LG & Kenmore Refrigerator Water Inlet Valve Parts — Models & Compatibility

If you've noticed water pooling under your LG or Kenmore refrigerator, or your ice maker's suddenly producing those tiny, sad half-cubes, there's a good chance your water inlet valve has called it quits. This hub covers the 5220JB2010 water inlet valve—a critical component that controls water flow to both your ice maker and dispenser across dozens of LG and Kenmore refrigerator models.

Is This the Right Part for Your Model?

Before you order, you'll need to verify compatibility with your specific model. Your model number's typically on a sticker inside the fresh food compartment—usually on the left or right wall, sometimes on the ceiling. For LG models, look for numbers starting with LRDC or LFC. Kenmore owners, you're hunting for a number starting with 795. Cross-reference it with our compatibility list below to confirm this valve fits your unit.

About This Replacement Part

The 5220JB2010 water inlet valve (also sold as 5220JB2010A, 5220JB2010W, and 5220JB2005A—they're all the same part) is an electrically-controlled solenoid valve that opens and closes to supply water when your ice maker calls for it or when you press the dispenser paddle. When it fails, you'll typically see one of three things: puddles forming underneath the fridge from a leaking valve, complete failure to supply water to the ice maker or dispenser, or frustratingly slow water output that makes filling a glass feel like watching paint dry. The valve contains rubber seals and plastic components that wear out over time, especially if you've got hard water or sediment in your supply line. Most failures happen after 5-7 years of regular use.

Installation Overview

This is a straightforward repair that most homeowners can tackle in under an hour. You'll be working behind the refrigerator, so you'll need to pull the unit away from the wall. The critical first step—and I can't stress this enough—is to disconnect both the power cord and shut off the water supply line before you touch anything. The valve typically mounts to the back panel with a bracket and connects via push-fit or compression fittings. You don't need specialized tools, just a quarter-inch nut driver and possibly an adjustable wrench depending on your water line connection type.

Technical Specifications

This valve operates on standard 120V household current and includes two solenoid coils—one for the ice maker circuit, one for the dispenser circuit. The inlet connection accepts a standard ¼-inch compression fitting or push-fit connector depending on your model. Output ports vary by model but typically include one or two ¼-inch connections for ice maker and dispenser lines. Replaces manufacturer part numbers AP4444451 and PS3527440 along with the alternate SKUs listed above.

Why This Part Fails

Water inlet valves don't last forever, and there are a few common culprits behind their demise. Hard water deposits build up on the valve seat and solenoid components, preventing proper closure and causing leaks. If you've ever heard a humming noise coming from behind the fridge, that's often a valve trying to open against mineral buildup. The rubber seals inside deteriorate with age—especially if you live somewhere with chlorinated water—leading to slow leaks that eventually become obvious puddles. And sometimes the solenoid coils simply burn out, leaving you with no water flow at all. If your house has experienced any water hammer (that banging sound when pipes shut off quickly), that pressure spike can damage the valve's internal components too.

Related Symptoms to Watch For

Before your valve fails completely, you might notice warning signs: ice cubes that are smaller than usual or have hollow centers, a dispenser that takes forever to fill a glass, or intermittent water flow that works fine one day and barely trickles the next. Sometimes you'll hear clicking sounds from behind the fridge as the valve attempts to operate but can't fully open or close. Don't ignore these symptoms—a leaking valve can cause water damage to your floor and subflooring if it goes unnoticed for too long.
