This Part Fixes These Problems

Ice Maker Not Making Ice

The single-coil valve solenoid fails or clogs, cutting off water supply to the ice maker. Replacing the valve restores normal ice production.

Water Dispenser Not Working or Slow

A restricted or defective inlet valve starves the dispenser of adequate water pressure, resulting in a slow trickle or no water at the door.

Refrigerator Leaking Water

A cracked valve body, worn internal seal, or failed solenoid can cause water to drip from the rear lower section of the refrigerator onto the floor.

Small or Misshapen Ice Cubes

Partial valve restriction reduces water fill volume per cycle, causing the ice maker to produce undersized, hollow, or irregularly shaped cubes.

Valve Humming or Running Continuously

A stuck-open solenoid or worn valve seat prevents the valve from fully closing, leading to constant water noise, running sounds, or uncontrolled dripping.

💡 Pro Tip: How to Confirm Your Water Inlet Valve Has Failed

Your part is likely the culprit if you notice any of the following:

⚠️ Ice maker stops producing ice entirely or makes small, hollow, or misshapen cubes

⚠️ Door water dispenser produces little to no water or dispenses very slowly

⚠️ Water leaks from the rear lower area of the refrigerator near the valve

⚠️ Valve buzzes, hums, or runs continuously without stopping water flow

🔎 Diagnosis tip: Use a multimeter to test solenoid coil resistance across the 2-pin connector terminals. A healthy single-coil valve typically reads 200–500 Ω. An open circuit (OL) reading confirms the solenoid has failed and the valve must be replaced — do not attempt to clean or rebuild a clogged inlet valve, as internal mesh damage will cause repeat failures.

Questions & Answers

Is this a single-coil or dual-coil valve? Will it work for both the ice maker and water dispenser?
Answered by Support Team  ·  Mar 15, 2024
This is a single-coil (single solenoid) primary water inlet valve. It controls the main water inlet at the rear of the refrigerator. On many LG French-door models, a second dual-solenoid valve (MJX41869202) is located inside the fresh-food door and handles the split between the ice maker and dispenser. The MJX41178908 handles the primary water supply line connection at the back of the unit. Confirm your model's valve layout before ordering.
Does this part also fit Kenmore refrigerators?
Answered by Support Team  ·  Nov 20, 2023
Yes. Many Kenmore refrigerators in the 795.71xxx series are LG-built units and use the same MJX41178908 primary water inlet valve. Confirmed compatible Kenmore models include 79571022010, 79571023010, 79571024010, 79571026010, 79571029010, 79572022110, 79577562600, 79578502800, and 79578509800. Always verify your full model number before purchase.
My fridge is making a buzzing or humming sound near the back. Could this valve be the cause?
Answered by Support Team  ·  Jan 8, 2025
Very likely, yes. A buzzing or humming noise from the rear lower section of the refrigerator often indicates the solenoid coil is struggling to open or close fully — commonly caused by mineral deposits from hard water, coil degradation, or a worn valve seat. We recommend testing the solenoid coil resistance with a multimeter across the 2-pin terminals. An open-circuit reading (OL) or a reading outside the expected 200–500 Ω range confirms valve failure. Do not attempt to clean the valve internally, as this typically makes the problem worse.
What tools do I need to install this valve, and how long does the job take?
Answered by Support Team  ·  Jul 22, 2024
For most LG and Kenmore models this is a 15–30 minute repair requiring only a Phillips screwdriver, needle-nose pliers, and a towel or small bucket for water drips. Work gloves are recommended for hand protection. No special refrigeration tools are needed. Always unplug the refrigerator and shut off the water supply before starting. The valve is located behind the lower rear access panel.
What cross-reference part numbers does this valve replace?
Answered by Support Team  ·  Feb 10, 2026
This valve is a verified replacement for the following part numbers: AP4451762, PS3536019, AH3536019, EA3536019, EAP3536019, 1398828, 5221JA2011J, 5221JA2011B, 5221JA2011P, and PD00005215. If you have one of these numbers on your original part or in your model's parts diagram, this valve is the correct replacement.
