If your LG refrigerator has started making strange or loud noises, it can be concerning — especially if the sound is new or getting worse. While some refrigerator noises are normal, others can signal a problem that needs attention.
Below are the most common reasons an LG refrigerator may be making noise, what those sounds usually mean, and when it’s time to contact a local appliance repair professional.
Common Noises an LG Refrigerator May Make
Not all refrigerator noises indicate a problem. However, changes in sound are often worth checking.
You may notice:
-
Buzzing or humming
-
Clicking or tapping
-
Rattling or vibrating
-
Grinding or squealing
-
Popping or cracking sounds
Understanding where the noise is coming from helps narrow down the cause.
Normal Operating Sounds
Some sounds are part of normal refrigerator operation, especially in newer LG models.
These include:
-
A low humming sound when the compressor runs
-
Clicking sounds as the thermostat turns on and off
-
Popping or cracking noises caused by temperature changes
If the noise is brief and not excessively loud, it may not be a cause for concern.
Dirty or Faulty Condenser Fan
The condenser fan helps cool the refrigerator by moving air across the condenser coils. If dust, debris, or wear affects the fan, it can cause buzzing, rattling, or grinding noises.
What you can check:
-
Unplug the refrigerator
-
Inspect the area near the back or bottom
-
Look for visible debris or loose components
If the fan blades are damaged or the motor is failing, professional repair is recommended.
Evaporator Fan Motor Issues
The evaporator fan circulates cold air inside the refrigerator and freezer. When this fan starts to fail, it may produce squealing, chirping, or loud humming sounds.
Common signs:
-
Noise coming from inside the freezer
-
The sound changes when the door opens or closes
-
Uneven cooling inside the refrigerator
Evaporator fan motor issues usually require replacement by a technician.
Compressor Problems
A loud or persistent buzzing, knocking, or rattling noise coming from the back of the refrigerator may be related to the compressor.
While compressors normally make a low hum, louder or unusual sounds can indicate wear or failure. Compressor issues should always be inspected by a professional due to complexity and cost.
Loose Parts or Refrigerator Placement
Sometimes the noise isn’t an internal problem at all. Loose panels, items on top of the refrigerator, or uneven placement can cause rattling or vibrating sounds.
What you can try:
-
Make sure the refrigerator is level
-
Check for loose screws or panels
-
Remove items resting on top of the unit
When to Call a Local Appliance Repair Technician
If the noise is loud, persistent, or getting worse, it’s best not to ignore it. Continuing to run a refrigerator with a failing component can lead to more serious damage.
You should contact a professional if:
-
The noise is constant or very loud
-
Cooling performance is affected
-
You hear grinding or squealing sounds
-
The refrigerator stops cooling properly
