Functional⤠Role and Performance Specifications of the Ignitor/Orifice â¤Assembly
The 316536623⣠Frigidaire Ignitor/Orifice â¤Assembly integrates an electrical ignitor â¤elementâ with a matched gas orifice â¤to initiate and regulate combustionâ at âa burner port. âThe⣠ignitor provides the necessary heating or spark characteristic and âcurrent âdraw to âŁcause the âsafety gas valve âŁto open, âwhile⢠theâ orifice precisely⤠metersâ gas â¤flow so the⢠resulting flame geometry⤠and heat âŁoutput âmatch the appliance’s design. â˘Proper âoperation requires both correct electrical resistance/current behaviour from the âignitor and the correct orifice â˘size for the appliance’s âŁgas type and manifold pressure; mismatches â˘produceâ slow ignition,unstable flames,or âŁreduced heat output rather than improved performance.
Technicians evaluate the assembly by checking ignitor⢠resistance and warm-up current, confirming⣠connector and mounting â˘alignment,â and verifying the⣠orifice marking matches the service documentation or the appliance’s gas âŁtype (natural⢠vs. LP). Practical examples include replacing the assembly when âŁan âoven takes multiple seconds to light, when flames areâ yellow and sooty â¤indicating ârich mixtureor when â¤the âignitor never reaches âits required glow âŁand â¤theâ safety valve never opens. When ordering or⣠installing a replacement,â match the 316536623 Frigidaire Ignitor/Orifice Assembly âto the âmodel⣠number and⤠confirm any conversion⣠components required for alternate gas types to maintain âŁsafe â¤and predictable burner performance.

How the 316536623 Frigidaireâ Ignitor/Orifice Assembly Integrates and Operates Inside Frigidaire⢠Gas â˘Appliances
The 316536623 Frigidaire Ignitor/Orifice â¤Assembly is â¤an integratedâ ignition electrode and gasâmetering orifice that âmounts⢠to â˘the burner manifoldâ on compatible Frigidaire gas ranges and ovens. The ignitor creates the ionizing energy at a fixed position relative to the orifice so â¤the gas⣠jet is ignited immediately⣠as it exits the âmetering hole; the⢠orifice diameter⤠determines the âflow rate and the resulting flame geometry for â˘the appliance’s rated BTU. âElectrically the ignitor connector ties into the âappliance spark module orâ valve harness, while mechanically theâ assemblyâ seats into the⤠manifold âŁwith a bracket and seal to maintain alignment and âprevent leaksâ during âcombustion cycles.
In âoperation âthis assembly directly affects âignition timing, flameâ stability, âand⣠combustion efficiency: a clogged orifice, eroded electrode tipor misaligned⣠mounting will produce delayed ignition, lowâ flame height, yellow âtippingor repeated spark attempts. Technicians should verify⢠fuel type and âcorrect orifice sizing (natural vs âLP) âwhen⣠replacing⤠the unit, inspect the ceramic âinsulator â˘and wiring for cracks or corrosionand perform leak and spark/rectification checks⣠after installation. â˘Practical diagnostics include observingâ spark âlocation relative â¤to the gas jet, checking for âpartial obstructions with a âbore inspectionand comparing flame pattern to known-good behaviorâ for the appliance model.
- Primary â˘functions: position an ignition source⢠and meter â¤gas flow for consistent⤠flame.
- Failure symptoms:â intermittent âignition, weak or yellow flame, continuous sparking, âor⤠gas odor.
- Service points: verify orifice size for fuel,â inspect insulator and connector, torque mounting⣠hardware and perform leak â¤test.

Q&A
What is the 316536623 Frigidaire âŁIgnitor/Orifice Assembly and âwhat does âit âŁdo?
the 316536623 assembly is a replacement gas burner âcomponent⢠that combines â¤the âŁignition elementâ (sparkâ electrode or hot surface ignitor dependingâ on âmodel) and the orifice/orifice holder⤠that meters⤠gas to âthe burner. the ignitor creates the â˘spark or heat needed to ignite the gas, while the orifice controls the gas flowâ rate so the âŁflame burns at the âcorrect âsize âand shape.
How do I know â˘if the ignitor/orificeâ assembly is the reason a burner won’t â˘light?
Common symptoms include a âburner âthat won’t light or lights inconsistently, a weak or yellow/sooty flame, continuous clicking withoutâ ignition,â or â¤smell of gas⢠near the burner without ignition. To âŁisolate the part: listen/observe for ignitionâ attempts (spark⣠or glow), inspect the electrode/ignitor⢠and orifice âfor âdamage or blockage, âand checkâ wiring â¤and the ignition⣠module. Ifâ the ignitor shows no â¤spark/glowâ when the âburner âis called for and wiring and module are good, the assembly is likely⢠faulty.
Can â¤I â¤test the â˘316536623 ignitor/orifice âassembly myself,â and how?
yes, basic tests â˘can be done safely if you are comfortable working with appliances. First âdisconnectâ power and gas. Visually⢠inspectâ for cracks, carbon build-upor clogged orifice. â¤For a âŁhot â˘surface ignitor you can âtest continuity with a multimeter (no continuity suggests a failed element).For spark electrodes, reapply power and⢠observe whether⢠a spark is produced (do this only if âŁyou understand gas⣠safety â¤and there is no âgas leak). Always turn âŁgas off âbefore removing the orificeand neverâ use an open flame to test.If unsure, âcall a trained technician.
Is the â316536623 aâ direct replacement for my â˘Frigidaire â˘model?
