316237805 Frigidaire Ignitor Orifice⤠Assembly is a combined gasâmetering and ignition component used inâ Frigidaire gas cooking â¤appliances. The assembly typically âincorporates a precision orifice⤠that meters fuel flow to a burner and âŁan ignition element (such as a glow ignitor or spark electrode, depending on â˘the appliance) that initiates combustion. As â¤a⣠discrete service part, it is indeed designed to mount atâ the burner/manifold interface⣠and to meet the dimensional, flow and electrical⢠characteristics required by the originalâ equipment.
Inside an appliance the ignitor⣠orifice assembly interfaces directly with the gas manifold, burner head, âŁthermally or electronically controlled gas valve, âŁandâ the âappliance control system.It determines the local âgasâ flow rate and provides the ignition energy⣠or spark timing required for âŁstable âŁflame establishment, so it affects combustion quality,⢠heatâ output and safety interlocks (such as, flame sensing and âvalve shutoffâ logic). Its correct function thus depends on proper âorifice sizing, unobstructed passages, secure electrical âŁconnectionsâ to the âcontrol board âor transformerand⤠compatible mechanical mounting âŁand sealingâ at the⤠manifold.
In âthe article that follows you will find a technical overview of the part’s function and key specifications, guidance on âhow to verify compatibility âwith âspecific Frigidaire models (including â˘what to check onâ orifice â¤size, thread, electrical ratings and mounting),⢠common failure symptoms to⣠recognize (no ignition, âdelayed or intermittent â¤ignition, weak or yellow flame, âvisible damage or clogging), diagnostic â¤approaches a technicianâ can useand â˘practical replacement considerations such as matching orifice and ignitor â˘characteristics, sealingâ and mounting best practices,â and postâreplacement verification steps. The focus is on âproviding the technical â˘context needed to diagnose, assess âcompatibilityand plan a safe,â reliable repair or replacement.

Function and Operationalâ Role of âthe Ignitor Orifice Assembly within the Burner and Ignition System
the 316237805 Frigidaire Ignitor Orifice Assembly serves âŁasâ a precision gasâmetering and âignition interface⤠component within a Frigidaireâ gas burner assembly. It combines a small-diameterâ orifice that regulates â¤the gas flow with a mounting/seat that positions the â˘ignitor or spark electrode at the correct distance from theâ burner âport. â¤Proper orifice sizing and alignment are criticalâ to achieve the correct airâfuel ratio at the moment of ignition; ifâ the orifice is to âŁlarge or too smallor if the âignitor-to-port spacing âŁis âoff, the burner will show delayed ignition, unstable flame,â or soot formation. This assembly is supplied as an OEM replacement for specific Frigidaire ranges and shouldâ be matched to the appliance model⢠and fuel type (natural gas or LP) âduring service or replacement to maintain designed combustion characteristics.
- Primary roles: gas metering, ignitor positioningand âsealing the âgas passage.
- Common service symptoms: slow ignition, repeated safety lockouts, yellow or lifting flame,â or visible soot⢠around the burner port.
- Practical check: â¤inspect for blockage, confirm orifice size⢠and orientationand verify ignition â¤timing and electrode voltage when diagnosing.
| Item | Description |
|---|---|
| Function | Regulates fuel flow to the ignition zone and maintains correct âignitor geometryâ for reliable âspark or âglow ignition. |
| Interface | Mounts to the burner tube/valve outlet and locates the ignitor or electrode⣠relative to the burner âport. |
| Compatibility | Intended as an OEM⤠replacement for select Frigidaire âgas ranges; verify appliance model and fuel type before installation. |
| Failure âmodes | Blockage,incorrect orifice sizing,and misalignment causing slow⢠ignition,weak flame,or safety shutoffs. |
In service practice, technicians âŁuse the ignitor orifice assembly as both a diagnosticâ focal point and a field-replaceable part.⢠For example, âa range exhibiting long ignition intervals and occasional flameouts frequently enough responds toâ cleaning or replacing the orifice assembly rather âŁthan replacing⣠the entire valve or ignitor; conversely, if the ignitor does not reach proper âvoltage or⤠temperature, âreplacing theâ orifice alone will notâ cure the â¤problem. During replacement, maintain correct torque on fittings, avoid deforming⢠the orifice or seatand⣠perform an â˘operational â˘check: observe ignition timing, flameâ shapeand âperform a pressure/leak check at the connection to âensure theâ assembly restores the designed burner performance.
How the 316237805 Frigidaire Ignitor Orifice⢠Assembly Integratesâ with Gas⢠Flow, Spark Timingand Control Electronics
The â˘316237805 Frigidaire ignitor Orifice Assembly integratesâ a metered gas orifice with an ignition electrode in a⣠single âŁmounting âthat physically and â¤functionally couples the burner gas â˘flow to the ignition system. The orifice controls volumetric flow and sets the local air/gas ratio at the point the electrode introduces the spark, so correct â¤orifice size and â¤precise electrode placement determine flame size, stabilityandâ combustion efficiency. in operation the oven â˘or range control opens the⤠gas valve,and the ignition moduleâ or âŁcontrol boardâ issues⣠high-voltage pulses to âthe electrode timed to coincide with gas flow so a combustible mixture is present at the spark site; flame sensing (ionization or a thermocouple in some âŁsystems) then confirms ignition⢠and allows the control electronics to stop sparking and modulate âŁthe valve as required.
- Orifice â˘metering – â¤setsâ gas flow and burner output; must matchâ appliance calibration.
- Electrode position and gap – âŁdetermines where sparks⤠form relative to⣠the gas jet; small â¤positional shifts affect reliability.
