316536623⤠Frigidaire Ignitor/Orifice Assembly is a combined ignition and âfuel-metering component used onâ gas cooking appliances. The âassembly pairs an ignition elementâ – either a spark-type⣠electrode or a hot-surface/glow âignitor depending â¤on⣠the appliance design – with a fixed gas orifice âthat controls â˘the flow of fuel to â˘aâ burner. In practical⢠terms this part is a mechanical and electrical â¤subassembly that bothâ initiates combustion and sets the nominal gas flow⣠for a specific burner circuit.
Inside an appliance⤠the ignitor/orifice assembly directly interacts with theâ gas manifold⣠and the appliance control system: the ignitor providesâ the energyâ (spark or heat) to light the gas delivered thru the orifice,⢠while the orifice size and geometry determine the fuel delivery for correct combustion atâ the burner head. The assemblyâ also works with safety devices such as gas valves,flame â˘sensors or thermocouples and the control module âŁto ensure âthat gas isâ supplied onyl when ignition is âachieved. Proper installation, correct orifice sizing for the fuel type (natural gas vs. LP)and⢠clean, undamaged ignition surfaces â˘are all critical to stableâ flame, efficient combustionand âsafe⢠appliance operation.
In the âarticle that follows youâ will find a technical review of the 316536623 assembly covering its intended function, âŁmodel âŁcompatibility and fuel-typeâ considerations, common âfailure symptomsand practical troubleshooting steps.

Functionalâ Role and Performance Specifications of the Ignitor/Orifice Assembly
Theâ 316536623 frigidaire Ignitor/Orifice Assembly combines the ignition electrode and the metering orifice into a single service component that both⣠initiates combustion andâ establishes â¤the correct gas jet for stable flame characteristics. Mechanically,the electrode creates a spark sequence synchronized with the⣠gas valve opening,while the orifice determines volumetric flow at the⣠appliance’s nominal â˘manifoldâ pressure; âthe two functions must be aligned so â¤ignition timing,flame size,and âflame shape remain⢠within design limits. âŁTechnicians â¤should understand thisâ assembly âas a matched system: incorrect âorifice sizing, electrode misalignmentor electrode insulation damage will â¤produce the same operational symptoms (delayedâ ignition, weakâ or lifting flamesor continuous⢠sparking)⤠even when other components test⤠within tolerance.
performance and compatibility⢠are governed by the orifice diameter,â valveâ pressure, â¤and ignitor drive characteristicsand replacement assemblies should match the originalâ specifications for fuel typeâ (naturalâ gas vs.LP),manifoldâ pressure,and electrode geometry.Practical diagnostics include verifying presence âof drive voltage to the ignitor during valve open, â˘inspecting the orifice âfor carbon âŁor debris âŁthat restricts â˘flowand checking âŁelectrode position and â¤insulation â˘integrity; replacing the 316536623 assembly â˘typically resolves faults caused by a worn or fouled âelectrode or an âŁincorrectly âsized âorifice.â For field work, â˘confirm model compatibility â¤before installation and âuse basicâ bench checks-visual inspection, continuity, âŁand live voltage measurement-prior âto full burner âtesting â˘under load⤠to ensureâ safe, ârepeatable ignition and correct flame performance.
- Key features/symptoms: âignition sparkâ generation, gas flow metering,⤠clogged â¤orifice signs,â electrode wear and misalignment.

How the â316536623 Frigidaire Ignitor/Orifice â¤Assembly Operatesâ Within⣠the Appliance gas âandâ ignition System
The 316536623 Frigidaire âŁIgnitor/Orifice Assembly âcombines a calibrated gasâ orifice with an electrical ignitor to â¤controlâ and initiate combustion at a single burner. Mechanically the orifice⤠is a precision nozzle that sets the volumetric flow rate⢠for the burner port â˘when theâ manifold valve⤠opens; electrically the ignitor âprovides the required energy to ignite that metered âgas,either âŁas a spark pulse or as a hot-surface⤠element depending on the appliance design.⤠In operation the control module sequences⣠the components: it applies⤠voltageâ to⢠the ignitor,opens the gas valve only after the ignitor is active,and thenâ relies on a flame sensing device or thermocouple to confirm stable combustion. âMatching â¤the⤠correctâ assembly⢠toâ the appliance ensures the âorifice size, thread/mount configurationand ignitorâ type â¤are compatible with the manifold âpressure and regulator âsetting for âeither natural gas or LP service.
- Typical behaviors: ignition timing is limited âby control âsequencing; an âundersized orifice reduces âflame size and⣠causes poor heat,â an oversized âorifice produces⤠high or sooty flames.
- Compatibilityâ concerns:â interchange requires matching⢠gas type, connector âstyleand physical â¤mounting; conversion⤠between ânatural gas and LP ordinarily requires a different orifice or kit.
- Failure symptoms: clicking⤠without flame, delayedâ ignition, weak/yellow flameor a constant open valve indication from the control.
| Item | Description |
|---|---|
| Function | Meter âgas flow and âprovide âignition âenergyâ at the burner⣠port |
| System interaction | Works withâ the control board, manifold valveand flame sensor to â˘complete the ignition⣠sequence |
| Gas considerations | Orifice size and shape are selected for natural vs.LP gas and for expected manifold pressure |
| Common faults | Clogged orifice, worn âŁignitor element, incorrect âorifice for gas type, âloose electrical/seat connections |
For troubleshooting â˘or replacement, technicians should âverify âmanifold pressure, inspect the orifice for contamination, measure ignitor continuity or output per the⢠manufacturer’s service dataandâ confirm that the replacement⢠316536623 Frigidaire Ignitor/Orifice Assembly matches the â¤appliance model and gas specification.â In practical service âscenarios, a visible yellow âŁflame or soot depositionâ frequently enough indicates incorrect âgas metering, âwhile ârepeated âŁignition pulses with no⣠flame usually point to ignitor âŁor⣠gas delivery interruption; addressing the exact failure requires both â˘a mechanical check ofâ the orifice and anâ electrical check of the ignitor circuit and control â¤signals.
Diagnostic Indicators and Common â˘Failure Symptoms of the Ignitor/Orifice Assembly
The 316536623 Frigidaire Ignitor/Orifice âAssembly combines a âŁradiant ignitor⣠element andâ a matched gas orifice to initiate and shape the⤠burnerâ flame.The ignitor must draw sufficient current and reach âa radiant, even glowâ to allow âthe oven âsafety valve⢠to open; a â˘visibly dim, crackedor slow-to-heat â˘ignitorâ typically reduces currentâ draw â¤and prevents reliable ignition. The orifice determines gas flow and flame pattern – a partially cloggedâ or â˘incorrectly sized⤠orifice produces weak, unevenor yellow-sooted flames and⤠can causeâ longer ignition delays even when theâ ignitor itself⤠appears to be functioning.
Technicians diagnose âfailures by correlating observableâ behavior with electrical⢠and airflow checks: visually inspect âŁfor damage,â confirm proper connector fit and harness⣠continuity, observe glow time⢠and flame â˘shape during the ignition⢠cycleand isolateâ whether the fault follows the â˘ignitor or theâ gas feed. Practical troubleshooting âsteps include verifying continuity â¤and operation of the ignitor, checking for restricted gas passages or debris in the orifice, confirming âorifice âŁsizing for the fuel âŁtypeâ (natural âgas vs. LP)and swapping âthe assembly with âaâ known-good unit when possible to narrow the⤠fault to the⢠part or⣠an upstream control. Documenting symptoms suchâ as delayed ignition, âconsistent flame âinstabilityor sootâ accumulation helps⢠determine whether to replace the entire assemblyâ or address a specific â˘subsystem like the⢠regulatorâ or burner ports.

