316237805 Frigidaire Ignitor Orifice Assembly is a âŁcombined ignitionâ and gas metering component used in Frigidaire gas cooking appliances; â¤it integrates the ignitor element with the orifice that metersâ fuel to the burner and is typically mounted on the oven or cooktop burner assembly.â As a mechanical and⣠electrical â¤subassembly, it comprises the ignitor â(either a hot surface or spark-style element), âthe gas orifice/nozzle sized to a specific flow rateand the⤠mounting hardware and seals required to position the orifice⢠relativeâ to the burner head. Technically, it is categorized as a field-replaceable⣠ignition/metering part andâ is built âŁto withstand high temperatures, periodic thermal â¤cyclingand⢠exposure to combustion â¤products.
Functionally, the âŁignitor orifice assembly⣠sitsâ at the â¤interface between the appliance’s gas delivery system (manifold and gas valve) and the combustion zone; it interacts directly with the gas valve that supplies pressurized fuel, the burner â˘head where⣠mixing and combustion occurand the appliance’s control system that âsupplies power to the ignitor âand âmonitors flame presence. âThe ignitor initiates combustion either by providing a hot âŁsurface or âŁa spark at theâ point âwhere gas is released through⤠the orifice, â¤while the orifice controls volumetric flow and thus the air-fuel⤠ratio at the burner. Becauseâ of these roles,theâ assembly affects ignition timing,flame⣠stability,heat output,and canâ influence âsafety interlocks tied to flame sensing and gas shutoff behavior.
In this article readers will find a â¤practical technical overview âof the⢠316237805 frigidaire âIgnitor Orificeâ Assembly covering how the part functions, where it is applied within âFrigidaire⤠ranges⣠and ovensand which appliance models commonly use the configuration.â The âarticle will also describe commonâ failure âsymptoms â(delayed ignition,weak or uneven âŁflame,continuous â˘sparking,or no ignition),step-by-step troubleshooting⣠checks (visualâ inspection,electrical continuity/resistance of the⣠ignitor,orifice clogging/obstruction,manifold pressure verification,and control signal verification),and key replacement considerations such as âcompatibility,mounting/sealing practices,leak⤠testing after installation,and safety precautions to follow during service.

Function â¤and Operational Role â˘of the â˘Ignitor Orifice Assembly in â˘Frigidaire⢠Gas⤠Burners
The â˘316237805 Frigidaire â˘Ignitor Orifice Assembly is a combined component that both âmeters gas âto the burner and locates the ignitor element âto ensure repeatable ignition.In operation the orificeâ element provides a fixedâ restriction that sets the volumetric⤠gas âflow âŁand therefore the⣠flame sizeâ and energy available for ignition, while the assembly’s mounting and alignment position the âŁignitor or âsparkâ source so the âignition energy is applied directly to the gas jet.Proper orifice â¤sizing, sealing and alignment are critical â˘for stable combustion and â˘safe operation; an incorrectly sized âor âŁimproperly seated orifice âwillâ cause poor flame characteristics,⤠delayed ignitionor⤠pilot instability âŁdespite⣠a functioning ignition module âor gas valve.
The assembly interacts âdirectly with the range’s⢠gasâ valve,â burner head and electronicâ ignition system; it does not regulate⢠gas pressure but defines the jet through which the âburner⢠receives fuel, so technicians should confirm⣠manifoldâ pressure and valve operation before changing orifice parts. Common practical considerations include verifying that replacement parts âmatch â¤the OEM specifications and âthatâ theâ ignitor gap and mounting screws are torqued toâ specification toâ prevent misalignment. typical âsymptoms indicating the 316237805 Frigidaire Ignitor Orifice Assembly âmay need âŁinspection âor replacement include intermittentâ ignition,â sustained clicking from⤠the spark module, weak or yellow-tipped âflamesand gas odor at ignition. For field service, check âmanifold pressure, â˘continuity of the â˘ignitor circuit, âand âtheâ physical conditionâ of⣠the orifice seat before replacing the entire assembly.
