After using the refrigerator for a while, it may produce the annoying sound of filter clogging, causing discomfort to users and affecting daily activities. Many are uncertain about whether this issue impacts the repairability and functionality of the appliance. If you still have questions about this problem, read the article below to understand the causes and how to handle it.
1. Causes of Refrigerator Filter Clogging
Uneven Placement of the Refrigerator

After a period of operation, an unbalanced refrigerator, if one leg is uneven, can make the appliance vibrate, lightly touching the floor and resulting in the noise of filter clogging.
Offset Drain Tray
The drainage tray, positioned beneath the refrigerator by manufacturers, is designed to minimize vibration and noise during operation. In the case of misaligned drain tray, it contacts the condenser coil or cooling line, causing vibrations and the noise of filter clogging.
Loose Screws Fastening the Evaporator Coil

After a period of use, the screws in the refrigerator are prone to loosen. This leads to the compressor generating the noise of filter clogging.
Faulty Evaporator Fan
The fan blade motor of the refrigerator's evaporator fan lacking lubricating oil is also a cause of the noise of filter clogging.
Malfunctioning Refrigerator Block

If your refrigerator emits a filter clogging noise from the rear area, it's a clear sign that the refrigerator block is malfunctioning.
2. Guide on Resolving the Issue of Refrigerator Filter Clogging Noise
Refrigerator Imbalance
Carefully check if the refrigerator is in an imbalanced position. If so, carefully readjust the refrigerator's legs.

Many refrigerators come with easily adjustable spiral legs. Users can rotate the device clockwise or counterclockwise to adjust the height of the appliance.
Offset Drain Tray
Fixing the misalignment of the tray is extremely simple; users just need to move the tray back to its original position.
Refrigerator with Loose Screws

You can address this issue by tightening the loose screws. Regularly inspect and maintain the refrigerator to minimize the occurrence of loose screws.
Faulty Evaporator Fan
In case of this situation, first turn off the power and remove all food from the refrigerator. Use a screwdriver to access the air vent in the fridge compartment and gently pull the fridge out. Inside, locate the fan motor. Remove the motor, lubricate it with oil, reassemble the parts, and your refrigerator will be noise-free.
