The 316536602 Frigidaire Oven Ignitor/Orifice assembly is âa â¤combined⣠ignition andâ gas â˘metering component used in Frigidaire gas ovens and ranges. As an assembly it âtypically includes a hot-surface or âglow âignitor element⢠alongside â˘a fixed gas orifice or nozzle and mounting hardware; togetherâ these parts initiate combustion⣠at the bake burner âand control the initial gas âflow rate to â¤theâ burner head. The assembly is a field-replaceable service part and is specified by mechanical fit, electrical characteristics of the ignitorandâ the orifice size that matches the appliance’s burner and gas type.
Inside the appliance the ignitor/orificeâ assembly interacts directly with â˘the oven’s gas â˘valve, burner tubeand the â¤control system that commands bake or broil cycles. When the control calls for heat the ignitor element heats to a specified temperature,drawing current âthat âallows the safety gas valve to⣠open and the orifice to deliver the metered gas to the burner; prosperous âignition depends on âboth sufficient ignitor current and âthe correct orifice âŁopening for⢠the appliance’s rated gas pressure. The component is typically mounted at the oven floor or⢠rear â¤burner tube, âand its correct operation is important for reliable ignition, âproper flame characteristics, steady temperature control,⣠and safe exhaust of â˘combustion products.
In this article readers willâ find a technical overview âof the 316536602 assembly’s function and construction, guidance on compatibility and identification, common failure symptoms to recognize (such as extended glow â˘time, no âignition, weak or sooty flameand uneven oven temperature), step-by-step âtroubleshooting checks to isolate ignitor,⤠valveand supply⤠issues, plus practical â¤replacement considerations including electrical and mechanical fit, â˘orifice sizing for gasâ type, leak testingand safety precautions for working on gas appliances. The focus âis on diagnostics and service-relevant details that help technicians, engineersand appliance owners make informed repair or replacement decisions.

Function and Role of⣠the Oven Ignitor and Gas Orifice in Combustion Control
The 316536602â Frigidaire Oven âIgnitor/Orifice Assembly combines⤠a hot-surface ignitor and a precisely sized gas orifice to control âthe start and stability of combustion in the oven âŁburner. The ignitor functions as the primary ignition source: when⤠energized it heats to a glowing temperature that allows the oven’s âgas safety valve to open and the â˘gas toâ flow; if the ignitor is weak or slow to heat the valve willâ not âŁopen⤠or⢠the burner will â˘light intermittently. The orifice downstream of the valve meters gas volume to match manifold pressure and burner geometry, establishing the intended air-fuel ratio for efficient,⤠stable flame.Together these two components â¤determine ignition timing, flame shapeand the safe operation envelope for the burner assembly.
- Common failure symptoms: delayed ignition, long glow time before ignition, low or unstable flameorâ flame lifting/sooting â˘that indicate a weak ignitor⤠or incorrectly sized âorifice.
- Compatibility checks: match âmounting, electrical connector type and required⤠ignitor current or resistance, plus confirm orifice size⣠corresponds to the installed gas type (natural vs. LP).
- Diagnostic steps: visually inspect flameâ color and height,measure ignitor continuity/resistance and warm-up behavior,and verify manifold pressure before changing orifice âŁsizing.
When replacing âor troubleshooting âthe assembly, use parts that meet the original â¤specifications for both the ignition element and the orifice to preserve combustion control and safety interlocks; swapping in an ignitor âwithâ different electrical characteristics can prevent⤠the gas valve from⢠operating correctly, while an⣠incorrect orifice will alter burner temperature and emissions. Technicians typically âconfirm proper function by observing⣠a consistent, blueâ flame across⢠the burner and verifying that âŁthe⣠ignitor reaches operatingâ glow within the expected time window; if⢠measurements are required, compare the ignitor’s resistance âŁand warm current to the manufacturer’s service data and ensure the orifice size matches the âappliance conversion label or documentation.

how the 316536602 Frigidaire Oven Ignitor/Orifice Assembly Operates âWithin the Appliance’s Gas and Electrical Systems
The 316536602 Frigidaire Oven Ignitor/Orifice Assembly integrates a resistive hotâsurface ignitor with⤠a matched gas orifice to start and regulate combustion âat the oven burner.Electrically, the ignitor is fed from the âŁappliance mains (typically 120 VAC on North American units) and heats to a visible glow; when the element reaches its designed operating temperature it satisfies the oven’s control circuit and allows the gas valve to open. The orifice portion meters the volumetric gas flow to the burner â˘ports so the delivered fuel matches the burner geometry and the appliance’s intended âgas type⢠(natural gas or LP). In practice, âthe timing between the ignitor reaching temperature and the valve opening determines ignition delay and flame shape,⢠so proper matching of ignitor characteristics and orifice size is âŁrequired for reliable ignition and stable combustion.
