If you have an LG fridge, you may notice that it makes some noise during normal operation. This is usually nothing to worry about, as most fridges make some noise due to the flow of refrigerant, the operation of the compressor and fan, and the expansion and contraction of plastic parts. However, if your LG fridge is making loud or unusual noise, such as knocking, hissing, gurgling, or rattling, it may indicate a problem that needs your attention. In this post, we’ll explain why your LG fridge is making noise and how to fix it.
Your LG fridge is making noise because of various reasons, such as insufficient clearance, obstructed or defective fan, dirty condenser coils, jammed ice maker, water hammering, and a nonworking ice maker. To fix the noise issue, you need to check the clearance around the fridge, clean the fan and coils, unjam the ice maker, install a water hammer arrestor, and replace the ice maker if needed.
How To Identify The Source Of The Noise On Your LG Fridge
Before you can fix the noise issue on your LG fridge, you need to identify the source and type of the noise. Different noises may have different causes and solutions. Here are some common noises that your LG fridge may make and how to locate them:
- Knocking or pounding noise: This may indicate a problem with the compressor or the water valve. The compressor is located at the back or bottom of the fridge and is responsible for pumping refrigerant throughout the system. The water valve is located at the back of the fridge and is responsible for supplying water to the dispenser and ice maker. To check if the noise is coming from the compressor or the water valve, listen carefully at the back or bottom of the fridge.
- Hissing or gurgling noise: This may indicate a normal flow of refrigerant or a leak in the system. The refrigerant is a liquid that circulates through the coils and evaporates to cool down the fridge. To check if the noise is normal or not, listen carefully at the back or bottom of the fridge and see if it stops after a few minutes or continues for a long time.
- Cracking, clicking, or water dripping noise: This may indicate a normal expansion and contraction of plastic parts or a defrost cycle. The plastic parts such as shelves and drawers may expand or contract when the temperature inside the fridge changes. The defrost cycle is a process that melts any frost that accumulates on the evaporator coils inside the freezer. To check if the noise is normal or not, listen carefully inside the fridge and see if it occurs randomly or periodically.
- Vibrating noise: This may indicate an improper leveling or stabilization of the fridge. The fridge may vibrate if it is not level or if it is touching any other objects such as walls or cabinets. To check if the noise is caused by vibration, move any objects away from the fridge and adjust the leveling feet at the bottom of the fridge.
- Air leaking noise: This may indicate a normal pressure difference inside the fridge when you open and close the door fast. The warm air from the outside meets the cold air inside the fridge, creating a difference in the pressure inside the fridge. Air inside the fridge escapes through a vent at the back of the fridge, creating an air escaping sound. To check if the noise is normal or not, listen carefully at the back of the fridge and see if it occurs only when you open and close the door fast.
How To Fix The Noise Issue On Your LG Fridge
Once you have identified the source and type of the noise on your LG fridge, you can try to fix it by following these steps:
- For a knocking or pounding noise from the compressor or water valve, you may need to call a professional for repair, as specialized tools and knowledge are needed to fix the issue.
- For a hissing or gurgling noise from a refrigerant leak, you may need to call a professional for repair, as refrigerant is a hazardous substance that requires proper handling and disposal.
- For a cracking, clicking, or water dripping noise from plastic parts or defrost cycle, you don’t need to do anything, as this is a normal sound that does not affect the performance of the fridge.
- For a vibrating noise from an improper leveling or stabilization, you can fix it by moving any objects away from the fridge and adjusting the leveling feet at the bottom of the fridge.
- For an air leaking noise from a pressure difference inside the fridge, you don’t need to do anything, as this is a normal sound that does not affect the performance of the fridge.
How To Prevent The Noise Issue On Your LG Fridge
To prevent the noise issue on your LG fridge, you can follow these tips:
- Make sure that there is enough clearance around the fridge to allow proper airflow and ventilation. The recommended clearance is at least 2 inches on the sides, 2 inches on the top, and 4 inches on the back of the fridge.
- Clean the fan and coils regularly to remove any dust or debris that may obstruct or damage them. The fan and coils are located at the back or bottom of the fridge and help to remove heat from the compressor and the fridge. You can use a vacuum cleaner or a soft brush to clean them gently.
- Unjam the ice maker if it is stuck or making too much or too little ice. The ice maker is located inside the freezer or the left door of the fridge and produces ice cubes for your drinks and beverages. You can unjam the ice maker by removing any ice clumps or foreign objects from the ice bin or the ice tray. You can also turn off the ice maker by pressing the power switch or button on the ice maker or on the control panel.
- Install a water hammer arrestor if you hear a loud banging noise when the water valve opens or closes. The water hammer arrestor is a device that absorbs the shock wave caused by the sudden change in water pressure when the water valve opens or closes. You can install a water hammer arrestor on the water supply line behind or under the fridge.
- Replace the ice maker if it is not working properly or making too much noise. The ice maker may wear out or break down over time, causing problems such as no ice, too much ice, small ice, cloudy ice, or noisy operation. You can replace the ice maker by following the instructions in your owner’s manual or calling a professional for assistance.
Conclusion
Your LG fridge is making noise because of various reasons, such as insufficient clearance, obstructed or defective fan, dirty condenser coils, jammed ice maker, water hammering, and a nonworking ice maker. To fix the noise issue, you need to check the clearance around the fridge, clean the fan and coils, unjam the ice maker, install a water hammer arrestor, and replace the ice maker if needed. To prevent the noise issue, you need to maintain proper airflow and ventilation around the fridge, clean the fan and coils regularly, unjam the ice maker periodically, install a water hammer arrestor if necessary, and replace the ice maker when it wears out or breaks down. By following these steps, you can enjoy your LG fridge without any annoying noise!
