316536623â Frigidaire Ignitor/Orifice â˘Assemblyâ is a combined âignition and gas metering subassembly used on Frigidaire gas cooking appliances; it integrates âŁan⣠ignitor âŁdevice with a fixed gas orifice to initiate and regulate burner combustion. As a field-replaceable component, the⣠assembly typically consists of a hot âsurface or glow ignitor or an⤠electrode-style⢠ignitor depending on model series, a precisely sized orifice to set fuel flowand mechanical mounts and âgas fittings that locate it at the burner throat.
Withinâ the âappliance, the ignitor/orifice assembly performs two primary functions: producing the energy required to ignite the gas and providing the âcorrect fuel flow for stable combustion. It interfaces âŁdirectly with the gas âvalve and âŁregulator (toâ receive pressurized fuel), the control board or manual valve⢠(for timing and sequencing⣠of ignition)and flame-sensing or safety devices that confirm prosperous ignition.⤠Proper function âŁaffects burner light-off time,â flame shape and stability, heat output,⢠and safetyâ interlocks; an incorrectly sized or damaged orifice or a âŁfailing ignitor can cause delayed ignition, incomplete combustionor shutdowns initiated by flame sensors or⤠safety controls.
This article⤠will cover the assembly’s âŁintended function, how to verify â˘model compatibility and identify equivalent âpart â˘numbers, common⤠failure⤠symptoms to watch â¤for, practical troubleshooting steps for technicians⣠and âinformed owners (including electrical and âgas-flow âŁchecks)and replacement considerations such as matching⣠orifice sizing, mechanical fitment, sealing and torque requirements, âand âverification â¤testing after installation. The facts is presented to âhelp âdiagnose ignition and combustion issues systematically and to guide decisions⤠aboutâ repair versus component replacement while observing âmanufacturer service⣠instructions and applicable safety⢠practices.

Function and Operational Role ofâ the Ignitor/orifice in Frigidaire Gas Burners
The 316536623â Frigidaire Ignitor/Orifice Assembly integrates the ignition element and the â˘fixed gas metering orifice⣠so âthe burner receives the correct gas flow and aâ reliable ignition âsource.The ignitor provides the energy to⣠ignite the âair/gas âŁmixture (either asâ a⣠hot surface or spark type depending on the appliance), while the orifice restricts âflow to theâ calibrated rate required for that burner port. Proper function depends on correct installation,⢠alignment⢠and sealing: the ignitor must be positioned to deliver energy at the burner ports and the orifice must match the appliance’s design to maintain âŁintended BTU output and stable combustionâ characteristics.
Operational faults typically present as delayedâ ignition,â weak or unstable flame, âcontinuous â˘clicking âŁwith no lightor âyellow sooting instead of a blue flame; these indicate either an electricalâ failure in the ignitor or a restricted/mis-sized⢠orifice. Useful diagnostics include âŁa visual inspection, continuity/resistance check of the ignitorand inspection/cleaning ofâ the orifice inlet; confirm correct⢠part number and mounting â˘orientation before replacement to preserve factory gas flow and safety margins. For example, a slow ignitionâ with⣠a normal clicking cadence often points toâ a degrading ignitor â˘element, whereas a large noisy flame⤠can indicate an orificeâ sized for a âhigher BTU rating or a leak upstream.
- Common symptoms: delayed ignition,weakâ flame,continuous clicking,yellow/sooty flame.
- Basicâ checks: visual damage,ignitor continuity,clear orifice⤠passage,correct part and mounting.
- Service tip: âreplace as an âŁassembly if the⢠ignitorâ or orifice condition is uncertain to restore factory-calibrated performance.

