Parts for Lg LFC21770ST/06: Water And Ice Maker Parts

This ice maker lever is the mechanical arm that controls ice production by interacting with the ice maker's on/off and level-sensing mechanism. Replacing a broken or missing lever restores proper operation and helps prevent overfilling or no-ice conditions.

• Acts as the ice maker's shut-off arm to regulate ice production
• Lowers to allow ice making; raises to stop when the bin is full
• Common symptoms: ice maker won't stop making ice, no ice when arm is stuck up, broken/missing lever, lever won't stay in position
• Helps ensure consistent, reliable ice production control

• Disconnect power and shut off water before service
• Remove the ice bin to access the ice maker; gently release the lever from its pivots/linkage
• Note lever orientation; transfer and reuse any original springs, clips, or fasteners
• Reinstall components, restore power, and verify free up/down movement of the arm

The Ice Maker Assembly Kit is an OEM part for LG refrigerators. This kit includes all the components necessary to produce ice efficiently, ensuring a steady supply of ice cubes for your household needs. This particular 12-cube ice maker assembly features a 10-wire harness. 

Causes of a bad ice maker assembly can include wear and tear over time, issues with the water supply, or mechanical malfunctions that prevent the ice maker from operating correctly. These issues can lead to a reduction in ice production or complete failure of the ice maker.

Symptoms of a bad ice maker assembly include:

• No ice production
• Ice cubes being smaller than usual
• Leaks around the ice maker area
• Unusual noises during the ice-making process

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

The Refrigerator Temperature Sensor is an OEM part for LG refrigerators. This sensor monitors the temperature inside the refrigerator and communicates with the control board to maintain the optimal cooling environment.

Common causes of failure include wear and tear over time, electrical issues, or exposure to moisture. A malfunctioning sensor can lead to inaccurate temperature readings, resulting in improper cooling or freezing.

Symptoms of a bad refrigerator temperature sensor include:

• Inconsistent refrigerator or freezer temperatures
• Food spoiling faster than usual
• Refrigerator running continuously or not running at all
• Error codes displayed on the control panel

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

This water line holder secures and routes the refrigerator's plastic water tube so it stays protected and out of the way. Replacing a damaged holder helps prevent kinks and leaks and keeps water flowing to the dispenser and icemaker.

• Anchors and guides the water tube along the cabinet/door to prevent rubbing and kinking
• Helps maintain proper water flow to the dispenser and ice maker
• Replace if the holder is cracked, missing, or the tube won't stay seated
• Symptoms can include leaks or drips near the hinge/backs, slow or no dispensing, or visibly loose tubing

• Disconnect power and turn off the household water supply before servicing
• Access the holder (often behind a hinge cover, kick plate, or rear panel)
• Note tube routing, then release/remove the old holder and seat the tube in the new holder; reuse existing hardware if present
• Restore water and power; check for leaks and normal dispenser/ice operation

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.

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
