316237704 â˘Frigidaire⤠Ignitor/Orifice Assembly is a combined ignition âand gas metering âcomponent designed for use in⣠Frigidaire gas cooking appliances. The assembly⣠typically integrates an ignition electrode or hot surface ignitor⤠with an orifice or orifice holder â˘that meters gas to a specific burnerâ port; it is a mechanical and electrical âsubassembly that mounts at the burner âhead and provides both the ignition source and the calibrated passage âfor gas⣠flow.
inside the appliance â˘the ignitor/orifice assembly initiates â˘and⤠stabilizes combustion by delivering a â¤spark⤠or heated surface at the point where a controlled gas jet issues from the orifice. It interfaces directly with the appliance’s gas manifold and âvalve (supplying theâ pressurized fuel), the burner head (where combustion occurs),â and â¤the âcontrol and safety circuits (which command ignition sequencing and verify flame presence).â Proper orifice sizing and ignition timing are critical for consistent flame geometry, âcorrect heatâ output,â andâ safe operation;⤠failures or misalignment can cause delayed ignition, incomplete⣠combustionor⢠unsafe gas leakage âprior âŁto ignition.
this article will âdescribe the assembly’s functional âdesign and operatingâ principles, list the appliance locationsâ and modelâ families where it â˘is indeed typically used, identify common âfailure symptoms âŁand diagnostic checks a technician can perform (electrical measurements, âŁspark/ignition observationorifice inspection and âflow verification)and âŁcover practical â¤replacement âŁconsiderationsâ such as correct orifice sizing, mounting orientation, sealing andâ connector requirementsand basic safety precautions to â˘follow when servicing gas⣠ignition components.

Functional Role ofâ the Ignitor/Orifice Assembly in Gas Flow regulation and Ignition⣠Control
The â 316237704 Frigidaire Ignitor/Orifice assembly integrates a âprecision gas âŁorifice with⢠an âignition â˘element to⢠control both metered âŁgas flow and the initiation of combustion in compatible Frigidaire gasâ ranges and ovens. The â˘orifice â¤isâ a⤠fixed-diameter opening that âŁestablishes⢠gas⤠mass flow for a âspecified âmanifold pressure, directly âaffecting burner BTU output⣠and steady-state flame âsize. âThe âignitor-either a⤠hot-surface â˘glow element or a âspark electrode depending⣠on âthe model-provides the â˘ignition energy and, in⢠hot-surfaceâ systems,â must âreach a â¤specified temperature before âŁthe safety â¤gas valve allows flow;⤠this interaction⢠controls ignition⢠timing, flame stabilityandâ safe operation of the burner circuit.
Performance and compatibility rely on matching orifice diameter, manifold pressure settings,⤠and âŁthe ignitor’s âelectrical characteristics âŁ(voltage, â˘connector typeand mounting). Common operational⢠symptoms such as delayed âignition,â continuousâ valve clicking, weak yellow flame,⢠orâ flame rollout frequently enough trace â¤to a degraded⢠ignitor, a â¤partially blocked orificeor an incorrect orificeâ size. Technicians should verify the OEM part number, âinspect and clean theâ orifice âport, measure ignitor resistance/current drawand confirm secure⤠mechanical and electrical connections to restore predictable⢠ignition behavior and maintain correct combustion characteristics.
- Key features: precision⤠orifice âsizing,â specified ignitorâ type âand electrical⢠rating, standard mounting flange andâ connectorand integrated sealing to preventâ gasâ leakage.

How the 316237704 Frigidaire Ignitor/Orifice Assemblyâ Works within the Burner system
The 316237704 Frigidaire Ignitor/Orifice Assembly combines⢠the ignition elementâ and the gas metering orifice into a single⣠service âŁcomponent that âŁlocates at âthe burner inlet. In operation, the â˘ignitor (either a spark electrode or a hot-surface element depending on the appliance design) is driven⤠by the cooktop’s ignitionâ moduleâ while âthe orifice controls⢠the volumetric gas flow into the burner throat. The timing âand coordination between the ignitor output and the gas valve are critical: in spark systems the module fires the âelectrode whileâ commanding the valve, whereas in hot-surface systems â¤the valve will not admit full flowâ until the ignitor reaches sufficient⤠temperature.â Proper seating, alignment of the electrode relative to the⤠burner portsand âmatching âthe orifice size to the appliance’s regulator/pressure specification⤠are necessary for stable, blue â˘combustion and predictable flame spread.
Technically, âthe assembly affects flame shape, ignition reliabilityand âcombustion stability; replacing it⤠with the correct âOEM part preserves the original orifice diameter and electrode geometry that the burner design requires. typicalâ field considerations include carbon fouling on the electrode, â¤a displaced orifice that â˘produces soft or yellow flames, â˘and intermittent sparking causedâ by cracked insulators or loose mounting. Technicians â˘should verify electrical continuity of the ignitor,⣠inspect â¤the orifice for obstructionand confirm the assembly’s mounting surfaces and grounding beforeâ declaring a âvalve or control faulty.