- Features and inspection points: fixed orifice â¤sizing, ignitor positioning, sealing surface condition,⤠and mounting alignment.
- Failure âŁsymptoms:â delayed ignition, weak flame, continuous spark attemptsor⤠gas leakage⢠at the burner head.
- Replacement guidance: match part number or verified OEM equivalent, inspect âŁgasketsand confirm electrical continuity of the ignitor.

How the 316237805 âŁFrigidaire Ignitor âOrifice assembly Works Inside the âAppliance: Gas Flow, Ignition Timing,â and Thermal Interaction
The 316237805 Frigidaire Ignitor Orifice Assembly combines a precision gas orifice with theâ mounting interface for the ignitor so that gas metering⢠and ignition initiation occur inâ a controlled, repeatable way. Installed at the burnerâ manifold, the assemblyâ converts manifold pressure into a⢠calibrated jet through a small-diameter orifice; the â¤jet’s âŁflow rate and angle relative âtoâ the ignitor determine⤠how quickly and where the combustible mixture reaches ignition âŁtemperature. Proper â¤placement of the ignitor element â(hot-surfaceâ or âspark electrode depending on model) within the assembly is required to establish a stable⢠flame promptly after the â¤control valveâ opens, which⤠minimizes â˘unburned gas accumulation and prevents⢠delayed ignition âŁevents that⢠technicians observe as popping or noisy light-offs.
When the valve opens, ignition timing is⣠governed by the control circuit energizing the âignitor â˘and â¤the transientâ response of the gas jet; any restriction, âpartial blockageor wrong â˘orifice size alters flow dynamicsâ and canâ produce a weakâ or yellow flame or intermittentâ shutoff detected by the appliance’s âflame-sensingâ system.Thermal interaction between the burner flame and the âmetal body of âŁtheâ assembly affects â˘local gas density and flame-holding âcharacteristics-metal absorbs heat and can âŁslightly âŁchange flow behavior â¤during steady-state operation. For compatibility and safe replacement,ensure a â˘replacement part âmatches the original orifice diameter,mountingâ thread,and intended manifold â¤pressure; practical service checks include visual inspection for âsoot or debris,continuity/operation test of the ignitor,and measuringâ manifold â¤pressure relative to âthe⣠appliance specification to⣠confirm correct operation.
- Gas â˘metering: precision⢠orifice controls volumetric flow and jet⣠velocity.
- Ignitor â¤alignment: âŁignition element must⢠sit within a narrow tolerance for reliable ignition.
- Ignition timing: coordinated valve-actuation and ignitor energization prevent gas buildup.
- Thermal effects:⣠assembly mass and heat transfer influence steady-state flame âstability.
- Common⢠symptoms⢠of issues: delayed ignition, yellow⤠flame, repeated reignition⣠clicksor flame-sensor shutdown.

Diagnostic Indicators and â˘Common Failure Symptoms â˘of⣠Ignitor Orifice Wear, Cloggingand Electrical⣠Faults
316237805 Frigidaire âŁIgnitor Orifice Assembly â is a service replaceable component that meters and directs gas to the âignition region while providingâ the mechanical â¤andâ electrical interface for the⤠ignitor/electrode.⣠The assembly typically includes a precisely sized orifice,â a mounting flange that aligns the nozzle to the burner portand insulation that isolates the â¤electrode.⤠Correct âorifice diameter, seatingand âalignment⣠determine â˘volumetric⤠flow and âflame geometry; deviations from specified â¤tolerances (from wear,⤠corrosionor mechanical damage) change mixture⢠and flame stability. Compatibility â˘must be checked against⤠the range âmodel andâ the valve â¤outlet pressure because improper matching produces slow light, pulsating flame,⣠or sustained yellow⤠combustionâ even â¤if the electrodeâ and valve appearâ to function normally.
