218859701 Frigidaire Single Solenoid Water Valve â˘is âan electrically actuated, singleâcoil valve âassembly âdesigned toâ control the on/off flow of âpotable â¤water âinto a householdâ appliance.As a singleâsolenoid device it uses oneâ electromagnetic coil and âŁa movable plunger or diaphragm within a molded valve body to⤠open âagainst âinlet pressure when energized and âclose⣠to seal the supply when deâenergized; â¤the assembly typically includes⤠inlet/outlet fittings, a mounting flange, âand an âelectrical âconnector for the appliance â¤harness.
Inside an âappliance âthe â¤valve acts as the primary water admission device,⤠directly interfacing â¤with â˘the⢠external water supply line âand âŁthe âŁappliance control system. It is â¤indeed commonly found on appliances that require â˘controlled fills-such as â˘refrigerators with âŁiceâ makers and water dispensers, dishwashersand some laundry machines-where it governsâ timing and volume âof water delivered to downstream âŁcomponents. Functionally it interacts with â¤the âŁcontrol board âŁor timer (which provides the electrical â˘actuation signal), internalâ sensors or switches that confirm⤠fill statusand the plumbing⣠path âincluding filters âor⣠inlet screens; âproper operation depends⤠on adequateâ inlet pressure, intact⣠internal âsealsandâ a functioning solenoid coil.
This article will explain theâ valve’s operating principles and typical specifications, outline compatibility âand âfitmentâ considerations for service âreplacement, identify⣠common failure symptoms (such as no fill, continuous flow, âintermittent operationor external leakage),â and provide practical troubleshooting⢠and⢠diagnostic steps a technician or⢠informed appliance owner can use.⤠It will⣠also âcover replacement considerations such as verifying part numbers, â˘connector and fitting⣠types, basic safety â¤and isolation procedures before â¤serviceand postâreplacement checksâ to⣠confirm⤠leakâfree operation and correct⣠fill behaviour.

Functional Role and System Integration of the⢠Refrigerator Water Inlet Valve
The 218859701 Frigidaire Single Solenoid â¤Water âŁValve âis the electro-mechanical control that meters inlet water to the refrigerator’s dispenserâ andâ ice-making â¤subsystem. in normal operation â˘the⣠valve is normally closed; the refrigerator’s control board energizes the âŁsolenoid âcoil âto liftâ an internal⢠plunger or â˘deform a diaphragm,⤠opening⤠the orifice âŁand âallowingâ water to flow. Flow rate and fillâ volume are persistent by the valve’s orifice geometry and the household supply pressure, so replacement with the correct âpart preservesâ the original â˘metering characteristics. Commonâ failure modes seen in the âfieldâ include âsolenoid coil⣠failure (open or short), a sticking âplunger âor clogged â¤inlet screen, âandâ membrane/seat wear that results âŁin⢠leakage orâ incomplete â¤shuts; these â˘behaviors⤠explainâ symptoms such⤠as no-water dispense, continuous â˘drip into âthe ice mold,â or very slow fill⢠cycles.
- Functional features: single solenoid actuation, normally-closed âoperation, âintegral inlet screen/filterand âOEM-specific mounting and connection interface.
- Diagnostic â¤cues: â¤audible clickâ on coil âŁenergization, continuity or resistance reading across coil terminals, âvisible leakage atâ fittingsand erratic fill timing.
- Compatibility notes: electrical connector,coil voltage,and plumbing fittings must match the appliance harness and âwaterline; verify against the refrigerator service manual before replacement.