- Primary â¤functions:â initiate ignition, meter gas flowand position âŁthe ignition elementâ relative to âburner ports.
- Common symptoms of wear: delayed ignition, uneven flame, continuous clickingor flameâ lifting/sooting.
- Installation checks: secure âmounting, clean ports, correct electrode gap/position,â and appropriate part number â˘fitment.
| Item | Description |
|---|---|
| Ignitor | Produces spark or heat to⣠ignite the gas; electrical continuity and â˘insulation âintegrity âdetermine performance. |
| Orifice | Meters gas flow âfor correct fuel/air ratio; size âŁmust match appliance pressure and burner design⢠for âproper flame. |
| Compatibility | Designed to replace OEM assemblies on specified Frigidaire ranges-verify modelâ cross-referenceâ before installation. |
Common Failure symptoms and Quantitative Diagnostic Indicators for the⢠Ignitor/Orifice â¤Assembly
The 316237704 Frigidaire Ignitor/Orifice Assembly ⢠combines⣠a hot surface or spark ignitor with the matched gas orifice âto control reliable ignition and proper fuel metering in Frigidaire âgas ranges and ovens. The ignitor â¤provides the thermal âor electrical energy required to initiate combustion while the orifice â¤restricts gas flow to a calibrated rate forâ the burner. âIn practical âŁservice, the assembly must be tested both as an electrical â¤load (continuity, resistanceand operating â¤current) and⣠as⢠a gas⣠flow component (manifold pressure and âorifice cleanliness) because failures can be electrical, mechanical, âorâ due⣠to contaminated âorifices that change⤠the effectiveâ flow rate andâ flame characteristics.
Common failure symptoms⢠and quantitative diagnostic indicators help technicians pinpoint whether the ignitor,â orificeor ancillary controls are âat fault. âMeasurableâ signs âinclude open-circuit⣠or unusually high resistance at the â¤ignitor âleads, slow or âabsent⤠glow, extended ignitionâ time before gas valve opens,â and improper manifold pressure or flame shape⢠indicating âŁa restricted or⤠incorrect orifice. Use a multimeter â¤to check continuity⤠and resistance, a true-RMS meter or clampâ meter to verifyâ operating⣠current during ignitionand a manometer to confirm manifold⣠pressureâ against appliance specifications. Practical⤠examples: a cooktop that requires extended glow â¤time âŁ(over 40-45 seconds) before⢠the valve âŁopens likely has degraded ignitor heating â˘output;⢠a strong yellow or lifting flame with â¤correct pressure âcan âindicate an oversize orifice or air-fuel imbalance.
- Ignitor resistanceâ (cold): â¤approximately 40-120 Ί typical; open circuit indicates failed element.
- Operatingâ current (at 120 VAC): generally⤠2.5-3.5 A when drawing sufficiently to open the â˘gas valve; â˘lower current suggests degradation.
- Typicalâ glow/ignitionâ time: 20-45 â¤seconds to reach valve actuation on âmany gas models; considerably longer is a diagnostic flag.
- Manifold pressure:⤠natural⤠gas ââ ⢠3.5″ WC, propane â â 10″ WC;â deviations â˘point⢠to regulator/orifice issues.
- Flame sensingâ / rectification current: measurable â˘microamp-level currents (usually lowâ ÂľA); no flame signal⤠indicates poor ignition or sensor âfault.
| Item | Description |
|---|---|
| Ignitor âcontinuity | use multimeter; open = replace ignitor element. |
| Measured â¤operating current | Clamp or supply meter during glow: ~2.5-3.5 A typical at 120 VAC. |
| Manifold pressure | Verify â˘with manometer: natural gas ~3.5″ WC, propane ~10″ WC. |
Replacement Considerations, Model Compatibility, Installation Procedureand Troubleshooting Diagnostics
The â¤316237704 âFrigidaire Ignitor/Orifice Assembly combines the ignition electrode and the precision âgas orifice into⢠a âsingle replaceable unit that controls both âspark generation and fuel âmetering⤠atâ theâ burner. The ignitor produces the spark timing and energy required for reliable ignition âwhileâ the orifice determines flow⣠rate and burner pressure forâ a specific âfuel type (natural gas or LP). Compatibility is determined⢠by mechanical mounting, âŁvalve family,â electrical interface (spark module voltage⣠or continuous pilot/millivolt systems)and the âorifice diameter; substituting the assembly without matching the correct âorifice size âor valve characteristics can produce weak flame, delayed ignitionor sooting. Verify the appliance model number and gas type before âorderingand confirm that theâ replacement matches âthe original â˘mounting orientation and connector style to avoid alignment and âŁgrounding issuesâ that affect âspark performance.