Replacement âConsiderations, âModelâ Compatibility and StepâbyâStep â˘Installation and Troubleshootingâ Procedures
The 316536623 âFrigidaire âIgnitor/orifice Assembly integrates the ignition element with the gas â¤metering orifice to provide â¤reliable spark/glow ignition âand âcontrolled gas flowâ on compatible Frigidaire ranges and â¤ovens.â The ignitor providesâ the thermal or electrical⤠energy required⢠to ignite the gas,â while the orifice âŁfixes⢠the volumetric flow âŁfor a given manifold pressure and fuel type; mismatched orifice size or orientation will produce erratic flame characteristics⣠or âpoor combustion. Verify âcompatibility by matching the OEM part number, mounting flange geometry,â electrical connector styleand the fuelâ type âdesignation (natural gas vs. âŁLP), since orifice diameter differs between fuels â˘and âsome models â¤use different⤠manifold⢠pressures even tho the externalâ assembly appears identical.
Follow a âŁmethodical replacement âand troubleshooting⢠approach to⣠minimize âdowntime and avoid unsafe âconditions: first, shutâ off gas and disconnect power; then remove â˘the burner âcomponents, note connector pinout âŁand â¤mounting locations, âreplace the assembly âmaking sure the orifice seats⤠squarely and wiring is securedand⢠restore services⢠for functional tests. Useâ the checklist â˘belowâ to â˘prioritize⤠diagnostics and common âŁcorrective actions;⢠if ignition sparks but the flame is âweak or yellow,â confirm orifice cleanliness and properâ fuel selection; if there⤠is⢠no spark or the⢠ignitor shows â¤open âcircuit,⣠replace the âignitor assembly âŁand verify continuity âand supply voltage atâ the â˘connector before⣠and after replacement.

Q&A
Whatâ is the 316536623 Frigidaire âŁIgnitor/Orifice Assembly âand what does it do?
The â316536623⤠is an OEM replacement ignitor/orifice assembly used âon certain⣠Frigidaire â¤gas ovens/ranges. It âŁcombines the hot-surface ignitor (or spark/igniterâ assembly depending onâ model) with the gas âorifice or gas valve interface so â˘the burner receives the correct amount of gas and aâ reliableâ ignition source. Its job âis âto heat orâ provide âa spark to ignite the gas âwhen the⢠oven or burner is turned on⣠and to â¤meter the gas flow forâ correct combustion.
How can âŁI tell if the âŁignitor/orifice assembly is faulty?
Common âsymptoms⣠of a failing assembly include âŁdelayed ignition (you âhear âa pop âor âseeâ a brief flash), âthe oven taking a âŁlong time to⣠reach temperature, âthe burner⣠not lighting at all, a weak or yellow flameor intermittent operation. âVisible damageâ such as cracks, broken â¤ceramic,⤠corrosionor aâ discolored/glazed ignitor element are also signs it should be⣠replaced. If you smell gas without ignition, stop andâ take safety precautions immediately.
How â¤should Iâ test the ignitor/orifice assembly?
do aâ visual inspection first (cold, â˘power off). For⣠electrical checks, verify continuity âŁwith a multimeter and, for⢠a⣠workingâ hot-surface ignitor, verify it glows⣠when the ovenâ isâ powered and the burner is commanded on.â Technicians often use a â˘clamp ammeterâ to âŁmeasureâ current âŁdraw âŁagainst the manufacturer’s service âspecification â(a healthy hot-surface ignitor âtypically draws a few amps when heating). For âgas-side â˘checks,⣠ensure the orifice is the âcorrect size for the fuel type and ânot⣠blocked.If you⢠are not trained on gas appliance testing, âhave a qualified service technician perform these checks.
Is â¤the â316536623 assemblyâ compatible with my âFrigidaire⣠appliance?
