316237805 Frigidaire Ignitor Orifice⣠Assembly is a serviceable â¤combustion component used in Frigidaire gas cookingâ appliances; it is indeed the mechanical and functional interface that âlocates the ignition device relative âŁto the burner and houses the gas orifice that metersâ fuel to the burner port. In practical terms the assembly typically consists of â¤a metal mounting plate or bracket, an orifice insert sizedâ to control gas flow (and therefore burner BTU)and a provision to secure the electrical ignitor â¤(spark orâ hot surface) so that flame initiation occurs consistently at the correctâ location.
Inside theâ appliance âthe âignitor orifice assembly⢠interacts directly with the gas valve and regulator, the burner headand the ignition control circuitry or module.Proper alignment and sealing of âthe orifice and ignitor affect flow⢠rate,flame geometry,ignition reliability,and flame sensing feedback; misalignment,blockage,or incorrect orifice sizing âŁcan⣠produce delayed âignition,unstable or sooting flames,or false âflame-failâ indications.⣠From a systems outlook the part is important âŁbecause itâ links the fluid (gas)â delivery path to the electrical ignition and flame-detection systems, so its condition and specification influence combustion performance and âappliance safety.
In the following article readers will find a â¤technical â¤overview ofâ the 316237805 assembly’s function and common design variants,guidance on compatibility and how â˘to verify the correct orifice size and orientation for a given model,typical failure symptoms âŁto⤠recognize in the⤠field,diagnostic and troubleshooting steps â¤to isolateâ ignitor versusâ gas-flow issues,and practical replacement considerations such⣠asâ part verification,mounting and sealing practices,and⣠safety checks to âŁperform after service. The coverage is intended to support technicians, engineersand educated appliance âowners âin making informed⣠diagnostic and repair âŁdecisions without prescribing⤠procedures beyond standard safety and regulatory requirements.

Function and Role of the Ignitor Orifice Assembly in Frigidaire Gas Appliances
The 316237805 Frigidaire Ignitor Orifice Assembly meters⣠and regulates the gas flow delivered âto the ignitor and burner assembly,ensuringâ the correct volumetric flow for â˘reliableâ ignition. As âa precision orifice, â¤its internal diameter and âseating⢠determine âthe gas velocity and pressure drop between the valve outlet and the ignitor port; this interaction controls initialâ flame size and⤠stability during⤠the pilot/ignition sequence. In practical service scenarios, a partially blocked orifice will present as delayedâ ignition, soft or⢠yellow-tipped âflamesorâ repeated safety valve lockouts, while an undersized or âworn orifice can reduce burner performance despite a⣠functioningâ ignitor âand valve.
- Metersâ gas to provide⤠repeatable âŁignitionâ pulse and properâ flame geometry.
- Affects⣠ignition timing and flameâ stability through fixed flowâ restriction.
- Compatibility depends on valve outlet pressure andâ manifold fittings; replace onyl with specified part to maintain design flow.
- Common failure modes: contamination, corrosionand mechanical wear at the seat orâ threads.
Technically, the â¤assembly operates as â˘a calibrated restriction upstream of the burner; flow â¤is persistent by the orifice â˘diameter and upstream â¤pressure, so field checks should include pressure âverification and visual inspection rather than relying solely onâ continuity or âignitor â¤resistanceâ measurements. Installation orientation⤠and proper sealing are necessary to avoid leaks â˘or altered flow characteristics; technicians typically verify âcorrect â˘behavior âŁby observing⣠ignition sequence, measuring⢠static manifold pressureand confirming flame appearance⣠under steady-state âconditions. For replacement, matching the â¤part number,⢠thread type and seatâ geometry preserves designed pressure/flow relationships and avoids iterative troubleshooting caused⤠by nonâequivalent components.

How the 316237805 Frigidaireâ Ignitor Orifice Assembly⣠Works Inside the âAppliance
The 316237805 frigidaire Ignitor Orifice Assembly is a precision âgas metering âand âmounting subassembly âthat⢠positions a calibrated orifice in âfront of the appliance’s ignition source âso that a controlled gas jetâ reaches the ignitor. In operation the valve supplies upstream pressure, the orifice creates a predictable pressure drop and flow rateand the⤠ignitor (spark or hot-surface type depending on model) provides the energy to light that metered âstream. Correct fit and alignment inside the burner box or manifold are essential: if the orificeâ is recessed, rotatedor the retaining âbracket is loose âŁtheâ gas/air mixture and flame impingement on the ignitor âŁwill change, leading to inconsistentâ ignition or flame geometry. This âassembly âis intended for Frigidaire gas ranges/ovens that âreference âŁpart number 316237805 in OEM parts lists andâ is⢠engineered to match the valve outlet and ignitor spacing used by those models.
Behavioral effects âof the assembly âare âprimarily seen as ignitionâ timing,flame shape,and stability. A properly functioning â¤orifice âŁassembly produces an even, steady flame immediatelyâ after the ignitor energizes; common faults include delayed ignition, intermittent extinguishment, yellow tipping or sooting⢠(indicating an overly rich â¤mixture or partialâ blockage)and persistent gas odorâ prior⤠to âignition. Technically, troubleshooting requires inspection for carbonâ or debris in the orifice, verification of manifold pressureand confirmation that the ignitor reaches its⤠required temperature or spark energy-replacement should be⤠performed â˘when the orifice shows physical âdamage, corrosionor when corrective â¤cleaning âdoes not restore normal flame behavior. For service technicians, consider orifice wear or incorrect orifice size during fuel-type conversions (natural gasâ â LP) and confirm compatibility â˘with the appliance’s service manual before âinstalling âthe 316237805 assembly.
- Primary functions: gas metering,⢠secure positioning⤠relative⤠to â¤ignitorand maintaining repeatable âflow characteristics.
- Common âsymptoms of malfunction: delayed ignition,weak or unstable flame,yellow/sooty âflame,and gas odorâ beforeâ ignition.
- Service checks: visual orifice inspection, manifold â˘pressure check, âŁand ignitor performance test.