Common diagnostic indicators separate mechanical obstruction and âorifice wear from electrical faults inâ the ignition circuit. Persistent rapid clicking without â˘flame,safe shutdowns,delayed ignition with a strong initialâ pop,or âvisible sooting⣠pointâ to partial blockage or deformedâ orifice geometry; a fully silent system with âno âspark normally implicates the electrode,wiring,or ignition transformer. Technicians typically perform a visual âŁinspection â˘for carbon and debris,a pressure- âor flow-check at the valve,and â˘continuity/insulation tests on the electrode wiring (power off) before replacing the â˘assembly. Forâ practical troubleshooting, clear the orifice âwith compressed air after shutting off gas, verify spark presence visually with⣠the burnerâ removedand âconsult âthe applianceâ wiring â¤diagram to isolate coil/transformer faults beforeâ assuming the orifice assembly âŁis âdefective.
- Rapid clicking but no ignition – suggests clogged or partially blocked orifice âŁor failed gas valve âseating.
- Delayed ignition or loud⤠ignition âpop – indicates reduced âflow from partial obstruction or âworn orifice increasing ignition time.
- Yellow, liftedor sooty flame – â¤often caused by incorrect â˘orifice size, obstruction altering air/gas â˘ratio, âor contamination on the burner âŁports.
- No spark observed – electrical faultâ in electrode, wiringorâ ignition transformer rather than the⢠orifice itself.
- Intermittent operation – can be caused by thermal expansion effects on â¤a cracked insulator or intermittent electrical connection.
| Item | Description |
|---|---|
| Physical inspection | Check orifice aperture,â electrodeâ alignmentand signs of corrosion âor carbon buildup. |
| Functional test | Confirm spark generation,gas⤠flow,and flame stability under controlled conditions; clear debris and retest. |
| Electrical check | With power â˘off, test continuity of electrode wiring and visually inspectâ connector insulation⣠for cracks⣠or arcing marks. |
Compatibility, replacement⤠Considerations, Step-by-Step Installationand⤠Troubleshooting for the⤠316237805 Frigidaire Ignitorâ Orifice Assembly
The 316237805 Frigidaire Ignitor Orifice Assembly⣠combines the gas⢠metering orifice âŁand ignitor mounting into a single service component that directly affects ignition timing, flame shapeand burner stability. âCompatibility depends on physicalâ fitorifice size â(for natural gas vs LP),⢠and the type of ignition system installed on the appliance; this assembly is⤠designed for specific Frigidaire range models and can âŁreplace âthe factoryâ part when the part⢠number and mounting geometry match. Technicians should âŁverify the ovenâ or cooktop model number, confirm⢠whether a conversion jet âisâ required for LP serviceand confirm that the ignition method (spark module â¤vs hot surface igniter) isâ consistent with â¤the replacement to avoid mismatched electrical connections or improper gas flow characteristics.
- Safety first: shut âoff gas and electrical⢠power beforeâ disassembly.
- Remove access panel and burner components âto expose the orifice and ignitor.
- Disconnect ignitor⤠wiring,unthread the⤠orifice âassembly,and install the new unit with proper sealing and torque.
- Perform a soap-bubble leak test at⢠the gas â˘joint, restore powerandâ verify ignition sequence and flame stability.
For troubleshooting and validation, âinspect the ignitor element and orifice â¤seat for âerosion, carbon buildupor physical âŁdamage that⣠can cause delayed ignition,⣠weak flamesor⣠intermittent operation;⣠cleaning alone will â˘not⢠correct a â¤burned⤠or cracked ignitor.â Use aâ multimeter to check continuity of âthe⤠ignitor â¤circuit and âcompare âreadings to the appliance â¤service manualand monitor the ignition event: repetitive sparking withoutâ flame indicates a gas delivery orâ orifice sizing issue, while â¤a steady glow â(hot⣠surface) âor a single spark with no flameâ suggests fuel flow or valve â¤problems.If persistent gas odor, âlarge yellow flamesor continuous pilot operation occur after replacement, stop â˘and consult the manufacturer service data or a qualified â¤technician rather than attempting further âadjustments in the field.
