316536610 Frigidaire Ignitor/Orifice Assembly is a combined ignition and gas metering service â¤part used in⣠Frigidaire gas cooking appliances. The assembly typically âintegrates an ignitor âŁelement (either a hot-surface ignitor or spark electrode) with a dedicated orifice nozzle that meters â¤the flow of fuel to a⣠specific⢠burner or⢠ovenâ port.As â¤a field-replaceable component, it is â˘designed⤠to âinterface mechanically and electrically with⤠the appliance’s burner head and mounting bracketand to âbe compatible with the âappliance’sâ specified gas â¤type and pressure requirements.
Inside theâ appliance, âthe ignitor provides theâ energy⣠required to⣠initiate combustion while the orifice sets the downstream gas flow rate and flame geometry. âThe part therefore directly âinteracts with the gas supply⢠line, the main gas valve or solenoid, the control module â˘or⣠thermostat that calls for â˘heatand any flame-sensing orâ safety interlock âcircuits. Correct function of both elements⤠is vital for reliable â˘ignition timing, â˘stable combustion, âproper âtemperature control,â and prevention of unburned fuel accumulation that coudl pose a âsafety risk.
This âarticle will explain⣠the functional principles â˘of the 316536610 assembly,indicate typical appliance models and gas-type compatibility considerations,and describe common failure symptoms such âas delayed ignition,weak or uneven⢠flame,repeated valve⤠cycling,or an unlit⢠burner with gas⢠odor. It will outline practicalâ troubleshooting âsteps-visual inspection,⣠continuity and⣠resistance checks on the ignitor, voltage âverification atâ the harness,â inspection â¤and cleaning⣠of the orificeand basic gas-pressure/orifice checks-and discuss replacement considerations including correct â˘part matching for NG versus LP service, proper mounting and sealing, post-installation leak testingand when to engage⣠qualified service personnel.

Functional Role and performance Requirements of the Ignitor/Orifice Assembly in â¤frigidaire Gas Burners
The â316536610 Frigidaire Ignitor/Orifice⢠Assembly integrates the ignition element âandâ gas metering nozzle into a single serviceable unit, providing⤠both â¤the energy source to initiate combustion âand the⢠preciselyâ sized orifice that determines gas flow⣠to the burner. âŁIn typical Frigidaire gas⣠burners this assembly âpositions the⢠ignitorâ electrode or â¤hot-surface element⤠immediately adjacent to âthe gas âjet soâ that theâ discharge or â¤heated surface reliably lightsâ the fuel/air âmixture; the âspatial alignment, electrode gapâ and nozzle⢠orientation are critical to repeatable ignition. Compatibility depends on â¤matchingâ the orifice drill size and ignitor style to the appliance’s gas â¤type (natural vs.LP), manifold pressure and â¤mounting interface – substituting an orifice with the wrong diameter â¤or an ignitor with diffrent â˘geometryâ will change flame shape,â combustion efficiency â˘and âcan produce soot or yellow-tipped flames.
Performance requirements for the assembly include consistentâ ignition across âŁthe valve’s modulation range, stable flame âcharacteristicsâ at the design âBTU outputand resistance to foulingâ under typical kitchen conditions.Technicians evaluate the component â˘by observing flame color and inner cone stability, checking electrode gap⢠andâ insulation â˘for âcracksand verifying that orifice⤠flow matches specification; continuity or resistance checks âŁmay diagnose a failed hot-surface ignitor while âvisual and pressure checks identify orifice-related problems. Practicalâ service actions include replacing with the correct OEMâ or matched-specâ part, cleaning carbon âdepositsâ from the⣠nozzle and â¤electrodeand confirming manifoldâ pressure or gas⤠conversion âsettings⢠after orifice⤠changes to restore intended burner performance.
- Inspection checklist: electrode âgap and insulation, âorifice cleanliness and drill size, mount alignment, flame color and stability.
- Common⤠symptoms⢠of mismatch/failure: no ignition, delayed⣠ignition, âweak or yellow â¤flame, sootâ accumulationor inconsistent burn across burners.

