W10585391 Whirlpool Refrigerator Valve is a solenoid-actuated water inlet valve assembly designed for use in Whirlpool refrigerators. As a mechanical-electrical component, it controls the flow of potable water from the household supply into appliance subsystems; the valve typically mounts at the rear lower section of the cabinet and connects to the incoming water tubing and internal distribution lines.
Inside the appliance the valve functions as the primary on/off control for water delivery to the ice maker and to the refrigerated-water dispenser. It interfaces directly with the refrigerator’s water lines, inlet strainer, mounting bracket and sealing hardware, and is actuated by the appliance’s control circuitry. Proper operation depends on a correct mechanical seal, unobstructed flow through the inlet strainer, adequate inlet pressure, and reliable electrical actuation; failures or leaks can affect ice production, dispenser performance, and can create water-damage risks to other components such as the compressor compartment and control electronics.
In this article readers will find a technical overview of the valve’s construction and function, guidance on model compatibility and identification, common failure symptoms and diagnostic checks (including flow and electrical continuity tests), practical troubleshooting steps, and considerations for safe replacement and installation. the goal is to give technicians,engineers,and experienced appliance owners the context and procedures needed to evaluate,diagnose,and replace the W10585391 valve in a controlled,standards-conscious manner.

Function and Role of the Refrigerator Water Inlet Valve in Cooling, Icemaker and Water Dispense Systems
The W10585391 whirlpool Refrigerator Valve is a solenoid-actuated water inlet valve that meters and routes household water into the refrigerator’s icemaker and dispenser circuits. in operation the valve remains closed until the control board or icemaker module applies voltage to the appropriate solenoid; the energized solenoid lifts a diaphragm or poppet,allowing pressurized water to flow through the correct outlet port. Some valves provide separate internally plumbed outlets for the icemaker and dispenser, so a single assembly can control two independent fills. Compatibility when replacing the valve depends on matching the electrical connector type, mounting footprint, inlet/outlet fitting sizes, and the valve’s required control voltage-mechanically similar parts from different model families are not always interchangeable without verifying those parameters.
- Primary functions: route water to ice mold and dispenser, shut off supply when not commanded.
- Common failure modes: stuck-closed (no water), stuck-open (continuous flow or leak), coil open/short (no actuation), internal debris restriction (low flow).
- Replacement considerations: matching port orientation, fitting sizes (compression vs. push-fit), and control-voltage compatibility.
| Item | Description |
|---|---|
| Actuation | solenoid-operated diaphragm/poppet that opens under applied control voltage |
| Ports | Separate outlet ports for icemaker and dispenser; inlet fits standard supply tubing |
| Failure indicators | No dispense, slow fill, continuous leak, or electrical coil failure |
For practical troubleshooting, verify supply-side conditions (filter condition and line pressure) and perform electrical checks at the valve-measure for the presence of control voltage during a dispense or ice-fill cycle and check coil continuity with a multimeter. If the valve gets voltage but does not open, the diaphragm/poppet is highly likely obstructed or worn and the assembly should be replaced; if the valve opens without control voltage or constantly leaks, internal sealing has failed. When installing a replacement such as the W10585391, confirm the valve’s connector pinout and inlet/outlet sizes, secure proper mounting to avoid stress on tubing, and test both the icemaker fill and dispenser functions after installation to ensure correct sequencing from the refrigerator’s control electronics.
How the W10585391 Whirlpool Refrigerator Valve Works Inside the Appliance
The W10585391 Whirlpool Refrigerator Valve is a solenoid-actuated water inlet assembly that meters water to the ice maker and dispenser. Installed at the rear water connection and integrated with the refrigerator’s internal manifold, the valve contains one or more normally-closed diaphragms that open when the control board or ice maker applies an electrical signal, allowing pressurized supply water to pass through discrete outlet ports. Technicians should verify port orientation, mounting holes and connector type for compatibility with specific Whirlpool, Maytag or KitchenAid models before replacement; physical fit and plumbing orientation determine whether the assembly will function correctly in a given cabinet layout.
- Electromechanical operation: solenoid coils energize to lift diaphragms and permit flow.
- Outlet configuration: single or dual ports separate ice-maker and dispenser feeds.
