316536610 âFrigidaire⣠Ignitor/Orificeâ Assembly⢠is a combined ignitor âandâ gas⤠orificeâ module used in Frigidaire gas cooking appliances; it is a service-replaceable component âthat⤠provides the initiating heat âŁor spark for â¤burner combustion â˘while also restricting⢠and directing⣠gas flow through a precisely sized orifice.As a functional subassembly, it integrates the ignition âŁelement â¤(typically a hot surfaceâ ignitor or spark electrode, âdepending on the⢠model) with the orifice fitting that âmeters gasâ from â¤the appliance manifold⢠to â¤the burner head.
Inside the appliance, theâ ignitor/orifice assembly interfacesâ directly âwith the gasâ supply, the burner head, the â¤safetyâ gas â˘valve, â˘and the control electronics or thermostat.Onâ ignition command, the â˘ignitor generates the energy required to light the âgas delivered through the orifice; the⤠orifice sizeâ determines⤠local gas flow rate and contributes âto flame geometry and heat output. The assembly âthus participates in ignition sequencing,⢠flameâ stabilityand temperature control, âŁand it must operate⤠correctly in concertâ with âsafety interlocks âŁ(flame âsensors, thermal cutouts) and the appliance’s control board to prevent misfires orâ unsafe âgas flow.
This article willâ describe the â¤assembly’s functional design and typical installation locations, identifyâ common failure symptoms and diagnostic steps â¤a technician or informed owner can use (electrical checks, current draw⤠for hotâ surface ignitors, visual inspection forâ orifice obstruction,⢠and verification of gas flow),⣠and outlineâ compatibility and replacement considerationsâ such âas part verification, sealing and torque practices, leak testingand post-replacement functional âchecks. Emphasis willâ be on providing practical⣠technical guidance⢠for troubleshooting,⢠safe⣠replacementandâ ensuring correct combustion performance rather than product promotion.

Function âand Role of the Ignitor/Orifice Assembly in Frigidaire Gas Appliances
The ⢠316536610⣠Frigidaire⤠Ignitor/Orifice Assembly integrates âan electrical ignitor âwith a precision gas orificeâ to initiate and metre combustion at a â¤single burner in compatible Frigidaireâ gas⤠appliances. The ignitor provides the âenergy (spark or âhot-surface âŁheat) necessary âto ignite theâ gas, while⢠the orifice âdetermines theâ volumetric flow forâ the burner’s ârated BTU output; âtogether they establish correctâ flame geometry and âŁstable ignition â˘timing âunder âthe appliance’s âŁdesigned âmanifold pressure. Because the orifice âdiameter and⤠ignitor type âmust âmatch theâ appliance’s valve characteristics and flame-sensing system, replacement âparts should be cross-referenced to â˘model specifications rather thanâ substituted by appearance alone to avoid⤠weak flames or failures of safety⢠interlocks.
Operational behavior⤠and failure modesâ are straightforward: when a â¤control requests heat the ignitorâ energizes and theâ gas valve â¤opens,â gas⢠passes through the orifice andâ the ignitor initiates combustion; flame âŁpresence â˘is then confirmed⤠by âflame sensingâ circuitry which permits continuous gas flow.â Common issues include clogged orifice⢠passages,cracked⣠or â¤glazed ignitor elements,electrode âmisalignment,corroded connections,and incorrect orifice â¤sizing after service.â Technicians verify serviceability âby inspecting for â˘deposits, âŁmeasuringâ ignitor resistance âand operating âvoltageand confirming âŁorifice⣠size andâ manifold pressure against the service manual. Typical symptoms and â˘quick diagnostic checks⤠include:
- Persistent clicking withâ no ignition -⤠check ignitor âŁvoltage⣠and electrode gap, confirm gas valve operation.
- Weak⣠or yellow flame – inspect orifice for partial blockage âŁand verify proper pressure/regulator setting.
- Delayed ignition orâ soot buildup⤠– examine ignitor surface condition â¤and replace if glazed or cracked.
- Intermittent shutoffâ – test flame-sensing circuit continuity and secureâ wiring to the assembly.

