function and Role of âthe Ignitor/Orifice⤠Assembly in Gasâ Ignition,Flow â¤Regulation,and â˘Safety Controls
The 316536610⢠Frigidaire â˘Ignitor/Orifice âAssembly combines the â¤ignition â˘electrode and the calibrated âmetering orifice into aâ single replaceable unit that both â¤initiates combustion and controls the volumetric gas flowâ to a⢠burner. The ignitor portion provides the necessary energy – either â˘a high-voltageâ spark or a hot-surface element depending on the exact model – to⤠ignite âthe gas delivered through the orifice,â while the â¤orifice⢠diameter defines the fuel flow rate âand, together with⣠the âburner âŁport pattern, âŁestablishes the airâfuel ratio andâ flame characteristics. Technicians â˘should verify that the assembly matches the appliance model and⤠the intended fuel type (natural gas versus LP) as incorrect orifice sizing will alter manifold pressure ârequirements, produce a yellow or sooty flameand can cause ignition delays or incomplete combustion.
- Features and checks:â calibrated orifice bore, ignition electrode gap and insulation, mounting orientationand⢠electrical connector compatibility.
- Common failure symptoms: weak or âintermittent spark, delayed ignition (puffing), persistent gas odor before ignition, yellow or âlifting⣠flameor â˘repeated safetyâ lockout.
| Item | Description |
|---|---|
| Orifice âsize | Precisely meters gas flow; must match âappliance configurationâ and fuel type â¤to maintain correct flame and â¤emissions. |
| Ignitor characteristics | Sparkâ voltage or hot-surface resistance and electrode geometry – inspect for cracks, corrosionor incorrect gap. |
In practical troubleshooting âand installation, verify ignition â¤continuity and electrodeâ resistance withâ a multimeter, inspect the orifice for deposits or partial obstructionand observe âŁflame pattern under normal manifoldâ pressure. The ignitor/orifice assembly operates within the appliance’s control sequence and flameâsensing circuitry: âa failing â¤ignitor can prevent âflame â¤establishment and triggerâ the gas safety shutoff, while an⤠incorrect orifice can âoverload â¤the valve or force frequent adjustmentsâ to the regulator. When replacing this component, match the âŁOEM part number â˘and⣠confirm âthe fuel conversion requirements rather âŁthan relying on visual similarity alone; correct installation and torque of mounting fasteners and a clean orifice â˘bore are â¤often sufficient to â˘restore reliable ignition and⣠safe operation.
How the 316536610 Frigidaire âIgnitor/Orifice Assembly Works Inside the⢠Appliance: Ignition Sequence, Orifice Sizing,â and Thermal behavior
The 316536610 Frigidaire âIgnitor/Orifice Assembly combines â˘the ignition element and the âcalibrated âgas⤠orifice into a single âservice item that controls how fuel and ignition energy meet â¤atâ theâ burner.In operation the assembly⣠supplies a âcontrolled gas flow â˘through⣠the orifice while the ignitor provides the ignition energy (either a hotâsurface glow or spark, âŁdepending onâ the appliance design). The normal ignition sequence is: a control callâ for⤠heat,⤠valve â¤opening and gas flow through the⤠orifice, energizing of â˘the ignitor to create ignition energyand establishment of â˘a stable flame with feedback to the⣠control system â¤via âthe appliance’s⤠flameâsensing circuit.
- Callâ for heat:⤠control âenergizes â¤gas valve.
- Gas metering: orifice restricts flow to the rated BTU for â˘that burner.
- Ignition: ignitor generates heat or spark to ignite the gas/air mixture.
- Flame verification: sensor/thermocouple or electronic rectificationâ confirms flame and maintains valve position.
Orifice sizing governs the fuel flow rate and thus the steadyâstate⣠flame size and heat output; aâ smaller orificeâ reduces flow and combustion intensity, while an â¤oversize orifice⤠increases demand onâ the control system and can produce sooting âor incomplete combustion if âsupply pressure is unchanged. Thermal behavior of the ignitor itself affects ignition timing and longevity: hotter,⣠higherâmass ignitors take longer to reach âignition temperature and dissipate heat slower, while thin or degraded elements⢠may glow weaklyâ and cause âŁdelayed ignition or intermittent failure. For âtroubleshooting,â technicians compare gas⣠manifold pressure, measure ignitor current/voltageand inspect the orifice⤠for corrosion or debrisâ – a clogged⢠orifice will delay ignition, while âŁa pitted orifice alters flow characteristics and warrants replacement of âthe assembly â˘to restore designed performance.
| Item | Description |
|---|---|
| Orifice function | Calibrates gas flow to âburner âto achieve target BTU at specified supply pressure. |
| Ignitor behavior | provides ignition energy and exhibits a warmâup time and current draw useful for diagnostics. |
Commonâ Failure Symptoms and Measurement-Basedâ Diagnostics for Ignitor/Orifice Malfunction
The 316536610 Frigidaire Ignitor/Orifice Assembly combines the ignitor element and âŁgas orifice into a single serviceable unit that both initiates⣠combustion and meters the burner flow. In normal operation the ignitor heats or produces aâ spark (depending on design)â to ignite gas delivered through the orifice; the timing and energy of that ignition event must⢠match âthe gas valve and control â¤strategy used on â˘the specific⢠Frigidaire⢠range orâ oven model. Compatibility depends on mounting points, electrical connector typeand orifice sizing:â replacing⢠the part with the correct 316536610 assembly⢠preserves the original flow âcharacteristics and electrical interface,⣠whileâ substituting a mismatched assembly âcan cause slow ignition, improper flame shapeor control faults.