| Function | Meters water flow on energize; âcloses⣠to stop flowâ when â¤de-energized |
| Installation considerations | match electrical âconnector, coil specification, âand inlet/outlet fittings to âOEM requirements; ensure âinlet⣠screen isâ clean |
From aâ system-integration perspective, this valveâ interfaces directly with both theâ waterâ plumbingâ and the refrigerator’s control electronics, so â¤coordinated checks during⤠troubleshooting are necessary. Technicians âshould âconfirm proper âcoil voltage and connector â¤pinout,verify supply pressure⣠and inlet filter condition,and inspect mounting alignment and â˘tubing⣠orientation to avoid⤠kinks or stress⤠on fittings. In practice, replacing a failed valve with the âcorrect OEM part ârestores âthe⢠engineered orifice and sealing surfaces; though, addressing upstream debris, âlow âsupply pressureor a⢠faulty control board may âalso be⢠required to resolve recurring faults.â When fitting the replacement, ensure all electrical⣠and water connectionsâ are âsecure and that any in-line filters â¤or âpressure regulators âpresent inâ the system â¤are compatible⣠with the valve’s⣠flow characteristics.
How â¤the 218859701 Frigidaire⤠Single â˘Solenoid Waterâ Valve Operatesâ Within the âWaterâ Supplyâ and Control Circuit
The 218859701 Frigidaire Single Solenoid Water âValve is⤠a ânormally-closed electromechanical â¤valve that isolates the household water supply untilâ the âappliance control delivers an electrical drive signal. When theâ control boardâ energizes⤠the valve coil,⤠the magnetic⣠plunger lifts or displaces aâ seal or⣠diaphragm, opening the âflow path from the inlet â¤to the outlet and allowing water to pass to â¤the appliance fillâ circuit. The control system times or senses the duration of the open state to meter volume â(for example,filling an ice maker trayâ or a dispenser âŁreservoir),and returns â¤the valve to the closed position when the⣠coil is de-energized,preventing backflow and minimizing leak riskâ when âidle.
- normally âclosed: remains âsealed without power to⢠avoid unintended water⢠flow.
- Single solenoid operation: one electrical coil controls open/close⣠action.
- Integral strainer or inlet screen:â traps debris that âcan cause sticking or leaks.
- Standardâ inlet/outlet fittings and mounting points: verify mechanical compatibility âbefore replacement.
- Common â˘failure symptoms: no fill, continuous fill, slow flowor electrical open-circuit in the coil.
Compatibility is determinedâ by mechanical âŁfittings and⣠the âappliance’s âelectrical driveâ method; the valveâ must match the control voltage and connector style used byâ the appliance or be driven âŁthrough theâ appropriate relay. Practical troubleshootingâ includes checkingâ for continuity across the coil, confirming the⣠control board supplies theâ expected â¤drive signal during a âfill cycleand âŁinspecting the inlet screen âforâ clogging. In ârepairâ scenarios, replacing â¤the valve with⣠the correct part number âor â¤an approved equivalent restores normal operation; if intermittent operation â¤persists afterâ replacement,â verify⢠upstream water pressure, solenoid drive waveformand â˘any inline filters or pressure-sensing components that interact withâ theâ fill sequence.

Diagnostic Symptomsâ of âFailure: Water Flow Reduction, Leaksand Electrical Fault Indicators
The 218859701 Frigidaire Single âSolenoid Water Valve is an electromechanical inlet valve⣠that⤠controls water âŁdelivery to dispensers, ice makers,â and fill cycles â¤by âtranslating an electrical âcommand fromâ the applianceâ control⢠intoâ linear motion â¤of âa âŁplunger or diaphragm assembly. In⣠practice the valve is ânormally âclosed and opens âwhen âthe solenoid coil is energized, exposing a fixed orifice whose diameter and internal flow path determine âtheâ maximum flowâ rate; restricted flow can â˘result âŁfrom internal debris, a âdamaged diaphragm/poppetor âmismatchedâ replacement valves with different orificeâ sizes. Technicians should confirm⢠mechanical fit (port⢠size, mounting âorientation) and electrical âconnector âcompatibility before replacement âto ensure⤠the â˘valve behaves as â˘intended in the specific Frigidaire model.
