218859701 Frigidaire Single Solenoid Water Valve isâ anâ electromechanical inlet valve used to control â¤the flowâ of potable water into an âappliance. âAs a single-solenoid design, it receives an electrical pulse from â˘the appliance control system âto open adn allow water âto passâ through anâ inlet port⢠to downstream components; when de-energized it returns to the closed state âto stop flow. Technically,the component combines⤠a solenoid⣠coil,plunger/armature,valve⢠seat and sealing elements in âa âŁcompact assembly sized to matchâ common appliance water lines and mounting points.
Inside an appliance the valve acts âas theâ primary water delivery âgate and interfacesâ directly with the household water supply, internal plumbing (tubing⢠and fittings), water âfilters, â˘ice maker or dispenser assembliesand the appliance control board that governs fill timing âand safety interlocks. It responds to low-voltage control signalsand its performance is affected by inlet pressure, particulate contamination, seal condition⢠and electrical continuity; failures or degraded operation âŁcan manifest⤠as⤠no-water, slow fills, continuous flowor leaks that impact ice production, dispensing accuracy and appliance safety⣠systems.
In the following article readers will find a technical overview of the valve’s function and typical electrical and plumbing compatibility considerations, common failure â˘symptomsâ and⤠diagnostic âchecks â˘(including electrical measurement âand leak/flow tests), practical⣠troubleshooting sequences to isolate electrical âversus mechanicalâ faultsand⣠replacement considerations such as part fit, mounting orientation, âŁsealing and safe water shut-off procedure. âthe content is aimed â¤at technicians, engineers and informed appliance owners who needâ practical, repair-focused⢠facts ratherâ than marketing âdetail.

Function and âRoleâ of the Single-Solenoid Water Valve in Frigidaire Appliance Water Delivery
The 218859701 Frigidaire Single solenoid Water Valve is an electromechanical shutoff device that controls⣠theâ flow of âwater toâ the icemaker and dispenser. The valve âuses a single solenoid âtoâ move an internal plunger against an elastomer seat; the default position is normally closedand the valve opens only when the refrigerator control board applies a voltageâ to the coil. In âŁpractice this component receives on/off commands from the appliance’s control â˘circuitry⣠and provides an electrically controlled hydraulic interface between the⣠household water â¤supply and the internal water pathways, so correct electrical connector orientation, mounting positionand hose connections are essential for proper operationâ and fitment.
- Operation: single-solenoid, âŁsolenoid-actuated poppet âor plunger valve that opens when energized.
- Interfaces: typically two-wire electrical connection and standard â˘barbed inlet/outlet for water âŁhose attachment; verifyâ connector typeâ before replacement.
- Behavioral âsigns of failure: no water to âdispenser/icemaker, continuousâ fillingor visible leaks; mechanical blockage or coil failure are common causes.
- Service considerations: âcheck coil continuity and control âvoltage, inspect inlet screen⤠for⤠debrisand confirm water âpressure and hose routing during diagnostics.
Technicians shouldâ verify model compatibility and electrical specifications against the refrigerator’s service literature before installing âŁa replacement. In many⢠field repairs âthe symptom pattern helps isolate theâ valve: an audible â¤click âwith no flow suggests âa downstream⤠plumbing or pressure âissue, âwhile no click and no flow suggests a failed coil or⢠missing control voltage. â˘Replacements labeled 218859701 frigidaire Single âSolenoid Water Valveâ are âoften âŁdirect-fit OEM parts for specific Frigidaire and affiliated models, but always match the partâ number, connector styleand mountingâ footprint to avoid cross-compatibility issues.

How the 218859701 Frigidaire Single Solenoid âWater Valve Works Inside the Appliance
The 218859701⢠frigidaire Singleâ Solenoid Water Valve â˘is an electromechanicalâ inlet valve that controls one water path insideâ an appliance. Energizing the solenoid coil pulls âa âplunger or lifts a diaphragm to open the water passage; when the coil â¤isâ deâenergized âŁthe âvalve returns to its normally âŁclosed state to stop flow. The valve is intended â¤to be driven by the appliance â¤control board, whichâ supplies the appropriate coil voltage and timing for fills (such as to âan âice maker,⤠dispenser,â or a single fill circuit). Physically the component â¤providesâ one inlet and one outlet⢠port, a builtâin strainer or screen on the inlet to catch debrisand âŁa molded electrical âconnector âŁsized âto the OEM harness for proper fit and orientation.
