316536623 Frigidaire Ignitor/Orifice Assembly is a combined gas ignition and metering componentâ designed for use in Frigidaire gasâ cooking appliances.The assembly pairs an ignition element (which may be a spark electrode or a hot-surface ignitor depending on the appliance design) with a precision orifice that meters the⤠gas flow to the burner; together these â˘parts âcontrol the delivery âŁand initial combustion of⣠gas at a specific burner or oven port.
Within the appliance the ignitor/orifice assembly interfaces directly⤠with the gas manifold and gas valveand it operates in the ignition sequence coordinated by the range/oven control module⣠or thermostat. Proper⣠operation requires correct orifice sizing for âthe appliance’s rated BTU output and âŁreliable ignition timing âso that gas âflow is established only while a⢠valid ignition source isâ present; the assembly therefore works alongside safety items such as flame sensors, thermocouples, pressure âregulatorsand âcontrol relays to ensure sustained, safe combustion âŁand correct flame characteristics.
in this article youâ will â˘find âa âŁtechnical overview of how the 316536623 âassembly functions, â¤guidance on compatibility and orifice sizing considerations, common⤠failure symptoms to watch forand diagnostic âapproaches a technician or âexperienced appliance owner can use toâ isolate ignition versus âfuel-delivery problems. The piece also outlines practical replacement considerations – including matching part âspecifications and âbasic installation and safety âprecautions – soâ readers can evaluate repairâ options with anâ understanding of the electrical, mechanicaland⤠gas-system interfaces involved.

Function and Role of the Ignitor/Orifice assembly in Frigidaire⢠Gas â˘Burners
The 316536623 Frigidaire Ignitor/Orifice âAssembly combines the ignition electrode and â¤a fixed gas meteringâ orifice into âa single serviceable module for⤠Frigidaire gas burners.When the â˘control circuit commands a burner, the gas valve opens and âŁthe⤠orifice meters a precise volume of gas to the burner port while the ignitor generatesâ a high-voltage spark across a âdefined gap to ignite⤠the air-fuel mixture. The orifice diameter sets the expected mass flow⢠(and thus nominal BTU output) forâ that burner position, whileâ the ignitor’s electrodeâ material, gapand mountingâ position determine ignition reliability âŁand flame propagation. This assembly is used on models⣠specified for that part number and⣠must matchâ the appliance’s â¤fuel type (natural gas vs. LP)⤠and⤠burner âgeometry to maintain designed combustion behavior.
In service,technicians evaluate the assembly by observing spark location âand intensity,checking the orifice for carbon build-up orâ foreign debris,and verifying continuityâ and âŁresistance of the ignitor circuit. Typical field symptoms indicating replacement include sustained sparking without ignition, slow⢠or delayed ignition that produces poppingor visible flame instability at the burner ports; âthese symptoms can stem from aâ clogged orifice, electrode erosionor connector/wiring faults. â˘Installation requires correct orientation,secure electrical connections,andâ confirmation that⤠the â˘gas valve and⣠safety interlocks function âŁcorrectly before returning the appliance to service.
- Sustained sparking with no â¤flame
- Delayed ignition or loud ignition pop
- Weak, âyellowor uneven flame across burnerâ ports

How the 316536623 Frigidaire Ignitor/Orifice Assembly Works â¤Inside the âAppliance
The 316536623 Frigidaire Ignitor/Orifice Assembly combines a heating ignitor element and a gas metering orifice into a single service âcomponent that mounts at the burner port. During the⣠appliance â¤start sequenceâ the control module⤠applies voltage to the ignitor so it reaches ignition⤠temperature or produces a spark, then the gas valve opens and the orifice meters the volume and âŁvelocity of gas delivered âto the burner. proper operation depends on the⣠ignitor reaching âthe correct temperature/current draw to reliably ignite the gas as â˘it exits the âorificeandâ on the orifice diameter being matched to the burner and gas type (natural âgas or LP) to maintain stable âcombustion and correct â¤heat output.
- Common failure symptoms: delayed⤠ignition,â continuousâ sparking, weak orâ no glow from the ignitoror uneven flame that âŁsuggests a⤠clogged or mismatched orifice.
- Practical âŁchecks: âŁinspect the orifice for debris, verify mechanical fit and thread size to the manifold, confirm ignitor continuity and current draw â¤against the appliance specificationand ensure the part is⣠specified for the correct gas type.
- Compatibility considerations: use the OEM part or âan exact equivalent⤠to preserve flame characteristics and safety interlocks;⣠substituting a âŁdifferent orifice size âcan cause incomplete combustion or â˘trigger safety shutoffs.
Functionally, the assembly is part of âthe ignition circuit andâ the gasâ delivery subsystem: the ignitor â˘provides theâ energy to start combustion, while the orifice sets the â¤gas throughput so the resulting flame is within design parameters. In practice this means⢠technicians should verify both electrical andâ gas-side attributes when âdiagnosing ignition faults â- for âexample, anâ ignitor that glows⣠but the âŁburner still does not light can âindicate a blocked orifice or faulty gas valve rather than an electrical fault. When replacing the unit, confirm theâ mounting âorientation, manifold port âŁalignmentand that the replacement 316536623 â¤Frigidaire Ignitor/Orifice⤠Assembly matches the appliance’s gas type and controlâ interlocks to âavoid combustion instability or safety trips.