How the 316536623 Frigidaire Ignitor/Orifice assembly Controls âGas Flow⤠and Initiates Ignition
The â¤316536623 Frigidaire Ignitor/Orifice Assembly⣠combines âa precision gas orifice with an ignition element so the burner â¤receives a controlled fuel flow at the moment an ignition â˘source âis present. âWhen the range or âŁoven control opens the gas âŁvalve, gas is forced âŁthrough the orifice, which⢠provides âa calibrated pressureâ drop âand volumetric âŁrestriction to set â¤the correct flowâ rate for that⣠burner. The ignitor, located promptly âadjacent to the burner ports, is energized at the same time as the valve opening; depending on design it either produces a high-voltage spark or glows as a hot-surface element to heat the gas/air mixture to ignition temperature.The âphysical alignment and spacing⢠ofâ the âorifice and ignitor are critical: misalignment changes mixing characteristics and can delay ignition or alter⢠flame shape.
Performance and compatibility are governed by âŁtwo practical âfactors: orifice âdiameter (which determines BTU flow at given manifold pressure) and ignitor output/placement (which determines ignition â¤reliability).â Using the âcorrect OEM assembly maintains correct â¤flame size, colorand ignition timing; substituting an incorrect orifice or âan ignitor with different characteristics can cause âweak or yellow flames, repeated ignition cyclesor safety âlockouts. Technicians typically inspect the assembly forâ cracked ceramic, â¤corrosionor⣠cloggedâ orifices and verify ignitor continuity and proper mounting before replacement. Common observable behaviors and â˘useful reference points are âsummarized below to aid troubleshooting âŁand part selection.
- Matched components: orifice size set âŁfor specific manifold pressure and âburner design; ignitor type matched âto ignition system.
- symptoms of âŁfault: âŁdelayed ignition, weak flame, continuous sparkingor soot/sooty flame.
- Inspection cues: physical âdamage to ceramic, clogged orifice port,⣠loose mountingor visible degradation of ignitor tip.

Common â¤Failure âŁSymptoms and⤠Diagnostic Indicators of ignitor/Orifice⣠Malfunction
The 316536623 Frigidaireâ Ignitor/Orifice Assembly combines a âŁhot-surfaceâ ignitor element with âthe â˘matched gas orifice to provide ignition âŁenergy and controlled fuel⤠metering for âthe burner. The ignitor âmust reach a prescribed glow intensity and sustain enough current to actuate⢠the gas valve â¤timing, while the orifice provides the designed flow rateâ and⣠flame geometry âfor correct combustion. âAs the â˘two functions â¤are integrated, electrical degradation of⢠the ignitor or partial obstruction/mismatch of⢠the orifice can âŁproduce overlapping âsymptoms – delayed ignition, repeated valve cycling, âpoor temperature recoveryor abnormal flame âcharacteristics – so technicians should verify mechanicalâ fit, connector âtypeand electrode alignment against the appliance model before concluding which subcomponent has failed.
- Delayed or repeated âignition cycles (long â¤glow time or âŁcontinuous clicking of⢠the gas valve)
- Weak or no glow⤠from the âignitor during the startup sequence
- Yellow, liftingor sooty flame indicating incomplete combustion â¤or orifice restriction
- Oven or burner âfails to reach set â¤temperature despite normal thermostat operation
- Visible cracking, blisteringor â˘contamination on the ignitor surface
| Item | Description |
|---|---|
| Weak glow / long preheat | Indicative of degraded hot-surface element or high-resistance connections; confirm continuity and compare current draw to service specification. |
| Yellow âor sooty flame | Consistentâ with partial orifice âŁblockage,â incorrect orificeâ sizeorâ air-fuel imbalance; âŁinspect orifice and pilot/air shutters⣠and perform flame pattern test. |
| Valve click without ignition | may indicate ignitorâ not reaching required current to â¤open valve or intermittent wiring; isolateâ electrical checks from fuel delivery checks to pinpoint fault. |
Visual inspection and electrical measurement are⤠the primary diagnostic actions: examine the ignitor forâ surface damage, verify secure, corrosion-free connectors, then measure continuity and, where safe and âpermitted, operationalâ current or voltage while cyclingâ the â¤unit to observe glow intensity and timing. âFor orifice-related issues,remove and inspect for debris orâ deformation,compare the installed orifice to manufacturer sizing for⣠the âmodel,and confirm flame shape and stability under live conditions. Practical examples include an oven that glows but never opens the gas valve (suggesting âinsufficient ignitor current or⣠poor connection) versus a bright glow followed by âŁa yellow, sooty âŁflame (suggesting orifice restriction or incorrect air âŁmixture); use these patterns, combined with electrical and mechanical checks, to determine âwhether the entire assembly must be replaced or a targeted repair is sufficient.