- Common service symptoms: no water (valve fails to open), continuous leaking (stuck open or diaphragm failure), and reduced flow (clogged inlet screen or partial valve seating).
| item | Description |
|---|---|
| Function | Controls timed water delivery to ice maker and dispenser via electrically actuated diaphragms. |
| Location | Mounted at the refrigerator water inlet/manifold at the rear of the cabinet; connects to supply tubing. |
| Diagnostic focus | Check water supply pressure and filter condition, verify electrical call for water at the coil, inspect inlet screen and valve seat for debris. |
Operationally,the valve is driven by short or sustained electrical commands: an ice-maker fill cycle sends a timed pulse to the appropriate solenoid to deliver a measured volume,while dispenser use energizes the valve for the duration of the user request. Valve performance depends on supply pressure, the condition of the internal screens and diaphragms, and correct electrical actuation; for example, low line pressure or a partially blocked inlet filter can mimic an electrical failure by producing inadequate flow. In practise, diagnostics proceed by confirming a valid supply, measuring for a control-board voltage during a call for water, checking coil continuity, and replacing the W10585391 assembly when mechanical or sealing failures are observed.
Common Failure Symptoms and Diagnostic Indicators of Valve Malfunction
The W10585391 Whirlpool Refrigerator Valve controls water delivery to the ice maker and dispenser by opening a solenoid-actuated inlet seat when the control board supplies the proper drive signal. Failures typically originate from either the electrical coil (open circuit, short, or intermittent connection) or mechanical obstruction at the valve seat or inlet screen (mineral buildup, particulate debris, or a damaged plunger/diaphragm). Understanding the valve’s dual role - as an electrical actuator and a fluid sealing assembly – helps differentiate between an electrical fault (no click, no actuation) and a hydraulic fault (valve clicks but no flow or leaks when de-energized). Compatibility considerations are primarily mechanical and hydraulic: replacement valves such as the W10585391 are matched to inlet/outlet fittings, mounting points, and expected inlet pressure ranges on compatible Whirlpool platform refrigerators.
- No water to dispenser or ice maker – indicates open coil, lost supply voltage, clogged inlet, or failed internal seat; verify supply pressure and continuity at the valve connector.
- Intermittent dispensing or slow fill – suggests partial obstruction of the inlet screen or reduced water pressure; inspect and clean the filter screen and supply line.
- Continuous flow or drip when idle – points to a stuck plunger or worn seat allowing backflow; check for debris and perform a bench actuation test.
- audible humming or clicking without flow – coil receives voltage but the mechanical assembly fails to open; measure coil resistance and attempt controlled actuation to isolate electrical vs. mechanical failure.
| Item | Description |
|---|---|
| No water to dispenser or ice maker | confirm inlet pressure, check electrical continuity at the valve coil with a multimeter, and verify the control board is supplying the rated actuation voltage at the connector. |
| Continuous drip or uncontrolled flow | Inspect and remove debris from the inlet screen, inspect the plunger/seat for wear, and replace the valve if the seat cannot form a seal during a bench test. |
| Humming/clicking but no water | Measure coil resistance against manufacturer specification and perform a live actuation test; if coil is within spec but no flow occurs,the mechanical valve body is likely seized or the diaphragm is torn. |
Practical diagnostics combine electrical and hydraulic checks: start by confirming supply pressure and visually inspecting the inlet screen, then perform a resistance/continuity check on the coil and monitor for the valve’s audible response when the dispenser or ice-making cycle is activated. If the coil energizes and the valve does not open,bench-testing the assembly with the correct rated voltage (per the refrigerator’s service manual) will quickly separate an electrical control problem from a failed valve body; for field repairs,replacing with a matched part number such as W10585391 ensures correct fittings and expected performance characteristics for the model family. Record measured resistance values and inlet pressure during troubleshooting to support repeatable diagnostics and proper parts selection.
Compatibility, Replacement Considerations, Installation Procedure and Troubleshooting Diagnostics for W10585391
The W10585391 Whirlpool Refrigerator Valve is an electrically actuated water inlet valve that regulates water flow to the ice maker and dispenser. in practice this component mounts at the refrigerator chassis where the incoming water line connects to a screened inlet; internal solenoids open and close passages to route water to either the ice maker fill cup or the dispenser outlet. Compatibility is determined by valve body shape,inlet/outlet port locations and sizes,electrical connector type,and the refrigerator control board’s drive voltage – replacing with an identical OEM valve or a verified equivalent ensures correct hose routing,spade/plug alignment,and sealing surfaces without modifying the refrigerator cabinet or water plumbing.