Troubleshooting focuses on symptom observation combined with measurement to separate âcontrol, wiring, ignitorand orifice issues. Visual âand functional symptoms to note⢠include⣠delayed light-off, repeated⣠clicking with no sustained flame, a weak or sooty (yellow)⢠flameor oven âtemperature âdrift; each symptom narrows the likely âcause. â¤Key diagnostic checks include measuring for proper control output during a heat call and â˘verifying ignitor continuityâ and heating behavior with a â¤multimeter or clamp metre. Perform electrical checks âŁwith âpower applied only for voltage/current verification (observe safe procedures) and perform resistance/continuity checks with âpower removed.⣠Practical examples: a control thatâ supplies line voltage âduring a â¤call but an ignitor that âdoes not draw expected heating current indicates a failed âignitorâ element, whereas correct ignitorâ current combined with a⤠weak flame points to a partially blocked orificeâ or â¤incorrect orifice sizing.
- Delayed ignition or⣠long heat-up time – check control⣠output and â¤ignitor âheating current.
- Continuous clickingâ without âflame – â˘verify valve drive voltage and ignitor integrity.
- Yellowâ or sooty⤠flame – inspect orifice for clogging or wrong orifice size â˘and check âair-to-gas ratio.
- Intermittent flame loss – examine wiring for shorts/opens and test connector continuity under âŁvibration.
| Item | Description |
|---|---|
| Control output during call | Measure âfor â˘expected drive⣠voltage/current when thermostat signals heat;⢠present output with no ignition usually implicates the ignitor or orifice. |
| Ignitor continuity/heating | Check continuity with power removed andâ heating current/temperature rise with power applied; an open â˘element or no heating âŁunder load indicates replacement. |
| Orifice condition | Inspect for debris, corrosionor⢠incorrect sizing; partial blockage reduces flame size and causes⣠sooting or delayed ignition. |
Compatibility, Replacement considerations, Step-by-Step Installation guidelinesand â¤Troubleshooting Procedures
The 316536610 Frigidaire Ignitor/orifice Assembly combines the spark/ignition electrode with the matched gas orifice that meters â¤fuel⣠to the âburner; together they determine ignition timing,â flameâ shapeand combustion quality. compatibility âŁdepends on theâ valve âŁoutlet thread, burner pan geometryand the appliance’s required orifice size⤠and gas type (natural gas or LP).⢠When evaluating replacement candidates, verify that the⢠valve stem diameter, mounting flange,⣠and electrical âconnector match theâ existing â¤assembly,â and â˘confirm that the orifice is sized for â¤the appliance’sâ gas pressureâ or conversion kit-mismatched orifice size or connector orientation will cause poor ignition,â delayed light-offor unsafe âŁcombustion characteristics.
follow âsafe, systematicâ procedures for replacement and troubleshooting: shut off gas and âelectrical power, remove burner grate and cap, document orientation and connector positions, unthread the assembly (retain gaskets), â¤install the⤠new unit with âŁcorrect alignment and torque, then â¤perform⤠a pressure/leak test and repeat ignition checks. Common failure â˘modes areâ cracked or fouled electrodes, obstructed orificeâ ports, loose âŁelectrical connectionsand improper orifice sizing after gas â˘conversion; âbasic⣠diagnostic checks include visually âinspecting the electrodeâ gap,â confirming⢠spark voltage âat the connector during a start â˘command,â and âverifying steady blue â˘flame characteristics under normal load. Use theâ checklist below for swift diagnostics and refer âto â¤the â¤table for key âtechnicalâ references before reassembly.
- no spark but control â¤clicks: check electrode â¤continuity/insulation and control module output voltage.
- Weak orâ yellow flame: confirmâ correct orifice size and gas pressure; inspect for partially blocked orifice.
- delayed ignition or repeated clicking: verify electrode⣠position and grounding; check for gas⣠accumulation risks before retrying.
- Gas leak at threads: âreplace gaskets and âperform a soap-solution leak test at operating pressure.

Q&A
What is âthe 316536610 Frigidaire Ignitor/Orifice Assembly?
The â˘316536610 â¤is an OEM Frigidaire⣠ignition/orifice assembly used on certain Frigidaire/Electrolux gas ranges â˘and⣠ovens. it combines the âhot-surface or spark ignitor function with the burner âorifice that meters gas flow toâ the â¤burner.⣠It is indeed a replaceable component that restores proper ignition and gas delivery when the âoriginalâ assembly has âfailed or become clogged/damaged.
How do I noâ whetherâ this âis the correct partâ for my appliance?
Check your appliance model number (located on the range/oven âframe, behind the broiler â˘draweror â˘on â˘the door jamb)â and cross-reference it⤠with frigidaire’s parts list or an authorized parts dealer. Many parts sellers will let you enter the model number to confirmâ compatibility. Do not rely â¤on appearance alone-model-specific cross-reference is âthe reliable method.
What symptoms indicate the ignitor/orificeâ assembly is bad?
Common symptoms include the burner or oven not igniting, delayed ignition (a long glow before the⢠burner lights), weak⣠or uneven flame, repeated⢠clicking withoutâ ignition, â˘or aâ persistent gas odor when attempting to light the appliance. Note that a glow-type ignitor can still visibly⢠glow yet fail â¤to draw sufficientâ current to âopen the gas valve,â so visible glow alone does not guarantee correct function.
Can I â¤test⤠the ignitor myself to see if it’s faulty?
You can do⤠basic checks: visually inspectâ for cracks, breakageor âŁheavy deposits; ensure â˘connectors are â¤secure; and check for electrical âcontinuity with a multimeter. âŁhowever, precise diagnostics (checking current draw and â¤gas-valve âoperation) are best â˘performedâ by a trained technician. If⤠you measure an open circuit (infinite⣠resistance) the âignitor is⤠likely failed.If you’re unsure or unfamiliar with electrical testing, have â¤a qualified appliance technician evaluate the part.
