316536623 Frigidaire Ignitor/Orifice Assembly is a combined ignition and gas metering component used in Frigidaire gasâ cooking appliances. The assembly typically integrates anâ ignitor element (either an electrode for spark⣠ignition or a hot-surface ignitor depending on the âmodel) with a fixed orifice that meters gas flow too the burner; together these parts control the initiation and rate of fuel âdelivery at the burner port.As a replaceable service item, the assembly is a discrete mechanical/electrical component intended to fit specific appliance models and mounting interfaces.
Inside the appliance, the ignitor/orifice assembly participates directly âŁin the ignition â˘sequence and combustion control. It interfaces with the burner head, the oven/range manifold and gas valve,⢠and the appliance’s control and safety⢠circuits (ignition module, spark âgenerator, flame â¤sensing or flame rectification⢠systemsand any associated thermostats or safety valves). Proper orifice sizing⢠and ignitor performance determine delivered fuel flow, air/fuel mixture characteristics at the burner, ignition âtimingand⤠flame stability; conversely, faults in the assembly can produce ignition failures, delayed lighting, incomplete combustionor safety interlocks preventing operation.
This article will explain the assembly’s intended function and the technical parameters technicians and engineers should consider,⢠how to verify modelâ compatibility andâ correct âorifice⤠sizing for natural gas versus LP conversions, common failure symptoms (no ignition,â continuous sparking, yellow or lifting flame, soot, gas odor), â¤and practical troubleshootingâ steps such as visual inspection, âŁcontinuity and voltage checks on the ignitor circuit, verification of manifold pressure and orifice conditionand leak testing after service. It will also cover replacement considerationsâ including correctâ part matching, connector and mounting alignment, sealing and torque practicesand recommended verification tests post-installation to ensure safe, reliable operation.

Function and Role âof the Ignitor/Orifice Assembly in Burner Operation
The 316536623 Frigidaire Ignitor/Orifice Assembly combinesâ a high-voltage spark element and a âprecision gas orifice into a single serviceable unit that both initiates combustion and meters⢠the fuel delivered to the burner. The spark electrode produces⣠a controlled arc across a â¤small gap to ignite âŁthe gas while the orifice provides a calibrated restriction that determines volumetric flow and, thus, the burner’s â¤heat output and flame shape. âŁcorrect seating, thread engagementand alignment with the burner cap areâ required â¤to maintain âconsistent ignition timing and stable flames; deviations from âOEM geometry or using â˘the wrong orifice âsize for âŁthe fuel type will change combustion characteristics and âŁcan cause âdelayed ignition, continuousâ sparkingor sooting.
In practical service, technicians use the assembly’s behavior to distinguish âbetween electrical and âfuel-delivery faults: repeated âsparking with⢠no flame generally implicates a â˘blocked⤠orifice, incorrect⢠orifice sizingor misaligned burner cap, while a weak or yellow-tipped flame indicates an over-rich â¤mixture or â¤low manifold pressure.â When replacing this assembly, match the part and fuel type â˘(natural gas versus LP) and verify electrode gap, leak-tight orifice seatingand absence ofâ debris in the port. Common diagnostic â˘checks include visual flame inspection, leak testing at the orifice connectionand confirming secure âmounting; improper replacementâ can change nominal BTU output and impair âsafe operation.
- Typical observable behaviors: delayed ignition, repeated sparking, â˘yellow â˘flame orâ sootand reduced flame height.
- Quick checks: electrode gap and alignment, â˘orifice clear of deposits, â˘andâ correct orifice for fuel type.
- Compatibility concern: thread typeâ and orifice sizing must⤠match the appliance’s valve/manifold and fuel specification.

How the 316536623 Frigidaire Ignitor/Orifice Assembly Works Inside the Appliance
the 316536623 Frigidaire Ignitor/Orifice Assembly is an integrated field-replaceable unit that combines a hot-surface ignitor with the gas orifice that meters fuel to a burner. in typical operation the ignitor element heats to âŁa visibleâ orangeâ glow,⤠which both provides a hot surface to ignite the gas andâ signals the controlâ board that the ignition⢠sequence has progressed; when the ignitor reaches its operating temperature theâ gas valve is energized and âfuel flows through the orifice were the hot surfaceâ initiates combustion. â˘The orifice aperture and threadâ pattern are matched to specific Frigidaire burner and valve assemblies, so âcorrect gas type (natural gas or LP)â and mounting orientation⣠must be confirmed before installation to ensure proper flame shape andâ heat output.
