functional Role of the Oven Switch Ignitor in⤠GE Gas oven Control Systems
The â˘WB24X10091⣠GE Oven Switchâ Ignitor is a glow-style ignition component used âin manyâ GE gas ovensâ to initiate and âcontrol burner⣠operation. When the oven âŁcontrol commands a bake or broil cycle, âthe control board supplies voltage to the ignitor, which then heats to⤠a luminousâ orange glow. A âproperly functioningâ ignitor bothâ reaches sufficient temperature andâ draws⣠the⢠required current so the safetyâ gas⤠valve â¤receives the signal⤠to open; if the ignitor failsâ to reachâ operating temperatureâ or its electricalâ characteristics change,the valve will not release gas and âthe â˘oven will not light.
Technicians should⣠treat the WB24X10091 as a âreplaceable element that must match the original inâ mounting, âterminal configurationand electrical characteristics. Verify compatibility byâ comparing part numbers,⢠connector typesand measured values against the âoven’s âspecification sheet before installation.⢠Common diagnostic steps include visual inspection forâ cracks⣠or damage,a âcontinuityâ check,and⤠observing the time-to-glow behavior during a powered ignition attempt; symptomsâ of degradation include delayed âŁlighting,repeated ignition âcycles,or⤠complete failure to â˘ignite.⢠For practical fieldwork, replace theâ ignitor with a⣠matched unit and â¤re-test the⢠ignition sequence rather than relying solely on âresistance readings, because a marginal ignitor can pass a cold⢠resistance check but still fail under âload.
- Primary function: heat-to-glowâ to enable â¤the â˘gas safety valve to â˘open.
- Common⣠symptoms ofâ failure: â¤noâ light, long ignition delayor repeated âattempts âto ignite.
- Compatibility checks: match part number, connector styleand mounting brackets.
- Service tip: observe live ignition sequence and compareâ behavior before and after replacement.

How the⣠WB24X10091 GE Oven âSwitch⢠ignitor Operates Withinâ the Oven’sâ Ignition and Control Circuit
The WB24X10091 GE Oven Switch Ignitor functions as the â˘electrical interface between â¤the oven control electronicsâ and âthe⤠gas valve, supplying the energy necessary to⤠ignite the burner âand presenting aâ predictable electricalâ load the control⤠board can monitor. In typical hot-surface ignitor systems the control applies line voltage to the ignitor; âŁas the element heats and âits âŁresistance⣠changes the control senses the current draw and then energizes the âgas valve.In some designs the ignitor also provides a signal-like behavior (through⤠its current signature) thatâ the âŁcontrol uses to confirmâ a prosperous warm-up âbefore âallowing gasâ flow, soâ the part⣠must match the original specifications â˘for resistance, connector typeand voltageâ rating to operate correctly with the rest of⢠theâ ignition âand controlâ circuit.
Operational behavior and practical compatibility matter â˘more thanâ cosmetic⣠fit: a physically similar element with different electrical âcharacteristics can heat too slowly â˘or draw too âlittle current, preventing⤠the control from opening the valve and leaving the oven unlit. Technicians typically verify function by checking âcontinuity, observing the element’s glowâ during start-upand measuring whether the control board registers the expected load before â˘the gasâ valve is energized. For practical troubleshooting,⢠verify connector pinout, mounting âposition (which affectsâ flameâ exposure and sensing), â¤and⣠that the replacement part is â˘specified for theâ same control scheme; mismatches⤠commonly present as âdelayed ignition, continuous sparking,â or a no-heat condition.
- Function: provides âignition energy and a measurable â˘load for the control board
- Behavior: heats to ignition temperature and presentsâ a current⢠signature the control âuses to actuate the gas valve
- Compatibility: â¤must âmatchâ resistance, voltage rating, connector,⣠and⤠mounting to ensure proper âoperation

Common⣠failure Symptoms, Electrical Signatures and OnâAppliance Diagnostic Indicators
The âWB24X10091 GE⤠Oven Switch Ignitor is a replacement ignitor assembly⤠used in⤠many GE gas oven control systems; it provides the hot-surface ignition function that brings the burner to ignition temperatureâ and also interfaces electrically with âthe oven âŁcontrol and gas valve circuit. In normal âoperation the ignitorâ draws â˘current⢠from the â¤120 VAC control circuit, heats toâ a visibleâ glowandâ permits âthe gasâ valve to open when it reaches the required current draw; compatibility dependsâ on terminal style, mounting footprint and⢠control âsequence, soâ techniciansâ should âŁmatch â˘harness connectors and model numbers âŁbefore installation. Disconnect power and gas before any inspection or measurement; visually check forâ a continuous glow, physical damage to the âceramic/glow elementand secure terminal connections as part of initial compatibilityâ and function⣠verification.
