W10585391 Whirlpool Refrigerator Valve is a⤠water inlet/solenoid valve assembly used in Whirlpool-brand refrigerators to control âthe flow of potable water into the appliance’s ice maker and dispenser systems. The component is an⤠electrically actuated âvalve âwiht one or more solenoids âŁand internal diaphragms or seats that open and close under command from the refrigerator’s control electronics to permit or halt water flow.
Inside the appliance, the W10585391 valve interfaces between the household water â¤supply and the refrigerator’s internal plumbing, typically feeding both the â¤ice maker fill tube⣠and the dispenser water line. It âinteracts with the water filter, supply tubing, ice maker fill mechanism and the refrigerator control board or microcontroller that provides the actuation signal. Proper operation depends on adequate inlet pressure, a clean filter and âintact valve seals; conversely, debris, pressure loss or electrical âfaults at the âvalve can cause no-fill, slow-fill,⤠leaking or intermittent âoperation that affects ice production and dispensing functions.

Function and Role of the Refrigerator Water Inlet Valve: Flow Control, sealingand Electricalâ Interface
W10585391 Whirlpoolâ Refrigerator Valve is a solenoidâactuated water inlet valve that controls delivery of potable water to the ice maker and dispenser circuits. The valve uses a plunger and elastomer diaphragm to provide positive shutoff against household water pressure and opens only when the refrigerator control board energizes the coil. Functionally, the valve performs three roles: flow metering for timed fills, hydraulic sealing to prevent â¤leaks when idleand an electrical interface âthat âŁtranslates board commands into mechanical motion. Fit and compatibility depend on port size,⣠mounting flangeand connector pinout,⤠so⣠installers should verify these physical details against the â˘appliance before replacing the â¤assembly.
From a diagnostic and operational viewpoint, the valve behaves as a simple electromechanical actuator: coil continuity indicates the electrical portion is intactand observed actuation under working water pressure confirms hydraulic function. Common failure modes are stuck or torn diaphragms that cause leakage,clogged inlets that reduce flow,and coil⤠failures that prevent opening. Technicians typically check coil resistance with aâ multimeter, inspect the inlet screen for debrisand verify timed fill durations from the control board; when parts⢠fail, full assembly replacement is standard practice because the molded⢠body and integrated ports are not easily serviced in the field.
- Primary functions: flow control, positive sealing, electrical actuation.
- Common diagnostics: coil âcontinuity, inlet â¤screen inspection, valve activation under pressure.
- Compatibility checks: inlet/outlet diameter, âŁmounting tabs, â¤electrical connector pinout.

How the W10585391 Whirlpool âRefrigerator Valve Operates within the âWater and Ice Dispensing System
The W10585391 Whirlpool Refrigerator Valve is the⤠electrically actuated component âthat controls water delivery to the ice maker and the door dispenser. â˘Internally it uses one or more solenoid-drivenâ poppets or diaphragms to open a⢠flow path from the household supply to the refrigerator plumbing when the control⢠board requests a fill cycle or a dispense action. Depending on the refrigerator design, the valve may contain⤠multiple ports and⢠separate âsolenoids to isolate the ice makerâ feed from the door dispenser; the control⣠board energizes the appropriate coil for a timed interval to deliver â˘a measured volume of water. â¤Technicians should verify the mechanical mounting, hose fitting sizesand connector⣠style when confirming compatibility with âa particular Whirlpool model or when replacing the âunit in the field.
In operation the valve behaves as an on/off metering device:â a âŁclean, responsive â˘coil produces a quick actuation and the internal seat/diaphragm provides shutoff againstâ inlet âpressure when de-energized. Typical failure modes include stuck-open seats (resulting in leaks or continuous drips), â˘clogged or â˘hardened diaphragms (reduced âŁflow)and coil faults (no actuation). For practical troubleshooting, check for visible leaks at the valve, confirm the control board is sending an actuation signaland verify coil continuity with a meter; replacing the valve is the common remedy when the diaphragm or internal seals are compromised. The valve is an OEM-form component intended to match the refrigerator’s plumbing âand electrical â˘interfaces, so cross-referencing the part number before installation avoidsâ fitment and performance issues.
- Common symptoms: no water flow,weak flow,continuous dripping,or ice maker not filling.
- functional features: solenoid actuation, internal seating/diaphragm, âmultiple ports âon multi-feed valves.
