218859701 Frigidaire Single Solenoid Water Valve is an electrically actuated inlet valve used to control the flow of water into major household appliances. As a single-solenoid, normally-closed valve assembly, it opens when energized by the appliance control circuitry to allow water to pass through its inlet and outlet ports and closes when the coil is de-energized to stop flow. The component typically includes a solenoid coil, a valve body wiht inlet/outlet fittings, and an internal sealing mechanism or diaphragm to regulate water passage.
Inside an appliance the valve serves as the primary interface between the building water supply and internal water-using subsystems such as ice makers, water dispensers, or wash cycles. It interacts directly with the appliance’s control board, user controls or sensors that call for water, and the external plumbing and filtration elements upstream of the valve. Proper operation depends on correct electrical actuation, sufficient inlet water pressure, and a free, debris-free flow path through inlet screens and internal passages.
In this article you will find a technical overview of the valve’s function and construction, guidance on verifying compatibility and physical fit, common failure symptoms to watch for (no water delivery, continuous filling, or external leaks), practical troubleshooting checks (visual inspection, inlet screen cleaning, electrical continuity and applied voltage checks at the connector, and pressure considerations), and replacement considerations such as correct part identification, safe isolation of the water supply, proper mounting and connector mating, and post-replacement testing to confirm leak-free operation and correct electrical control.

Function and Role of the Water Inlet Solenoid in Frigidaire Appliances
The 218859701 frigidaire Single Solenoid Water Valve is an electromechanical control that regulates the appliance’s incoming water by using an energized coil to lift a plunger or deform a diaphragm, allowing water to pass through a single inlet port.In typical operation the valve remains normally closed and opens only when the appliance’s control board supplies the correct electrical signal; this direct on/off behavior makes it suitable for precise water metering for ice makers, dispensers, and fill cycles. the valve’s performance is steadfast by coil integrity, sealing surfaces, and inlet filtration-sediment on the inlet screen or a ruptured diaphragm will alter flow characteristics and can mimic electrical failures even when the coil measures within nominal resistance ranges.
Technicians should evaluate both electrical and hydraulic compatibility when diagnosing or replacing this part: verify the valve’s electrical rating and connector type against the appliance wiring harness,confirm inlet/outlet fitting sizes and mounting footprint,and follow the appliance schematic for activation tests. Common failure modes are no-fill (open-circuit coil, clogged screen), continuous-fill (sticking plunger or failed seal), and intermittent flow (partial obstruction or marginal coil insulation). Practical diagnostics include measuring coil resistance with a multimeter, listening for the audible actuation click during a commanded cycle, briefly energizing the valve under controlled conditions, and inspecting the inlet filter for debris before replacing the assembly with a component that matches the original specifications and mounting features.
- Rapid checks: coil continuity, audible click on activation, inlet screen cleanliness, and supply pressure.
- Installation notes: match electrical rating and connector type, verify port size and sealing surfaces, tighten fittings to specified torque to prevent leaks.
- Failure indicators: no water, continuous fill, or erratic intermittent fills under normal conditions.

How the 218859701 Frigidaire single Solenoid Water Valve Works Inside the Appliance
The 218859701 Frigidaire Single Solenoid Water Valve is an electromechanical component that regulates water delivery inside refrigerators, supplying the ice maker and dispenser on command from the appliance control board. Internally the valve uses a single electromagnetic coil to move a plunger or poppet against a seat and diaphragm; in the de-energized state the valve remains normally closed, preventing flow. when the control board applies the rated coil voltage the generated magnetic field lifts the plunger, opening the orifice and allowing inlet water to pass to the outlet; flow rate and on/off responsiveness are influenced by the valve orifice size and incoming water pressure, so correct plumbing and matching electrical connections are required for proper operation and compatibility with Frigidaire systems.