How the 316536610 Frigidaire Ignitor/Orifice⢠Assemblyâ Works Inside the Appliance
The 316536610 Frigidaire Ignitor/Orifice assembly combines a hot-surface ignitor with a matched⤠gas orifice to provide controlled ignition and metering for⢠a gas âburner â¤in compatible Frigidaire⤠ovens andâ ranges. The ignitor â˘element heats to a visible glow âto⢠initiateâ combustion; once⢠the element reaches its âŁoperating âŁtemperature and electrical⤠characteristics, the gas valveâ is allowed to flow gas throughâ the orifice. The orifice determines the gas jet âŁsize and primary air/fuel ratio for theâ burner, so correct âorifice sizing andâ orientation are required for safe, efficient flame shape âŁand heat output. Installers should â¤confirm model compatibility âand weather the appliance⢠uses natural â¤gas â¤or LP, as orifice size and conversion requirements differ between fuel âtypes.
Behaviorally, â˘the assembly is aâ timing and flow control subassembly: the ignitor’s warm-up time â¤and current draw⣠control the sequence of â¤gas â˘admission, while âtheâ orifice⤠sets the steady-state flame âŁcharacteristics. Common practical symptoms of a failing assembly include slow or no ignition,a weak or yellow (sooty) â¤flame,longer heat-up âtimes,or ovensâ thatâ cycle abnormally; these indicate either insufficient ignitor âŁoutput or incorrectâ gas metering. Technicians typically inspect the ignitor forâ proper âglow,â verify secure electrical and gas â¤connections,â and confirm correct orifice type for the fuel;⢠replacement corrects mismatches between required and actual gas flow or restores the reliable thermal behavior needed to operate the valve and burner⤠reliably.
- Function: hot-surface ignition combined with⢠fixed gas metering via⤠the âŁorifice.
- Behavioral signs: delayed ignition, weak flame,â incomplete combustionor longer recovery times.
- Compatibility: matched toâ specific Frigidaire models and fuel type (natural vs LP); verify part fit and orificeâ sizeâ before installation.
| Item | Description |
|---|---|
| Primary â¤role | Provide the âŁthermal stimulus for valve operation and aâ fixed gas jetâ for correct burnerâ performance |
| Fuel considerations | Orifice size âdiffers for natural gas⤠vs âLP; â¤conversion requires the correct orifice and perhapsâ regulator adjustment |
| Electrical â¤interface | Low-voltage ignitor connection to⣠the oven âcontrol/ignition circuit; ignitor must reach operating temperature/current before⢠gas admission |
| Diagnostic checks | Visual glow inspection,flame â˘shape assessment,and verification of⤠secure mounting⢠and gas line fittings |
Common Failure Symptoms and diagnostic Measurements â˘for Ignitor/Orificeâ Malfunction
The 316536610 Frigidaire Ignitor/Orifice âŁAssembly combines the ignition element and⣠the⤠gasâ metering orifice into⢠a single â¤serviceable unit that controls â¤both the âŁelectrical initiation â˘of â¤combustionâ and the fixed fuel flow to⢠the burner. Functionally, the âignitor must reach its design temperature or receive the⢠correct electrical energy to allow theâ valve to open and âestablishâ a stable âŁflame; the orifice must deliver the intended flow rate for that specific Frigidaire model. Compatibility matters:⤠installing an orifice with â¤the wrong diameter or an ignitor that draws a⢠differentâ current can produce slow ignition, hunting or lifting flames, reduced heat output, âor repeated shutoff. For practical troubleshooting, observe behavior⤠under a⣠controlled test-if the burner takes several seconds to â˘light while the ignitor is visibly dim âor âŁreads open⣠on⣠a continuity âcheck,â the ignitor isâ likely failed; if the ignitor glows normally but the flame is weak or âyellow,⣠inspect the orifice and⢠manifold pressure for ârestriction or incorrect sizing.
- delayed ignition or long glow time – measure⢠ignitor voltage during aâ call for heat and check elementâ continuity.
- Weak,⢠smallor yellow/sooty flame – inspect â¤orifice for âblockage and verify manifold/static pressure against⢠OEM spec.
- Intermittent flameâ or burnerâ that won’t stay lit â-â compareâ flame pattern to a known-good âburner âand check for⤠loose wiring or valve response.
