316536602 âFrigidaire â¤Oven Ignitor/Orifice Assembly is a combined ignition and gas metering component used in Frigidaire gas ovens and ranges. The assembly typically incorporates a hotâsurface ignitor⣠(glow element) and a fixed orifice or jet mounted together⣠with the necessary bracketry and electrical connector, providing both the heat source for ignition and the controlled gas outlet for the burner.
Within the appliance the assembly interfaces directly with the oven burner, â¤the gas safety/valve assembly and the oven control circuitry. when the control⤠calls for heat it supplies â¤voltage to the ignitor so⢠the glow element âreaches ignition temperature; at the appropriate temperature the gas valve âopens âand gasâ flows through the orifice where it is ignited. The component therefore affects ignition reliability, flame stability, warmâup time and interaction with safety interlocks and flame sensing âcircuits.
In this article readers will find a technical overview of how the 316536602 assembly âfunctions, which Frigidaire models and burner locations commonly use it, âtypical failure symptoms (forâ example no ignition, extended preheat, weak or unstable flameor gas odor), diagnostic checks (visual inspection, resistance and voltage measurementsand⣠mounting/alignment verification) and practical replacement âconsiderations (matching part numbers and connectors, mechanical fit, â¤and postâreplacement testing). Safety precautions for working on gas and electrical systems⣠will be âŁhighlighted â˘as part âof the troubleshooting and servicing guidance.

Function and Role of the Ignitor/Orifice Assembly âin Frigidaire Gas oven Ignition Systems
The 316536602 Frigidaire Oven âIgnitor/Orifice Assembly combinesâ a hot-surface âignitor element with a matchedâ gas orifice into âŁa single serviceable unit that establishes both the ignition⢠energy and the metered gas flow for the oven â¤burner. âThe ignitor provides the localized heat necessary to initiate âcombustion, âwhile the orifice restricts and shapes the gas passage âso the flame size and heating rate meet the appliance’s design. As â˘the two components are factory-matched,⣠the assembly preserves the intended⤠ignition timing and combustion characteristics when installed âŁin compatible Frigidaire ranges.
Operational behavior toâ monitor includes the ignitor’s warm-up glow, â¤the speed and⤠consistency⣠of flame âŁestablishmentand⢠the flame appearance instantly after ignition; common failure modes are slow ignition, intermittentâ flame, low heat outputor gas odors from delayed ignition. technicians should verifyâ model and â¤fuel-type compatibility before replacing âthe part, confirm proper seating and gasket condition to prevent leaksand â¤test the ignitor and gas valve circuit per manufacturer â¤procedures rather than relying on visual â¤inspection alone. Such⢠as, replacing a failed ignitor without the matched orifice can alter âflame shape and cooking performance, whereas installing the complete 316536602 â˘assembly maintains the intended gas/air balance and minimizes further â˘adjustment.
- Primary functions: ignition⣠energy (ignitor) andâ gas metering (orifice).
- Typical symptoms of assembly failure: slow ignition, weak flameor no sustained combustion.
- Compatibility notes: confirm oven model andâ fuel type; maintain correct âmounting and sealing.