Common⣠diagnostic indicators of⣠imminent⢠or partial failure include reduced flow rate at theâ dispenser âor ice tray, visible or internalâ leaking, â¤and electricalâ fault behaviors such as coilâ open-circuit or a coil â˘that⤠hums without â¤actuating the plunger. Diagnostic steps include verifying inlet âwater âpressure and screen/filterâ cleanliness, performing a continuity/resistance check on the solenoid coil,⣠observing for a â¤distinct click when the⤠control⣠commands the âvalve,⢠and isolating the valve from â˘the plumbing to confirm whether flow issuesâ persist. Practical examples:â a⢠slow-fillingâ ice tray ofen points to âan⢠obstructed or partially stuck valve,â while continuous dripping or pooling beneathâ the valve suggests a failed seat orâ diaphragm.
- Reduced flow âŁ-⢠weak⣠dispenserâ stream âor small ice cubesâ dueâ to âŁrestricted⤠orifice or partial plunger seizure.
- Leaks âŁ-⢠external water at fittings or internal bypassing when â˘valve should be closed,⣠indicating failedâ seat/diaphragm.
- Electrical fault â -⤠no continuity or⤠humming âwithout actuation,pointing to coil failure or mechanical binding.
- Intermittent⢠operation – âinconsistent fills that â˘may indicateâ thermal expansion issues,wiring faults,or a failing solenoid.

Replacement Considerations, Mounting Requirementsand âStepâbyâStep Installation⤠Procedures⣠for the Valve
The⢠218859701 Frigidaire Single Solenoid Water Valve⤠controls⣠water deliveryâ to the dispenser/ice-maker by⢠opening â˘a normallyâclosed âŁsolenoid when energized andâ allowing water to âpass âthrough its inlet/outlet ports. When âreplacing this âvalve, verify âmechanicalâ and electrical compatibility: match the part number âand the coil voltage stamped⤠on⢠the body, confirm inlet and⢠outlet tube diameters and⢠thread types, â˘and inspect the âvalve’s gasket and mounting⤠bracket arrangement. The âvalve’s behaviorâ is predictable-energize the coil and the plunger retracts to permit flow-so failures typically present as âno-fill, continuous fillorâ leaks; replacing the â˘valve alsoâ requiresâ attention toâ hose condition, â˘connector polarity (if applicable)and isolation from â¤vibrationâ to prevent fatigue ofâ fittings.
Follow â¤a deliberate procedure to avoid damageâ and leakage: isolateâ the âwater â¤supply and disconnect electrical power, relieve pressure in âthe water line, remove the âservice âaccess panel, âand observe manufacturer âtorque and sealing recommendations when installing the replacement. After installation, perform an electrical continuity â˘check of âthe coilâ and a functional test by cyclingâ the dispenser/ice-maker through a⤠fill cycle while monitoring for proper âvalve actuation and any â˘drips at âfittings. Practicalâ examples:⢠use a⤠compression sleeve⤠or new hose nutâ rather than reusing âa deformedâ fitting,and replaceâ Oârings if brittle; â¤if the refrigerator uses⢠a grounding â¤clip or keyed âconnector,seat it fully to avoid intermittent âoperation.
- Shut off water and âpower,â relieve âline â˘pressure,⤠remove access âpanel.
- Disconnect âelectrical connector, label wires if multiple circuits are present.
- Unscrew mounting screws/bracket, â¤remove⤠old valve and fittings (catch⢠residual âwater).
- Install new valve with supplied⢠gasket/Oâring, hand-start â˘fittings âthen torque to spec.
- Reconnect electricalâ connector, restore water â˘and power, check for leaks and verify â¤fill cycles.

Q&A
What appliances use the frigidaire⣠part 218859701 â˘single solenoid water âŁvalve?