- No glow â˘at all or a cold⣠elementâ while â˘the âŁcontrol calls⣠for ignition (open âelement⢠or â¤no continuity).
- Delayed ignition or long glow⣠time before gas flow – symptom⤠of high resistance â¤or weakened element drawing insufficientâ current.
- Intermittent âŁheatingâ or oven shutting down after a â˘short run – intermittent internal break or⤠poor terminal contact.
- Gas odor with no ignitionor⤠repeated clicking without ignition – electrical sequence reaches valve but ignitor fails to produce required â˘current.
- Visible âcracking, chippingor burnt insulation at terminals indicating imminent failure â¤or short risk.
Electrical diagnosis focuses âon continuity and resistance checks at⤠the ignitor âterminals and on-applianceâ behavior during a call for heat:⤠a true âŁopen â¤(infinite resistance) indicates a broken filament,while an abnormally high resistance result⤠suggests a weakened element that âwill not draw the⣠requiredâ operating â¤current and âŁwill⤠cause slow⢠or failed ignition.â If âa technician can safely measure operating current,a functioning hot-surface ignitor typically draws a âfew amps when âheating; a âreading⣠well⣠below the expected current under load indicates degradation even âŁif cold-resistance â¤shows continuity. âUse the tableâ below as a fast reference for âŁcommon electrical signatures and â˘on-oven indicators; values are typical ranges and⢠must be confirmed against the oven’sâ service â˘literature for âthe âspecific model.
| Item | Description |
|---|---|
| Cold resistance | Typically âaâ low-to-moderate ohm⢠value (tensâ toâ low hundreds of⢠ohms) – â¤continuity expected; a reading of open/infinite indicates a failed element. |
| Operating current | Typical in the range of a few⣠amps⤠under 120 VAC load; âsubstantially lower current under load âindicates⤠weakened element (consult⤠model⢠spec). |
| On-appliance indicator | Visible red/orange glow within seconds of a call for âheat and then gas valve actuation; âdelayed or no â˘glow indicates fault. |
| Failure modes | Open filament,increased resistance,intermittent contact at terminals,or short to ground leading to control lockout or noâ ignition. |
Replacement⢠Considerations,â Mounting Hardware, Electrical Connections and Safe Installation Procedure
The WB24X10091â GE Oven Switch Ignitor is âa replacement ignitor assembly that providesâ the required heat âand electrical load characteristics to allowâ the oven’s âgas control valve and controller to⤠sequence properly. In service, the ignitor â¤heats to a high â˘temperature and draws the â˘expected current so theâ gas valve sensesâ a load and opens; an ignitor âwith incorrect resistance orâ damaged terminals willâ produce delayed ignition, repeated âvalve cyclingor â¤failure to light.Verify compatibility by matching the mounting footprint, terminal typeand âharness connector to âthe oven model; visually similar ignitors can differ in mounting⤠hole spacing or lead length, which âcan âaffect âflame alignment â¤andâ gasket âsealing when installed in the âburner box.
Installation requiresâ both correct mechanical fasteningâ and safe electrical connection to ensure reliable operation andâ to prevent gas leaks or arcing.Before starting work: disconnect the âappliance âfrom mains power and â¤close the⣠gas âsupply, then â˘verify zero voltage at the harness. Use the original⣠mounting âhardware âor equivalent stainless fasteners with proper insulating âwashers to secure the ignitor âŁwithout â¤crushing the ceramic element; ensure the ignitor face is oriented to â˘the⣠burner port so the flame properly contacts theâ sensor area. For âŁelectrical connections, engage âinsulatedâ spadeâ terminals or theâ OEM plug, maintainâ strain relief on the wiring,â and inspect solder joints or âcrimps for⢠corrosion. After installation, restore power and gas, confirm correct ignitionâ timing⣠through several cyclesand perform a⢠gas leak check at the fittings.
- Pre-install checks:â confirm part number fit, inspect harness and gaskets, measure resistance per service â¤data.
- Mounting: secure âwith original-style screws and âŁmaintain alignment to burner port.
- Electrical: use âcorrect insulated spade connectors⢠or OEM plug; avoid loose or exposed âŁconductors.