|---|---|
| Orifice | Calibratedâ aperture that meters gasâ flow; critical to âcorrect air/fuel ratio and flame size. |
| Mounting interface | Bracket andâ seal that position the orificeâ in relation to the ignitor and prevent leaks. |
| Typical faults | Blockage, misalignment, corrosionor incorrect orifice size for⢠the fuel type. |
Common âŁFailure Symptoms and Diagnostic Indicators for the Ignitor Orifice Assembly
The 316237805 Frigidaire Ignitor Orifice assembly is a âŁsmall metering and mounting component that controls the local gas flow and directs the gas/air mixture to the ignition pointâ at aâ burner. In operation it must present the correct orifice diameter and a clean discharge path so the ignitor⣠(spark or hot-surface) can reliably light the gas; variations in orifice size,partial blockage,or âŁpoor sealing changeâ manifold pressure at the burner and alter flame shape and â¤stability.⣠This âŁassembly is âcompatible with Frigidaire âgas ranges and ovens that use separate orifice fittings for each⣠burner;â though, correct interchange requires matching⣠the â˘orifice size and mounting interface to the appliance service specification ratherâ than assuming⤠visual similarity between partsâ from different models.
Technically,failures of the â¤ignitor orifice assembly âmanifest as⢠changes in ignition behavior⤠and flame⣠characteristics that a technician can observe and measure. Common diagnostic indicators include delayed or repeated sparking with no light, weak or lifting flames, sooting or yellow tipping at the âburnerand the presence of a gas odor priorâ to ignition. Because thes⤠symptoms can also â¤result from a â¤faultyâ ignitor, â˘bad wiringor âan out-of-spec gas âvalve, an effective diagnosis combines visual inspection (clogging, corrosion, misalignment), â¤functional⤠checks⤠(ignitor continuity and voltage âŁduring spark or glow), âand âsimple operational tests such as swapping a â¤known-goodâ orifice or measuring â˘flame stability after â˘cleaning. practical troubleshooting⢠steps include removing the burner cap⣠to inspect the orifice, blowing or⣠using a âsolvent-safe âprobe to clear â¤deposits, verifying electrode gap and positionand confirming that âpressureâ and â˘valve operation âmeet the appliance’s service data.
- Repeated sparking with no ignition – possible orifice⣠clog⢠or⤠restricted gas flow
- Weak, âŁliftingor yellow flames â˘- incorrect orifice size, â¤partial blockage, â˘or air/gas mixture imbalance
- Intermittent ignitionâ that resolves â¤after cleaningâ – contamination or corrosion in the âŁorifice passage
| Item | Description |
|---|---|
| Delayed ignition | Often caused byâ partial orifice blockageâ or low supply pressure; check orifice and manifold pressure. |
| Yellow flame or soot | Indicates rich mixture⢠or poor âmixing – inspect orifice size and burner ports for obstruction. |
| Intermittent operation | Could be âorifice⤠contamination, â˘loose mountingor âupstream component failure (valve/wiring). |
Compatibility, Replacement Considerations, Installationâ Best Practicesand Troubleshooting Proceduresâ for 316237805
the 316237805â Frigidaire Ignitor Orifice Assembly âŁcombines⣠the âgas metering orifice and the âignitor⤠mounting into a single service â˘item that⤠controls the âlocal fuel flowâ and positions the â˘ignition element relative to the burner port. âŁIts primary function is to present â¤a precisely sized orifice toâ the âvalve outlet so âthe appliance receives the designed BTU⢠input and â˘to âprovide⣠a rigid, repeatable⣠mount for the ignitor â¤so âŁspark or glow â˘ignition is consistent. Compatibility depends on physical dimensions (flange shape, thread sizeand orifice drill diameter), the valve outlet geometryand the intended gas type (natural or LP). Confirm compatibility âby comparing physical measurements âand⤠OEM â˘cross-reference numbers rather than relying solely on appliance model ânamesand note that orifice size andâ thread form âmust match the supply valve to âŁavoid pressure drop or leakage issues.
Replacement and â˘installation require⤠both mechanical and electrical checks: shut off gas and âŁpower, remove the old assembly,â clean the valve⣠face and sealing surfaces, fit the new orifice assembly with the correct âŁgasket, âtorque fasteners to theâ manufacturer’s âŁrecommendation, then perform a leak-test before restoring normal â¤operation. Troubleshooting â˘after installation âŁtypically follows a short list of observable symptoms and targeted verifications-weak or no flame⤠can indicate a⣠clogged orifice, wrong orificeâ size, low regulator pressureor a⤠failed ignitor; delayed⣠ignition⢠or continuous clicking suggests poor ignitor heating or incorrect electrical supply. Technicians â˘should measure ignitorâ resistance with⢠a multimeter, verify âŁsupply voltage to the ignitor circuit during a light attempt, inspect for carbon/debris in the⣠orificeand confirm flame characteristicsâ (color and lift) against expected⤠parameters. â˘Practical checks include confirming theâ orifice âdrill code when converting gas âŁtypes and re-checking seals and â¤torque after initial boil-in⢠orâ thermal cycling.
- Common â˘symptoms to âcheck: weak flame, delayed ignition, âburner outâ after ignition, continuous clicking, gas âodor after âshutdown.
- Quick verifications: visual orifice obstruction, ignitor continuity and voltage, gasket integrity, leak-test at the valve/orifice joint.
