W10585391 Whirlpool Refrigerator Valve is a replacement inlet/solenoid valve used in many Whirlpool-brand refrigerators to control water flow to the ice maker and door water dispenser. It is a mechanically actuated valve assembly with one or more solenoid-operated ports, seals, and mounting flanges; electrically it is driven by the refrigerator control board and mechanically it interfaces with the incoming household water supply and internal plumbing.
Inside the appliance, the W10585391 valve regulates when and how much water is allowed into the ice maker fill cup and the dispenser lines. The valve acts as a normally-closed barrier that opens when its solenoid(s) receive the appropriate control voltage, allowing pressurized water to flow through dedicated outlets. It therefore interacts directly with the household water inlet, the refrigerator’s internal tubing and check valves, the ice maker fill mechanism, the dispenser actuator assembly, the control electronics that supply the solenoid voltage, and any inline filters or pressure-reducing components that affect flow rate or pressure.
In this article you will find a technical overview of the valve’s function and typical construction, guidance on model and electrical/mechanical compatibility with different refrigerator platforms, common failure symptoms (such as no water, slow fills, continuous filling, or external/internal leaks), diagnostic and troubleshooting approaches a technician can use (electrical checks, pressure/flow verification, leak inspection), and practical considerations for safe replacement, mounting and plumbing reconnection.The coverage is intended to help technicians, engineers and informed appliance owners assess whether the valve is the source of a problem and to plan a correct, code-compliant repair or replacement.

Function and Role of the Refrigerator Water Inlet Valve in Ice-Making and Dispensing Systems
The water inlet valve in a refrigerator is a solenoid-actuated flow control that meters mains water to both the ice-making assembly and the door dispenser.The W10585391 Whirlpool Refrigerator Valve serves as that interface on compatible Whirlpool models: when the control board commands a fill, an electrical pulse energizes the solenoid, lifting the internal plunger and allowing a measured volume of water to pass through the valve ports to the ice mold or dispenser. The valve’s sealing seat, diaphragm, and port geometry determine flow rate and shutoff reliability, so correct physical mounting, matching port count, and compatible electrical connections are required for proper operation and to avoid leaks or incorrect fill volumes.
- Symptoms of valve faults: no fill (stuck closed or clogged screen), continuous flow or leaks (failed seat/diaphragm), buzzing or intermittent operation (weak coil or poor electrical drive), and slow fills (low inlet pressure or partial blockage).
- Key features to confirm when replacing: matching port configuration, connector type, and valve actuation voltage/drive characteristics.
- Simple diagnostic checks: verify incoming water pressure, inspect the inlet screen for debris, measure coil continuity, and confirm voltage at the valve during a commanded fill.
In field service, technicians isolate the problem by combining electrical and hydraulic checks: verify coil resistance and apply supply voltage while monitoring for flow and listening for abnormal coil noise; inspect the inlet screen and supply line for mineral deposits or debris that can mimic valve failure. Replacement practice includes shutting off and draining the supply, fitting a matching valve with correct port orientation, and performing post-installation flush and diagnostic fill cycles to confirm correct volume and leak-free operation. Because system symptoms overlap (for example, a clogged filter or low household pressure can produce slow fills), confirm both the valve function and the upstream supply conditions before concluding a valve replacement is required.

How the W10585391 Whirlpool Refrigerator Valve Works: Solenoid Operation, Flow Channels, and Control Interface
The W10585391 Whirlpool Refrigerator Valve is an electrically actuated multichannel inlet valve that meters household water into the icemaker and door dispenser. Each outlet is controlled by a separate solenoid; when the refrigerator control sends power to a solenoid, the plunger inside the valve retracts from its seat and opens a dedicated flow channel to the selected output. The valve body contains discrete passageways and check seats to prevent cross-flow between the icemaker and dispenser circuits, and many replacement valves for Whirlpool-family refrigerators are designed to match the original port layout and coil ratings.Verify compatibility by matching the part number, connector pinout, and water pressure specifications to the refrigerator model before installation to avoid mismatched flow characteristics or electrical loading on the control board.