How the 316536610 Frigidaire Ignitor/Orifice⤠assembly Works Inside the Appliance
The 316536610 Frigidaire Ignitor/Orifice Assembly integratesâ aâ gasâmetering⢠orifice âand an⤠ignition electrode into a single serviceable unit thatâ controls where and how the â¤burner âignites.â In normal operation the cooktop or oven â¤control opens the gas valve and the orifice meters the flow to the burner; the ignitor âprovides the ignition energyâ (spark or hot surface,depending âon the appliance⢠design) located at a fixed distance from â¤the orifice outlet to ensure reliable â¤flame⤠establishment. Because flame shape and stability âdepend on orificeâ diameter, electrode positionand â¤manifold pressure, replacements âmust match OEM specifications and be verified â¤against the applianceâ model and service documentation⣠to maintain correct combustion performance and safety margins.
Functionally, failures show predictable electricalâ and â˘combustion symptomsâ that guide diagnostics: the ignitor can be checked for continuity and correct resistance, the orifice inspected for clogging or erosionand the assembly’s mounting⣠andâ sealing â˘verified to âprevent leaks. Practical â¤service steps âinclude cleaning carbonâ deposits âŁfrom the⤠electrode area, clearingâ orifice portsâ with lowâpressure â¤air, measuring manifold⤠pressure with a manometer if flameâ qualityâ is⤠poor,â and replacing the â¤assembly if theâ ceramic, electrode, âor orifice is corroded or damaged. â¤Proper reinstallation ârequires correct orientation,⢠torque on the gas âfitting, âand a leak test; incorrect fit âŁor an incorrect orifice size will⢠produce weak, yellowor lifting flames and⣠can cause repeated âŁignition attempts.
- Primary âfunctions: gas metering and ignition positioning for consistent flame.
- Common failure signs:⤠delayed ignition, continuousâ clicking, weak/yellow flameor no ignition.
- Typical service actions:⤠visual inspection, continuity checkorifice âclearing, replacement and leak test.

Common Failure Symptomsâ and âŁMeasurableâ Diagnostic Indicators for the Ignitor/Orifice Assembly
The 316536610â Frigidaire ignitor/Orifice âAssembly functions as the combined ignition element and fixed gas aperture for compatible Frigidaire gas â¤ranges and ovens,â producing the âthermal energy â˘to ignite gas released through⤠theâ orifice.â Mechanically âthe âignitor is a resistive heating element â˘that must reachâ a âspecific temperature to â¤trigger the⤠gas valve; the orifice meters⢠flowâ and â˘affects flame âshape and burn rate. When replacing or diagnosing â˘this assembly, verify physical compatibility â(mounting, â˘electrical connectorand orifice size) with the appliance model âand confirm that the â˘ignitor âandâ orifice âŁare installed âto the correct alignmentâ soâ the glowing element is directly â¤adjacent to the gas stream for⤠reliable ignition.
- Weak or no⤠visible glow but repeated retriesâ toâ light: ignitor has elevated resistanceâ or is partially failed; measure with an ohmmeter and inspect for cracks.
- Oven or burner takes much longer to⤠light or fails to âŁsustain flame: partial âorifice blockage or reduced gas pressure; â˘check âflow â˘path and gas supply pressure.
- Ignitor âtests âopen (infinite resistance) âor shows veryâ high resistance: replace the ignitor â˘portion of the assembly.
- Noâ voltageâ present⢠at the connector âduring a âcall for heat: control board, wiringor safety interlock is⤠highly likely â˘the⢠fault ârather than the âignitor.
- Intermittent glow or visible physical damage: â˘replace the assembly âŁand re-test âto ensure stable⢠current draw and proper âignition⣠timing.
| item | Description |
|---|---|
| Cold resistance | Typically a low value in the⤠tens⢠of ohms; a very âhigh â¤or openâ reading indicates aâ failed ignitor element. |
| Supply â¤voltage during call | Control should supplyâ line voltage (commonly nearâ 120 VAC inâ North Americanâ appliances) âto the ignitor; absence â˘points toâ control/wiring faults. |
Use the listed symptoms and⤠measurementsâ together to âisolate whether theâ problem is the âignitor, the⤠orifice, the gas supplyor the control system: for example, a⣠glowing ignitor with no gas flow⤠suggests an âorifice obstruction or valve issue,â while a â¤non-glowing⤠ignitor with proper âŁsupply voltage âand wiring âusually means the element â˘is open or degraded.For safe and âreliable testing, â disconnect electrical⣠power and âclose the gas âsupply before removing the⤠assembly or making âresistance checksand confirm finalâ operation with the â¤oven at â¤normal operating conditions; if measurements⤠are ambiguous, verify wiring continuity, connector integrity, â˘and â¤gas pressure⢠withâ appropriate meters before replacing the assembly.
