WB24X10091 GE Oven â¤Switch Ignitor is⢠a⢠replacement ignitor⣠assembly designed for gas oven and range applications; as a component it functions as âthe electrical heating element and switch mechanism that initiates⣠and controls burner ignition. âThis âpart is a field-replaceable componentâ that combines a âresistive heating⣠element (theâ ignitor) with âthe⢠switching/interface required to signal and âallow gas flowand it is indeed⣠engineered to integrateâ with⣠the oven’sâ ignition and safety âsubsystems rather than act as a standalone gas control device.
Inside âthe appliance the ignitor’s⤠role isâ toâ provide the heat necessary to open âa flame when the control âcalls for bake or broiland to interact directly with the oven⤠control board, the gas valveand any⣠flame-sensing or âŁsafety circuits. When the control âsendsâ voltage to the ignitor âit mustâ draw âŁsufficient âŁcurrent âand âreachâ ignition temperature within aâ specified time so the gas⣠valve can open; if âthe ignitor â¤fails â¤to reach temperature or theâ associated switch/electrical connection is faulty,â the control will âinhibit or time out⤠the gas valve. The⣠WB24X10091 thus sits⢠at the intersection of the electrical control systemâ and the gas deliveryâ system and is critical to safe, reliable ignition and toâ the appliance’s over-temperature and flame-failure protections.
In this article â¤readers will findâ a technical overview of how the â˘WB24X10091 functions in âa typical gas oven,guidance on checking â˘compatibility with specific GE models,common failure symptoms to watch for (such⤠as long â¤ignition times,no⣠ignition,or intermittent burner operation),step-by-step troubleshooting procedures including electrical checks and measurements,and practical replacement considerations such as mounting,wiring,torque and safety precautions. The focus will be on diagnostic methods and â˘installation practices that help technicians and experienced owners determine whether the ignitor assembly is the source of a âfault and how to replace it safely while maintaining proper interaction with the oven’s control and â¤gas systems.

Function and Role of the Oven Ignitor â¤in gas Valve Control Systems
The WB24X10091â GE Oven Switch ignitor âis a hot-surfaceâ ignitorâ that supplies the thermal âenergy and electrical load⢠required for the oven’s gas valve control system to permit gas flow and â¤ignition. Rather than acting as a mechanical⣠switch, the ignitor’s function is twofold: it heats to a temperature sufficient to ignite the incoming gas⣠and presents a predictable electrical characteristic to the control circuit and gasâ safety valves. Technicians â˘should understand â˘that correct operation depends on both proper thermal coupling toâ the burner and the âignitor’s electrical behavior;⢠a replacement must match the â¤original part’s connector, mountingand â˘electrical properties to ensure⣠reliable valve operation and safe ignitionâ timing.
In practice, the ignitor’sâ behavior âisâ used diagnostically and for compatibility checks. A failing WB24X10091 typically shows symptoms â¤such as prolonged glow time, failure to reach full brightnessor an open circuit⢠when measured with⣠a multimeter; âthese conditions prevent âthe control board or âgasâ valve from initiating gas⤠flow. When servicing, verify continuityâ and compare the operational glow and response under liveâ conditions to OEM expectations, ensure the harness and mounting secure thermal transfer to the burnerand replace âthe⣠ignitor if it exhibits cracks, excessive delayor altered⢠electricalâ characteristics.
- Common â¤symptoms: long glow before ignition, no glow, clicking without ignitionor oven not reaching set temperature.
- Service checks: continuity test,visual inspection for⢠cracks,and â¤confirmation of correct connector and â¤mounting orientation.

How the WB24X10091 GE Oven Switch Ignitorâ Works Inside âthe Appliance
The WB24X10091 âGE Oven Switch⤠Ignitor is a hot-surface igniter assembly used on compatible GEâ gas ovens to initiate burner operation by providingâ the thermal and⤠electrical conditions required â˘for the gas valve to âopen. the igniter heats to a visible orange/red glow; âas it â˘reaches⢠operating temperature its electrical characteristics change so that the oven control and gas valve see the required current and âvoltage conditions⣠to energize the valve. In some appliance designs the igniter⣠assembly alsoâ contains mounting âfeatures and a â¤mechanical switch or sensor interface that â˘must match⤠the oven’s bracket⣠and terminal â¤layout, so physical fit and terminal âcompatibility determine whether a replacement âŁwill operate correctly in a given model.
Functionally, the â˘part behaves as both a heater and a current-dependent control element: âŁa weak or aging WB24X10091 will still glow but may not draw sufficient current to⣠actuate⢠the gas valve reliably, producingâ long ignition times âŁor no heat at all. technicians diagnosing a âŁfailed âigniter typically âinspect for a steadyâ glow,measure circuit continuity âand resistance,and verify that the igniter’s âterminals and mounting match the oven’s harness – replacing the assembly only â¤after confirming âthese factors avoids mismatches. For practical â¤context, if an oven lights intermittently or takes many minutes to reach set⤠temperature, swapping in a correctly⣠matchedâ igniter assembly with the same⢠terminal â¤type and mounting orientation usually restores normalâ gas valveâ actuation âandâ predictable ignition timing.
