Most common repairs needed to fix a LG refrigerator
Water Valve Replacement
When a water valve is defective, it impacts the proper functioning of the water dispenser and icemaker. If the water valve fails to open, the icemaker won't receive the water necessary to produce ice, and the dispenser won't dispense water. Additionally, a defective valve may lead to water leakage, particularly near the water valve assembly. In some instances, a malfunctioning water valve can cause the water dispenser or icemaker to cease working entirely. If the water valve fails to close, water flowing into the icemaker may leak to the evaporator and fan, subsequently freezing into a solid block of ice. This impedes airflow, compromising the proper cooling of the refrigerator and freezer compartments.
Icemaker Assembly Replacement
A faulty refrigerator icemaker 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 icemaker's components. A malfunctioning icemaker may lead to water leaks around the icemaker 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 icemaker 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.
PCB Replacement
A defective printed circuit board (PCB) can lead to various failures in a refrigerator, including a lack of power, lack of cooling, and water leaks. The PCB controls communication and power between various components of a refrigerator that control temperature regulation, fan operation, the defrost cycle, icemaker functions, and dispenser functions. If the PCB fails, any or all of these components may stop working. Because so many components can be impacted, Sears Home Services professionals should conduct diagnostic tests on the board to confirm if replacement is necessary.
Why is the LG ice maker not filling with water?
When your ice maker isn't filling with water, the fix is sometimes fairly simple.
Always unplug your refrigerator and shut off the water supply before troubleshooting.
Common Ice Maker Problems
Several problems can interfere with making ice properly or dispensing ice. The ice maker or dispenser could be jammed or broken, a dirty water filter or kinked water line could be blocking water flow or the water inlet valve could be clogged or faulty.
Here are the most common ice maker problems.
Clogged Water Filter
Sediment can eventually build up in water filter when you don’t change it every 6 months to a year. Eventually, the sediment in an unchanged water filter can restrict water flow going to the ice maker.
Replace the fridge water filter every 6 months or yearly according to the guidelines for your refrigerator. This will prevent a clogged water filter from preventing the ice maker from getting water.
Thermostat Set Too Low
When the thermostat for the freezer is set too low, the ice maker module may not detect that ice cubes are frozen. The ice maker won’t cycle and produce ice if temperature isn’t low enough in the freezer.
If the thermostat is set to keep the freezer at too low of a temperature, then the water supply line going to the ice maker can freeze and the ice maker mold won’t fill with water.
In either case, an improper freezer temperature setting can prevent ice production. Set freezer temperature at 0 degrees F to prevent ice maker problems. Is your whirlpool refrigerator no ice?
Water Line Problems
As noted above, the ice maker mold won’t fill with water when its water line freezes. When you hear the ice maker cycling but it doesn’t produce any ice, check for a frozen fill tube in the freezer or ice maker compartment. Defrost the frozen water line and the ice maker will likely start working.
Water Valve Issues
A broken water valve won’t open to fill the ice maker mold with water to produce ice. Also, a leaky water valve will cause the ice maker to overfill and the ice maker will likely jam when attempting to eject ice cubes. A leaky water valve can also cause the water fill line to freeze. Replace the water valve when it doesn’t open or shut properly.

What to expect when you experience an LG refrigerator icemaker not filling with water issue
How is the icemaker not filling with water issue fixed?
Correcting most refrigerator icemaker not filling with water problems usually involves replacing the water valve, icemaker assembly, or PCB. 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 icemaker not filling with water problem
When a refrigerator icemaker is not filling with water, it can be for many reasons. To avoid replacing unneeded parts, we recommend scheduling LG ice maker repair with a local Sears Home Services professional who can 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 icemaker not filling with water 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.

Glossary Terms
A dual ice maker is a feature in some refrigerators that includes two separate ice makers: one in the fridge compartment and another in the freezer section. This setup doubles the appliance's ice-making capacity.
A French-door refrigerator features two doors that open side-by-side on the top section for the refrigerator compartment, with a bottom freezer drawer, combining style, efficiency, and easy access to both refrigerated and frozen goods.
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.