The refrigerator control board or user-interface module manages the valve by switching line voltage to the appropriate solenoid for a controlled duration, so the valve’s behavior depends on both the coil electrical integrity and the water supply pressure. technicians commonly diagnose valve faults by confirming that the control is sending a drive signal, listening for the solenoid “click,” checking coil continuity with a multimeter, and inspecting the valve for mineral buildup or debris at inlet screens that can prevent sealing. Intermittent dispense or a continuously running drip usually indicates a stuck-open seat or failed solenoid; a no-flow condition with a confirmed drive signal points to a clogged inlet or a mechanically seized plunger. practical repair decisions consider whether the failure mode is electrical (coil/harness/control),mechanical (seat/plunger/debris),or hydraulic (low supply pressure),as replacement of the W10585391 Whirlpool Refrigerator Valve is appropriate when the valve body or solenoids are damaged or cannot be cleaned reliably.
- Common diagnostic checks: verify drive voltage at the connector, measure coil continuity, listen for actuation, and inspect inlet screen and outlet seals.
- Typical failure symptoms: no water, intermittent flow, water leaking, or cross-feed between circuits.
- When replacing, ensure matching port configuration and coil voltage to avoid control-board stress or plumbing mismatches.

Common Failure Symptoms and Diagnostic Tests for Water Inlet Valve Malfunction
The W10585391 Whirlpool Refrigerator Valve is the solenoid-operated inlet assembly that meters water to both the dispenser and the ice maker. It contains one or more electrically actuated diaphragms that open when the control board supplies the correct voltage,and it relies on adequate inlet water pressure and a clear inlet screen to operate as designed. Physically, the valve is an OEM-style replacement used across many Whirlpool-family refrigerators; however, fit and coil voltage can vary by model, so technicians should confirm part compatibility and connector type before installation.
- No water from dispenser or ice maker
- Slow or intermittent water flow
- Continuous filling or water running into drain
- Loud humming from valve when energized
- Visible leaks at valve or fittings
Diagnostic testing combines electrical and hydraulic checks: measure coil continuity with a multimeter (coils typically read from a few hundred to a few thousand ohms depending on design), verify the control board supplies the rated voltage at the valve harness while requesting water, and confirm inlet line pressure and flow by disconnecting the outlet hose and briefly activating the valve. If the coil has correct resistance and receives the correct voltage but the valve does not pass water, the valve is likely mechanically stuck or clogged-clean screens and inspect for mineral deposits or debris. Conversely, if the valve hums but never fully opens, compare measured voltage under load and inlet pressure to expected values; a bench test with the appropriate rated voltage can distinguish electrical failure from hydraulic obstruction.
| Item | Description |
|---|---|
| Typical coil resistance | Model-dependent; generally on the order of a few hundred to a few thousand ohms. Use service documentation for exact target values. |
| Common bench/field check | Verify continuity, apply rated voltage briefly to observe mechanical opening, and confirm adequate inlet pressure and unobstructed screens. |
Compatibility,Model Fitment,Replacement Considerations,and Step-by-Step Installation Procedures
The W10585391 Whirlpool Refrigerator Valve is the OEM water inlet/solenoid assembly that meters water to the dispenser and ice maker by opening and closing internal passages in response to the refrigerator control signals. Functionally,it contains one or more solenoid-actuated ports,an inlet screen to trap debris,and standardized mounting and connection points; failures commonly arise from diaphragm or spool seizure,corrosion of contacts,or clogged inlet screens that reduce flow. Compatibility depends on the valve’s mechanical mounting pattern, inlet/outlet fitting type (push-fit vs. hose barb), and the refrigerator model’s harness and connector style, so technicians should confirm the refrigerator model number and OEM cross-reference rather than relying solely on dimensional similarity.
Replacement requires verification of both physical fit and hydraulic/electrical interface and a methodical installation sequence to avoid leaks or electrical faults. Typical practical considerations include transferring or replacing support grommets and brackets, inspecting and cleaning or replacing the supply line and filter screen, and performing a controlled leak and actuation test after reassembly; avoid using thread sealants on push-fit connections and do not overtighten plastic fittings. The following checklist summarizes the safe replacement sequence and key post-installation checks.