- Ignitor⤠glows but no⢠gasâ flow – indicates possible valve/control issue or⤠orifice blockage despite correct electrical â˘behavior.
Diagnostic measurements that provide definitive âdirection âinclude a cold-resistanceâ check of the⤠ignitor with a multimeter â˘(many hot-surfaceâ elements measure in the tens of ohms), verification that line voltage (approximatelyâ 110-120 VACâ on affected ranges) âis present at the⢠ignitor terminals during a â˘call for âheatand aâ visual âand âdimensional inspection of âŁthe orifice. For gas flow verification⤠use a manometerâ to confirm manifold pressure and compare flame âlift, sizeand color to manufacturer âŁreferences; a restricted orifice âŁtypically produces a small, â¤sooty flame, whereas⢠excessive âflow or âwrong orifice⢠sizing can produce a lifting or noisy blue flame. Replaceâ the 316536610 â¤assembly⢠or its individual subcomponents only after confirming which measurement â˘fails to⢠meet theâ model-specific specifications.
| Item | Description |
|---|---|
| Ignitor âresistance | Cold resistance typically in theâ tens of âohmsâ for many â¤designs; open circuit â¤indicates failure. |
| Supplyâ voltage | Confirm ~110-120 VAC (model-dependent) atâ ignitorâ when⢠control âŁcalls for heat. |
| Flame characteristics | Blue, stable flame indicates proper flow; yellow,â lifting,⤠orâ sooty flame suggests restriction or wrong orifice. |
Compatibility, Replacement Considerations, Installation Procedures and Troubleshooting Workflow
The⤠316536610 Frigidaireâ Ignitor/Orifice Assembly integrates⢠theâ ignition electrode and a calibrated gas orifice to both initiate combustion and metre fuel to a âspecific burner. âThe electrode generates a spark at the âŁprecise ignition point while the orifice restricts and shapes gas flow to produce theâ designed flame⢠characteristicsâ for⢠the appliance model and⤠gas⣠type (natural or⤠LP). âCompatibility is resolute by âŁphysical fit, mounting flange orientation, gas port sizeand the connector/wiring interface;â replacing the assembly requires verifying those parameters against the âappliance model number⢠and service parts⢠list. Such as, installing an âassembly with an âLP orifice into a natural-gas-configured manifoldâ will produce unstable, sootyâ flames and delayed ignition because the orifice⢠flow and manifold⣠pressure no longer match the burner design.
Shut âŁoff gasâ and electrical power before â¤any service. A âpractical replacement and âtroubleshootingâ workflow starts with documenting the original assembly⤠orientation andâ electrode gap, isolating utilities, âand visually inspectingâ for clogged orifices â¤or damaged electrodes.⤠Use the following checklist â¤for aâ focused diagnostic sequence:⢠confirm visible spark generation,listen for proper gas flow during valve actuation,inspect the orifice âfor â˘obstruction or incorrect size,and verify secure electrical and ground connections. Symptoms such as continuous clicking with no âflame,â a hissing sound without ignition, âŁor a âpersistent yellow/sooty âflame point toward orifice mismatch, âblockageor an ignition electrode fault; after â˘replacement perform a leak âtest, then observe flame stability⤠and⣠ignition timing⢠underâ normal â¤operating âŁconditions. If problems persist, proceed to verify âŁmanifold âvalve operation and âŁcontrol-module â¤outputs before âŁassuming â¤a new assembly is defective.
- Verify model fit, gas type (Natural vs. LP)and mounting alignment before replacement.
- Document electrode âposition and wiring before removal⣠to ensure correct reassembly.
- Check â˘for debris âin â¤the orifice and for secure gas âfittings to avoid leaks.
- Test ignition visually and confirm flame quality andâ timing after reinstallation.

Q&A
What is the 316536610 Frigidaire ignitor/orificeâ assembly â¤and what does it do?
The 316536610 is a⣠combined hot surface ignitor and orifice assembly used⣠on â˘many Frigidaire gasâ ovens/ranges. The ignitor heats until it glows, which allows the gas valve to⤠open and the oven burner to light; the orifice is⤠the small nozzle that meters âthe gas flow to the burner. Together they control ignition and â¤the âcorrect gas deliveryâ for the bake/broil burner.
