316536602 âŁFrigidaire Oven Ignitor/Orifice Assembly is a combinedâ ignition and gasâmetering subassembly used inâ Frigidaire gas ovensâ and ranges. As a functional unit â˘it typically âcomprises a hotâsurface ignitorâ element paired with â¤a precisely sized gas âorifice and mounting hardware; the ignitorâ provides the thermal energy required to ignite âmeteredâ gas delivered through the orifice, while the orifice establishes the intended fuel flow to âthe burner.â The⢠part is an⣠electromechanical/combustion component designed for direct installation at the oven burner throat and is treated as âa fieldâreplaceable service item in many models.
Inside the appliance the ignitor/orifice assembly interfaces directly with the oven control, the gas safety (operating) valve, the burner tube and âŁthe appliance wiring harness. âWhen the control âcalls for heat it âenergizesâ the ignitor; as the ignitor heats and its electrical characteristics change, the gas⣠valve is actuatedâ and gas flows through the orifice to the burner where the ignitor âinitiates combustion. Proper interaction between the ignitor, the valve, the orifice âand any â˘flame sensing circuitry isâ critical for predictable ignition timing, stable combustion and âsafe shutoff in the event of a failure.
This article explains the assembly’s function and where it is typically used, âŁdescribes compatibility and identification⤠points a technician shouldâ check,â and â¤outlines common failure symptoms such as delayedâ ignition,â weak or⣠uneven âflameor a complete lack of ignition. It⢠also covers systematic â˘troubleshooting approaches-visual inspection, electrical â˘checks and gasâflow verification-and replacement considerations⤠including correct⤠part matching,⢠handling of the âfragile ignitor elementand basic â¤safety precautions â(removing powerâ and gas before service). The goal is to provide technical context âto help technicians, engineers and appliance owners diagnose issues and make informed service decisions without prescribing â¤detailed procedural steps inâ this introduction.

Function and â¤Role of the Ignitor/Orifice Assembly⤠in Gasâ Flow Regulation and Ignition
The 316536602 âŁFrigidaire Oven Ignitor/Orifice Assembly performs two coordinated functions: the â¤ignitor provides the heat and electrical load necessary to actuate the â¤gas valve, while the orifice physically meters the gasâ delivered to âthe burner. The ignitor is a hot-surface resistive element that must reach a specified temperature âŁand current draw profile so theâ oven’s gas valve senses a proper load and opens; if the ignitor is weak (higher resistance âŁor slow to glow) the valve will not energize or will âdelay gas flow. The orifice âis sized for âŁthe appliance’s design⤠gas type and manifold pressure; incorrect size or a partially blocked orifice changes flow rate and combustion characteristics, producing low flame, yellow tippingorâ longer preignition glow âtimes. Technicians should confirm model â¤compatibility and gas type before replacing â¤the assembly,â and verify electrical⢠connections âand manifold pressure during diagnosis.
- Operational behavior: ignitor must reach target current draw to permit valve opening; âŁorifice sets flow rate for stable combustion.
- Common symptoms: âŁlong glowâ time âŁbefore ignition, weak or yellow⣠flame,â repeated reignition attemptsor gas odor indicating interrupted âignition.
- Service considerations: check wiring,voltage,and orifice cleanliness; use manufacturer-specified orifice sizes forâ natural âgasâ vs.LP service.
From a practical engineering outlook, the ignitorâ and orifice âŁform a matched pair where electrical⢠and fluid⣠characteristics interact: the ignitor’s electrical resistance and warm-up time determine when the gas valve is allowed to openand the orifice size combined â˘with manifold pressure establishes the âmass flow â¤and resulting flame geometry. A marginal⣠ignitor⤠may still glow⢠but not draw⣠sufficient current, creating intermittent ignition that is often misdiagnosed âas a valve fault; conversely, âan oversized orifice with nominal âpressure can cause excessive flow and incomplete combustion. For repairs, replaceâ a failing ignitor rather than adjusting controlsand replace or clean the orifice if flow or flame shape is abnormal; verify replacement â¤parts against the oven’s model numberâ and gas type âŁto ensure safe, consistentâ operation.

