WB24T10071 GE Oven Gas Valve Spark Ignition Switch is a replacement electrical switch assembly used in GE gas ovensâ and ranges to control the spark ignition circuit; it is indeed a discrete electromechanical component âthat enables âor interrupts the ignition sequence initiated by⣠the appliance⣠control system. â˘As âa switch, it provides the interface between user or controlâ inputs and theâ ignition module/gas âvalve circuitryand is typically suppliedâ as a plugâin module orâ panelâmounted switch that matches GE appliance electrical and mechanical connections.
Inside the appliance,the ignition switch functions as âŁpart of the⤠ignition control path and interacts directly with the oven control board,spark/igniter module,gas valve solenoids and the appliance’s safety interlocks and âsensing circuits. when actuated, the switch permits the control board or ignition module to â˘generate highâvoltage spark pulses at theâ electrode⢠while also allowing⢠the control logic to open the gas valve at the proper time; conversely, a failed or intermittent switch âcan prevent spark âgeneration, cause continuous sparkingor inhibit gas valve actuation âthrough safety lockout behavior. Understanding⢠its electrical connections, mounting points and relationship to flame sensing and safety devices is vital for diagnosing ignitionârelated faults.
In âŁthis article readers⤠will find a technical⤠overview of the WB24T10071 part including its intendedâ function and where it⤠is indeed⢠typically used, guidance on compatibility âchecks with GE oven⣠models and control harnesses, common failure symptoms to watch for (for example no spark, persistent clicking, âor ignition lockout)and a structured approach to troubleshooting that covers inspection, electrical â˘checks⣠and verification steps. Replacement considerations such as correct part selection, connector and mounting âalignmentand basicâ safety precautions (power and gasâ isolation before service) will also be covered to help⤠technicians, engineers and appliance ownersâ determine when replacement is required and how to prepare for a safe, correct installation.

Function â˘and Role of the oven gas Valveâ Spark Ignition Switch in Gas Flow andâ Ignition Control
The WB24T10071 GE Oven Gas Valve Spark Ignition Switch is a small electromechanical switch mounted as part of â˘the valve/ignition assemblyâ that coordinates the spark âgeneratorâ and â¤gas-solenoid circuits during anâ ignition cycle. When the⤠oven control requestsâ a flame, the switch closes designated control circuits so the spark module receives power and the gas valve solenoids are allowed to be âenergized in the correct sequence. Functionally this switch â˘serves as a âtiming and safety âinterlock: âit ensures that ignition sparkâ is present before sustained gas flow âis⤠delivered and âit breaks the spark/gas circuit when âthe control calls â˘for â˘shutoff or âwhen a fault condition is detected by upstream safety â¤devices.
In practice, a failing â˘ignition switch âcan present as no spark,â continuous âsparking with no gas flow, â¤or intermittent ignition even though âthe⤠igniterâ and control board appear functional. Technicians â¤verify operation by commanding a heat⣠call and â¤measuring continuity/voltage at the switch terminals and observing whether the switch latches âŁand releases âin sync with â˘the control signals; replacement with the correct WB24T10071 part is necessary where terminal âlayout and voltage ratings must match. Typical troubleshootingâ steps and diagnostic observations include:
- Verify continuity â¤across switch contacts during a commanded ignition cycle.
- measure control voltage â¤to the spark module âand to the⢠gas valve solenoidsâ while the âswitch âis actuated.
- Inspect terminals for carbon tracking, pittingor loose connections âthat âcause intermittent contact.
| Item | Description |

How the WB24T10071 GE⤠Oven gas âValve Sparkâ Ignition Switch Operates Within the Control Board and Valve Assembly
The WB24T10071 GE Oven Gas Valve spark âIgnition Switch âŁis a small, line-levelâ switch mounted to⢠the gas valve assembly that coordinates the electrical path between the oven control board, the ignition moduleandâ the valve coils during the â¤ignition cycle. When the control board initiates a bake or broil call, it sequences voltage to â˘the âignition⣠module and relies on the switchâ to complete âor interrupt the solenoid circuit so gas is only admitted while a spark is â¤present; the âŁswitch therefore âenforces the timing relationship required for safe ignition⤠and⤠prevents the⢠valve from remaining open outside the ignition window.