Understanding the valve’s behavior helps separate⣠electrical faults from hydraulic problems. electrical failures show up as an open coil (no continuity) or intermittent operation â˘(coil heating or partial short), while hydraulic failuresâ are âdueâ to cloggedâ screens, low inlet pressureor worn internal â¤sealsâ that causeâ slow fill or leaking.⣠In practice, technicians verify coil continuity with a multimeter,â confirm correct voltage at the⤠connector during a commanded â¤fill, inspect and clean the inlet⢠screenand measureâ inlet pressure beforeâ replacing the valve. Matching the OEM part number andâ connector orientation minimizes⤠installation errors and â˘ensures the valve’sâ seat⤠and mounting align âwithâ the appliance’s water âchanneling.
- Key âfeatures: single inlet/outlet, solenoid-actuated⢠plunger or diaphragm, molded electrical connector, inlet debris screen.
- Common â˘symptoms of failure: no water, continuous flow, humming without flow, âslow fillor leakage.
- Basic diagnostics: check coil continuity, verify control-board voltageâ during cycle, âinspect/clean inlet screen, measure water pressure.
- Replacement note: use the â¤exact OEM part number or âverifiedâ cross-reference⢠to⤠ensure⢠proper electrical and mechanical âcompatibility.

Common Failure Symptoms âand Diagnostic Indicators for the Solenoid Water Valve
The 218859701 Frigidaire âSingle Solenoid Water Valve is an electromechanical, normally-closed valve that controls the supply of potableâ water âto refrigerator⣠functions such as the ice maker and dispenser. When the control board energizes the solenoid,â aâ plunger lifts a seal⤠to allow water to flow; âwhen de-energized the âspring forces the â˘seal closed. Technicians should note the valve’s mounting orientation, inlet/outlet port sizes and electrical connector type to confirm compatibility during replacement-matching electrical ratings and physical fittings prevents misapplication and reduces the risk of premature failure.
Common failure modesâ produceâ distinctiveâ operational andâ measurable indicators that guide diagnosis.â A loud or âweak click with no water flow often indicates a stuck spool, debris-clogged seator failed diaphragm; a continuous drip or⢠slowâ fill typically points to a failed seal or partial obstruction. To âisolate electrical from hydraulic faults,⣠measure continuity and coil resistance⣠with the circuit de-energized, then verify the âcorrect actuation voltage at âthe connector while a dispense â¤or harvest cycle is commanded. Practical troubleshooting also includes checking inlet water pressure and filters-low âpressure or a clogged line can âmimic valve âfailure even⤠when the solenoid â˘and coil are within specification.
- No water âŁdispense⤠despite audible â¤click – check coil voltage and inlet pressure.
- Intermittent fills or erraticâ ice cycles⣠– inspect for â¤debris, partial spool⣠movementor failing⣠diaphragm.
- Constant âŁflow or leaking at the outlet – likely internal seal failure requiringâ valve⢠replacement.
- No click andâ no continuity -⤠electrical coil open or connector/wiring fault.
| item | Description |
|---|---|
| Coil resistance | Measure with meter; expect continuity. Compare to manufacturer spec (typical solenoid âcoils range from hundreds to low kilo-ohms). |
| Actuation â¤signal | Verify control board supplies rated voltage during demand (many refrigerators use âline-level AC; â˘confirm model specification before testing live). |
| Hydraulic⤠checks | Confirm inlet pressure, downstream⤠flow â¤pathand that filters/screens âŁare free of debris; trapped⢠particulate commonly prevents full opening. |
Compatibility,⤠Replacement Considerationsand âŁInstallation Requirements for 218859701
The 218859701 Frigidaire Single Solenoid Water Valve is a normally-closed, direct-acting valve used to regulate water flow into an appliance âcircuit (such⢠as, a dispenser or ice-maker fill). When the control board applies the correct coil voltage, the solenoid lifts an internal plunger or diaphragm allowing water to pass; removing power â˘closes theâ valve and isolates⤠theâ supply. Compatibility depends on matching theâ electrical coil specification, the number ofâ solenoids (singleâ vs. dual), â˘inlet/outlet connection types and sizes, â˘and the mounting â¤footprint. Technicians should confirm the OEM part number or â¤an approved cross-reference and inspect the valve label for coil voltage and⢠flow â˘direction before⣠installing a replacement.
- Verify coil voltage â¤and numberâ of solenoids to â˘match the applianceâ control signal.
- Confirm inlet/outlet fitting type and size (compression, â¤push-fitor threaded) and bracket/mounting alignment.
- Check electricalâ connector âstyle (spade terminals vs. harness) and plan for any adapter harnesses if necessary.
- Inspect for an â˘internal debris screen and âmatch rated operating⢠pressure/flow characteristics to avoid underfilling âor leaks.