How the 316536602 Frigidaire Oven Ignitor/Orifice Assembly â˘Operates within the Oven’s Gas Delivery and Ignition Circuit
The 316536602 Frigidaire Oven Ignitor/orifice â˘Assembly functions as the combined hot-surface âŁignition element and gas metering âcomponent at the burner.⣠When the oven control sends power, the ignitor (a glowâbar type) heats and establishes the electrical conditions required for the safety gas valve to energize; â¤once the valve â˘opens, the orifice portion meters the incoming gas and shapes the jet âŁto produce aâ stable pilot/main burner flame. In practical âterms this means â˘the assembly must be both electrically compatible with the oven’s control âand â¤valve⤠circuit and dimensionally correct âŁfor the burner ports so that the flame burns cleanly and the safety interlocks operate reliably.
- Primary functions: provide heat/current path to actuate the⤠gas valve and meter gas flow for correct flame geometry.
- Typical observable behaviors: steady red glow prior to ignition, immediate âŁfull flame once valve opensand consistent flame height/shape when correctly sized.
- Failure modes and compatibility considerations:⣠weak â˘or no glow, slow ignition,⣠or yellow/tipping flame âindicate âignitor degradation, incorrect⤠orifice âŁsizingor âvalve â˘issues-replace only âwith OEMâequivalent parts or verified compatibles.
| Item | Description |
|---|---|
| Ignitor function | Heats to a glowingâ state to allow the â¤safety gas valve to energize; forms the electrical element of the ignition circuit. |
| Orifice assembly⢠function | Meters gas flow âand establishes the jet geometry that produces the correct burner flame once the valveâ opens. |
For technicians and appliance owners, compatibility checks should include connectorâ type, mounting orientation, âand confirmation that the assembly matches the oven’sâ gas type and pressure requirements; mismatch can cause slow ignition, incomplete combustionor safety âinterlock âfailures.⢠Basic ânon-live diagnostics include visual inspection for a steady glow and âchecking⤠for soot,warping,or obstruction of the orifice; live-current or resistanceâ measurements and any work â˘on the gas valve âŁor electrical circuit â¤should follow âmanufacturer service procedures or be performed by a⤠qualified technician.
Common Failure Symptoms:â Ignition Delays, Flame Irregularitiesand âŁElectrical⤠Load Signatures
The 316536602 âFrigidaire Oven Ignitor/Orifice⣠Assembly combines⢠the â¤hot-surface ignitor and the gas orificeâ into a single⣠service item;â the ignitor must reach a specific âtemperature and draw sufficient â¤electrical current to allow the oven gas safety valve to open, while the orifice meters the correct gas â˘flow and shapes the burner flame. When eitherâ element degrades – a weak ignitor⢠that âheats more slowly or an orifice â˘partially obstructed – the observable behavior will be ignition âdelays, intermittent flames, âorâ unstable flame patterns. Technicians should assessâ bothâ the thermal/electrical performance of the ignitor and the physical condition and sizing âof the orifice,sinceâ replacement of only â˘one⤠subcomponent may not correct âŁcombustion or safety-related symptoms if the other is compromised.
Electrical load âsignatures provide objective evidence of failure: a âhealthy ignitor exhibits⣠a predictable inrush and steady-state current profile as it reaches operating temperature, whereas âa failing unit will âdraw â¤less current, take⣠longer to stabilizeor âshow open/erratic continuity. Practical âdiagnostic actions include a clamp-ammeter measurement âŁof the ignitor circuit during startup, resistance/continuity checks with âŁthe⤠assembly removedand aâ visual inspection of the orifice for carbon, lint,â or deformation. Common service scenarios include an oven that takes substantially longer than normal⣠to light, repeated ignition âŁattempts with audible clicking from the gas valveor a low, liftingor yellow-tinged flame that causes uneven baking; each⤠of these outcomes points to either reduced thermal output from⤠the ignitor or restricted gas flow at the âorifice.