Replacement, Compatibilityand StepâbyâStep Installation Procedures â¤for the 316536623 Frigidaireâ Ignitor/Orifice âAssembly
The 316536623 Frigidaire Ignitor/Orifice Assembly combines a gas metering orifice withâ the ignition element into a single âŁserviceable unit; âthe ignitorâ creates the spark or heat âsourceâ while the matched âorifice controls⢠fuelâ flow so the burner achieves⢠the correct flame shape and heat output. Compatibility is determined by three physical and functional attributes:⣠the mounting pattern and bracket alignment, âŁthe electrical/ignition connector⤠type and wiringandâ the⣠orifice⢠bore size keyed to the appliance’s gas⢠type⤠(Natural or âLP). For example,installing aâ unit with âthe âŁcorrect connector and bracket but an incorrect orifice bore willâ produce a weak or noisy flame and can trigger flame-failure sensors even though the ignitor itself functions normally.
- Shut off gas andâ electrical power to the appliance before beginning âŁwork.
- Access⣠the burner area by removing⤠the rear â¤or bottom service panel and note the⣠ignitor wiring and ground locations.
- Disconnect the ignitionâ lead(s) and removeâ the mounting screws/bracket holding the old⢠assembly; retain any gaskets or heat shields⣠that must be reinstalled.
- compare the new 316536623 âŁFrigidaire âIgnitor/Orifice â˘Assembly to theâ old unit for orifice bore, connector typeand mounting orientation; transfer or replace gaskets⤠as required.
- Install the⤠new assembly, secure fastenersâ snugly (avoid⣠overâtorquing), âreconnect the ignition â˘lead(s), restore gas and power, then perform ignition and leak â¤testsâ while observing flame pattern and sensor⤠response.
| Item | Description |
|---|---|
| Part number | 316536623 – integrated ignitor andâ matched âburner orifice |
| Connector | Low-voltage ignition⤠lead/ground; âverifyâ pin count andâ connector style against âthe appliance |
| Mounting | Bracket-mounted with 1-3 screws depending on model; orientation critical for proper electrode position |
| Orifice | OEM-specific bore size; matched to Natural âor LPâ service and frequently enough specified on the appliance â¤parts sheet |
After installation,verify correct operation by observing ignition timing,flame stability â(sharp blueâ cone with âminimal yellow),and that âflame âsensors detect steady combustion; if⢠ignition occurs but flame is unstable,recheck orifice size,sealing âŁsurfaces,and air⣠shutter/primary air settings. If there is no spark or sustained flame,⢠traceâ the ignition circuit with a âmultimeter for proper voltage âŁand âcontinuity, inspectâ the safety valve and wiringâ harness for damageand confirm the âreplacement â¤assembly’s connector and orientation match⣠the original -â replacing the orifice or ignitor alone without addressing a âmismatched mount or wiring will not resolve functional faults.
Q&A
What is the 316536623 Frigidaire â¤Ignitor/Orifice Assembly?
The 316536623⤠is an OEM replacement part for certain Frigidaire gasâ ranges/ovens. It âcombines the gas orifice â˘(jet) that âmeters âfuel to a burner â¤and â˘the â˘ignitor component that lights the gas (either a spark electrode or a glow-type ignitor âdepending on the appliance). The âassembly is designed to replace âthe original factory part for safe and reliable ignition.
How⤠do I no if this part âŁis compatible withâ my Frigidaire appliance?