- Primary role:â enable/disable valve coil current only during the ignition event.
- Common symptoms of âfailure: no ignition, continuous sparkingâ without valve opening, intermittent lightingor âcontrol-board fault codes reflecting valve circuit anomalies.
- Compatibility⤠note: replacements must match terminal layout and electrical â˘ratings to avoid miswiring or control-board protection trips.
| Item | Description |
|---|---|
| Mounting location | Attached directly to the oven gas⢠valve body so the board, ignition â¤module, â¤and valve share a â¤common mechanical/electrical interface. |
| electrical role | Switchesâ the solenoid/ignition â˘circuit per the â˘control boardâ timing to permit gas flow only during spark generation. |
| Troubleshooting tip | Observe the start sequence and verify continuityâ or intermittentâ contact under actuation; replace with an identical-spec unit when contacts fail. |
For practical service,â technicians check the ignition timeline and measure⢠switch continuity during the control board’s call for heat to isolate the switch âfrom ignition module and valve coil faults. Becuase the switch both carries current and âenforces timing, replacing theâ WB24T10071 with a unitâ that⢠matches the terminal arrangement and electrical rating is⢠necessary to maintain âcorrect interaction with the âcontrol board and to prevent nuisanceâ faultsâ or unsafe conditions.
Common Failure Symptoms⢠and Electrical/Mechanical âIndicatorsâ of Spark Ignitionâ Switch Faults
The WB24T10071 GE Oven Gas Valve Spark âIgnition Switch actsâ asâ the user-actuated contact set that completesâ the ignition circuit to the spark âmodule and,in some control architectures,provides the âŁsignal to the gas valve circuit during⢠the ignite cycle. In normal operation the mechanical actuatorâ closes a set of lowâimpedance contacts when the control knob isâ moved to the ignite position,allowing the control âmodule to deliver highâvoltage pulses for sparking and to âpermit gas flow onceâ a flame is established. Compatibilityâ is determined by physical mounting andâ terminal configuration; technicians â˘should match the actuator geometry and terminal spacing to the oven model before â¤replacement. Typical installer checks include inspecting the switch body⣠for heat deformation, measuringâ contact continuity while actuating the knoband verifying the presence of the control voltage specified⢠in⤠the oven service manual at theâ switch terminals.
electrical indicators of failure include open or intermittent continuity when â˘the switch is actuated, high contact resistance âthat prevents reliable spark or valve actuationand evidence of arcing or burned terminals. Mechanical indicators⣠include a⤠floppy or overly stiff actuator, cracked or melted plastic housingsand excessive wear on detents that prevents the switch from latching âin âthe âŁignite⢠position. âSuch as, a⣠multiâmeter continuity â¤check performed with the switch removed and the shaft rotated through the ignite detentâ will identify an open contact;⤠a visual inspection that shows âŁpitted contactsâ or carbon tracking typically correlates with intermittent sparking or continuous clicking even when the valve does â˘not open. Alwaysâ remove âpowerâ before performing resistance âchecks and consult the oven’s electrical schematic for expected control voltages before live testing.