- Field checks:⣠visual leak inspection, electrical continuity of the coil, comparison of connectors and port sizes for compatibility.
| Item | Description |
|---|---|
| Function | Electrically controlled on/off valve âthat routes household water âŁto ice maker âand/or dispenser. |
| Actuation | Control-board driven solenoid that opens a diaphragm or seat for a timed water delivery. |
| Compatibility | OEM replacement matching mounting, hose fittingsand electrical connector; verify part number before â¤install. |
Common Failure Symptoms and Diagnostic Indicators for Inlet Valve âMalfunction
The W10585391 Whirlpool Refrigerator Valve is the âsolenoid-actuated inlet valve that meters potable water into the ice maker and door dispenser. Typical failure modes are mechanical (diaphragm or seat wear), hydraulic (clogged inlet screen or low supply pressure), âŁand electrical â(open or shorted coil, intermittent connector).Because this valveâ interfaces directly with⢠the water line, symptoms can include no water delivery, slow⤠fill, continuous trickle from the âŁdispenser âor iceâ makeror external leaking at the valve body or fittings; compatibility âconcerns for replacement are limited â˘to matching theâ inlet/outletâ fittings, mounting pointsand the valve’s electrical connector standard for the refrigerator model.
- No water from dispenser or ice maker despite a good supply âline.
- Intermittent dispensing or occasional clicking without flow.
- Continuous water flow until supply is shut off.
- Visible leak at valve body, fittingsor internal pooling in the cabinet.
- Reduced flow that is not solved by replacing the water filter.
Diagnostic steps focus on isolating hydraulic from electrical causes:⣠visually inspect⢠for leaks and debris at the inletâ screen, verify inlet water pressure and filter condition, check the valve’s coil for continuity with a multimeterand confirm the control board âis issuing an activation signal at the harness while⢠a dispense or âice-fillâ cycle is commanded. A practical example: a valve that clicks but does not pass water often has a ruptured diaphragm or clogged orifice – the coil energizes correctly but the mechanical seal fails. If continuity isâ absent âorâ the valve remains â¤open with no activation signal, replacement is appropriate; ensure the replacement part matches the original valve’s fittings and âconnector style before installing.
| Item | description |
|---|---|
| Coil continuity | Use a multimeter to verify the coil is not open; consult the service manualâ for expected resistance range. |
| Activation signal | Measure harness voltage during dispense/ice-fill to⤠confirm the control board is commanding the valve. |
| Hydraulic inspection | Check inlet screen, fittingsand supply pressure; debris or low pressure can mimic valve failure. |
Compatibility, Replacement Considerationsand StepâbyâStep Installation for Supported Whirlpool Models
The W10585391 Whirlpool Refrigerator Valve is a âsolenoid-actuated water inlet âassembly that meters household water intoâ the dispenser and icemaker circuits. It âfunctions as an electrically controlled valve that opens when a control board⣠orâ dispenser⤠switch applies âvoltage⣠to the coil and⣠closes when the coil is de-energized, â¤soâ correct electrical continuity and coil â˘voltage are essential for proper operation. Compatibility dependsâ on the valve’s port configuration,mounting bracket orientation,and electrical connector; many Whirlpool and affiliated modelsâ use the same basic assembly but require verification of inlet/outlet port sizes,number âof⤠valve⣠outlets,and harness type before replacement. Common fault signatures for valve issues include no dispense or no ice production, weak flow, continuous run-on of waterand visible leaks at the valve body âor tubingâ connections, which can be diagnosed by measuring coil resistance and verifying mains voltage at the connector during a dispense or fill command.
For replacement and⣠installation,verify âthe OEM part number and compare the physical valve (port count,bracket,connector) âto the old unit; if thay differ,do ânot assume interchangeability. Prior to disassembly, shut off water and power to prevent flooding and electrical hazardand relieve pressure in the feed line by actuating the dispenser or opening a downstream valve. During installation use â¤new compression fittingsâ or push-fit tubing rated for potable water, hand-tighten fittings then follow manufacturer torque guidance where specifiedand avoid âover-stressing plastic ports. After reassembly, restore water and power, operate a manual⢠fill cycle and inspect all joints for leaks for several minutes; âconfirm âŁexpected fill volume and that theâ control commands open and close⢠the valve reliably before returning âthe appliance to service.