- Post-install tests: leak check, several âignition cyclesand verify âŁstable flame and valve operation.

Q&A
What is⢠the WB24X10091â and what does it do in a GE⣠oven?
WB24X10091 is aâ GE replacement hot⢠surface igniter used âon gas ovens. Its job is to heat to a high temperatureâ (glow) so the â¤oven’s gas⤠safety â¤valve⤠will open â¤and allow gas to flow to the âburner, where the âigniterâ thenâ lights⣠the gas. It is âan electrical component âmounted at or âŁnear the burnerâ assembly.
What symptomsâ indicate âthe WB24X10091 igniter is failing?
Common symptoms of a failing igniter includeâ the âŁoven not heating or taking a long time to light, the igniter glowing weakly or not at all,â the burner â˘clicking or the gas⣠valveâ clicking without ignition, â¤and sometimes a persistent electronic â˘fault code. If you smell â˘gas âwithout ignition, âstop using theâ ovenâ and âtreat it as a âsafety hazard.
How can I test the â˘WB24X10091 âto see if it needs replacement?
First disconnect power⤠and gas. âVisually inspect the igniter for cracks or breaks. Reconnect power and observe: a⣠healthy igniter should âŁglow â¤bright â¤orange within 30-60 seconds. You âcan test electrically with a âmultimeterâ for continuity; an open circuit (infinite resistance) means replace the igniter. For aâ more definitive â˘test, measure the current draw with the â¤oven âattempting to light (technician-level test): a âweak â¤igniter âthat does â˘not draw its rated⢠current may⢠glow but won’t âŁopen the gas valve. âAlways⣠compare âŁto the oven/service manual specs when â¤available.
Can I replace the⢠WB24X10091 âmyselfand what⤠are âthe âbasic steps?
Yes, a competent DIYer can âusually replace âit,â but you must follow safety precautions.⣠Turn off âelectrical power at â˘the breaker⢠and shut offâ the gas supply.â Access the â¤igniter by âremovingâ the oven âfloor/broiler â¤drawer or back panel according to yoru model. Unplug theâ igniter wiring harness, remove its mounting⢠screws, install the â¤new igniter without âtouching âŁthe⢠ceramic with bare hands, âsecure it, reconnect âthe harness, ârestore power/gasand test.If youâ are unsure⤠or smell gas,stop⣠and call⢠a qualified technician.
How do I make âsure I order the correct âreplacement âpart?
Confirm compatibility âby âmatching the oven model number and the OEM part number. Use your âŁoven’s model number (usually on the oven âŁframe or inside âthe âŁdoor jam)⢠and verify WB24X10091 is â¤listed asâ a compatible⤠replacement in⣠the parts diagramâ or from a reliable âŁpartsâ supplier. Alsoâ confirm connector type, mounting styleand electrical âŁratings match to ensure⢠proper fit andâ safe operation.
How long should âthe igniter⣠take to glow and light the burner?
On a healthyâ hot surface igniter you should see it begin âŁto glow withinâ a few seconds of the bake/broil cycle âstarting andâ reach full bright orange⣠within âabout â¤30-60 seconds, at which point the gas valve should open and the⣠burner should ignite almost immediatly. If it â˘consistently takes much longer or never reaches full glow, the igniter is highlyâ likely weak and should be replaced.
After replacing the igniter, the â¤oven still won’t light. What elseâ could⣠beâ wrong?
If the new igniter glows âbut the burner does not light,possible causes include âa faulty gas safetyâ valve⤠(it may notâ open even with sufficient current),damaged⤠wiring âor connectors,a bad control â¤board,incorrect⣠installation or âmisalignment of the igniter,or a âblocked burner port. Check â˘wiring and connectors for damageâ orâ corrosion, ensure the âŁigniterâ is positioned correctly, âŁand âŁif wiring is good consider testing the âŁgas âŁvalve or calling a qualified technician.
Are â˘there any safety precautions I should no when handling or âinstalling⢠the WB24X10091?
Yes.⤠Always disconnect electrical power and shut off the gas before working⤠onâ a gasâ oven. Do not test ignitersâ with an open gas line. If you âsmell gas, âventilate, âŁdo not â¤create⢠sparksand contact your gasâ utilityâ or a technician. Avoid touching the igniter’s ceramic or glass⢠surface with âbare hands as âoils⤠can create â¤hot spots andâ shorten âŁits life. Handle the new part carefully and follow â¤torque âŁand âmounting âŁinstructions from â¤the service manual.
