Function and Role of the â¤Ignitorâ Orifice Assembly in Frigidaire Gas Ignition Systems
The â316237805 âŁFrigidaire Ignitor âŁOrifice⣠Assembly isâ a mechanical âmetering⤠component â¤that⤠controls the jet⣠of gas presented to âthe ignitor electrode in Frigidaire⣠gas ranges â˘and ovens. Installed between the⤠manifold and the âignitor/burner tube, âŁthe orifice constrains flow to a calibrated apertureâ soâ the ignitor and burner receive⢠a predictable gas velocity and⤠volume;â this assures consistent spark-to-flame transfer and stable flame shape. Technically, the assembly affects⢠local gas âpressure, jet impingement on the electrodeand the⣠air-fuel ratio in the immediate ignition zone, so small changes in orificeâ condition or⣠sizing will alter ignition timing â¤and flame quality.
- Common symptoms⤠of âa degraded⣠orifice assembly: delayed ignition, persistent⢠yellow tipping, intermittent clicking,â or the need for⢠repeated attempts to⣠light.
- Inspection âand service steps: visually â¤check for clogging or corrosion, verify⤠alignment with â¤the ignitor tip,⢠and confirmâ part number/model⤠compatibility before replacement.
- Replacement âguidance: match orifice geometry and⣠thread/seat type⢠rather than âŁsubstituting by⤠external appearanceâ alone to preserve⤠proper flow characteristics.

| Primary role | Meter âgas flowâ to the ignitor and shape the ignition jet forâ reliable lighting |
In practical âŁservice work, âtechnicians treat the orificeâ assembly asâ a precision fluidâ element rather than a simple passage: cleaning⢠can restore performance if the aperture is only âŁpartially blocked,â but âdeformation, erosion,⣠or âŁincorrect sizing mandates⣠replacement to restore âmanufacturer-specified ignition behavior.⤠When diagnosing⢠ignition faults, confirm â¤upstream gas pressure and manifold integrity⣠first, then isolate the orifice assembly for flow âchecks or swap withâ a verified compatible unit to determine whether ignition anomalies âare caused by the orifice,⣠the ignitor electrodeor the â˘burner⣠geometryâ itself.
How⤠the 316237805 â˘Frigidaire Ignitor Orifice Assembly âŁOperates⣠Within the oven’s Gas â˘Delivery and âŁElectronic Ignition Circuit
Theâ 316237805 Frigidaire Ignitor⣠Orifice Assembly âis the metering ânozzle that interfaces the oven manifold⤠to â˘the burner head and determines âŁthe volumetric gasâ flowâ delivered whenâ the electronic ignition system opens âthe valve. Inâ ovens with hot-surface ignition, âtheâ control or valve electronics⢠will energize âthe â¤ignitor; once theâ ignitor reaches its operating temperature and draws the âexpectedâ current, theâ valve âŁisâ permitted â¤to⤠open and âgasâ flows âthrough the orifice into the burner. Correct⣠orifice size and seating are required toâ produce âthe intended flame shape and heatâ release for that model-an undersized orifice can cause delayed⤠ignition and weak burners,while an oversized â˘orificeâ may produce âsooting,yellow tips,or â˘excessive heat output âŁrelative to the oven’s⤠design and manifold pressure.
From a practical⢠troubleshooting and compatibility perspective, the⢠orifice assembly contains âno active âelectronics but âŁdirectly affects how the ignition circuit⢠and âgas valve behave under â¤load.Common âdiagnostic â˘indicators that point to orifice issues⢠include⤠intermittent ignition, sustained valve â˘cyclingor â˘a⤠narrow, noisy flame; these⢠should be evaluated alongside ignitor resistance and valveâ operation. Technicians typically inspect for port blockage, confirm the assembly âŁis the correct âŁOEM replacement⢠for the chassis and manifoldand verify seating torque and gaskets to avoid leaks. For⤠routine service, replace â¤with the specified part ânumber to maintain the⣠factory-calibrated relationship between manifold pressure, âŁorifice âsize, âand ignitor-driven ignition â˘timing.
- Typicalâ checks: visually inspect for â¤clogging, â¤confirm correct âpart number, âverifyâ ignitor⣠current drawand observe flame shape âduring ignition.
- Symptoms of mismatch: delayedâ ignition,⣠yellow/sooty flame,⢠frequent gas-valve cycling, âŁor loss of â˘temperature regulation.

Common Failure Symptomsâ and Diagnostic Tests for⣠ignitor Orifice â˘Assemblyâ Degradation
Theâ 316237805 Frigidaire â¤Ignitor Orifice Assembly is the combined meter-and-ignition component that controls the gas flow âŁto the burner⤠and âprovidesâ the ignition âŁenergy âat âthe âcorrect location. â¤In⢠normal⣠operation the orifice diameter andâ the ignitor position â¤produce a stable,blue âŁflame on first⢠strike; degradation âoccursâ when theâ small orifice â¤becomes partially blocked by carbon,rust,or debris,or âwhen the ignitor electrode â˘or⢠insulation is corroded orâ eroded. When the assembly is no â˘longer dimensionally correct or the ignitor output âŁhas âfallen, you will see delayed âignition, intermittent sparking, reduced flame heightor⢠yellow/sooty combustion that⤠indicates â˘incomplete â˘mixing or âlower gas⢠velocity.Because⣠the orifice size and mounting areâ specific, replacement must match the original assemblyâ for safe, predictable burner performance on compatible Frigidaire gas ranges and ovens thatâ accept this service part.