- Basic replacement steps: shut off water/power; remove access panel; disconnect electrical connector and tubing; âunfasten old valve; install â¤new valve; reconnect tubing and connector; restore water/power; test for leaks and proper fill.
| Item | Description |
|---|---|
| Electrical | Match coil voltage and connector pin count to the existing harness; measure coil resistance if uncertain. |
| Water connections | Confirm inlet/outlet port sizes and use compatible compression or push-fit fittings for potable water lines. |
| Diagnostics | Symptoms: no flow, continuous flow, slow flowor visible leaks; check voltage during command and coil resistance offline. |
Q&A
What is the W10585391 valve and what does it do in my Whirlpool refrigerator?
The W10585391 is the water inlet (or waterâ fill) valve assembly used on many Whirlpool-family refrigerators. It controls water flow from your household supply to âthe âice maker and/or dispenser. The valve contains electric âŁsolenoids that open and close the water passages when the ice maker or dispenser calls for water.
What are âthe common âsymptoms that the W10585391â valve is failing?
Common signs include: no water to the ice maker âŁor dispenser, â˘slow or reduced waterâ flow, continuous dripping or running water into the ice maker or dispenser, water leaks at the valve areaor ice maker notâ fillingâ properly. Some failures⢠are caused by clogged â˘inlet âscreens, âother times â˘the internal diaphragm or solenoids fail electrically.
How can Iâ test the W10585391 valve to see if it is bad?
First turn off powerâ and water.Visually inspect the valve and inlet screen for debris.With⣠the refrigerator unplugged, use a multimeter to check each solenoid coil for continuity (typical solenoids are low ohms; âcompare to service manual specs). You can also test function by restoring power briefly and activating the âdispenser or iceâ maker while watching the valve (only if you âare comfortable and take â¤safety precautions). If solenoids â˘have no continuity or the valve does not open when energized, the valve is faulty. If unsure, contact a qualified technician-working with live mains power can âbe perilous.
Is the W10585391 compatible with my refrigerator model?
W10585391 is an OEM Whirlpool part used on many Whirlpool, Maytag, KitchenAid and Amana âŁmodels, but not all.â Compatibility depends on your exact appliance model number. Alwaysâ verify compatibility by entering your refrigerator model number where you buy parts or by checking the manufacturer’s parts list before purchasing.
How difficult is it toâ replace the W10585391⤠andâ what tools â¤are needed?
Replacement difficulty is moderate and within scope for âŁa handy homeowner. typical tools: screwdriver or nut driver set, pliers, bucket/towels for waterand possiblyâ a multimeter. Steps in brief: shut off water and power, remove the lower access panel, disconnect electrical connectors and water lines from the old valve (catch water), install the new valve⣠with correct gaskets or ferrules, reconnect lines and wiring, turn water âŁand power back on and check for leaks and âoperation. If you’re not⣠comfortable with plumbing orâ electrical work,hire a technician.
How much water âpressure does the W10585391 need to operate correctly?
most refrigerator inlet valves require household water pressureâ within a typical range (commonly around 20-120 psi supply, with best performance above 30-40 psi for good fill rates). Very low pressure can cause slow filling; very high pressure can stress connections. If pressure is low, check your homeâ shutoff valve, filtersor supply tubing. refer to your refrigerator’s specifications for exact âpressure recommendations.
Will â¤cleaning the â¤inlet screenâ fix water flow problems or⤠do I need to replace the valve?
Sometimes debris trapped in the inlet screen or sediment in the valve causes reduced flow and cleaning the screen can restore normal operation.However, if⤠the valve’s internal diaphragm, solenoidorâ seals are worn⤠or if you have intermittent electrical operation, cleaning won’t help and the valve should be replaced. Inspect the screen when⢠you âremove the â¤valve; if it’s heavily corroded or⢠damaged, replace the valve assembly.
Any tips to avoid leaks or problems after installing a new W10585391?
Turn the water supply on slowly and check all connections for leaks. replace any old ferrules, grommetsor washers when reconnecting water lines. Make sure electrical connectors are fully seated. Confirm the refrigerator is level â˘so the ice maker fills properly. After installation, run a few dispense/ice cycles and visually inspect the valve and supply lines for leaks. If you detect a leak at the valve fittings, tighten fittings carefully-do not overtighten plastic fittings-or re-seat the tubing with a new ferrule if ârequired.