- Delayed ignition or longer warm-up time
- Repeated â¤valve cycling/clicking without steady flame
- weak, liftingor yellow/sooty flame
- Uneven oven temperature or longer-than-expected â˘bake cycles
| Item | Description |
|---|---|
| Electrical check | Measureâ continuity and startup current; look for reduced steady-state current or open circuit. |
| Visual inspection | Inspect ignitor for cracks, glazingor mechanical â¤damage and orifice forâ blockage⣠or deformation. |
| Functional effect | Ignition delay,⤠intermittent flameor poor burner geometry affecting temperature consistency. |
replacement Considerations â¤and Installation: Part Verification, Mounting, Gas Tightnessand Electrical Connections
The â316536602 Frigidaire Oven Ignitor/Orifice Assembly combines âthe âelectrical â˘ignitor element and the gas âorifice into a single service⢠item that â˘both â¤initiates ignition and meters â¤fuel flow to the burner. Before âŁinstalling, verifyâ the replacement matches⣠the oven model, gas type (natural gas or LP), âand orifice size specified in the service documentation; differences in orifice diameter change flame height and combustion âcharacteristics. Technically, the ignitor must draw sufficient âcurrentâ to allow the safety valve to open; an âignitor that âŁglows but draws insufficient current will prevent valve actuation even ifâ continuityâ is present. Use a multimeter and, when âsafe and appropriate, an âammeter during an ignition attempt to confirm operational behavior rather than relying on visual glow alone.
- Confirm âpart number and gas type compatibility⢠against the oven’s model/service â¤sheet.
- Inspect mounting surfaces, gaskets,â and fastenersâ for damage or distortion prior to assembly.
- Measure ignitorâ resistance and, âif possible, monitored âcurrent during ignition to âŁverify performance.
- Align the orifice with the burner port and tightenâ fasteners per the manufacturer procedure;â avoid over-tightening.
- Perform aâ gas leak check at low pressure after assembly using a calibrated detector or approved soap solution.
Mounting and sealing affect both gas tightness⤠and flame geometry: ensure the mating surface isâ flat and the gasket or sealing method âspecified â¤by the manufacturer âŁis⤠usedâ to prevent leaks or⢠partial obstruction⤠of the âŁorifice. Do not use pipe thread compound on the orifice or internal⢠gas passages. for electrical connections, use the correct insulated connectors, âŁmaintain secure crimps or splicesandâ route wiringâ away from âŁhot components to prevent insulation degradation; a looseâ or intermittent connector commonly produces intermittent ignition faults. Afterâ installation, verifyâ proper flame â¤characteristics (steady,â blueand uniform) and perform a final leak⤠test; if the flame⢠is weak, lifts, âor is yellow, re-check orifice size, gas pressureand mounting alignment ârather than assuming an electrical fault.
| Item | Description |
|---|---|
| Ignitor verification | Measure resistance and monitored current⢠during ignition attempt; compare â˘to⢠service data. |
| Orifice compatibility | Confirm size and gas type (natural/LP) from model/service documentation. |
| Mounting | Flat mating âŁsurface, correct⢠gasket, manufacturer-specified âŁfastener torque and alignment. |
| Gas tightness | Leak check with âelectronic detector or approved soapâ solution at operating pressure. |
| Electricalâ connections | Insulated,secure connectors; routing⣠away from âŁheat; check for proper âgrounding/continuity. |
Q&A
What â˘is the⢠316536602 Frigidaire Oven Ignitor/Orifice Assembly and what â˘does it do?
The 316536602 âis an OEM Frigidaire replacement assembly that combines theâ hot-surface oven ignitor and the gas orifice/nozzle for the bake burner.The ignitor heats and reaches a temperature sufficient to⣠cause the oven’s gas safety valveâ to open;â the orifice meters â¤the gas flow into the âŁburner ports so a proper flame is produced. Together they enable safeâ and âreliable ignition of the oven’s bake burner.