- Common symptoms: slow preheat, noâ ignition, igniter glowsâ but gas does ânot flow.
- Diagnostic checks: visual glow inspection, continuity and resistance measurement,â verification of matching terminal/mounting.
- Compatibility considerations: match mounting bracket,terminalâ type,and physical length; confirm OEM or equivalent fitâ for theâ specific GE model.

Common Failure Symptoms andâ diagnostic Indicators forâ the WB24X10091 Ignitor
The WB24X10091 GE Oven Switch Ignitor serves as the electrical/thermal interface that allows the oven’s⢠ignition circuit or control switch to operate the gas⣠valve or heating element. Failures typically alterâ the part’s electrical characteristics or visible behavior: the element may no longer glow, the switch contacts can⤠stick or openor the deviceâ may show physical âdeterioration (cracks, charringor pitting) that⤠changes contact âŁresistance âand mechanical alignment. Compatibility ârequires matching theâ connector type, mounting footprintand electrical ratings to the oven control; a physically similar part with different resistance or âconnector wiring can produce intermittent operation or prevent the valve fromâ opening â¤even⢠if â¤it⢠appearsâ to fit mechanically. For example, a weakened hot-surface element can still⢠glow but draw insufficient⤠current toâ satisfy the control’s sensing circuit, resulting in delayed⤠or noâ valve actuation despite the appearance of a normal⤠ignition sequence.
- No heat⢠or oven fails â˘to reach setâ temperature
- Delayed ignition or long glow period before gas flow
- Continuous clicking or repeated ignition attempts
- Uneven heating across⢠bake/broil modes⣠or intermittent operation
- Visible damage,burning,or arcing at terminals or element
- Multimeter shows open âcircuit (OL) or significantly âincreased⢠resistance
Diagnosing the WB24X10091 requires a⣠combination â˘of visual inspection⢠and electrical measurements. Start⣠with âa cold âvisual âcheck⤠for mechanical damage and clean,⢠tight connector contacts; then verify supply voltage atâ the connector during a call for heat and⣠confirm continuity âwith a digital multimeter. An open âŁcircuit reading indicates a broken element âŁor openâ switch; measurable continuity with abnormally â˘high resistance suggests a degraded element thatâ may not pass the required⣠current under load. If voltage is present but theâ element fails to glow,the component has lost functional integrity evenâ when passive resistance appears acceptable; âŁthis usually⤠necessitates replacement rather than adjustment because filament⣠characteristics change with â˘age. â˘The table below â˘summarizes common diagnostic readings and their typical â˘interpretation.
| Item | Description |
|---|---|
| Open circuit on ohms check | Filament or internal âswitch contact is broken âŁ- â˘element will not function under load |
| High resistance vs expected | Degraded âelement that may not⣠draw sufficient current; causes delayed ignition or intermittent operation |
| Correct voltage present âbut no glow | Element failed electrically despite supply – replacement required to restore reliable ignition |
Compatibility, Replacement Considerations,⢠and Installation Procedures â˘for WB24X10091
The WB24X10091 GE Ovenâ Switch Ignitor âis a⤠replaceable heating/ignition âelement thatâ provides the initial thermal stimulus and switching function required to initiate â˘fuel flow⢠and⣠combustion in compatible gas ovens.â Functionally, the component â˘produces a predictable glow profile and⢠presents a â¤specific electrical⢠signature to the oven control and valve circuit; technicians use those behavioral cues (no glow, dim glow, âintermittent glow) to distinguish âŁignitor failureâ from valve or âŁcontrol âfaults.compatibility depends on connector type,mounting flange,lead length,and theâ control system expecting the ignitor’s electrical characteristics,so always verify âOEM cross-reference or physical fit before installing a replacement.
Replacement and installation require basic electrical â˘and â˘gas-safety⣠precautions plus⤠a methodical verification sequence to avoid repeat trips. Before replacing the ignitor, âisolate power and gas, document wiring orientationand inspect â˘the burner assembly for⤠obstructions or damage that could⣠mimic ignitor â˘failure. After installing the replacement, restore power/gas and observe the ignition sequence and valve response; âif the new âŁignitor glows⣠but theâ valve does not open,⢠troubleshoot theâ control and⤠valve circuits â¤rather than replacing the ignitor again.
- Safety: disconnect electrical power â¤and shut âoff gas supply âbefore⤠starting.
- Pre-checks: confirm part fit (connector, mounting holes, lead length) âand âŁmeasure continuity/resistance against OEM/service manual values.