The assembly’s behavior⣠affects both⤠electrical and gas subsystems: a âhigherâresistance or aging ignitor will take longer to glow and can prevent âthe⤠control from enabling âthe valve,⢠while an incorrect orifice will produce low, unstableor overly large flames and may cause the safety system to shut down the gas flow. Technicians should check ignitor heatâup visually and measure resistance/continuity, â˘verify the orifice size against the oven’s gas â˘typeand â¤confirmâ secure electrical connectors and mounting alignment.The component interfaces with the control board’s ignition sequence and⤠the gas âmanifold pressure, so troubleshooting commonly â˘involves checking ignitor glow time, observing valve actuationand verifying correct orifice selection to restore proper operation.
- Common failure symptoms: long glow time, no ignition, weak or yellow flameor safety valve lockout.
- Compatibility checks: match connector type, mounting orientationand orifice specification for natural vs LP gas.
- Service tests: visual glow, resistance measurementand observing valve response during a controlled ignition cycle.

Diagnostic Indicators⣠and Common Failureâ Symptoms of the Ignitor/Orifice Assembly
The 316536602 Frigidaire âŁOven Ignitor/Orifice Assembly integrates the hot-surface⤠ignitor and the gas orifice into⣠a matched replacement used in Frigidaire gas ranges thatâ employ hot-surface ignition. The ignitor is a resistive heating element that must reach a stable, visible glow to allow the oven’s gas safety valve to open; the orifice meters and shapes the gas flow âso the burner produces a consistent flame. â˘Technically, correct behavior means a clean, steady glow shortly after the control calls for heat, followed by immediate valve actuation and a uniform âflame pattern at the burner port-deviations in glow intensity, timingor flame form indicate either an electrical or flow restriction issue and can point to incompatibility,â wiring âfaultsor a degraded element rather âthan a⣠control-board fault.
- No glow or open circuit: complete âignitor failure or broken filament leads to no ignition.
- Dim or slow-to-glow element: reduced emission current causing long preheat timesâ or failed valve opening.
- Intermittent glow or cycling: poor electrical connection, wiring⢠harness damageor partial elementâ failure.
- Weak, sootyor uneven flame: orifice blockage, incorrect orifice sizingor misalignment of the assembly.
- Gas odor without ignition: delayed âignition causedâ by a weak ignitor permittingâ gas to flow before stable combustion (treat as a⣠safety condition).
| Item | Description |
|---|---|
| Primary function | Provide thermal emission to actuate the gas valve and meter gas âflow for proper flame. |
| Quick diagnostic checks | Visual glow⤠test, continuity check withâ meter, inspect orifice for⤠debris and correct seating. |
| Common fault indicators | Long⢠preheat, no ignition,â dim â˘glow, uneven flame or gas odor before ignition. |
For practical troubleshooting, start withâ a visual and electricalâ check: confirm the element glows within a few⤠seconds of a bake or broil call and verify continuity and connector integrity with a multimeter; a measurable but reduced emission current typically indicates a marginal ignitor that will fail under load. Inspect the orifice and burner ports forâ carbon, spider webbingor cooking debris that can restrict flow and produce weak or sooty flames; replacing the assembly with the correct 316536602 unit resolves many cases where both ignition strengthâ and metering geometry must be restored to factory specification. When symptoms âpersist after replacing the assembly, verify wiring, control outputsandâ that the replacement orificeâ matches the oven’s specification to âŁavoid repeated failures.
Compatibility, Replacement Considerationsand⢠Step-by-Step Installation Procedures
The 316536602 âFrigidaire Oven Ignitor/Orifice Assembly pairs a hot-surface⤠ignitor with the matched gas orifice toâ provide reliable ignition⢠and consistent burner flow. The ignitor is aâ high-resistance â¤silicon carbide/tungsten element that must reach a âspecified glow temperature to allow the safety valve to open and the orifice⣠to meter gas correctly; mismatching the orifice diameter or mounting position changes flame size and â˘cook performance. Compatibility is governed by mounting geometry, electrical connector type and voltageand theâ orifice drill size appropriate for the appliance’s âfuel âtype (natural gas vs. liquid propane). Technicians should verify the OEM part number against the appliance model and confirm that the orifice marking⤠and connector align with the original assembly before replacement to avoid flame instability⢠or⢠safety interlocks failing to operate as intended.
- Check physical mounting and bracket alignment to ensure the ignitor tip is positioned⤠for proper âflame âŁstabilization.
- Confirm electrical connector style and voltageâ rating match the appliance harness â˘to prevent improper current draw.
- Verify orifice size and fuel type;⤠LP conversions require different orifices and pressure regulation.
- observe symptoms: slow ignition, weak flame, oven not reaching setpointor safety valve not opening indicate ignitorâ or orifice issues.
