Functional Role: Ignition, Flame âŁRegulationand Safety Responsibilities of the Ignitor/Orifice Assembly
The 316536602 Frigidaire Oven ignitor/Orifice Assembly combines a hot surface ignitor âwith a precision gas orificeâ to âinitiate âcombustion and control⣠flame characteristics in compatible Frigidaire ovens. The ignitor must âreach a specified temperature and draw âsufficient current to allow the safety gas valve to open; the orifice meters⢠the volume and velocity of gas delivered to the burner so âthe flame is stable and properly positioned. Replacement or servicing requires matching the orifice size to the appliance’s fuel type (natural gas or LP) and confirming connector, mounting, âand electrical specifications to ensure the⣠valve circuit and flame dynamics remain âwithin âŁthe oven’s design parameters.
The assembly’s responsibilities⤠span ignition initiation, flame regulationand safety âŁinterlock behavior: it prevents uncontrolled gas flow until the ignitor establishes reliable ignition conditions, âshapes the burner jetâ to produce the correct â˘flame envelopeand⣠interacts with the oven’s control logic to â¤stop fuel delivery â˘if⢠ignition fails. Practical diagnostic checks include âŁverifying that the ignitor reaches âŁoperating glow withinâ the service time, measuring â˘cold resistance⢠againstâ the service manual, inspecting flame color and steadiness after ignition,â and confirming orifice âsizing after any fuel conversion; typicalâ fieldâ symptoms of a failing unitâ are sustained⣠ignition delay, no flame âŁdespite a glowing ignitoror an unstable/yellow flame indicating incorrect âgas metering.
- Observe âŁignitor glow time and visual â¤flame behavior.
- Measure cold resistance and compare to service specification.
- Confirm orifice size matches fuel type and âŁconversion kit.
- Check electrical connector and mounting integrity before replacement.

How the 316536602 Frigidaire Oven Ignitor/orifice â¤Assembly Operates Within the Gas delivery and Control System
The 316536602 Frigidaire Oven Ignitor/Orifice Assembly combines a hot-surface ignitor and a precision⣠gas orifice to initiate and⢠regulate⤠combustion⢠at âŁthe bake â˘burner. In ânormalâ operation the oven control applies voltage to the âignitor; âas the ignitor âŁheats it changes electrical characteristics â˘(typically a fall âinâ resistance or an increase in current draw as it reaches operating temperature),and the control or gas valve⣠senses that condition before energizing â¤the âŁvalve. Once the âvalve âŁopens, the orifice providesâ a fixed pressureâ dropâ to âŁmeter gas flowâ to the burnerâ head,â producing a stable flame size appropriate âtoâ the oven’s âdesign. this â¤assembly is a mechanical â˘and electrical⢠interface: the ignitor providesâ the âŁrequired pre-ignition signal and the orifice provides the âcalibrated fuel delivery that together determine âsafe, repeatable ignition and heat output.
- Ignition sequence: âŁcontrol⤠energizes ignitor â¤â â˘ignitor reaches operating âtemperature â⤠gas valveâ is allowed â¤to open â âŁgas flows through orifice â flameâ established and monitored.
- Safety behavior:â the control uses the ignitor’s electrical behavior âto prevent valve operation until ignition conditions areâ met.
- Compatibility considerations: orifice sizing and valve solenoid ratings must match âthe oven’s gas type (natural vs. LP) and model specifications.
- Common symptoms of mismatch or failure:â delayed â¤ignition, weak or lifting flameor valve cycling.
Integration⣠into â¤the gas delivery and controlâ system requires that the 316536602 assembly match both the physical mounting and the functional specifications of the âoven model – the correct orifice hole size for the fuel type â˘and⤠a compatible ignitor electrical signature for the â˘control⣠and valve. Technicians should verify⤠mechanical fit, wiring polarity and connector typeand â¤confirm the âassembly’s performance with bench tests: observe â¤the ignitor heating⤠time and current draw, check for stable valve operation when âthe control callsâ for heat, âand âconfirm flame characteristics âafter installation. replacing only the â¤ignitor or only the â¤orifice without â˘ensuring matched specifications âŁcan lead to prolonged ignition times, improper combustionor safety interlock failures, so use the assembly designated for the model or equivalent parts with documented compatibility.