Functionally, the assembly behaves asâ both a timing and flow element: âthe ignitor determines âŁhow long the control will wait before it either⤠opensâ the⤠gas valve or registers an ignition failure, while the orifice determines the fuel flow rate and therefore the resulting flame size and stability. Practical troubleshooting includes observing the ignition cycle (long glow without flame indicates⤠possible orifice blockage or valve failure), checking⤠electrical continuity and connector integrity for the ignitorand verifying the orifice is the correct specification for the appliance â˘model being serviced. do not bypass safety â˘interlocks; instead replace âtheâ assembly with a correctly specified unit and verify performance⣠by observing consistent ignition across a representative run cycle.
- Symptoms indicating assembly issues: prolonged glow without ignition,weak or yellow flame,or âintermittent ignition.
- Compatibility checks: confirm gas type (Natural vs LP), mounting flangeand connector style⤠before âordering replacement.
- Diagnosticâ steps: â¤inspect â¤and clean the orifice,verify ignitor continuity andâ secure electrical connections,then observe normal ignition âtiming and flame stability.

Common Failure Symptoms and Diagnostic Indicators⢠for the Ignitor/Orifice Assembly
The⢠316536623 Frigidaire Ignitor/Orifice Assembly combines the ignition electrode â¤and gas orifice into âa single⤠serviceable âunit that controls spark⣠generation and fuel delivery at the burner. Functionally, the ignitor provides the high-voltage spark orâ hot⢠surface necessary to ignite âthe gas delivered through the orifice; failures can arise âfrom âelectrode erosion, carbon tracking, cracked ceramic insulatorsor debris restricting the orifice. Compatibility is persistent by the OEM part number and mounting/connector geometry-this assembly is intended to replace⣠the corresponding original component in specified Frigidaire ranges and ovensand should be matched to the appliance service manual to ensure correct gas flow characteristics andâ electrical connections. Practical examples of common behavior includeâ continuous clicking with⢠no ignition (indicating a weak or absent⢠spark) and a lazy, yellow or intermittent flame (suggesting a restricted orifice or partial spark contact).
- Repeated clicking/no flame during ignition cycle
- Delayed ignition or ghostâ flames that⣠appear after multiple attempts
- Irregular flame shape or yellow tipping indicating partial combustion
- Visible electrode erosion, cracked ceramic, â˘or accumulated carbon
- Smell âof âgas without ignition – stop testing and ventilate immediately
| Item | Description |
|---|---|
| Ignitor continuity â¤test | Measure continuity across theâ ignitor terminals with a multimeter; an open circuit indicates a failed âignitor element orâ broken lead. |
| Spark presence | Observe ignition âcycle for a âconsistent, strong spark at the electrode; absentâ or weak sparking points to electrode, module, âor wiring faults. |
| Orifice inspection | Remove and visually inspect the orifice for debris, corrosionor deformation; restricted flow produces weak or unstableâ flames and slow ignition. |
Diagnostic indicators shouldâ be correlated: an open ignitor test combined with no spark points âto ignitor failure,while a present spark but poor flame typically implicates âtheâ orifice or gas supply.For fieldâ diagnostics, verify âŁsupply voltage and control board output to ârule out upstream electrical faults⣠before replacing the assemblyand use a scopes or voltage meter to confirm ignition module pulses if available. âŁAlways follow⣠safe procedures-shut off gas and power before disassembly, âventilateâ if gas is presentand consultâ the appliance’s âwiring â˘diagrams and service specifications for electrode gap and mounting orientation when âinstalling a replacement 316536623 frigidaire ignitor/Orifice Assembly.
Replacementâ Considerations âand Step-by-Step Installation procedures â˘for the Ignitor/Orifice Assembly
The 316536623 Frigidaire Ignitor/Orifice Assembly âcombines the spark/electrode ignition element with a precisely sized gas orifice âto control âŁburner fuel flow and establish reliable âignition.Functionally, the orifice determines volumetric gas delivery for a⣠given pressure and the ignitor/electrode provides the high-voltageâ spark at the correct location relative to⢠the âorifice so the mixture lights consistently; misalignment, a fouled orifice,⣠or degraded electrode ceramics will produce⢠delayed ignition, repeated sparkingor weak flame. Compatibility is aâ function of appliance model and gas type: the assembly must match âthe range’s burners and be specifiedâ for natural gas or propane/LPand orientation of the electrode and⣠sealing gasket must âmatch the original to preserve flame â¤shape and prevent leaks. Technicians â¤should verify the appliance model⢠plate and service manual before⢠ordering âŁor installing this partand treat a repeated misfire after cleaning as an indicator that the integrated âignitor/orifice may need⣠replacement rather âthan component-level repairs alone.
