The Icemaker Assembly is an OEM part for LG refrigerators. It is responsible for producing and storing ice within the freezer compartment.

You should replace the icemaker assembly if it becomes faulty. Causes of a bad icemaker assembly can include wear and tear from regular use, mineral buildup from hard water, or failures in the mechanical or electronic components. These issues can lead to inconsistent ice production or complete failure to produce ice.

Symptoms of a bad icemaker assembly include:

• The icemaker not producing ice
• Leaking water around the icemaker
• Ice cubes that are misshapen or smaller than usual
• Unusual noises coming from the icemaker

This OEM LG part is also compatible with Sears/Kenmore.

This is the water injector tube for select refrigerators. It routes water from the supply system into the appropriate internal channel, helping ensure proper flow to the ice maker or dispenser and preventing leaks at the connection point.

• Directs water from the valve/supply line into the refrigerator's internal water path
• Helps restore proper ice maker/dispenser filling
• Common symptoms: leaking at the rear/under the unit, poor or no ice production, slow or no dispenser flow

• Unplug the refrigerator and shut off the water supply before service
• Have a towel ready to catch residual water from the line
• Note tube routing and connection points before removal; push-to-connect fittings may be present
• After installation, turn water on and check all joints for leaks

The Water Nozzle is an OEM replacement part for LG refrigerators. It is a component within the refrigerator's ice maker and water dispenser system. The water nozzle controls the flow of water into the ice making mold or water dispenser functions.

Symptoms of a bad water nozzle include:

• Slow filling or inability to fill the ice-making mold 
• Inconsistent or weak water dispensing from the refrigerator's door 
• Leaks or water drips around the ice maker or water dispenser area

Causes of a faulty water nozzle can be mineral deposits accumulating over time, wear and tear from heavy use, or damage due to impact or freezes. 

This part is also compatible with many Kenmore side-by-side refrigerator models.

The Water Valve is an OEM part for LG refrigerators. This valve controls the flow of water to the refrigerator's ice maker and water dispenser, ensuring a steady and regulated supply.

Causes of a bad water valve can include wear and tear over time, mineral deposits from hard water clogging the valve, electrical issues, or physical damage from mishandling. These problems can result in the valve failing to open or close properly.

Symptoms of a bad water valve include:

• No water dispensing from the refrigerator
• The ice maker not producing ice
• Leaks around the valve area
• Unusual noises when the valve is operating
• Low water pressure or flow

This OEM LG part is also compatible with Sears/Kenmore models.

The Water Supply Tube (1/4" O.D.) is an OEM part for LG refrigerators. It transports water from the household water line to the refrigerator’s water dispenser and ice maker, ensuring a steady and reliable supply of water for these functions.

Causes of a bad water supply tube can include wear and tear over time, kinks or bends restricting water flow, or leaks due to cracks or punctures.

Symptoms of a bad Water Supply Tube include:

• Leaks or water pooling behind or under the refrigerator
• Reduced or no water flow to the dispenser or ice maker
• Visible cracks or kinks in the tube
• Ice maker not producing ice or dispensing water intermittently

This OEM LG part is also compatible with some Kenmore models.

This holder is a small mounting bracket that secures a mating component in place inside the appliance. Replacing a cracked or missing holder restores a firm, rattle-free fit and proper alignment.

• Provides a stable mount for the designated part
• Prevents shifting and vibration that can cause noise or premature wear
• Common signs of failure: broken tabs, stress cracks, or the attached part sagging or falling out
• When damaged, the connected component may be loose, noisy, or misaligned

• Disconnect power; if working near water tubing, also shut off the water supply
• Note the original orientation and mounting points; take a photo before removal
• Reuse existing fasteners and avoid overtightening to prevent cracking the plastic
• Ensure the attached component is secure and clears any moving parts before restoring power