- Shut off water supply and disconnect power to the refrigerator.
- Remove access panel, depressurize water line, and note valve orientation and wiring placement.
- Disconnect electrical connectors and water lines (capture residual water), remove mounting fasteners, and install the replacement valve in the same orientation.
- Reattach hoses and harness, restore water supply gradually while checking for leaks, then restore power and run dispenser/ice cycles to verify operation.

Q&A
what is the W10585391 Whirlpool refrigerator valve and what does it do?
The W10585391 is a replacement water inlet/solenoid valve used on many Whirlpool, Maytag, and KitchenAid refrigerators. It controls water flow from the house supply into the refrigerator for the ice maker and water dispenser. Electrical coils on the valve open and close internal diaphragms when the refrigerator requests water.
What are common symptoms that the valve is failing?
Common signs include no water or very low water flow from the dispenser or ice maker, water leaking at the back of the fridge or inside the cabinet, a humming or buzzing noise from the valve, the ice maker not filling, or the valve clicking repeatedly. Some symptoms are also caused by low supply pressure, a clogged filter, or a faulty control board, so diagnosis is vital.
How do I troubleshoot whether the valve or something else (filter,water line,control) is the problem?
Start simple: make sure the house shut‑off valve is fully open and the water line isn’t kinked. Replace or bypass the inline water filter to rule out a clogged filter. Check for a frozen or pinched line inside the freezer. If those are ok, unplug the refrigerator, remove the rear access panel, and visually inspect the valve inlet screen for debris. With the fridge plugged in and an assistant calling for water (press dispenser or initiate ice maker fill), measure for the proper control voltage at the valve terminals (usually ≈120 VAC on U.S. models). If voltage is present and the valve doesn’t open, the valve is bad. If there is no voltage, the problem is upstream (control board, harness, switches).
How do I test the W10585391 valve electrically and mechanically?
with power applied and a water demand active, use a multimeter to check for AC voltage at the valve’s solenoid terminals (consult model/service manual for expected voltage-many U.S. models use ~120 VAC). If the correct voltage is present and the valve doesn’t open, the coil or internal diaphragm has likely failed. If you remove power, you can also test coil continuity for an open circuit (open indicates a bad coil). Do not perform live tests unless you are agreeable and take appropriate safety precautions. When testing manually,make sure the water supply is turned off before disconnecting any fittings.
Can a clogged inlet screen cause valve problems and how do I clean it?
Yes. Sediment, mineral deposits, and debris can clog the inlet screen on the valve, restricting flow or preventing sealing. To check, turn off the water supply and electrical power, remove the valve, and inspect the inlet screen (located where the supply line connects).Carefully clean with a small brush or flush with water. If the screen is damaged or the valve still performs poorly after cleaning, replacement is recommended.
How do I replace the W10585391 valve and what safety steps should I follow?
Replacement steps: shut off the water supply, unplug the refrigerator, and move it away from the wall.Remove the rear access panel to reach the valve. Place towels to catch residual water, disconnect the water lines (use a wrench or disconnect fittings), remove the electrical connectors, and unfasten the valve mounting screws. Install the new valve in reverse order, tighten fittings securely (use appropriate thread sealant if recommended), restore power and water, and check for leaks while cycling the dispenser/ice maker. Always turn power and water off before beginning and follow the refrigerator’s service manual for model‑specific instructions.
is the W10585391 compatible with my refrigerator model and where can I verify that?
W10585391 is used on many Whirlpool family refrigerators, but part compatibility depends on the exact refrigerator model and year. Verify compatibility by checking the part number against your refrigerator’s model number using the manufacturer’s parts lookup, an authorized parts dealer, or the refrigerator’s service manual. Do not assume interchangeability without verification.
What typically causes the valve to fail and how long do these valves usually last?
Valves fail due to normal wear of diaphragms and seals, mineral buildup, debris clogging, water hammer or pressure spikes, electrical coil burnout, or corrosion. Life expectancy varies by water quality and usage but many valves last several years; hard water and heavy use shorten life. Preventive steps include using a quality water filter, maintaining proper water pressure, and cleaning inlet screens when servicing the appliance.
