Functionâ and Role of the Ignitor/Orifice inâ Gas Deliveryâ and Ignition⤠Control
The 316536610 Frigidaire Ignitor/Orifice Assembly combines the ignition element and the calibrated gas orifice into a single service component that controls both ignition energy deliveryâ and metered fuel flow to a burner. âThe assembly’s ignitor (either a hot âsurface or spark-typeâ depending on the model) provides the required âenergy or signal to the gas valve or â˘spark⢠module to initiate combustion, while the⢠orifice determines âvolumetric flow at a⣠given manifold â˘pressure; mismatched orificeâ sizing or⣠degradedâ ignitor⢠performance alters flame shape, heat⤠outputand combustionâ stability. Technicians mustâ match â˘the orifice orifice⤠number andâ fuel type (natural gas vs. LP) to theâ appliance’s specifications and verify valve/manifold pressure â¤when diagnosingâ yellow flames, âŁweak heat,⣠or delayedâ ignition, since thoseâ symptoms commonly indicate either incorrect⢠flow characteristics or insufficient ignition energy rather than an electronic control fault.
In operation the ignitor and orifice interact with the⢠gas valve and âŁmanifold regulator: the ignitor provides the timing/energy for ignition while the orifice sets the steady-state gas volume available when the valveâ opens. Typical maintenance⣠and âreplacement steps âinclude verifying the ignitor’s resistance/current draw, confirming the orifice aperture corresponds âŁto the appliance’s gas type, ensuring proper alignment and⢠sealing of the assemblyand⤠performing a leak and combustion â˘checkâ after installation. Practical examplesâ include⢠replacing a brittle âŁor high-resistance ignitor to resolve intermittent no-light conditionsorâ swapping to âthe correct orifice size when conversion⣠toâ LP results in⣠sooting or excessive flame length; correct â˘installation and measurement of manifold pressure and flameâ characteristics are necessary to ârestore safe, efficient operation.
- Key behaviors: ignition energy vs. âvalve âŁactuation timingand⣠orifice-dependent flow rate at specifiedâ manifold pressure.
- Common symptoms: weak flame, yellow tipping, delayed ignition,⢠or continuous sparking âpoint to orifice/ignitor mismatch or degradation.
- Compatibility â˘checks: confirm fuel typeorifice stamp/size, ignitor resistance/specand connector type before replacement.

How the 316536610 Frigidaire Ignitor/Orifice Assembly Operates Inside Frigidaire appliances
The â 316536610 Frigidaire Ignitor/Orifice Assembly combines the ignition element and the fixed gas metering orifice into⢠aâ single service component that mounts â˘directly at the burner port. In operation, the⢠ignitor provides⤠the energy-either a hot-surface glowâ or timed spark depending on the appliance ignition system-to initiate âcombustion just as the gas valve opens; the orifice then meters the gas flow to create the correct jet and flame shape for stable combustion. Thisâ assembly must match the appliance’s intended fuel type and burner geometry:⢠orifice size and placement âŁestablish⤠the âŁdelivered BTU and flame profile, while the ignitor’s electrical âŁcharacteristics must be compatibleâ with the âoven or range control circuitry forâ reliable spark/heat timing and flame establishment.
Technicians⤠diagnoseâ assembly issues by âobserving ignition timing,⤠flame pattern, âŁand gas⤠flow behaviorand by performing electrical checks on the ignitor and pressure/orifice inspections for blockages or incorrect sizing. Replace the assemblyâ with the correct âŁpart number or anâ OEM-equivalent sized orifice when converting between natural gas and LP; simply fitting an ignitor without âcorrecting orifice â˘size⣠or âregulator settings can produce weak flames, yellow tippingor unsafe combustion. â¤During installation verify alignment, secure mounting, correct âŁgas-seat sealing,â and performâ aâ leak test before operating the appliance underâ normal load conditions.