Replacement and installation are âŁstraightforward but require safety⤠and diagnostic steps: shut off electrical power and gas supply, remove access panels to â¤reach the burner box, disconnect the ignitor harnessand⤠unfasten the â¤mounting screws or âretaining clip. Replace the assembly with âthe 316536602 unit ensuring the ignitor element sits in the same orientation andâ the orifice threads seat fully; reconnect the harness and gas line components per torque specifications. After reassembly, restore gas and electrical supply, perform a leak check at fittings âwith âŁa soap solutionand observe several ignition cycles to confirm stable flame characteristics and normal current draw. If âignition timing or flame size remains abnormal, re-check orifice markings, manifold pressureand electrical resistance of the ignitor against the service manual values before declaring the repair complete.

Q&A
What is the 316536602 Frigidaire Oven Ignitor/Orifice Assembly and what does it do?
The 316536602 is an OEM replacement assembly used on certain Frigidaire⣠gas ovens/ranges that combines the hot-surface ignitor⤠(or spark/igniter arrangement depending on model) with the gas orifice (the jet that meters gas).â The ignitor heats and/or provides a spark to ignite gas released through the orifice; the orifice controls the gas flow and size of⣠the flame. Together they allow⢠the oven burner to light reliably and safely.
What are common symptoms that this ignitor/orifice assembly is failing?
Typical signs include: the oven burners fail to light or take a long time to light,⤠the ignitor glows weakly or⣠not at all, intermittent ignitionâ or repeated clicking, the oven won’t reach set temperatureor an⢠orange/yellow rather of a steady blue flame.A strong⤠smell of gas without ignition is also a symptom – shut the appliance off and ventilate promptly if you smell gas.
Can I test the ignitor with a multimeter? What should Iâ look for?
You can do a basic continuity/resistance check with the power off: disconnect the⢠ignitor connector and measure across the ignitor terminals. A very high or⤠openâ reading indicates a failed element. Tho, continuity alone doesn’t prove the ignitor is strong enough to open the gas valve; many failing ignitors still show⣠continuity. For a conclusive test professionals measure current draw (amperage) while the ignitor is powered or compare the âŁignitor’s warm-up behavior to the⤠manufacturer’s specification. If you’re unsure, have a technician perform the live current test.
Is the 316536602⤠compatible with âmy Frigidaire model? How do I confirm⢠fitment?
Compatibility depends on your exact appliance model and productionâ date. Locate your range/oven model number (usually⢠on a tag inside the oven door frame, behind a draweror on the rear panel) and âŁcrossâreference it againstâ Frigidaire parts â¤lists or âthe partâ seller’s compatibility chart. Do not assume visual similarity equals fit – always confirm by model number or OEM crossâreference.
Can Iâ replace the assembly myself? â˘What safety steps should⤠Iâ take?
Homeowners with mechanical experience canâ replace the assembly, but you must follow strict safety steps: turn off and disconnect electrical power to the appliance, shut off the gas supply, ventilate the areaand follow âthe âmanufacturer’s disassembly instructions. After installation check all gas connections âfor leaks using a soapyâwater solution (do not use an open flame). If you’re â˘not comfortable working with live gas or wiring, hire a qualified appliance technician.
Do I have to replace both the ignitor and the orifice togetheror can⤠I replace only one part?
It depends on the failure and âwhat parts are available. The⣠orifice (jet) rarely fails, whereas the ignitor wears out more â¤commonly. Some OEM assemblies are âŁsold as a âŁcombined unit (ignitor plus orifice) and some components may be âavailable separately. âIf converting between âŁnatural âgas and LP, you must use â˘the correct orifice size for the â¤fuel type. Always use partsâ specified for your model and fuel type.
How do âI handle LP (propane) versus natural gasâ when replacingâ this assembly?
Orifice size determines fuel flow and is specific to the fuel type. If your appliance is set up for natural gas⤠and you convert it to âŁLP (or vice â˘versa), you must install the correct orifice and adjust the âregulator/settings as instructed âby Frigidaire. Many manufacturers provide conversion kitsâ and official instructions. Do not attempt fuel âconversions without the correct parts and procedures – contact a qualified technician if needed.
How long does this part typically last and âwhat will âit cost to replace?
Service life âvaries with usage âand conditions,but oven ignitors commonly last several⣠years (often 5-10 years) before weakening. Moisture, soot/carbon buildupand repeated thermal cycling reduce life. Retail prices⢠vary by seller and whether you buy only the âignitor orâ the combined assembly; expect a wide range depending on source âŁand model – check current listings or a Frigidaire parts dealer for exact pricing.Labor costs will add to a professional replacement ifâ you hire âa technician.
Final Thoughts
The 316536602 Frigidaire Oven Ignitor/Orifice Assembly â˘plays a central role in safe and effective oven operation by initiating and âŁregulating the combustion sequence that produces heat. Proper function of the ignitor âand orifice contributes directly to consistent temperature control,⤠reliableâ bake and broilâ performance, âand âefficient fuel use; conversely, wear or failure in this assembly can âcause delayed ignition,⤠uneven⢠cooking, longer preheat cyclesor unsafe gas conditions.
