    Most common repairs needed to fix a LG refrigerator

    Defrost Drain Replacement

    When the defrost drain is clogged, frost and ice melting from the evaporator fins during the defrost cycle won’t be able to drain away, causing an overflow of water in the drain pan and leading to water leaking underneath the refrigerator. To prevent potential damage to the floor and refrigerator if leaks are noticed, have a Sears Home Services professional inspect the refrigerator to address and rectify the clogged defrost drain promptly.


    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.

    What to expect when you experience an LG refrigerator leaking from bottom issue

    How is the leaking from bottom problem fixed?

    Correcting most leaking from bottom problems usually involves replacing the defrost drain, ice maker assembly or compressor. 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 refrigerator that is leaking from bottom

    When the refrigerator is leaking from bottom 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 leaking from bottom 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.

    What to do When You Find Your LG Refrigerator Leaking Water Underneath

    Cleaning up the water to prevent damage to your kitchen flooring and surrounding cabinets is the first step in dealing with your LG refrigerator leaking water underneath.

    Finding the source of water leaking underneath your LG refrigerator is just as important so you can resolve the problem permanently.

    Here are practical tips for finding the source of water leaking underneath your fridge and preventing continued leaking.

    • Check the defrost drain pan. As you pull the refrigerator out to clean up the leaking water, unplug the fridge and remove the machine compartment cover at the bottom of the back panel. Check the defrost drain pan for a crack or damage that could cause the leak. Replace the defrost drain pan if it’s cracked or damaged and leaking.
    • If the defrost drain pan is full and overflowing, check for sources of air leaks into the refrigerator such as loose or cracked refrigerator and freezer door gaskets. Replace any worn or damaged door gaskets to eliminate air leaks causing excessive frost and condensate that overflows the drain pan.
    • A frozen or clogged defrost drain tube can also cause leaking underneath your LG refrigerator. You may also see water leaking into the freezer compartment when the defrost drain tube is frozen or clogged. Schedule repair service to have a Sears Home Services technician clear the defrost drain tube so the water stops leaking underneath your fridge.

    Taking quick action to prevent continued leaking underneath your LG refrigerator is important to keep your kitchen safe and prevent damage to cabinets and flooring. Count on Sears Home Services to help you resolve this problem if you're unable to find the source of the leak and fix the issue on your own.

    Refrigerant is a chemical compound used in HVAC systems and refrigerators to absorb heat from the environment by cycling through states of evaporation and condensation, enabling the cooling process through its cycle of evaporation and condensation.

    R-12 refrigerant, also known as Freon-12, is a chlorofluorocarbon (CFC) compound that was once widely used in air conditioning systems, refrigerators, and aerosol propellants before its phase-out due to environmental concerns.

    CFC certification refers to the credentialing process that qualifies HVAC technicians to handle chlorofluorocarbons (CFCs) and other refrigerants in a manner that complies with environmental regulations. It is essential for professionals who install, maintain, or repair HVAC systems and refrigeration equipment.

    A refrigerator thermostat is a device within a refrigerator that regulates its temperature by turning the cooling system on and off based on the interior temperature compared to the set desired temperature.