Common Failure Symptoms âŁand âDiagnostic Tests for Ignitor/Orifice⣠Malfunction
The 316536610 Frigidaire⣠Ignitor/Orifice â¤Assembly combines the âŁignition element âŁand the gas metering orifice into âa âsingle âŁservice item that restores the intended ignitionâ timing and flame geometryâ for specific Frigidaire gas ranges â¤and â¤ovens. The ignitor portion (glow â˘orâ spark type depending on the model) provides the necessary thermal or electrical stimulus to âopen the âgas valve and initiate combustion, whileâ the orifice determines gas flow rate âand mixes with incoming air to⣠produce a stable flame. Compatibility is determined by orifice size, mounting configurationand⣠ignition type; using the correct âassembly preserves the appliance’sâ designed gas flow â¤characteristics and preventsâ improper air-fuel ratios that causeâ weak, liftingor yellow flames.
Common failure modes include â˘open or intermittently âŁconductive ignitor elements, cracked or glazed ignitor⣠surfaces thatâ fail⤠to reach operating temperatureand partially obstructed orifices that reduce flow. Technically useful diagnostic actions include âŁa visual inspection for damage âor soot, a cold-resistance/continuity check of âŁthe ignitor â˘with a âmultimeterand⢠a live-voltage check at the ignitor âterminals during the start cycle to confirm proper drive voltage.Practical examples: an open circuit âreading on the ignitor âusually indicates replacement; delayed ignition with normal ignitor continuity suggests an orifice restriction or lowâ gas pressure and may require cleaning the orifice or verifying manifold âpressure with a manometer. When⢠testsâ are inconclusive,⤠swapping with a known-good assembly⤠or consulting the model-specific service âŁmanual for specification values yields the most reliable diagnosis.
- No ignition or⢠long ignitionâ time – test ignitor continuity and⢠verify âdrive voltage during the start cycle.
- Weak,yellow,or lifting âflame – inspect and clean/replace the⤠orifice; check manifold gas pressure.
- Intermittent operation or cycling â-⢠lookâ for cracked/glazed ignitor â¤surface or loose electrical connections.
| Item | Description |
|---|---|
| Ignitor continuity | Cold resistance should show a closed âcircuit; an open reading indicates a failed ignitor âelement ârequiring⤠replacement. |
| Orifice condition | Orifice must be free of debris âŁandâ correct size for the model; partial obstruction⢠causes delayed ignition or weak flame and⤠requires cleaning or âreplacement. |
Compatibility,replacement Considerations,and Installation Procedures â˘for âthe â¤Assembly
The 316536610 Frigidaire Ignitor/Orifice Assembly combines the spark or hot-surfaceâ ignitor function with the matched orifice â˘that⤠meters gas to the burner,so both ignition energy â˘and fuel flow are coordinated for the intended appliance. In âoperation the ignitor â¤must present the correct electrical behavior (sparkâ voltage or hot-surface resistance and warm-up)⤠while the orifice provides the designed orifice âdiameter and thread fit for the manifold;⣠mismatching either component alters flame⣠shape, burn rateand â¤ignition⢠reliability. Technicians should verify âthatâ the⢠assembly matches the appliance model and the installed gas type (natural gas or LP) because orifice â¤sizing and manifold pressures differ between service configurations and can require a different⤠orifice âwithin the same mounting envelope.
- confirm model and part number against â¤the âapplianceâ parts list before disassembly.
- Deadâfront the appliance: shut off gas supply and disconnect electrical power prior â˘to work.
- verify orifice identification and gas type; do not â˘interchange natural and LP orifices without conversion parts.
- Inspect ignitor for correct â˘connector, mounting orientationand electrode/gap or resistance values before reuse.
- Use correct thread sealant where specified and torque mounting⢠fasteners to manufacturer values âto avoid distortion⢠of the orifice/ignitor mating.
- After installation, perform a pressure/leak test and an ignition sequence check at each burner toâ confirm stable flame and proper flame sensor response.
Replacement practice: â¤remove the old assembly and⤠examine the manifold port for damage or debris, measure ignitor continuity orâ resistance against service data, â˘and compare theâ physical orifice marking âto⣠the replacement part. during installation, align the ignitor so the electrode gap and heat-sensing element are positioned as the original part; improper spacing⣠or rotated â˘orientation can cause delayed ignition or nuisance âlockouts. For retrofit or conversions, obtain the orifice size and manifold pressure specifications from⤠the appliance documentation and document the change on âthe appliance for future service records.
