    Most common repairs needed to fix a LG refrigerator

    Ice Maker Assembly Replacement

    A faulty refrigerator ice maker can have diverse effects, impacting various aspects of the refrigerator's operation, including its ability to make ice. Increased noise during the ice-making process could indicate a problem in the ice maker's components. A malfunctioning ice maker may lead to water leaks around the ice maker assembly, potentially causing water puddles in and around the refrigerator. If the bail arm fails to shut off ice production, it could result in the ice maker drawer jamming due to an overproduction of ice, potentially leading to damage to the drawer or adjacent shelf. The failure of other components in a refrigerator that stops cooling will affect ice production, so a thorough inspection of the refrigerator by a Sears Home Services professional is recommended for an accurate diagnosis.


    Compressor Replacement

    A locked refrigerator compressor can exhibit several symptoms indicative of a malfunction. The most noticeable sign is a lack of cooling in the refrigerator compartment, leading to elevated temperatures and the potential for food spoilage. The freezer may also fail to maintain the desired freezing temperatures, resulting in no ice production from the ice maker or dispenser. Additionally, you'll observe that the compressor is unusually silent or fails to produce its typical humming sound during operation. In some cases, the compressor may attempt to start but fail, resulting in repeated clicking noises. The inability of the compressor to circulate refrigerant properly can affect the defrosting process, leading to ice buildup in the freezer. Furthermore, a faulty compressor could send a sudden influx of melting frost to the drain line, causing it to back up, preventing adequate draining, and potentially causing water leaks.

    Electronic Control Board Replacement

    A defective electronic control board can lead to various failures in a refrigerator, including a lack of power or cooling and water leaking. This is because the board serves as the brain of the refrigerator, controlling crucial operations such as regulating internal temperatures, running fans, managing defrost cycles, overseeing the ice maker, and controlling dispenser functions. If the electronic control board malfunctions, it can disrupt communication between many different components, including automatic doors if equipped. A failing board may cause a chattering or clicking noise from the refrigerator and may emit a burning odor. Due to the potential impact on multiple components, it is advisable to have a Sears Home Services professional conduct diagnostic tests on the board to confirm if replacement is necessary.

    What to expect when you experience an LG refrigerator makes noise issue

    How is the makes noise problem fixed?

    Correcting most makes noise problems usually involves replacing the ice maker assembly, compressor or electronic control board. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.

    Sears Home Services recommendations for a noisy refrigerator

    When the refrigerator makes noise it can be for many reasons. To avoid replacing unneeded parts we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of refrigerator failures.

    What to look out for with a refrigerator that makes noise diagnosis

    Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your refrigerator problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.

    LG Refrigerator Making Noise Troubleshooting

    Your LG refrigerator will make certain noises that are normal.

    • The compressor and fans will make faint humming noises as they run.
    • You’ll heart the clunk of ice falling from the ice maker as it ejects a batch of ice. You’ll then hear the buzz of the water valve filling the ice mold to make a new batch of ice.
    • You may hear sizzling or popping noise followed by water dripping as the automatic defrost system melts frost and ice from the evaporator fins.
    • You may hear random cracking or popping noises as parts inside the fridge expand and contract during temperature changes due to thermal expansion and contraction.

    If you hear loud and unusual noises that don’t resemble these normal noises, then something may be wrong inside the fridge. Here are some abnormal noises you may hear.

    • Loud buzzing of the evaporator fan hitting excessive ice and frost buildup on the bottom of the evaporator fins.
    • Clicking and snapping noises coming from the ice maker because an ice cube is stuck in the ejector arms and jamming the ice maker.
    • Knocking or loud whining coming from the compressor because of motor mount problems or a worn bearing.

    When you hear the unusual noises coming from your LG refrigerator, schedule repair service and we’ll send a Sears Home Services technician to your home to fix the problem.

    What to do When You Hear Your LG Refrigerator Making a Loud Noise

    Try to find the location when you hear your LG refrigerator making a loud noise. Knowing the location will help you troubleshoot the problem causing the noise.