How⣠doâ I know if â˘the⢠ignitor/orifice assembly is bad?
Common⢠symptoms are: â¤oven doesâ notâ light or takes a long time⤠to light, ignition clicking or no glow from the ignitoror⢠the âignitor glows but the burnerâ never lights. Physical signs â˘include â¤a cracked or⤠crumbly ceramic â˘ignitor or a visibly clogged orifice. Always checkâ for continuity with a multimeter and inspect the ignitor⣠for visible⤠damage before replacing.
How can âI test the ignitor with a multimeter or âammeter?
With power disconnected, test⢠the⢠ignitor for continuity⢠using an ohm âŁmeter – âa good hot surface ignitor âtypically shows a low resistance⣠(commonly in â¤the tens to low hundreds of ohms; many âare roughly 40-120 Ί,â depending on type). Ifâ it⤠reads open/infinite, âit’s failed. To âconfirm operation under load,⤠a â˘clamp⢠ammeter âon the live leadâ while the oven attempts to ignite will showâ current draw; âŁmany working oven ignitors draw roughly 2-3.5⣠A when heating. If the ignitor’s current is considerably lower than âexpected itâ may glow but not⣠get hot enoughâ to open the gas valve.
Can I⣠replace the 316536610 myself? What are the basic steps and safety precautions?
Yes, aâ competent⣠DIYer can⤠replace it,â but âobserve strict safety steps: turn off electrical â˘power and shut off the gas⤠supply before starting.â Typicalâ steps: remove âŁthe oven â¤access panel,⤠locate and⣠unplug theâ ignitorâ wires, remove mounting⤠screws and the orifice â˘if required,⢠swap assemblies, reconnect⤠wiring, restore gas and powerand⢠test for correct â¤operation and leaks.â Use proper tools⢠(screwdrivers, nut drivers, multimeter) and test for gas leaks with âa⤠soapyâ solution.If you are not pleasant working âwith gas or live wiring, hire a qualified technician.
Will this âpart fit⢠my Frigidaire model?
Compatibility dependsâ on the exact model and âŁproduction date of âyour appliance. The 316536610 fits a range of Frigidaire gas ovens and someâ related â˘brands, but you must verify â˘fit by âŁchecking your oven’s model ânumber against⤠the partâ number in â˘the manufacturer’s parts listâ or a reputable parts supplier. Do not â¤assume fit by appearance alone-connector type,⢠mounting holes, âorificeâ sizeand wire lead length must match âyour oven.
does the assembly come set up âfor natural gas or propane â¤(LP)?
many assemblies are supplied⣠for natural gas. Propane (LP) â˘requires a âsmaller â¤orifice and often different pressure/regulation settings; some kits are LP-convertibleâ or sold with LP orifices. Beforeâ converting, confirmâ whether the part you buy includes the correct orifice for LP or obtain a âŁcertified conversion kit âand have â¤conversion⢠performed by a qualified âtechnicianâ to maintain safe operation and compliance with localâ codes.
What⤠tools and parts should I have⤠on hand âand does the assembly include mounting hardware?
Common tools: screwdrivers or nut⣠drivers â(oftenâ 1/4″ orâ 5/16″),pliers,multimeter,and optionally a clamp ammeter âand leak-detection solution. Some âŁaftermarket or OEM assembliesâ include the ignitor and orifice but may not include all mounting screws or gaskets; check the product description. If âhardware or gaskets aren’tâ included, reuse the original pieces⤠if in good âcondition or source replacements before âstarting.
How long do ignitor/orifice assemblies last âand what causes premature⢠failure?
Typical life â¤is several⤠years (frequently enoughâ 5-10+ years)â but âvaries with usage, cycling frequencyand surroundings. Common failureâ causes⤠are thermalâ cycling⤠(repeatedâ heating/cooling), mechanical damage,â electrical⤠surges, contamination or soot buildup on the ignitorand clogged orificesâ from⢠debris or corrosion. Regular cleaning âand â¤ensuring correct⢠electrical supply can extend life. If â˘you see reduced glow,longer ignition times,or visible damage,replacement is âappropriate.