- Test coil continuity and physical operation â(energize briefly while water is off) before final reassembly.
| Item | Description |
|---|---|
| Electrical | Match coil voltage and connector; measure continuity and compare to valve/service documentation. |
| Hydraulic | Confirm inlet/outlet fittings, presence of âdebris screenand that household water pressure falls within the âvalve rating. |
| Service Tip | Always shut⤠off water⤠and power, relieve pressureand replace any O-rings/gaskets removed â¤during replacement. |
Practical installation âŁrequires isolating water⣠and power, relieving line pressure, âŁand noting orientation so flow arrows âŁon the valve align with plumbing. Ifâ the valve is noisy,â fails to openor leaks, isolate causes by checking âŁelectrical continuity at the coil, âenergizingâ the valve brieflyâ while the âinlet⢠is capped to⢠observe plunger movementand examining the inlet screen for sediment.â Use proper compression or push-fit assembly practices for fittings, avoid over-tightening âfasteners that can distort the valve bodyand replace the valve if the diaphragm or plunger shows corrosionâ orâ scoring; retaining the original⤠mounting arrangement and electrical harness greatly reduces the â˘chance of installation-related failures.
Q&A
What is the 218859701 Frigidaire Single Solenoid Water Valve and what does it do?
The 218859701 is a refrigerator inlet water valve that uses a single solenoid â¤to control water flow. It opens â¤and closes the water supply when the refrigerator calls for water (for the dispenser or icemaker). It⢠is an electromechanical valve â˘that responds to⣠a low-voltage⣠control signal from â¤the refrigerator’s control board⢠or âuser interface.
How can I verify this valve is the correct⣠part for my refrigerator?
Check your â˘refrigerator model and serial number⢠(usuallyâ on a sticker inside⢠the cabinet or behind a kickplate) and compare it with the⢠part compatibility lists âŁon the manufacturer or authorizedâ parts dealer site.Also confirm the physical mounting, number âand size of ports, electrical connector type,⤠and label â¤information on⤠the valve itself. âŁWhenâ in doubt, match the OEM part number (218859701) âŁto the appliance model.
What are common symptoms of⢠a failing water valve?
Typical symptoms include: no water or very low water flow from the dispenser or icemaker,a valve thatâ stays open causing continuous flow or dripping,intermittent flow or⤠very slow fill times,and sometimes a buzzing or clicking noise â¤when the valve should be closed. Visible â˘leaks around the valve â¤or fittings are âalso a signâ of failure.
How do I test the valve to determine if it’s bad?
First, unplug the refrigerator â¤and shut off the water supply. Visually â˘inspect for leaks and damaged wiring. For an⣠electrical test, disconnect the valve’s â¤connector and measure coil continuity with a⢠multimeter – a functioning coil âwill show low resistance⣠(not infinite). You can âŁalso apply the correct control voltage briefly (only if you know the voltage âŁand are⢠experienced) to see if the âsolenoid⢠actuates; âor else âlisten for a click when the⢠refrigerator requests water. If the coil is open,or âŁthe âŁvalve âdoes not⣠openâ when energized⢠underâ safe conditions,replace⢠it. Always follow safety procedures.
Can I replace the⢠218859701 valve myselfand what precautions should I take?
Yes, a competent DIYer or technicianâ can replace it.Always disconnect power â¤to the refrigerator â¤andâ shutâ off â¤the water supply before beginning. Relieveâ pressure in theâ water line by dispensing water or loosening a fitting slightly. Note the orientation and connections (electrical plug and water lines) before removingâ the old valve. Install the new valve,â tighten fittings hand-tight plus⤠a small additional turn (avoid overtightening), â˘restore water and powerand check for leaks and properâ operation.
What are the typical electrical and⤠plumbing connections âfor this type ofâ valve?
Connections vary by model, but⢠single-solenoid refrigerator inlet âvalves commonly use a⣠two-wire electrical connector from the control⢠board and standard refrigerator water line fittings (often 1/4″ or 3/8″ compression tubing). The valve label or parts sheetâ will show the exact inlet/outlet sizes and the ârequired coil voltage. If⤠you⢠don’t have the label, verifyâ with the â˘appliance⤠model documentation beforeâ installing.
Why would the âvalve let water run continuouslyâ or drip â¤even when the dispenser âŁis off?
Continuous flow or dripping usually indicates â˘that the valve is ânot sealing properly â- caused by a failed solenoid, internal⢠debris or mineral buildupor a damagedâ valve seat. incorrect inlet pressure or a stuck actuator can âŁalso causeâ the problem. Inspect and clean inlet screens if accessible; if the valve does not âseal after â˘cleaning, replacement is typically â¤required.