Behavioral characteristics and practical troubleshooting follow predictable mechanical and electrical patterns: the valve responds to short timed energizations from ice-making or dispensing cycles, produces a distinct click when actuated, and relies on a clean inlet screen to seal and operate reliably. Common failure modes include coil open or short, debris-clogged seats that prevent sealing (resulting in slow leaks), and plunger sticking that can leave the valve partially open or closed. Technicians typically verify coil continuity with a multimeter, confirm supply voltage from the control board, isolate the water line at the appliance shutoff, and inspect the inlet screen before replacing the assembly; if replacement is required, using the matching 218859701 Frigidaire Single Solenoid Water Valve or a part with identical electrical and mechanical specifications ensures proper fit and function.
- Key functional trait: single-coil, electromagnetically actuated, normally closed valve.
- Performance depends on inlet pressure, orifice size, and clean inlet screening.
- Troubleshooting steps: listen for click, check coil continuity, inspect inlet screen and plumbing isolation.
- Symptoms of failure: no water flow, continuous leaking, or intermittent operation.

Common Failure Symptoms and Diagnostic Indicators of the Single Solenoid Water Valve
The 218859701 Frigidaire Single Solenoid Water Valve is a normally-closed inlet valve that opens when the appliance control applies power to the solenoid, allowing pressurized water into the ice maker or dispenser. In normal operation the coil lifts a plunger or pin against a seat; compatibility for replacement depends on matching the mounting footprint, inlet/outlet fitting size, and electrical connector style. When the valve functions correctly it responds quickly to brief control pulses and seals tightly when de‑energized; common field failures change that behavior into partial flow, constant dripping, no flow, or intermittent operation caused by worn seals, debris in the integral strainer, or loss of coil continuity.
Technicians diagnose the valve by combining visual inspection with electrical and functional checks: look for external leaks, clogged screens, or damaged quick‑connect fittings; verify the presence of control voltage at the connector during a fill cycle with a meter; and confirm coil continuity to rule out an open winding. Practical examples include an ice maker that never fills (possible stuck‑closed or no control voltage), a dispenser that drips between uses (worn seat or debris), or a valve that hums without opening (insufficient inlet pressure or mechanically sticking plunger). Addressing replacement requires matching the 218859701 valve’s connector and inlet size and confirming that the control board is supplying the expected actuation signal before installing a new unit.
- No water to ice maker or dispenser - check for control voltage during call for fill and verify coil continuity.
- Continuous drip or slow fill – inspect the strainer and valve seat for debris or partial seal failure.
- Humming or clicking without flow – confirm inlet pressure and that the plunger moves freely; humming with no movement suggests mechanical binding or valve fatigue.
- Intermittent operation - examine wiring/connector integrity and test for intermittent voltage from the control board.
| Item | Description |
|---|---|
| Coil continuity | Use a multimeter to confirm the coil is not open; an open circuit indicates a failed solenoid. |
| Control voltage | Measure voltage at the valve connector during a fill command to distinguish electrical control issues from valve faults. |
| Strainer/screen | Remove any inlet debris or mineral buildup that restricts flow or prevents the seat from sealing. |
| Mechanical movement | With power removed, check plunger movement manually to detect binding or corrosion preventing proper operation. |
Replacement Considerations and Step‑by‑Step Installation for the 218859701 Frigidaire Single Solenoid Water Valve
The 218859701 Frigidaire Single Solenoid Water Valve is a single‑acting electromechanical valve that controls water admission to the appliance by opening its port when the solenoid coil is energized and closing under spring pressure when de‑energized. Technicians should verify coil voltage, connector style, and inlet/outlet fitting sizes on the existing valve before ordering a replacement; mismatched coil voltage or connector polarity can cause no‑actuation or coil failure. Common failure modes are internal seat wear (leading to slow leaks), a stuck plunger (valve stays open or fails to open), and coil burnout. Inspect the valve’s built‑in screen/strainer and mounting orientation during diagnosis – a blocked screen or incorrect mounting can mimic electrical failure even when the solenoid and wiring are functional.
