316237805 Frigidaire Ignitor Orifice Assembly is an integrated component used in Frigidaire gas cooking appliances that combines the gas orifice/nozzle and⤠the ignition element into a single serviceable unit. As a mechanical⤠and electrical assembly, it includes the calibrated orifice that âmeters fuel flow at the burner and the ignitor element (either⢠a spark or hot-surface type) that provides the energy to initiate combustion. The part is designed to fit the burner mounting geometry and âgas-train interfaces âŁused â¤on specific frigidaire range and oven models.
Inside the appliance,the ignitor orifice assembly plays two closely related roles: precise fuel metering and reliable ignition.The⣠orifice sets the maximum flow for a given burnerâ or burner bank and therefore establishes the nominal flame size and heat output âfor that circuit,while the ignitor provides the timing and energy needed to igniteâ the gas when the control âŁcalls for heat. functionally it interfaces with the manifold/gas valve, burner âhead and⤠capandâ the appliance control/ignitionâ module or wiring harnessand it must beâ matched to the appliance’sâ gas type and âpressure settings to maintain⣠correct combustion characteristics and safety interlocks.
This article will explain the detailed function of â˘the 316237805 assembly, how to determine compatibility with specific Frigidaire models⣠and fuel types (natural gas vs. LP), common failureâ symptoms to watch for, â¤diagnostic checks a technician can âperformand practical replacement considerations. Topics covered⢠include expected electrical and mechanical measurements, âsigns of orifice or ignitor degradation, steps for safe removal⢠and installationand postâservice verification procedures to confirm proper operation and leak-free installation.

Functional role and thermal/electrical specifications of the ignitor orifice assembly
The 316237805â Frigidaire Ignitor Orifice Assembly is a precision⢠mechanical component that locates and meters âŁthe gas flow to the burner in Frigidaire gas ovens and ranges. It secures the orifice tip in the correct position relative to the ignitor so the gas stream is properly introduced to the ignition source; correct alignment ensures rapid, âconsistent ignition and stable flame geometry. Even though the assembly does not generate electrical power, its geometry and placement âaffect the ignition conditions for hot-surface or spark igniters, âand it must match the applianceSâ fuel type and mounting âinterface to maintain safe operation.
This assembly is â˘manufactured from heat- and corrosion-resistant metals to⣠withstand the high-temperature environment at the burnerâ throat and to resist degradation from combustion byproducts.â The orifice diameter and sealing surface are selected for⢠either natural â¤gas or LP service, so swapping between⣠fuels requires the correct⢠orifice â˘size or a manufacturer conversion kit; incorrect sizing causes⤠weak flames, delayed ignitionor excessive soot. âTypical diagnostic indicators of âa failing orifice assembly include delayed ignition, inconsistent flame appearanceor persistent gas odor at startup, which are symptoms technicians can cross-checkâ by inspecting the orifice for blockage, verifying proper seating, â¤and confirming⣠compatibility with the appliance model.
- Primary functions: gas metering,positional alignment to ignitor,and pressure-tight sealing.
- Material and environment: corrosion-resistant metal sized for⢠burner temperatures and combustion exposure.
- Compatibility: matched to fuel type â(NG vs LP) and specificâ Frigidaire model mounting geometry.
- service notes: blockage, misalignmentor incorrect orifice size causes ignition problems⢠and requires⤠replacement or conversion per manufacturer guidelines.

How the 316237805 Frigidaire Ignitor orificeâ Assembly integrates with burner,⣠ignition,⢠and control systems
The 316237805 â¤Frigidaire Ignitor Orifice Assembly combines a calibrated gas orifice with the ignitor mounting and/or electrode positioning hardware so that gas flow and ignition occur atâ the designed location and rate. installed between⣠the gas control valve and the burner, the assembly âprovides a predictable pressure drop and positions the ignitor relative to burner ports to achieve proper mixture and stable flame propagation. As theâ orifice diameter, seatingand alignment directly affect ignition timing and â˘flame quality, technicians shoudl check for correct orifice size, debrisand âŁsecure mounting when diagnosing weak flames, delayedâ ignition, â˘or flame instability. In systems that use flame rectification or⢠an electrode for sensing,the assembly must also provide⤠a reliable electrical path to the ignition control module.
- Gas metering – calibrated restriction that sets flow at aâ given valve opening
- Ignitor âalignment – âpositions ignitor or electrode relative to burner ports
- Flame sensing compatibility – supports flame rectification or separate sensor arrangements
- Mechanical interface – mounting âtabs, thread sizesand seal surfaces that affect fit
- Electrical interface – connector type and continuity for ignition control
The assembly interfaces mechanically with the control valve and burner, âelectrically withâ the â˘ignition â¤module or electrode circuitand functionallyâ with the appliance’s control logic that times valve opening and spark or glow activation. âŁFor example, a control module that commands a wider valve opening expects the orifice to produce âa corresponding flow rate; â˘substituting an incorrect orifice âwill change heat output and can trigger⢠safety cutouts. During field service, âmeasure or verify orifice size, â¤inspect the electrode gap and⣠insulation, confirm thread and seal compatibility with the valveand test flame-sensing continuity with a voltmeterâ or amp probe. The table below summarizes the â¤primary technical parameters to verify before replacing the assembly.
| Item | description |
|---|---|
| Orifice diameter | Controls gas flow rate and influences flame â˘size/temperature |
| Mounting interface | Thread, flangeand âtab dimensions determining mechanical fit |
| Electrical connector | Type⣠and continuity⢠required for spark/rectification or hot-surface âŁfeed |