- Mounting and sealing – aligns with the valve outlet and provides a gas-tight âconnection to prevent leaks and ensure repeatable flow.
- Electrical interface – âcompatible with the appliance’s ignition module voltage and âpulse⢠timingâ characteristics.
Timing and control⢠electronics coordinate three functions: valve âactuation,spark generation,and flame detection. Typical sequences âstart âwith the control energizing the valve, instantlyâ followed by timed ignitionâ pulses; successful flame establishment is detected by flame rectification or a temperature sensor, which signals the control to stop pulsing and maintainâ the valve â¤state. In âŁpractical troubleshooting,⣠a partially clogged⣠orifice⣠produces âdelayed ignition and a weak flame, while a⢠misaligned âŁor damaged electrodeâ yields erratic sparking or continuous⣠arcing to the â¤burner base; âboth conditions can cause control⣠lockouts. Replacing theâ assembly âwith the correct part and checking electrode gap, mounting alignmentand electrical continuity restores the âdesigned interaction between gas flow, spark timingand âŁthe appliance’s control electronics.

Common Failure â¤Symptoms and Diagnostic Indicators for âignitor â¤Orifice⤠Assembly Malfunction
The â˘316237805 Frigidaire Ignitor Orifice âAssembly combines the orifice that meters gas flow with the ignitor positioning hardware; its function is to deliver a steady, properly directed gas jet to the ignitor so⢠the electrode can reliably produce a spark or maintain a hot surface glow. When the assembly is compromised-by a clogged orifice,misalignment,cracked insulation on⤠theâ ignitor,or⣠degraded⣠mounting-the ignitor may â¤take longer toâ light,fail to sustain a âflame,or cause â¤repeated valve âcycling. This â¤part isâ used on Frigidaire ranges and cooktops that share the same burner geometry and âconnector interfaces; technicians should crossâreference appliance model numbers and â˘dimensional fit rather than assuming â¤universal interchangeability⤠across unrelatedâ models.
Diagnostic indicators combine â¤sensory checks, visual inspection,⢠and simple electrical measurements. Techniciansâ commonly observe extended ignition time, visible arcing or â¤weak⢠glow from the ignitor, soot or⢠carbon buildup⢠near the orificeor⢠the presence of a gas odor without ignition.⤠Use a multimeter to check for continuity and consistent resistance across the ignitor leads-an open circuit or wildly fluctuating resistance indicates internal⢠failure-while âalso verifying thatâ the orifice path is free of debris and that the ignitor is correctly aligned with the gasâ jet. Practical troubleshooting also includes swapping the assemblyâ with a known-good unit or measuring ignition âdwell⤠time during start-up to distinguish control board or valve faults fromâ a â˘true orifice/ignitor assemblyâ failure.
- Delayed ignition or long glow period before flame establishes.
- Intermittent âŁsparking, âcontinuous clickingor no ignition at⣠all.
- Gas âodor â¤without ignitionor â¤flame extinguishing soon after lighting.
- Visible soot, carbon deposits, â˘or physical damage to the orifice/ignitor.
- Multimeter shows open â¤circuit âor inconsistent resistance across ignitor terminals.
| Item | Description |
|---|---|
| Visual⤠inspection | Check for clogged orifice, carbon buildup,⣠cracked ceramic, bent electrodesand correct alignment to the burner port. |
| Electrical check | Measure continuity and steady resistance âon the ignitor leads; intermittent continuity or open reading indicates replacement. |
| Operational⤠behaviour | Record ignition time and valve cycling; long dwell times or repeated â¤valveâ attempts point to âŁreduced gas delivery or weak ignitor output. |
Compatibility,Replacement Considerations,and StepâbyâStep Installation Proceduresâ for Affected Frigidaire Models
The 316237805 Frigidaire Ignitor Orifice Assembly is a precision component that⣠both âmeters gas flow to the burner andâ locates the âignitor relative to the burner head. In operation theâ orifice determines the fuel flow rateâ while the assembly’s physical alignment and sealing surfaces ensure consistent ignition timing and stable flame âshape; âwear, partial blockageor âincorrect orifice size can produce delayed ignition, intermittent spark transferor⣠an âunstableâ (yellow or lifting)â flame. Compatibility depends on the mounting flange, thread sizeorifice port diameter,â and the â˘electrical harness interface-verify â¤the appliance model and gas type⢠(natural gas â¤vs⤠LP) against the OEMâ parts list before substituting âparts to avoid â˘mismatched flow characteristics or improper sealing.
When replacing the assembly, inspect âŁmatingâ surfaces, the ignitor electrode⤠gapand the associated gasket or bracket; mismatched gaskets or damaged â˘electrodes are common secondary failure points that can persist after swapping the orifice. Followâ a controlled⢠procedure and perform âleak and flame-shape checks afterâ reassembly: â shut offâ gas and electricalâ power, remove access panels to expose theâ burner/valve âarea, disconnect the ignition harness, remove the burner head to access âthe orifice, replace the orifice assembly and âany recommended gaskets, âtorque fasteners to the applianceâ specification, reconnect the âharness, restore â¤gas⣠and power, then verify ignition sequence and perform a⣠soap-leak âtest âat â¤the valve and orifice⤠fittings.
- Safety first: shut off gas supply and isolate electrical power âŁbefore âŁbeginning work.
- Remove cooktop/oven accessâ panels and the burner âŁhead to access the orifice assembly.
- Disconnect âthe ignitor harness â˘and unthread the old orifice assembly; inspect for⢠debris â¤and corrosion.
- Install new assembly ensuring⣠correct orientation, gasket seatingand proper torque; reconnect harness.
- Restore gas and power, then check â˘for âleaks and confirm stable, blueâ flame and consistent âŁignition.