Common Failure Modes and diagnostic Symptoms: Electrical, Thermaland Gas-Flow Indicators
The 316536602 Frigidaire Oven Ignitor/Orifice Assembly combines the ignition element and gas metering orifice into a single serviceable unit. âIts electrical behavior is governed by the ignitor âŁelement:â as the element⤠heats itâ must⤠draw sufficient current to actuate the oven⢠safety gas valve. Common electrical failures âincludeâ open circuits, â˘increased element resistance that reduces current drawor intermittent connections at the wiring harness or mounting terminals. thermally driven failures âshow as gradual degradation of glow âintensity or brittle âfracture of⤠the ceramic/elementâ from repeated⣠thermal cycling; those symptoms frequently enough coexist with or accelerate electricalâ faults. The orifice portion controls jet size and combustionâ characteristics, âso âŁphysical blockage,â corrosion,⢠or use of the wrong â¤orifice for⢠the fuelâ type (natural gas vs. LP)⣠willâ change flame shape, cause delayed ignitionor produce sootingâ despite a functional â¤ignitor.
Diagnosing faults requires combining visual, electricaland gas-flow â¤checks: visually⢠inspect the âignitor for cracks, discolorationor broken leads; measure continuity and compare resistance and inrush current⢠to the oven’s service âspecification; and verify gas⤠pressure âand orifice⢠cleanliness with⤠a manometer and a careful inspection âŁof the jet. Practical examples: a bright glowing ignitor that neverâ opens the valve usually indicates a âvalve/electrical control⣠orâ wiring fault, whereas a dim or⤠slow-warming ignitor that prevents the valve from opening âpoints toâ a â˘weakened element. Delayed ignition with âyellow, âsooty flame typically implicates a clogged âor incorrectly sized⣠orifice⢠or âlow gas pressure; persistent delayed ignition combined with an intermittently glowing or cold ignitor suggests the⣠assembly should be replaced. Replace theâ integrated âŁassembly when electrical and gas-flow faults coincideand always â˘confirm the replacement orifice matches the appliance’s fuel type and regulator settings.
- No âignition â˘but ignitor glows (electrical continuity with insufficient current draw)
- Delayed ignition with âpopping or sooting⤠(clogged/incorrect orifice or low pressure)
- Long preheat times or oven temperature overshoot (weak ignitor or thermal degradation)
- Intermittent operation or â˘visible cracking of the ignitorâ element
- Gas odor â˘before ignitionâ (delayed ignition-shut offâ appliance and ventilate â˘immediatly)
| Item | Description |
|---|---|
| High-resistance or open⤠ignitor | Element degradation or broken lead; multimeter shows high resistance or no continuity and âŁthe element fails to drawâ valve-opening current. |
| Clogged/incorrect orifice | Restricted jetâ or wrongâ orifice size alters flame shape, causes delayed ignition, sooting,⢠or incomplete combustion; âinspect and match⣠to fuel type. |
| Thermal cycling damage | Repeated heating cool-down cycles cause ceramic orâ filament fatigue, reduced glow intensityand intermittent failures noticeable â¤under load. |
Compatibility, Replacement Considerationsand Installation Best practices for Frigidaire Oven Models
The â316536602 Frigidaire Oven Ignitor/Orificeâ Assembly combines the hot-surface ignitor and the fixed âgas orifice thatâ together control ignition and initial gas flow to the bake burner. The â˘ignitor’s electricalâ behavior (glow â¤current and warm-up time) determines⢠the gas valve’s response while the orificeâ diameter⣠and âthread/mounting âgeometry determine metered flowâ and flame characteristics; mismatchingâ either element can cause delayed ignition, weak flameor continuous valve opening. Technicians should verify the⤠oven model âŁtag and partâ cross-reference before ordering, confirm the harness connector styleâ and mounting flange dimensions against the replacementand ensure the orifice matches the appliance’s gas type (Natural âvs. LP) because swapping â¤an orifice drilled for a different gas â˘will change burner pressure âand combustion behavior even if the âŁignitor fits â˘physically.
Follow âŁestablished service procedures for replacement: de-energizeâ electrical power and shut off the gas âsupply, remove â˘and visually inspect the ignitor for cracks or excessive erosionand verify ignitor resistance and warm-up âcurrent with a multimeter as a bench test prior to installation. During installation, align the mounting face andâ gasket âto maintain correct burner â˘alignment, use the correct torque on âŁfasteners to avoid cracking the ceramic ignitor baseand perform a âleak and combustion check after restoration of gas and power; also document the original part number and oven model for future reference. Practicalâ pre-install checks include:
- Confirm âOEM â¤part number and compare⢠mounting hole pattern and connectorâ type.