Replacement Considerations andâ StepâbyâStep Installation Procedures forâ Ignitor/Orifice Assemblies
The 316536610 Frigidaire Ignitor/Orifice Assembly combines aâ gasâmetering orifice with an ignition â˘element to create a â˘controlled and repeatable ignition event â¤atâ the âburner. The orifice determines the volumetric gas flow for a given â¤manifold pressure,â while the ignitor (spark electrode â˘or hot surface depending on⢠model) âinitiates combustion;â mismatches between orifice sizeâ and theâ appliance’s âgas type (natural vs. LP) or manifold pressure will change flame shapeâ and heat output and can produce delayed ignition, noisyâ flamesor a persistent yellow tip.Verify compatibility byâ checking the range/oven model plate and theâ gas typeâ before replacement, âand document the orientation âand wiring of the existing âŁassembly to â˘preserve original burner geometry and electrode positioning during installation.
Follow methodicalâ safety and diagnostic steps⢠when replacing theâ assembly:â shut offâ gas and power, relieve any residual âgas⢠pressureandâ work âwith âthe appliance cold. After âremoval, install the replacement assembly âŁwith âthe same â¤orientation⤠and sealing practice âas the original, tighten fasteners to the manufacturer’s guidance without overâtorquingand⢠reconnect electrical leads using the original connectors or properly crimped âterminals. After reassembly âperform a leak test at the orifice/manifold connection, then energize⣠the ignition system and observe âthe â˘ignition timing⣠and⢠flame characteristics; if ignition delay,â intermittent sparksorâ an unstable flame âpersist, verify manifold âŁpressure â˘with âa manometerâ and â˘confirm the â˘orifice size matches the appliance â¤gasâ specification.
- Step 1: shutâ off gas and electrical supply and ventilate â¤the workâ area.
- step â2: Remove grates/burner caps and âaccess panels; photograph original assembly⢠for reference.
- Step â¤3: Disconnect ignitor wiring, remove mounting âfastenersand extract the assembly taking⢠careâ not to⢠bend the â¤electrode.
- Step 4: install replacement⣠316536610â Frigidaire âIgnitor/Orifice Assembly in the⢠same â¤orientation, secure fasteners per⤠service guidance, âand reconnect wiring.
- Step âŁ5: â¤perform a⣠soapâbubble leak check, restore gas and âpower,â observe ignition sequence⤠and flame colorand verify âstable combustionâ under normal operating conditions.
| Item | Description |
|---|---|
| Compatibility check | Confirm appliance model and gas âtype (Natural vs LP) to âŁselect correct orifice⤠size âand ignitor variant. |
| Leak test | Applyâ soapy solution at connections; no bubbles at operating pressure âindicatesâ an acceptable seal. |

Q&A
Whatâ is⤠the 316536610 Frigidaire Ignitor/Orifice Assembly⤠and what âdoes it do?
The 316536610 is an ignitor/orifice assembly used onâ certain Frigidaire gas ovens/ranges. The ignitor is a hotâsurface or spark device that initiates combustion; the orifice (jet) meters the amount⢠of â¤gasâ delivered⣠to the burner.Together⤠they light the⤠burner and control flame size so the ovenâ or cooktop â˘reaches and âmaintains the correct temperature.
howâ do âI know ifâ the⢠316536610 is compatible with my Frigidaireâ appliance?