- No spark at burner or â¤oven despite âproper âgas supply
- intermittent ignition or sporadic clicking â˘from the spark module
- Continuous âsparking without âvalve opening or flame establishment
- Visible arcing,â burn marksor⤠melted plastic near â¤switch âterminals
- Loose, brokenor nonâlatching actuator on the⣠control knob
| Item | Description |

| Visible damage | Burned or⣠pitted contacts and melted housing correlate with high âresistance andâ intermittent operation. |
| Testing note | Disconnect power for resistance checks; measure⤠control voltage⣠live âŁonly with appropriate safety⤠procedures and reference to the service âmanual. |
Replacement Considerations⢠and Installation Procedure for the WB24T10071 GE⣠Oven Gas Valve Spark Ignition Switch
The WB24T10071 GEâ Oven Gas Valve Spark Ignition Switch â¤serves as âthe user-switching element thatâ completes⢠the spark âignitionâ circuit⤠on compatible GE gas oven valve assemblies. It mechanically⢠or electrically couples the oven control âŁto the âigniter/spark module and the gas valve so âthat when the control calls for â˘burner ignition the switch permits the ignition pulses while also allowing the gas valve to âopen.Typical⢠failure modes⢠include a âloss of continuity across the switch contacts,intermittent contact⤠thatâ causes repeated clicking without ignition,or a stuck contactâ that prevents the spark sequence; in these cases the control may commandâ ignition but the spark will ânot âbe delivered to â˘the igniter.Confirm fit and compatibility â¤by matching the WB24T10071 part number⤠and the valve assembly part⢠number for your oven model before replacing, âasâ the switch is frequently enough integrated into the valveâ housing and different valve assemblies use different terminal configurations and mounting geometries.
Replacement requires basic appliance service skills, âa âŁmultimeter for continuity checksand a controlled procedure to avoid gas leaks or electrical hazards.⤠Before removing the old switch, verify the symptom (no spark, continuous clickingor failure to interrupt spark) and measure for continuity or â¤proper switching action; if the switch fails electrical diagnostics, replace⤠it and inspect⤠matingâ connectors for corrosion or heat damage.â Afterâ mechanical installation, verify correctâ terminal seating, ârestore gas and powerand run several ignition cycles while âŁmonitoring for proper spark âtiming and âŁforâ gas leaks at⤠the valve⢠connections; a handheldâ gas leak detector âor a soapy⣠water test should be used on all fittings.
- Safety first: Shutâ off â¤electrical power and âŁisolate the gas supply before disassembly.
- Document terminal positions and take a photo of the wiring before disconnecting to ensure correct reassembly.
- use a multimeter to â˘check for continuity âwhen the switch is actuated by âthe control signal; no continuity typically indicates internal failure.
- Afterâ replacement, perform a leak check on the valve fittings and observe at leastâ three⤠accomplished ignition cycles to confirm normal operation.

Q&A
What is the WB24T10071 and what does it do in⣠a GE oven?
WB24T10071 is a⢠replacement spark ignition switch assembly âused on some GE ovens. It âŁis the user-actuatedâ switch (or â˘part of the switch assembly) that tells the oven’s ignition system to generate a spark andâ open theâ gas valve so the burner can light. In short,â it provides the âelectrical command to the ignition module/gas â¤valve circuit when you turn a control knob or push âŁan igniter button.
What are common symptomsâ that the WB24T10071⢠switch is failing?
Typical symptoms include: nothing⣠happens when you try to ignite (no clicking/spark), intermittent ignition only sometimesor a control âthat does not change states when turned (knob feels loose or nonâresponsive). You may also âsee the igniter click but the gas valve not operating, which means the problem âcould be the switch or another⤠component-further diagnosis is needed.
Can I test the WB24T10071 with a âŁmultimeterand how?
Yes. Turn off electrical power to the appliance and, âif applicable, the gas supply. Access and remove the âswitch so âyou can probe⣠its terminals. Set the⢠multimeter to continuity orâ resistance. Operate the switch (turn to the ignite â¤position) and check for continuity between the appropriate terminals; in⤠the off position there should be no continuity where there shouldn’t be. âŁDo not test live circuits.If you’re unsureâ which terminals correspond⤠to which switch⢠positions, consult the⤠appliance wiring diagram orâ a â¤parts diagram â¤before testing.
Could a faulty WB24T10071 â¤causeâ continuous sparking even after the âŁburner lights?
Yes, a âfaulty switch can be one possible cause of continuous sparking, but âŁit’s not the â¤only cause.Continuous sparking can alsoâ be caused âby a failed flame⢠sensing circuit, ignition module,â wiring shortor control board issue.Diagnose by observing whether the switch changes⤠state when⤠operated, checking⢠continuityand testing downstream components (ignition module, flame sensor) before replacing the switch alone.
How⢠do Iâ replace the WB24T10071 safely?