- Verify replacement orifice is specified for the same gas⢠type âŁand pressure.
- Measure ignitor cold resistanceâ andâ observeâ glow timing during a âbench â¤test.
- Perform a post-installation⤠leakâ test and â˘monitorâ burnerâ flame stability.

Q&A
What is âthe âfunction of the 316536602 Frigidaire oven ignitor/orificeâ assembly?
The assembly contains theâ oven⤠ignitor (a hot-surface or spark element depending on âdesign) and the gas orifice/mounting hardware. Together⤠they allow gas to flow to the â¤oven burner and ignite it safely. âThe ignitor heats or sparks to⢠light⤠the gas coming through the orifice; the orifice meters the gas flow so the â¤burner âŁgets the correct fuel volume.
Whatâ are common symptoms that this âŁignitor/orifice assembly is failing?
Typical â¤signs include: âthe⢠oven won’t light or takes âa very long time to⢠heat,oven â˘won’t maintain âtemperature,the ignitor fails to glow,burner âflames are weak or yellow,or the oven lights briefly then goes out. Visible damage⣠(cracks, breaks) or heavy corrosion around the orifice are also indicators.
Does the 316536602 part include both the âignitor and the orificeor are they sold separately?
A part describedâ as an “ignitor/orifice assembly” is usually supplied with both the ignitor and the orifice plus the mounting âbracket and necessary hardware.Though, suppliers sometimes sell components separately, so always check the exact product description âŁor part âpicture and confirm compatibility for âŁyour model before ordering.
Howâ can I test the ignitor âŁto see âif it needs replacement?
Start with a visual check:⢠when the oven calls â˘for heat the ignitor should glow (if it is a hot-surface type).⣠For electrical checks, first disconnect⣠power. Use a multimeter⣠to â¤check for continuity-no continuity indicates a failed element. Note that continuity⣠alone does notâ prove the âignitor will draw âsufficient current to open the gas safety valve; a full⢠diagnostic measures the â¤current draw âduring ignition per the service⤠manual. Ifâ the ignitor glows but â¤the⢠oven won’t light or the ignitor is dim, it⢠is often weak and should be replaced.
Can â¤I âŁreplace the 316536602 assemblyâ myselfand what safety â˘steps should â˘I take?
Many competent DIYers can replace the assembly because âit is usually accessible from inside theâ oven cavity. Important⢠safety âsteps: turn off and disconnect electrical power,⢠shut off the⤠gas supplyand work inâ a⤠well-ventilated area. Remove the oven bottom/inner panels â¤to access the⢠burner, disconnect wiring, âunbolt the⤠old âŁassembly and install the new oneâ in the⣠same orientation. After reassembly and restoring gas and power, perform⢠an audible/soapy-water leak âcheck at the âgas connection and test for correct ignition. If you âŁare not comfortable with gas or electrical⣠work,⤠hire a qualified appliance⣠technician.
Why âdoes⢠the oven light for a second and then shutâ off after I install a newâ ignitor/orifice assembly?
If the oven lights âbriefly then goes out it usually indicates the ignitor is not drawing enough currentâ to keep the gas safety valve openor the valve itself orâ the control circuit is âfaulty. A weak/new-but-defective âignitor,⣠wrong âorifice size,â a partially clogged âŁorifice,⤠orâ a⢠defective gas âsafety valve⤠can produce this symptom. proper testing includes â˘measuringâ ignitor current draw during ignition and inspecting the orifice and valve for blockage or damage.
How do I verify that this part is compatible with my Frigidaire⢠oven model?
Locate your â¤oven’s model number (usually â¤on a â˘tag inside the oven door frame or on the appliance’s back) and cross-reference it with the replacement part number using Frigidaire’s parts diagram,the⢠parts retailer’s compatibility lookup,or the manufacturer’s parts âlist. do not assume visual âsimilarity equals compatibility-mounting holes, â¤orifice size and electrical connectors â˘must match the original.
How⤠long does an âoven â˘ignitor/orifice assembly typically lastand what â¤commonly causes⢠failure?
Service life varies with use but ignitors commonly âlast several years (often 5-10 â¤years or more under⣠normal â¤use). Common⣠failure â˘causes include thermal âŁcycling fatigue, physical damage, moisture/corrosion at connectionsor contamination/clogging of theâ orifice. Repeated hard starts or voltage irregularitiesâ can also⣠shorten ignitor âlife.
