An LG refrigerator making clicking noise can signal a minor issue or the start of a major failure. Addressing the sound early helps protect your appliance, food, and energy bill.
This guide explains what causes the noise, simple steps to resolve it, and when it’s time to contact our LG refrigerator repair experts. If you’re asking, “Why is my LG fridge clicking?”, here’s what you need to know.
Why an LG Refrigerator Making Clicking Noise Shouldn’t Be Ignored
A persistent clicking sound from an LG refrigerator usually means a component isn’t functioning correctly. These appliances are designed to operate quietly, so clicking noises often signal a problem that needs attention.
Common Causes:
- Dirty condenser coils: Dust build-up causes overheating, which may result in clicking.
- Faulty compressor start relay: This part helps start the compressor and may click repeatedly if it’s malfunctioning.
- Blocked evaporator fan: Ice or debris can hit the fan blades and cause a clicking sound.
- Failing compressor: A compressor trying to start and failing can make repeated clicking noises.
If you notice an LG fridge clicking sound that occurs frequently or continuously, it’s best to start with basic checks. Catching and resolving the issue early can save time and money.
Step-by-Step: Stop Your LG Refrigerator Making Clicking Noise
Safety First: Before starting, turn off the refrigerator’s power from the breaker panel. This ensures safe inspection and prevents further damage.
Tools You May Need:
- Vacuum with hose attachment
- Phillips screwdriver
- Clean cloth
- Level
- Flashlight
Step 1: Clean the Condenser Coils
The easiest and most common solution for an LG refrigerator making clicking noise is cleaning the condenser coils.
Dirty coils lead to overheating and cause the compressor to cycle on and off.
- Locate the coils (usually behind or underneath the unit)
- Use the vacuum to remove visible dust and debris
- Wipe with a clean, dry cloth
- Repeat every 6 months
This simple maintenance task can restore efficiency and eliminate the clicking noise. If the noise continues, move to the next step.
Step 2: Level the Refrigerator to Eliminate Vibration Noise
An unlevel refrigerator can cause internal components to vibrate or shift, sometimes resulting in a clicking or knocking noise. This step is easy and often overlooked.
- Use a level to check the fridge’s balance front-to-back and side-to-side
- Adjust the front leveling legs with a wrench or pliers
- Ensure both front legs are firmly touching the floor
- Tilt the fridge slightly backward so the doors close automatically
- Recheck the balance after adjustments
Leveling the unit stabilizes internal parts and reduces strain on the compressor and fan. If the clicking noise remains, continue to the next step.
Step 3: Remove Ice Buildup from the Evaporator Fan
If the clicking comes from inside the freezer or fridge, ice could be hitting the evaporator fan blades. This is a common reason for an LG refrigerator clicking noise inside the unit.
- Open the freezer and listen for the noise source
- Remove shelving and interior panel to access the fan
- Check for ice, frost, or debris around the blades
- Let any ice melt naturally or gently wipe away
- Reassemble and restore power
Clearing the blockage allows the fan to spin freely, often silencing internal clicking sounds.
Step 4: Inspect the Drain Pan and Water Line
Sometimes the clicking noise in an LG refrigerator is due to components shifting or tapping when water flows or drains, especially during defrost cycles. Other times, the cause is entirely external.
- Slide the fridge forward carefully to access the back
- Use a flashlight to inspect the drain pan near the bottom
- Ensure the pan is not loose or vibrating against any surfaces
- Check the water line to make sure it’s not bumping into the back panel or coils
- Adjust any parts that may be tapping or rattling
These small adjustments can reduce or eliminate clicking caused by vibrations or normal operation noise.
Step 5: Check the Ice Maker
If the ice maker is turned on but not connected to a water supply, it may make repeated clicking sounds during unsuccessful fill attempts.
- Locate the ice maker and listen for rhythmic clicking
- Check if the water supply line is connected and the valve is open
- If not using the ice maker, turn it off using the switch or control panel
- Monitor for clicking to see if it stops after the ice maker is disabled
Disabling an unused ice maker can stop unnecessary cycling and resolve the clicking noise at its source.
Once all troubleshooting steps are complete, return to your breaker panel and restore power to the refrigerator to resume normal operation.
When to Schedule Professional LG Refrigerator Repair
If your LG refrigerator continues making a clicking noise after trying these steps, it’s time to schedule professional service.
Prompt service prevents further damage and restores normal operation quickly.
FAQs About LG Refrigerator Making Clicking Noise
Why is my LG refrigerator making clicking noise and then stops cooling?
This typically means the start relay is faulty or the compressor is struggling to start. A replacement relay may solve the issue.
Can I ignore a small clicking noise from my LG fridge?
You shouldn’t. Even small, repetitive clicks may indicate a developing fault. Early attention helps avoid costly repairs.
How can I tell if the compressor is the problem?
If you hear a hum followed by a click, or the fridge runs warm despite being powered, the compressor may be failing.
Could a power surge cause my LG refrigerator to start clicking?
Yes. A power surge can damage sensitive components like the start relay or control board, leading to repeated clicking sounds. If the noise began after a recent outage or electrical event, professional diagnostics may be needed.
Helpful Tip for Reducing LG Refrigerator Noise
Once a month, gently pull your refrigerator forward and vacuum behind and underneath it to remove dust and debris. Keeping this area clean helps maintain proper airflow, reduces compressor stress, and supports quieter operation over time.
If your LG refrigerator making clicking noise problem persists and you’re unsure how to proceed, contact Appliance Repair Specialists for expert service.