Replacement is straightforward with basic hand tools but requires deliberate handling to avoid leaks or electrical faults. Isolate electrical power and shut off the water supply, drain residual pressure, and label electrical connectors before disconnecting. When installing the new valve, confirm the inlet/outlet hose routing, reuse or replace sealing washers as required, and torque fittings to avoid distortion of plastic bodies. After reassembly, apply power and run a controlled fill cycle while checking for leaks at the valve body, hose connections, and solenoid coil area; also measure coil current to confirm proper operation rather than relying on audible clicks alone.
- Shut off power and water supply; relieve pressure in the system.
- Document and disconnect electrical connectors; remove mounting screws and hoses.
- Inspect and clean or replace screens/filters before installing the new valve.
- Match coil voltage and connector type, install new valve, secure fittings, and restore water.
- Power the appliance, run a test fill, and inspect for leaks and correct fill timing.

Q&A
What is the Frigidaire 218859701 single solenoid water valve and what does it do?
The 218859701 is a single solenoid water inlet valve used on many Frigidaire refrigerators to control water flow to the ice maker or water dispenser. When the fridge requests water, the control board sends voltage to the valve solenoid, the valve opens and allows water from the household supply line into the ice maker fill cup or dispenser tubing.
What are the common symptoms of a failing 218859701 valve?
Typical symptoms include: no water to the ice maker or dispenser, very slow or weak fill, continuous water flow (valve stuck open), audible humming or buzzing from the valve, or visible leaks at the valve body or fittings. Any of these indicate the valve might potentially be clogged, mechanically failed, or electrically faulty.
How can I test the water valve to determine if it’s bad?
First,check that the fridge is getting the correct control voltage when a fill is requested (activate the ice maker or dispenser) – this is usually line voltage in North America; use a multimeter and follow safety precautions. Then test the solenoid coil for continuity with a multimeter; an open coil indicates failure. also inspect the valve inlet screen for debris and verify household water pressure and the water filter are not restricting flow. If the valve receives the proper voltage but the valve doesn’t open, the valve is highly likely defective.
Can I clean or repair the 218859701 valve instead of replacing it?
Minor restrictions can sometimes be cleared by removing debris from the inlet screen, but internal diaphragms and the solenoid coil are not serviceable. If the valve sticks, leaks, or the coil is electrically open, replacement is the recommended and reliable fix.
How do I replace the 218859701 valve safely?
Turn off the refrigerator power and shut off the water supply before starting. Access the valve (usually at the back lower section), disconnect the electrical connector(s), and disconnect the water line (have a towel/container ready). Remove mounting screws and install the new valve using the original fittings and seals. Reconnect water and power, then check for leaks and proper operation. If you’re not comfortable working with water and electrical connections, hire a qualified technician.
is the 218859701 valve compatible with my refrigerator model?
The 218859701 is used on many Frigidaire models but compatibility varies. Always verify fit by checking your refrigerator model number against the part listing from Frigidaire or the parts supplier before purchasing.Cross-reference charts or the manufacturer’s parts diagram are the most reliable way to confirm compatibility.
How long does replacement typically take and do I need special tools?
Replacement usually takes 15-45 minutes for someone with basic mechanical skills. Common tools needed include a screwdriver, adjustable wrench or nut driver for fittings, adjustable pliers, and a multimeter if testing. No specialized tools are typically required, but having Teflon tape or replacement compression ferrules may be helpful depending on the valve connection type.
Does the 218859701 come with a warranty and were should I buy it?
Warranty terms depend on the seller or manufacturer; many aftermarket and OEM suppliers offer limited warranties (commonly 90 days to one year). Buy from authorized Frigidaire parts dealers or reputable appliance parts retailers and keep your receipt and part number. If in doubt about warranty coverage, check directly with Frigidaire or the seller before purchasing.