Check the compatibility by âmatching the appliance model number (usually on a tag inside the oven door frame,behindâ the â¤storage â¤drawer,or⢠on the back of the range) to the part listing on frigidaire’s parts site or a reputable partsâ dealer. If you â˘are unsure, provide the full⣠model â¤number âto the dealer or technician; âŁthey can confirm whether 316536623 is the correct replacement.
Whatâ are common â˘symptoms that âindicate the ignitor/orifice assembly is failing?
Common symptoms include: burners that won’t light or take a long âtime to light, weak â¤or yellow/sooting flames,â continuous clicking without ignition (for spark systems), an oven ignitor that glows but the⣠burner valve never opens, â¤or visible damage/corrosion at the ignitor/orifice.Any repeated ignition failures or abnormal flame characteristicsâ suggest inspection/replacement.
How can⢠I test âthe ignitor/orifice assembly to âŁdetermine if it’sâ bad?
Basic checks: visually inspect⤠for cracks,carbon build-up,or⣠corrosion; verify the ignitor glows or the electrode produces a visibleâ spark â¤when the burner is calledâ for.⣠For more⢠definitive testing:⤠for spark-style ignitors check continuity of â˘the electrode circuit with a multimeter (power off); for glow-type oven ignitors you can measure current draw with the circuit powered (requires proper â˘test equipment and âsafety precautions) â- if the âignitor glows â¤but does not draw sufficient current theâ valve may not open. If you’re not agreeable with electrical/gas tests, have a qualified â¤technician perform diagnostics.
Can I â¤install the 316536623â myselfor should I hire a technician?
Minor mechanically skilled âŁowners can âperform âthe swap if âthey are â˘comfortable working safely with â˘gas âand electricity: turn off electrical power and âgas âsupply, âdisconnect the appliance, â˘follow the manufacturer’s removal and â˘installation steps, âand perform a gas-leak test after installation. However, becuase incorrectâ installation can cause gas leaks, fireor carbon monoxide risks, hiring a⢠qualified âappliance technicianâ is recommended-especially if any âgas-line adjustments or orifice changes â(natural âŁgas⤠â â˘LP) are needed.
Does the â¤assembly come with the âcorrect orifice size for natural gas vs.LPâ (propane)?
Orifice sizes⣠differ between natural gas âand LP. Some replacement assemblies are supplied specifically for one fuel type or include an alternate orifice; others require you to order the correct fuel-specific âorifice separately. Always confirm the fuel type â¤of your appliance and use the orifice size specified by Frigidaireâ for that fuel.⤠Converting between fuelsâ should⢠be doneâ with the⣠correct parts and by âa⢠qualified⤠technician.
What are the basic âsteps to replace the âŁignitor/orifice assembly safely?
Typical safe replacement⢠steps: 1) Turn off â¤the range’s powerâ and closeâ the âŁgas⤠shutoff valve. 2) Remove the burner grates and drip pans (or the âoven access panel for âoven ignitors).3) unplug⢠the connector to the ignitor and remove mounting â˘screws/fasteners holding the assembly. 4) Install the new assembly, secure fasteners, reconnect wiring (ensure correct, snug⣠connections)and reinstall panels. 5) Turn on gas âŁand performâ a soap-and-water leak test at the â˘connection points.6) Restore power âand test ignition. If you detect leaks or abnormal operation, shut the gas off and â¤contact a technician immediately.
After replacing the assembly, the burner still won’t light or the flame isâ weak⣠– what should I â˘check next?
first⣠confirm the gasâ supply and shutoffâ valve are openâ and theâ connection isâ leak-free. Check that âthe correct orifice for your fuel type is installed⤠and that the ignitor is correctly positioned andâ clean.â For sparkâ systems⢠verify the spark is striking the electrode;⣠for glow ignitors confirm it reaches full-brightness. Also inspect the burner ports for clogs and the manifold/valve⢠for proper â¤operation. If the ignitor â˘works but⤠the valve does not open, âthe gas valve or control module⤠mayâ be faulty and should be⣠inspected by aâ technician.