Common Failure Symptoms and Diagnostic Indicators for Ignitor/Orifice Malfunction
The 316536623 Frigidaire â¤Ignitor/Orifice⢠Assembly⢠combines âthe glowâ ignitor element with the gas⢠metering orifice to initiate âand sustain combustion in compatible Frigidaire gas ovens and ranges. The ignitor must heat to a specific temperature to allow gas to ignite safely,⢠while âŁthe â˘orifice âprecisely meters âŁfuel flow to each burner; deterioration of either element changes ignition timing and flame shape. This assembly is an âOEM-style replacement that plugs into the âoven’s burner system, but technicians should âconfirm fit against the appliance â¤model number âand serviceâ documentation before installation because orifice size and mounting orientation vary between models and production runs.
Diagnosing a malfunction requires correlation of electrical, visualand combustion indicators rather than relying on a single symptom.⣠Perform a âvisual inspection for cracks, glazingor carbon buildup on the ignitor and check the orifice for debris or⢠deformation; use a multimeter to verify continuityâ and compare measured resistance and current draw against the manufacturer’s service spec. Practical indicators include prolonged glow time or⤠weak orange glow (ignitor aging), delayed âignition or repeated â˘clickâ cycles (insufficient âignition energy orâ clogged/undersized orifice)and yellow, sootyor unstable flames (incorrect fuel flow or partial obstruction). For safety and accuracy, verify gas supply pressure and valve âoperation when flame shape suggests improper meteringand replace the assembly if electrical resistance, glow behavioror physical damage fall outside the appliance’s specifiedâ limits.
- Ignitor does not glow or shows intermittent glow
- Delayed ignition or multiple ignition attempts (clicking)
- Yellow, sooty, âor uneven flame pattern
- Visible carbon⤠buildup or a âŁpartially âŁblocked orifice
- Burner lights but extinguishes or has reduced flame height
| Item | Description |
|---|---|
| No glow | Open filament or failed electrical connection;⣠confirm continuity and connectorâ integrity. |
| Weak/slow glow | Aging ignitor with increased âresistance or â¤reduced current âdraw; causes âdelayed ignition. |
| Sooty/yellow flame | restricted orifice, incorrect orifice sizeor improper airâtoâgasâ ratio affecting combustion quality. |
| Intermittent ignition | Loose wiring, marginal⣠ignitor performance, â˘or valve⢠timing/pressure fluctuations â˘that prevent consistent ignition. |
Compatibility âMatrix,Replacement Considerations,and Step-by-Step Installation â¤& Troubleshooting
the 316536623 Frigidaire Ignitor/Orifice Assembly combines the ignition element âŁand theâ gas metering orifice into a⤠single serviceable unit that controls both the âinitiation and â¤the âŁquantity âofâ gas delivered to a â¤burner. the ignitor âprovides the energy (either a spark or hot surface depending on the⣠appliance design) to ignite the gas,⤠while the orifice sets⤠the volumetric flow⣠and therefore the⢠flame size and â¤combustion âcharacteristics. Swapping assemblies between different Frigidaire models âcan change âthe orifice drill size and alter pressure/flow behavior, so use the exact part number or consult the model’s service âŁliterature to ensure correct gas type (natural âŁvs.LP)â and orifice sizing; incorrect matching can produce weak flames, âdelayed ignitionor incomplete combustion symptoms such as yellow tippingâ or âsoot âdeposition.
Replacement â¤and⢠troubleshootingâ require basic tools, a multimeterand adherence â¤to safe gas-handling practice: shut off electrical power and gas⢠before disassembly, verify ignitor continuity per âthe service manualand inspect the orifice for debris or incorrect sizing when performance is degraded âor after a conversion. After installing a replacement assembly, perform âŁa leak test on fittings, verify stable blue â˘flames at full and low settingsand recheck wiring and valve operation if ignition problems persist; âif flame remains erratic despiteâ a confirmed âgood ignitor⣠and correct orifice, the gas valve/regulator or âcontrol electronicsâ should be evaluated next.Practical examples: âreplacing the assembly is common when a burner exhibits long ignition⢠times or the flame lifts at low inputand âconfirming the orifice drill âŁmatches the⢠appliance⤠label prevents âŁover- or under-firing after a repair.
- Pre-checks: power/gas off, visual â˘and continuity test of ignitor.
- Removal/Install: â˘remove access⣠panel,â unfasten bracket, swap assembly, confirm orifice orientation and⢠tightness.
- Post-install: leak test, observe flame color and stability, verify low/high settings.
- Troubleshoot further by checking valve continuity, regulator pressureand control board outputsâ if âsymptoms remain.