How do âI know âif the ignitor/orifice assembly is bad?
Common symptoms include: âoven not lighting at all, very long preheat times, weak or yellow/tipped â¤flameor âcyclical on/off âheating.A failing hot-surface ignitor may glow dimlyâ or not at allor â˘it may glow but not draw⣠enough current to open the gas valve.⤠A clogged orifice can cause â˘an uneven or weak flame. Always verify visually and with âŁelectrical tests beforeâ replacing.
Can I test the ignitor myself and âwhat⢠should I measure?
Yes-after disconnecting â˘power and ensuring the gas supply is⣠off â˘and the appliance is safe⢠to work on. âUse âŁa âmultimeter to check for continuity/resistance â˘(many hot-surface ignitors show tens of⤠ohms, but values vary). The most reliable test â¤is an amp âdraw test⢠with a clamp meter when theâ oven calls for heat: typical hot-surface oven ignitors generally draw roughly 3.0-3.6 A at 120 V; a considerably⤠lower amp draw usually indicates the ignitor is weak and should be replaced.Compare readings to⣠the manufacturer spec for exact values.
Is installation something a âhomeownerâ can âŁdoand what safety steps should âI follow?
If you are cozy working on âŁappliances, you can replace the assembly, but you must turn off electrical power to the range⤠(unplug or⣠switch off breaker) and shut off the gas supply before starting. Work in a⢠well-ventilated area, avoid damaging the ignitor’s ceramicand â˘follow the service manual for â˘your model. After installation and gas reconnection, check for âŁgas leaks (soap solution or a âgas leak â˘detector) âŁand light the⤠oven to verify operation. If you are ânot confident with gas⣠or electrical work,hire a qualified technician.
Do I need to replace the â˘whole assembly â¤or can I replace just the ignitor âor just the â˘orifice?
Thatâ depends on the failure â¤mode â˘and what parts⤠are available. If âthe ignitor fails electrically but the orifice is intact and clean, you can sometimes replaceâ just âthe âŁignitor. If the orifice is clogged, damagedor sold as a combined assembly for your model (many OEM parts come asâ an assembly), it’s common and frequently âenough recommended to replace the entire assembly to ensure proper fit and⣠performance. Check parts diagrams for â¤your model andâ the part⢠availability.
What tools and materials⢠will I âneed â¤to replace the⣠part?
typical tools: nut drivers or screwdrivers âto remove access panelsâ and⣠mounting⤠screws, a socket set, âpliers, â˘aâ multimeter âŁand/or clamp ammeter⤠for testingand⤠needle-nose â¤pliers âfor âwire âconnectors. You may also want a smallâ brushâ or compressed air to cleanâ the burner area. For gas connections,use only proper gas-rated fittings/sealants if any threaded connection must be resealed; do not⢠use ordinary Teflon⢠tapeâ on gas fittings unless it’s gas-rated and applied per instructions.â If in doubt, call a pro for the â¤gas connection.
How â¤long does a Frigidaire ignitor/orifice assembly typically last and⤠can maintenance extend its life?
Lifespan varies with usage and surroundings;â many last several years to a decade. Heavy use, moistureor grease âbuildup âcan shorten life. Keeping â¤theâ oven clean (especially the burner and orifice â˘area), avoiding spills thatâ coat the âignitorand periodic âinspection can help. â¤However, hot-surface âignitors gradually â˘degrade âand âwill⣠eventually need replacement even with good care.
How do I confirm âŁcompatibility of âpart 316536602 âŁwith my oven model?
Check your oven’s model number (usually on a tag inside the door⣠frame or storage drawerâ area) and compare it⢠to the Frigidaire parts list or âŁthe⢠part seller’sâ compatibility lookup. Many OEM part suppliers and Frigidaire’s website allow you to enter your model number âŁto confirm compatibility. If you’re unsure, provide the appliance model and serial number to a parts dealer or technician â¤for⢠confirmation before buying.