- Removal: âaccessâ burner⣠cavity, unscrew mounting hardware, carefully disconnect terminals noting â˘polarity⤠and spade sizes.
- Installation: âsecure new ignitor without over-torquing, ensure proper clearance⣠from burner âŁparts, reconnect âterminals firmlyand replace panels.

Q&A
What is the WB24X10091⣠GE oven ignitor and what â˘does it do?
Theâ WB24X10091 is a hot surface â˘(glow-bar) ignitor used on many GE-family gas ovens. when the oven calls for⢠gas, the ignitorâ heats to a high âtemperature and drawsâ enough current to⢠open the oven gasâ valve âso gas â˘flows and⢠is ignited by the hot surface. It does not produce a spark â- â¤it glowsâ red-hot⣠to lightâ the⣠gas.
What are the common â¤symptomsâ of a failing WB24X10091 âŁignitor?
Typical âsymptoms include long⣠oven ignition delays (30â seconds orâ more), the oven burner never lights, the broilâ or bake burner clicks but no light appears, âthe oven â˘won’t reach âŁtemperatureor the ignitor no longer glows.â An⤠ignitor âcan show electrical continuity yet still be âweak and not reach âŁtheâ required temperature or current draw.
How can I test the ignitor to⣠see if it needs replacing?
First perform âa visual âcheck: when calling for heat the⤠ignitorâ should âglow bright orange/red withinâ a few seconds. For âan electrical check use a multimeter: verify continuity â˘(resistance) across the two ignitor leads â- many working units measure â˘roughly tens to low âhundreds⢠of ohms (commonly 40-150 Ί,but values vary by design).The definitive âtest is â¤a current (amp) draw check whileâ the oven attempts ignition; a healthy â˘glow ignitor typically draws about 2-3 amps⤠atâ 120V (varies â¤by design).Use a clamp ammeter on⤠oneâ lead to measure â¤without interrupting the circuit. Ifâ the amp âŁdraw is significantly below the âspecification,the ignitor⣠is⤠weak andâ should â˘beâ replaced.
Is replacingâ the⤠ignitor something a homeowner can do? What are the basic steps and safety precautions?
Many competentâ DIYers can replace it, but you must observe safety steps: disconnect electrical powerâ at â¤the breaker and shut off theâ gas supplyâ before âstarting. Typical steps: access âŁthe oven⤠burner area (remove oven floor/pan or pull the range), unscrew the âignitor⤠mounting âŁscrews, carefully disconnect the two-wire connector (note orientation), install the new ignitor (do not touchâ the⤠ceramic/glow surface with bareâ hands), reconnect wiring, reassemble, restore power and gasand test. Use insulated gloves and proper tools. Ifâ you are unsure or uncomfortable working with gas or mains electricity, âŁhire a qualified technician.
What âtools and⣠parts do I âŁneed âŁto replace the WB24X10091?
You’ll typically needâ basic hand âtools: screwdrivers, aâ nut driver â¤or socket set (often⣠1/4″-3/8″), needle-nose âpliers âforâ the connector, a multimeter or clamp ammeter for testingand â¤replacement fasteners if theâ originals areâ damaged. Use the correct⤠replacement â˘part (WB24X10091 or an approved OEM equivalent) and avoid touching the ignitor’s ceramic/glow element with bare fingers – âŁoils can shorten its âlife.
How long does it take âand âŁhow much does replacement usually cost?
Replacement labor for a technician is commonly⤠30-60 minutes depending onâ access.⢠Parts alone for the WB24X10091 typically run in the $20-$60 range â¤at retail; professional⤠service labor⣠varies by region, commonly $100-$250. If you do it yourself, expect⤠under an âŁhour if access âŁis straightforward.
After replacing the ignitor the oven still won’t light – âwhat else could be wrong?
If a new ignitor still doesn’t light the burner, possible causes include a faulty gas safety â¤valve (the valveâ won’t open if⣠it does not â¤sense âsufficient ignitor current), bad wiring or â¤a lose connector, a â˘failed control board or thermostator blocked gas orifices. A weak⣠electrical⢠supply (voltage issue) can also prevent⢠proper âoperation. Aâ technician can measure voltage and current andâ test⣠the safety valve to isolate the fault.
does the ignitor have polarity⤠on the connector and how do I⣠confirm compatibility with my oven model?
most glow-bar ignitors âlike â¤the WB24X10091 use âŁa simple two-wire connector âwithâ no polarity – you can connect either wire to either terminal. To confirm compatibility, check your oven’s model number and the part’s⤠cross-reference in the manufacturer’s parts list or parts â¤retailers; âŁOEM part numbers and model cross-reference charts guarantee fit and performance.â If inâ doubt, provide âyour appliance model number to the⣠parts supplier or âtechnician before ordering.