Replacement requires safe isolation of the appliance and careful attentionâ to mechanical and electrical fit. Before âstarting,⢠shut off the gas supply and electrical power, remove burner grates and caps, âŁand noteâ the original assembly orientation and wiring. During installation, âconfirm the replacement â¤orifice size matches the gas type and that the ignitor electrode is âŁpositioned and insulated as the original; a visible sparkâ at the orifice and a stable, blue-centered flame are the functional acceptance criteria. After reassembly, restore power and gas and performâ an audible and soapy-water leak check at the âŁconnection;â if flame lifts, rollsor the ignitor continues to spark after ignition, re-inspect orifice cleanliness, electrode⣠gap/positionand venting. Practicalâ installation steps âŁare summarized below for reference.
- Power and gasâ off; remove grates, burner capsand access â˘panels.
- Disconnect ignitor wiring â¤harness,remove âmounting screws,and extract the old assembly.
- Inspect burner ports and orifice for debris; replace if â˘clogged or damaged.
- Install new assembly in the original âorientation, secure mountingand reconnect wiring.
- Restore âgas and power, verify spark and ignition, then perform a leak â¤test and observe flame quality.

Q&A
What is the 316536623 Frigidaire Ignitor/orifice Assembly?
The 316536623 is anâ OEM replacement assembly used on some Frigidaire â¤gas ranges/ovensâ that combines the oven burner ignitor and the gas orifice/mounting hardware. âThe ignitor provides the heat or spark to â˘ignite gas, while the orifice controls the gas flow into the burner. Together they allow proper ignition and stable burnerâ flame.
Howâ do I know if this is the correct part for my Frigidaire range or oven?
Confirm compatibility by matching the appliance model number⤠(found on the tag inside the oven door, behind the kick âpanelor on the back of the appliance) with the part listing from⢠Frigidaire or an authorizedâ parts dealer. You can also compare the physical appearance and connectorâ type â˘of the âexisting assembly to pictures in the parts catalog. If in doubt,provide the appliance model number to the parts supplier to verify fit.
what symptoms indicateâ the ignitor/orifice assembly is failing?
Common signs of a failing assembly include: the oven burner âwill not light or has a long⢠delay before ignition; weak or intermittent flame; oven âtakes excessively long to reach set â˘temperature; visible damage or cracking on the ignitor; or the ignitor does⣠not glow when⢠the⢠burner is âturned on.If you hear the control trying to light⣠but gas is not igniting,the ignitor/orifice assembly is a âlikely culprit.
Can I test the ignitor to confirm it’s badand how?
You can perform a few checks:â visually inspect for cracks or a broken element; test for electrical continuity with a multimeter (an open circuit indicates failure); and⣠for technicians, measure the ignitor current with a clamp ammeter during a light cycle-many working hot-surface ignitors draw significant âŁcurrent when operating. Always disconnect power âŁand follow safe testing procedures. If you are unsure how toâ perform these tests safely, contact a qualified technician.
How do I safely replace the 316536623 assembly?
Basic safety steps: disconnect electrical power to the appliance and shut off the gas supply before starting. Remove the oven or rear â¤access panel to reach the assembly,disconnect electrical⣠connectors,unboltâ the mounting⢠hardware,and remove the old assembly. Install the new part in the same orientation, âtighten fasteners, reconnect wiring, restore gas and â˘power, then perform a gas leak check and test ignition. If you are not comfortable working â˘with gas or mains electricity,⣠hire a licensed appliance technician.
What tools are typically needed for replacement?
commonâ tools: Phillips and flathead screwdrivers, nut drivers or âŁa socket set, needle-nose pliers, adjustable wrench, multimeter â(for continuity checks)and a gas leak detection solution or â˘soapy⣠water for checking connections.A clamp ammeter is useful for measuring ignitor current if doing advanced diagnostics.
After replacing the assembly the oven still won’t light – what should I check next?
If a new ignitor/orifice assembly â˘doesn’t fix the problem,⤠check the gas âsupply and shutoff valve, the⣠gas regulator and pressure, âŁthe gas safety/solenoid valve, wiring harness and control⤠board for voltage â¤to the ignitorand â˘any safety interlocks or thermostats. Faulty wiring or a defective gas valve/controls are common causes when the âŁignitor itself is known-good. At that point âconsult a âŁqualified technician for live-voltage diagnostics and gas valve testing.
How long does⤠the ignitor/orifice assembly last and isâ it worth âŁrepairing or replacing?
Service life varies with usage and â¤operating conditions; many ignitors last several years but can fail after heavy use orâ thermal â¤cycling.Because the ignitor and orifice are relatively inexpensive compared with major âcomponents, replacing a failed âŁassembly is generally cost-effective. Always use âOEM or âŁequivalent parts and follow properâ installation and⤠leak-testing procedures to ensure safe operation.