Replacement and diagnostics focus on mechanical sealing, electrical actuation, and water supply conditions. For installation,shut off water and power,relieve system pressure,disconnect the supply and harness,swap the valve,and confirm leak-free connections before restoring water and power; use hand tools and new compression fittings or manufacturer-recommended tubing to avoid strain. Troubleshooting typically involves verifying water supply continuity, inspecting the inlet screen for debris, checking for visible leaks at the valve body, and using a multimeter to measure coil continuity and confirm the control board sends an actuation signal. Typical symptoms and quick checks are listed below to guide a systematic diagnosis.
- No water to dispenser or ice maker – check shutoff valve, inlet screen, and supply tubing for kinks or blockages.
- Weak flow – inspect pressure at the inlet and clear sediment from the valve screen or replace the valve if internal flow passages are clogged.
- Continuous water flow or leaking – examine valve seat and seals; replace valve when seats do not close under no-actuation conditions.
- Intermittent operation – verify harness connections and measure coil continuity and control voltage during a dispense or harvest cycle.

Q&A
What is the W10585391 valve and what does it do?
The W10585391 is an OEM Whirlpool refrigerator water inlet/solenoid valve assembly. It controls water flow from your home supply into the refrigerator for the ice maker and the water dispenser. The valve opens when the ice maker calls for fill or when you press the dispenser, and closes to stop water flow.
What symptoms indicate the W10585391 valve is failing?
Common symptoms include: no water to the dispenser or ice maker, slow or weak water flow, ice maker not filling, continuous leaking or dripping from the dispenser or into the ice bucket, and humming or clicking from the rear of the refrigerator. These symptoms can also be caused by low house water pressure, clogged inlet strainers, frozen supply lines, or control board issues, so diagnose carefully.
How do I test whether the valve is faulty?
Safety first: disconnect power and shut off the water supply before servicing. Visually inspect the inlet screen/strainer for debris and the valve for leaks. Use a multimeter to check each solenoid coil for continuity (you should see continuity; exact resistance varies by valve model). To test operation,restore power,have someone actuate the dispenser or ice maker,and measure for voltage at the valve connector (refer to the refrigerator wiring diagram for expected voltage – many models use line voltage,but confirm before testing).If the coil has continuity and receives the correct voltage but the valve does not open, the valve is defective.
where is the W10585391 valve located on the refrigerator?
The valve is typically mounted at the back lower-left or lower-right of the refrigerator, near the compressor and attached to the chassis. It is indeed connected to the incoming water line and has one or two outlet ports that feed the ice maker and dispenser.
How do I replace the W10585391 valve?
Turn off the refrigerator power and shut off the water supply. Move the fridge away from the wall and remove the rear access panel to expose the valve. Disconnect electrical connectors and carefully disconnect the water supply and outlet tubing (have a towel and bucket ready). Remove mounting screws and swap in the new valve (use any supplied gaskets or ferrules). Reconnect tubing and electrical connectors, turn the water back on, check for leaks, restore power, and test for proper filling. If the valve uses compression fittings, ensure they are tightened to prevent leaks.if unsure, hire a qualified technician.
Is the W10585391 compatible with my refrigerator model?
W10585391 is an OEM Whirlpool part used on many Whirlpool, Maytag, KitchenAid and some Kenmore refrigerators, but compatibility varies by model and production date. The only reliable way to confirm compatibility is to check the part number on your current valve or enter your refrigerator model number into Whirlpool’s parts lookup or a reputable parts supplier. Don’t rely on visual similarity alone.
Why does the valve hum or buzz but no water comes out?
Humming indicates the solenoid is being energized. If there’s no water flow, common causes are low or shut-off house water pressure, a clogged inlet strainer/screen, frozen supply tubing, a stuck internal valve seat, or a physically damaged valve. Check water supply and strainers first; if pressure and inlet screen are OK and the valve still doesn’t pass water while energized, the valve is usually the problem.
Can I clean the valve or inlet screen, and what water pressure is required?
Yes – many inlet valves have a removable mesh screen/strainer where the house line connects; debris can be rinsed or replaced. Always shut off the water first. Refrigerators typically require a minimum household water pressure (frequently enough around 20-40 psi recommended) for fast filling and proper dispenser operation; consult the refrigerator’s installation manual for the exact spec. If your pressure is too low, or if the screen is clogged, cleaning or correcting the supply pressure may restore operation without replacing the valve.
