more cost-effective to replace the entire fridge.

Always get a quote from a certified technician before replacing a compressor.

Safety Warning

Always unplug the refrigerator before working on it.
Avoid touching any electrical components with wet hands.
Be careful when handling tools to avoid injury.
If you are uncomfortable performing any of these steps, consult a qualified appliance repair technician.
Make sure the floor is dry before plugging the appliance back in.

Pliers

FAQ

Q: Why is my fridge clicking even when it’s cooling properly? A: It could still be a defrost timer issue, or related to the ice maker cycling.
Q: How do I know if the compressor is the problem? A: If the fridge isn’t cooling, and you hear clicking from the compressor area, it’s a strong indication.
Q: Can I replace the start relay myself? A: Yes, it’s a relatively simple repair, but ensure you purchase the correct replacement for your LG fridge model.
Q: My fridge is new; is this normal? A: Some clicking is normal due to expansion/contraction, but persistent, loud clicking isn’t. Contact LG or the retailer.
Q: How often should I clean the condenser coils? A: At least twice a year, or more frequently if you have pets.