Installers should follow a controlled procedureâ and â˘run basic diagnostics after replacement: isolate electricalâ power and gasâ supply, remove the burner cap and head to access the assembly,⤠note electrode gap and orientation, replace the assembly using original fasteners â¤and gaskets, then ârestore⢠services⣠and perform a functional and leak test. Diagnostics include measuring ignitor⤠continuity or⤠resistance, observing â¤spark intensity and âŁtiming, checking manifold pressure against specificationand evaluating flame shape and stability âŁunder load. â¤Common troubleshooting âŁindicators include continuous âsparking with no ignition (blocked orifice or no gas âpressure),intermittent spark (damaged electrode,loose ground,or wiringâ fault),and yellow/sooting âflame⢠(incorrect orifice or low âprimary air).
- Preparation: âshut â¤off gas and power, ventilate area.
- Remove burner components,⤠noteâ electrode gap and orientation.
- Replace assembly,â torque screws to â˘original spec,⣠replace gaskets.
- Restore gas and⣠power, perform leak test,⤠verifyâ spark âŁand stable flame.
- If faults persist,measure continuity,valve voltage,and manifold pressure.

Q&A
What âis the Frigidaire 316237704 Ignitor/Orifice Assembly?
The 316237704 is an OEM ignitor and orifice âassembly used on certain Frigidaireâ gas ovens/ranges. It âŁcombines the hot-surface or spark ignitor elementâ (whichâ lights the gas) â¤with theâ gas orifice that controls the fuel flow. Itâ is indeed a replacement assembly intended âto restore reliable ignition and correct gas flow âfor compatible models.
What symptoms â¤indicate this assembly⣠is failing and â˘needs âŁreplacement?
Common symptoms include the⢠oven/not igniting, long â¤ignition times, repeated clicking or sparking without flame,â the burner lighting⢠weakly or sputteringor the oven taking too long to reach temperature. If the ignitor glows but the burner never lights, the ignitor might potentially be weak âand not drawing sufficient â¤current to⢠open âthe gas valve.
How âcan I âtest the ignitor âto⤠determine if it’s bad?
You can â¤start with a visual check-does the ignitorâ glow when â¤the oven â˘is turned on?⣠Use a multimeter to âcheck for continuity (an âŁopen⢠circuit means the ignitor⢠is bad). A more definitive test is measuring the current the ignitor draws when⤠operating; âa weakened âignitor may glow but â˘not draw⤠enough current to open the gas valve. If you’re â¤not experienced testing live circuits orâ gas appliances,hire a qualified technician to perform these tests.
Can I replace only âthe ignitor or do I need the whole⤠316237704 assembly?
Some service parts are available individually, but⣠the 316237704 isâ sold as a combined â˘ignitor/orifice assembly. Replacing the complete âassemblyâ ensures the correct orifice size and fitment. âIfâ you do replace only the ignitor, makeâ sure it âis the correct type and rated for your appliance and that the orifice âremains correct â¤for â˘the gas type.
Is this part the sameâ for natural⣠gas and propane (LP)?
Not necessarily.The orifice size must match the gas type-natural gas andâ LP require âdifferent orificeâ sizes â˘and sometimes different pressure settings.Some âassembliesâ are made for a specific gas type; if you â˘convert â¤fuel types⢠you must use âŁthe correct orifice and follow the manufacturer’s conversion âprocedure. If uncertain, haveâ a qualified technician perform the conversion.
how difficult is installation and what safety precautions should I take?
Installation is a moderate DIY job for someoneâ pleasant with appliance repair: you âŁmust disconnect electrical power and turnâ off â˘the â¤gas supply, remove access panels, disconnectâ wiring and gas fittingsand âinstall the âŁnew assembly with proper gaskets and torque. after â˘installation youâ must check for gas leaks (soap solution or a⢠gas leak detector) and verify correct operation. As this âŁwork involves gas and line voltages, consider hiring âa certified technician ifâ you are ânot experienced.
Are there aftermarket âŁalternatives and is OEM necessary?
Aftermarket parts exist and can be less expensive,â but OEM parts like âFrigidaire’s 316237704 areâ designed for exact fit and are moreâ likely to include the correct â¤orifice â¤and mounting hardware. If you⢠useâ an⣠aftermarket part, confirm it is âcompatible with â˘your exact âŁmodel and gas type⣠and that it meets⣠safety â¤standards.â Using the wrong orificeâ or substandard ignitor can cause poor performance or create⣠a safety hazard.
After replacing⢠the assembly, what checks should I perform?
Restoreâ gas â˘and power⢠and⢠observe ignition behavior:â the ignitor âshould operate âŁand â¤the âburner should light promptly. Check forâ any gas leaks at fittings with a âsoap⢠solution or detector. Verify âthat the âoven reaches âŁtemperature and that flames are steady and properly sized â¤(noâ excessive yellowâ tipping). If âanything looks â˘wrong, shut off âŁthe appliance and contact aâ qualified service technician.