Common failure modes, observable symptomsand diagnostic tests for the ignitorâ orifice assembly
The 316237805 â˘Frigidaire Ignitor Orifice âassembly is âŁthe engineered gas metering and mounting component that pairs with the oven/burner â¤ignitor to âestablish theâ correct jet size, alignmentand âsealing for reliableâ ignition. In service it must present the correct orifice diameterâ and concentric alignment toâ the burner port while providing âŁa secure mechanical and gas-tight interface to the⤠valve train. This OEM assemblyâ is designed to match specific Frigidaire model valve pressures and burner geometries; swapping in an⣠orifice with the wrong bore, threador seating angle can produce lean or rich mixtures, unstable combustionor âregulator overwork.⣠In practical terms, compatibility â¤means confirming⣠the part numberâ or the required bore size during appliance model repair â˘or during fuel conversion between natural gas⢠and LP, since a different âorifice size is required âŁfor each fuel type.
- Clogging or partial obstruction – slow light, weak⣠or distorted flameorâ sputtering.
- Enlargedâ or damaged bore – high flames, yellow tipping, soot depositionor backfiring.
- Misalignment / mechanical damage – flame lifting or flame⢠impingement on adjacent components.
- Leak at seat or fittings – detectable gas âodor, âhissing soundor pressure loss at low flows.
- Associated ignitor failures – â˘delayed ignition or âŁrepeated sparking despite correct gas flow (indicates separate ignitor/electrical fault).
Diagnostic tests focus on isolating orifice geometry and flow behavior from the ignitor and valve operation. Start with a visual inspection and magnifiedâ bore check for particles or corrosionand confirm seating âintegrity at low pressure after closing the valve. measure steady-state burner flame characteristics â(length, color, lift) andâ compare against manufacturer flame charts; a manometer acrossâ the valve or a pressure gauge at the regulatorâ will reveal supply or drop issues that mimic orifice faults. Electrical checks on the ignitor circuit (resistance or current draw for glow ignitors) distinguish a no-flame condition caused by insufficient ignitor heating from a fuel delivery problem. For field verification, cleaning the orifice and recheckingâ flame â˘patternor temporarily substituting a known-good OEM assembly, are practical confirmation steps before replacement. always isolateâ fuel and follow safe procedures when performing pressure or â¤leak tests.
| Item | Description |
|---|---|
| Visual / Bore inspection | Look for debris, corrosionor distortion of the bore; a partially blocked orifice reduces flow and alters flame shape. |
| Flame pattern check | Healthy flame: short, blue, stable. Yellow tips, long or lifting flames indicate incorrect âflow or air/fuelâ ratio. |
| Pressure measurement | Use a manometer at the regulator/valve: low supply or excessive drop across the valve suggests system issues⤠beyond the orifice. |
| Ignitor electrical âtest | Measure resistance/currentâ of⣠the ignitor to confirm it reaches rated draw; a weak â¤ignitor can prevent valve openingâ despite correct orifice flow. |
Compatibility, model crossâreferenceand replacement/installation guidelines for the 316237805 frigidaire Ignitor Orifice Assembly
The 316237805 Frigidaire Ignitor Orifice Assembly â¤combines the gas metering orifice and the ignitor mountingâ into a single serviceable unit that controls fuel flow and positions the ignition electrode relative to the burner. Compatibility is determined by mechanical and fluid features rather than model year alone: âverify valve port thread typeorifice bore⣠diameter, mounting boss spacingand ignitor electrode geometry against the original assembly or the manufacturer’s exploded parts list. technicians should crossâreference⤠the part by comparing the physical dimensionsâ and sealing method (threaded vs. pressure fit) and by confirming that the ignitor’s electrical connector and electrode clearance match the appliance’s burner design before⤠ordering a replacement.
Replacement and installation are straightforward when the correct part is confirmed: isolate gas⢠and âelectrical supply, remove access panels to expose the burner valveand note the orientation of the existing assembly before âremoval to preserve alignment. After installing the new assembly, tighten⣠to manufacturer guidance (hand start, then wrench to a snug fit), restore servicesand verify operation with a leak âtest and observation of flame characteristics; a properly seated orifice produces an even, stable flame without⣠delayed ignition. practical checks for successful replacement include ensuring the ignitor electrode isâ centered inâ the flame path, the orifice bore is free of⢠debris, â¤and â¤the burner lights consistently âon the first ignition attempt.
- Service checklist: isolate utilities, confirm mechanical fit, clean mating surfaces, install assembly with correct orientation, perform leak âtest, observe flame quality.