218859701 â¤is â˘an OEM-style single-solenoid water⣠inlet valve âŁused âonâ certain⤠Frigidaire/Frigidaire-affiliated refrigerators, ice makers â¤or other household appliances that ârequire a single controlled cold-water inlet. Always confirm compatibilityâ by checking your appliance model number⣠against the part âlisting or the manufacturer’s parts diagram âbefore purchasing.
What are the âcommon symptoms âthat this water valve is âfailing?
Common symptoms⤠include noâ water⤠to the ice maker or dispenser, continuous leaking into theâ ice maker or dispenser even when â˘not calling for water, intermittent water flow, â˘or a âbuzzing/â humming ânoise⤠when⣠theâ valve should be closed. Failure can be⢠electrical (coil open) or mechanicalâ (stuck plunger, â¤worn seator debris).
How do I âtest the valve âŁtoâ determineâ if it is indeed bad?
First âdisconnectâ power to the appliance and turn off the water supply. Unplug âthe âvalve’s wiring âŁconnector⢠and use a multimeter to check for continuity across the solenoid coil-an open â¤circuit âindicates a failed coil. Youâ can also check that â˘the âŁvalve receives â˘the correct control voltage â¤during⤠aâ fill âŁcycle (consult the appliance wiring diagram for expected voltage). If the coil has continuity but the â¤valve still leaks âor â¤won’t open, the⢠internal seat⢠or plunger is likely stuck or damaged âand the valve âŁshould⣠be replaced.
Can the valve be âcleaned or âŁrebuilt instead of replaced?
Minor issues âcaused by⣠debris may sometimes be⤠resolved by⣠shutting off the⤠water, removing the valveand flushing it or â˘cleaning the âinlet screen. However,⤠most internalâ seal/plunger failures⤠and coil failures âare not practical to rebuild; in those⣠cases replacement ofâ the â˘entire âvalve assembly⢠is the recommended and more reliableâ solution.
What are the â¤steps to replace the 218859701 water valve safely?
Turn off the appliance power and the⤠water supply. Remove the access panel to reach the valve. Note â¤or photograph wire⤠and hose locations, disconnect âelectrical connectorsand disconnect the water lines (have towels/bucket⢠ready). Remove mounting screws and install theâ new valve in⢠the reverseâ order.⢠Reattach water âand power, âthen check carefullyâ for leaks and âŁproper operation. Always follow the â˘appliance⣠service manual and local electrical/plumbing codes.
Do â˘I need⢠to worry about water pressure â¤or fittings whenâ replacing theâ valve?
Yes. use the correct inlet/outlet⣠fitting âŁsizes and ensure⤠household water pressure is within the applianceâ manufacturer’sâ recommended range. Excessively âhigh⢠pressure can cause leaks or valve⢠failure; a pressure âregulator may beâ required. Also inspect or replace any inlet strainers/screens â˘to minimize âfuture debris-related failures.
What voltage/current does the âsolenoid⢠use and how âŁdo I âŁsafely bench-test a replacement?
Voltage and coil âspecifications â¤vary by appliance model. Many âŁU.S. household appliances use 120 VAC⢠coils, but some use lower voltages. Do ânot â˘apply mains voltage⤠to the coil unless you âhave confirmed âthe correct rating for âthat specific part and you have⤠proper safety equipment. For bench-testing, consult the service sheet â˘for the appliance to âconfirm âexpected control voltageâ and âŁfollow âsafe electrical testing practicesâ (orâ test âcontinuity only with a multimeter if you â¤are unsure).
Where âcan I âget a replacementand is aftermarket acceptable?
You can â¤obtainâ the partâ through⣠Frigidaire/authorized parts dealers, â¤appliance parts distributors,â orâ reputable⣠online retailers. OEM partsâ guarantee compatibility andâ original specifications;⤠many âaftermarketâ valves will function correctly if they are⤠specified as direct⤠replacements, but check reviews, return policiesand warranty â˘before buying. Keepâ the appliance model number handyâ to ensure correct fit âŁand valve orientation.