    • For a loud buzzing noise coming from the freezer, check for excessive frost in the freezer compartment. Frost buildup on the bottom of the evaporator could be hitting the evaporator fan blades to cause the noise. You can temporarily get rid of this noise by safely storing food and manually defrosting the evaporator in the freezer. Shut off cooling or unplug the fridge for 4 hours and open the fridge and freezer doors to frost and ice melt from the evaporator. Turn the fridge back on or plug in the power cord and see if the noise ended. If it did, check the refrigerator and freezer door gaskets for cracks or damage that could be allowing warm, moist air into the cabinet to cause the excessive frost. Replace any door gasket that is damaged. This may permanently fix the buzzing noise coming from the freezer. If the noise remains after defrost or returns in a few days, a problem with the automatic defrost system could be causing the noise. Schedule repair service to have a Sears Home Services technician fix the noise problem.
    • If your LG refrigerator is making loud noise such as whining coming from underneath the fridge, a problem with the compressor or condenser fan may be making the noise. A service technician will typically need to diagnose and repair the refrigerator when you hear this type of noise.
    • Clicking and snapping coming from the icemaker can be caused by an ice cube caught in the ejector arms. Unplug the refrigerator and check for an ice cube or cubes stuck in that area. Clear ice cubes from the ejector arms and the noise will likely end. If the ice maker doesn’t work after removing the stuck ice cube or cubes, schedule service and we’ll have a Sears Home Services technician visit your home and replace the ice maker assembly.

    LG Refrigerator Making Humming Noise

    Humming noise in your LG refrigerator can be caused by the compressor, condenser fan or evaporator fan.

    If the humming noise is faint and the refrigerator is cooling properly, the sound may be normal.

    If the humming noise is louder than you’re accustomed to hearing, the sound warrants investigation. Try to find the location of the humming noise.

    • Humming noise coming from inside the freezer often indicates that the evaporator fan blade is hitting excessive frost buildup on the bottom of the evaporator fins. You can typically eliminate this noise by manually defrosting the evaporator and eliminating the source of excess frost. To manually defrost the evaporator, safely store food and turn off cooling or unplug the fridge power cord. Open the freezer door and refrigerator door and allow the fridge to defrost for 4 hours. Restore power and cooling to the fridge and see if the humming noise stopped. If it did, then you likely find the cause of the humming noise. To keep the noise from returning, check the refrigerator and freezer door gaskets for cracks or damage. Replace a door gasket if it’s damaged and this will help prevent excessive frost buildup and the humming noise from the evaporator fan. If the noise returns and you found no air leaks into the refrigerator, then a failure of the automatic defrost system is likely causing the humming noise. Have a service technician diagnose and repair the automatic defrost system in your fridge.
    • If the humming noise is coming from the compressor, it may be overheating due to dirty condenser coils. Unplug the refrigerator and clean the condenser coils and see if the noise ends. If not, schedule service to have a technician examine the fridge and fix the problem.
    • When the humming noise is coming from the condenser fan, unplug the fridge and check the condenser fan blades for dust buildup and debris. Clean the fan blades if necessary. Check the fan mounting screws and tighten them if necessary. If the humming noise doesn’t end after following these basic troubleshooting tips, you’ll likely need to schedule refrigerator repair service to have a technician check the fan and replace it if necessary.

    Troubleshooting an LG Refrigerator Loud Knocking Noise

    An LG refrigerator loud knocking noise is often caused by loose compressor motor mounts or an internal problem with the compressor.

    If compressor motor mounts are loose, you may be able to eliminate the loud knocking noise yourself by unplugging the refrigerator and tightening those fasteners using this procedure.

    1. Remove the machine compartment cover on the back of the fridge to access the compressor.
    2. Allow the compressor to cool completely.
    3. Tighten the motor mounts using a wrench and then reinstall the machine compartment cover.
    4. Plug in the power cord to restore electrical power to the fridge.

    If this doesn’t fix the loud knocking noise, you’ll likely need to schedule refrigerator repair service to have a Sears Home Services technician fix the problem.