Shut âoff⤠gas and electricalâ power before⤠performing any inspection or⣠removal.â Common diagnostic â¤tests include a âvisual inspection âfor⢠blockage or electrode damage, a continuity/resistance check of the ignitorâ element âagainst â¤manufacturer âspecifications,⣠and an operational â˘check ofâ spark âgeneration orâ hot surface glow while measuring supply voltage.â technicians should also observe flame shape and color,⤠perform a soap-bubble leak test at fittings, âand, where available, measure manifold pressureâ to rule out upstream supply issues.If cleaning dose not restore consistent ignition or if the orifice shows signs ofâ erosion or the electrode is pitted, â˘replacement of the assembly is the corrective action; bench-testing with aâ known-good assembly is â˘a practical way to â¤isolate the fault between control circuits, supplyand the â¤orifice/ignitor âitself.
- Delayed ignition or multiple ignition âattempts – inspect⢠orifice for blockage and test⢠ignitor output.
- Yellow âorâ sooty flame â- check for partial blockage, degraded orifice geometryor insufficient air/gas mixing.
- No spark or no glow – verify continuity/resistance and supply voltage to the ignitor.
- Gas odor without ignition⤠– perform leak test and⢠verify valve/solenoid operation before âreplacing the âorifice.
| Item | Description |
|---|---|
| Visual inspection | Look for carbon âbuild-up, deformed orificeâ edges, cracked ceramic, âor corroded electrodes. |
| Electrical test | Measureâ ignitor continuity/resistance and verify⢠ignition voltage/currentâ against â˘OEM values. |
| Operational check | Observe â˘spark/glow and flame characteristics; compare to expected immediate blue flame. |
Compatibility, Replacement âConsiderationsâ and Step-by-Step Installation Procedures for 316237805 and Equivalent⣠Assemblies
The 316237805 Frigidaire⣠Ignitor Orifice Assembly combines the ignition element â¤with the gas orifice and mounting hardware soâ the â˘ignition sequence and fuel metering occur at a â¤single serviceable unit. Functionally, the ignitor provides the thermal or spark energy ârequired to âŁinitiate combustion while the orifice determines the âvolumetric âŁgas flow to the burner; both must⢠match⣠the appliance’s manifold pressure and burnerâ geometry to produce a stable blue â˘flame.Compatibility depends âon matching the electrical connector, mounting flangeâ patternorifice diameter âand â¤heat-rating âof the ignitorâ element -⣠aftermarket equivalentsâ can âsubstitute onlyâ when those parameters are identical to the OEM part.
when replacing the assembly, prioritize mechanical fit, electrical continuityâ and gas-tight sealing. Verify âthe ignitor’s cold resistance âagainst âŁthe âservice specification (typical hot-surface oven âignitors read in the⤠tens to â¤low hundreds of ohms) âand compare the visual geometry âof the orifice and locator pin with the removed part. â¤After installation, perform âa controlled light-off âandâ a leak â˘check at the manifold â¤joint; an improperly seated â˘orifice âor⤠damagedâ gasket can cause slow âignition, yellow tipping⣠ofâ the flameor gas leakage. Below⢠isâ a practical sequence techniciansâ use to replace and verify the assembly,â followed âŁby a âcompact âreference âtable for the most commonly checked parameters.
- Isolate utilities: shut off âŁelectrical power and the gas supply beforeâ beginning work.
- Remove grates andâ burner⤠components⤠to access the manifold and assembly; note orientation and screwâ locations.
- Disconnectâ the âignitor connector â˘and remove mounting screws; retain gaskets or transfer them to âthe new assembly âif undamaged.
- Compare the new unit to the old⢠for âconnector typeorifice âaperture and flange alignmentâ before installing.
- Install new assembly, hand-start screws, torque to manufacturer suggestion if available, then⣠tighten securely âto ensure âa gas-tight seal.
- Restore âgas, perform a soapy-water âleak â¤check at the⢠manifold joint,⢠restore âŁpower, âand observe ignition cycleâ and âflame pattern for âstability.
- If ignition is slow or flame quality⢠is âpoor, re-check resistanceorifice â˘seating, âŁmanifold pressure and burner ports for obstruction.
| Item | Description |
|---|---|
| cold resistanceâ (typical) | Many hot-surface ignitors measure roughly 40-120 Ί cold; confirm against OEM specâ for the specific âmodel. |
| Mounting & connector | Match â¤the flange hole spacing and the⣠ignitor harness connector (usually a 2-pin) to ensure âplug-and-play replacement. |
| Orifice â& sealing | Orifice aperture⤠and gasket condition control flow and sealing; replacements must âmatch diameter and seat⣠geometry to avoid âŁimproperâ flame or leaks. |
Q&A
What is theâ 316237805 Frigidaire Ignitor Orifice Assembly âand what âdoes it do?
The 316237805 â¤is anâ ignitor/orifice assembly used on certain Frigidaire gas ranges âandâ ovens. It combines theâ gas metering orifice with the âignitor/electrode âŁmounting so that the correct amount of gas is delivered to the â˘burner while the ignitor or spark electrode is positioned to â¤reliably light that gas.Proper function ensures a steady,⤠blue flame and reliable âignition.
How can⤠I tell if the âŁignitor â˘orifice assembly is failing?
Commonâ symptoms include burners or the âoven not âlighting, delayed âignition â˘(popping or large yellow âŁflames before steadying),â weak or irregular⣠flame shape, âŁcontinuous clicking⣠with no ignitionor gas smell.â Ifâ the ignitor element⢠shows visible damage or the⢠orifice⤠is⢠clogged â˘with debris/grease, replacement isâ highly âŁlikely needed. Always âruleâ out ignition âmodule,wiring,gas âvalve,and control board faults as well.