How the 316536602 frigidaire Oven Ignitor/Orifice Assembly Works Inside the Appliance
Theâ 316536602 Frigidaire Oven Ignitor/Orifice Assembly integrates a hot-surface ignitor element and a matchedâ gas orifice into âa â˘single service item used on compatible Frigidaire ranges. The hot-surfaceâ ignitor is a resistive ceramic element that â¤heats and glows⣠to provide the thermal â¤energy and current draw required to actuate the oven gas valve; the orifice âis a precision metering port that shapes the gas âŁflow to the burner head and sets the flame size and pressure for the oven’s rated BTU. Because the twoâ components are matched inâ the assembly, correct function depends on both the electrical characteristics of the ignitor and the physical size and threading of the orifice; replacementâ should match the oven model’s specified part number and gas type (natural gas vs. LP) to ensure proper combustion and safety interlock behavior.
Technically, failures present in predictable ways that help distinguish â˘ignitor problems from orifice or â¤valve issues. A weak or failing ignitor⢠may glow but not draw sufficient current to open the gas valve, producing long ignitionâ delays or no flame, while a clogged or incorrectly sized orifice typically yields a small, sootyor yellow flame and poor heat output. Practical troubleshooting steps include a visualâ check for glow, a continuity or cold-resistance check of the ignitor,⢠and a live-current clamp measurement during the oven’s call for âŁheat to verify âthe ignitor draws âŁthe âexpected operating current; inspect the orifice for⢠debris and confirm the part threads and â˘sealing surfaces match the appliance. Common âsymptoms and checks include:
- ignitor does not glow⤠– continuity/open-circuit test and replacement of ignitor âŁelement.
- Ignitor glows but no gas flows – measure current draw to check for weak ignitor; check gas valve function.
- Small, yellowor sooty flame – clean or replaceâ orifice and confirm correct orifice size for LPG vs. ânatural gas.
| Item | Description |
|---|---|
| Ignitor | Provides heat and electrical load to initiate gas valve opening; electrical characteristics âdetermine compatibility with âthe oven control âcircuit. |
| Orifice | Precision â˘gas metering port that determines flame size and combustion characteristics; âŁmust match gas type and burner design. |
common Failure Symptoms⤠and Measurable Indicators of Ignitor/Orifice Assembly Faults
The 316536602 Frigidaire Oven Ignitor/Orifice Assembly combines the hot-surface ignitor element and the matched gas orifice into a single functional unit that controls ignition timing and flame characteristics. In normalâ operation the ignitor âmust â˘heat toâ a visible orange glow and draw sufficient current â˘to actuate the gas valve; the orifice size⤠then meters the gas flow to produce a stable burner flame. Failures of⣠this assembly can be electrical (open or high-resistance ignitor), thermal (slow or dim glow)or mechanical/match issues with the orifice â¤(incorrect flow for natural⤠gas vs. LP or partial blockage),â all of which change measurable⤠parameters during service tests.
- No â˘ignition or repeated shutdowns⢠despite glowing element – suggests insufficient current draw or âŁweak ignitor.
- Long glow time before â˘ignition (greater than typical range) – indicates degraded element resistance or incorrect orifice sizing.
- Visible â¤dim or uneven glow – points to partial filament damage or internal cracking increasing resistance.
- Strong gas smell or flame blowout â¤when⤠ignition finally⣠occurs â- can indicateâ a mismatched orifice or delayed valve timing.
- Multimeter shows â˘open circuit or âŁresistance well outside expected range – confirms electrical failure of the ignitor.
| Item | Description |
|---|---|
| Cold resistance (DC) | Typical hot-surface ignitors measure on the order of tens to a⤠few hundred ohms; an open (infinite) reading indicates a failed element. |
| Current draw (energized) | When powered, aâ healthy⣠ignitor should draw amp-level current sufficient to pull the gas valve; considerablyâ lower current correlates with weak heating and ignition âfailure. |
| Ignition glow time | Proper assemblies reach âbright orange âwithinâ seconds; substantially longerâ glow times or âdelayed â¤valve actuation indicate degraded performance or flow mismatch. |
Technicians confirm faults by combining visual observation⤠with instrument measurements: measure DC â¤resistance âwith the oven cold, check for continuity, observeâ glow⣠intensity â¤and timing under actual supply voltageand if possible measure currentâ drawâ or valve actuation timing. For âreplacement or compatibility decisions, verify that the 316536602 Frigidaire Oven Ignitor/Orifice Assembly⢠matches the oven model and the fuel type (natural gas vs. LP); using an orifice sized for the wrong fuel â˘or a partially obstructed âorifice will produce the same symptoms as a weakened ignitor and can mask the true root cause. Before performing live tests that involve gas⢠or mains voltage, isolate power and gas and follow approved safety procedures.
Replacement Considerations, Mounting and â˘Installation Procedures for the Ignitor/Orifice â¤Assembly
The 316536602 Frigidaire oven Ignitor/orifice Assembly combines the replaceable hot-surface âŁor spark ignitor with the gas â¤orifice to control ignition timing and gas flow for a Frigidaire oven. The ignitor must âdevelop sufficient heat and draw the required current to allow the gas valve to open, while the orifice diameter sets the gas flow rate and affects flame shape and combustion stability. Compatibility âis determinedâ by oven model and fuel type (natural gas vs. LP); mismatched orifice sizing, mounting geometryor electrical connectorâ style can cause weak ignition, delayed burner onsetor improper combustion. Troubleshooting typically includes a visual â¤inspection for cracking or âcarbon buildup, a continuity/resistance check of the ignitor,⣠and inspection âof the orifice port for obstruction â¤before replacement.
mounting and âinstallation require careful alignment and secure electrical and gas connections to restore reliable âoperation. Before âdisassembly, shut off both power and gas, label â¤any wiringand observe⤠the original orientation so the âignitor tip âand orificeâ align with the burner ports; incorrect spacing or misalignment alters flame impingement and can lead to⤠incomplete âcombustion. âAfter installing⤠the assembly,⢠tighten âfasteners to avoid distortion âof the bracket, perform a leak test at the gas connectionand verify ignition timing and flame pattern during â˘a functional run; if converting fuel type or replacing with a nonâOEM part, confirm orifice size and â¤valve compatibility with the oven’s service documentation.
- Shut off power âand gas, then accessâ the burnerâ compartment.
- Verify part ânumber and fuel type before removal.
- Replace assembly maintaining original orientation and connector types.
- Secure mounting hardware without overâtorquing; perform a gas leak check.
- Validate âignition time and â¤steady flame â¤patternâ after installation.

Q&A
What is the 316536602 Frigidaire Oven Ignitor/Orifice Assembly?
The 316536602 is â¤an âOEM replacement glow-type ignitor with its matching gas orifice for certain Frigidaire (and some kenmore) gas⣠ovens/ranges. The ignitor is the hot-surface element that heats and draws enough current to actuate the gas valve, while the orifice (orâ injector) meters the â¤correct gas flow to the burner. Together they allow safe, timed ignition âŁof the bake or broil burner.
What symptoms indicate this âignitor/orifice assembly is failing?
Common symptoms âare: oven does not light at all, ignitorâ glows âbut gas ânever flows, oven takes a vrey long âtime to light, weakâ or âdim glowâ from âŁthe ignitoror the oven won’t reach or hold temperature. if the ignitor glows but the gas valve âdoes not open, the ignitor is likely not drawing sufficient âcurrent âto trigger the valve.
How can I test the ignitor to see if it needs â˘replacement?
Safe tests include: (1) Visual: a good ignitor should glow bright orange when calling for heat. (2) â¤Multimeter continuity test: if the ignitor shows open circuit (infinite âresistance) it’s bad. (3) Current draw test: using a clamp ammeter on the ignitor feed, a working oven-type âignitor typically draws a couple of amps (frequently enough around 2-4 A depending⢠on model); â˘a significantlyâ lower current usually means it’s failing.If âunsure, compare to a new part âor â˘consult the appliance service manual.
Does the 316536602 include⢠the orifice for LP or natural âgasand do I need to change anything⤠for conversion?
Some⣠assemblies are⣠supplied with an orifice sized for a specific gas âŁtype (natural or LP). LPâ requires a smaller orifice than natural gas.