Check your appliance model number (usually âon a tag âbehindâ the âŁdrawer, â˘on the oven frameor â¤inside the door frame) and crossâreference it with âŁthe part ânumber⣠using Frigidaire’s parts â¤lookup or⤠a trusted parts âdistributor.Do not rely only on physical appearance – some â˘assemblies lookâ similar butâ have different orificeâ sizes or mounting configurations. If in doubt, provide your âmodel number to the parts âsupplier or Frigidaire for confirmation.
What symptoms indicate the ignitor/orifice assembly is failing?
Common signs include: theâ burner won’t light âorâ takes a long time to light, aâ weak or yellow/sooty âŁflame, the oven not reaching set temperature, repeated⤠ignition⤠attemptsor the oven locking out. Ifâ the ignitor no longer âglows reliably (for hotâsurface types) or if gas is not flowingâ correctly, theâ assembly should be inspected.
How can I testâ the ignitor and orifice â˘to determine if they are defective?
Visual âand electrical checks are typical: visually inspect forâ cracks, âŁbreaksor heavy sooting; âŁobserve whether the ignitorâ glows strongly âwhen the burner is called for (hotâsurface⤠type)⢠or whether â¤the spark occurs (spark systems). Use aâ multimeter to check for continuityâ on the ignitor (no reading may indicate an open âelement),and measure âcurrent/voltage under call for heat if you can safely â¤do so â- a weak⢠current draw can indicate the ignitor is ânot drawing enough â¤to open the gasâ valve.For the orifice, inspect for blockages âor debris; a â¤clogged orifice will reduce or distort âthe flame.â Ifâ testing requires accessing⣠gas fittings or electrical⤠live circuits,shut offâ power and gasâ first or call a technician.
Can I replace the 316536610 myselfandâ what âŁare the â˘basic â¤installation/safety steps?
Competent DIYers â¤can replace it, but you⤠must follow safetyâ precautions: turn âŁoff electrical power to the applianceâ and shut âoff⢠the âgasâ supply⢠before starting. Remove oven/burner access panels, disconnect the wiring harness to the ignitor, unboltâ the old⢠assemblyand âinstallâ the new âone in the same orientation. Reconnect wiring,â restore gasand check all â˘connections⣠for âŁleaks withâ a soap solution â˘(do âŁnot⣠use⤠open flame). Restoreâ power andâ observe a few ignition cycles. If you are uncomfortable working with gas or mains âelectricity, hire âa qualified applianceâ technician.
Is this â¤part â˘for naturalâ gas only âor can it be used for propane (LP)?
Theâ orifice âsize â¤must match the fuel type.⤠Many OEM assembliesâ are sizedâ for ânatural gas; converting to propane typically requires a smaller orifice (and sometimes âa conversionâ kit) plus adjustment of the regulator/burner settings. Do not runâ propane through a naturalâgas orificeâ without proper conversion – it can create⢠an unsafe⣠flame. âŁVerify the âfuelâ type and, if needed, use the correctâ LP orifice/conversion parts and follow manufacturer conversion instructions.
Does replacing the⢠ignitor/orifice require âany calibration orâ adjustmentâ afterward?
In moast cases no electronic âcalibration⣠is required:â once installed and the appliance⢠is reassembled,the âburner â˘should ignite and the flame â˘size should beâ correct for that orifice. Though, if the âŁflame is too large/small or⣠unstable, the orificeâ size, burner⤠alignmentor air shutter settings⣠may need adjustment. Also, if the⣠appliance has a thermostat or control board that loggedâ faults, those may âneed to âŁbe cleared â˘per the service manual. if uncertain, have a technician verify⤠flame âcharacteristics â˘and âsafety operation afterâ replacement.
What does â¤theâ 316536610⤠kit include and should I buy OEM⢠or aftermarket?
Contents vary by supplier. â¤OEM kits commonly include the ignitorâ element and âŁthe orifice/jet assembly⤠and sometimes basic mounting hardware; some listingsâ mayâ not includeâ screws, gasketsor connectorâ clips. Check the â¤product description⢠before purchase. OEM parts â˘guarantee fitment and original specifications; quality aftermarket parts can be âŁacceptable but verify âorifice sizing and connector compatibility. When in doubt forâ safetyâcritical â¤gasâ components, âchoose⤠anâ OEM⤠or a reputableâ replacement and confirm âŁcompatibility⤠withâ your model.
