Teh 316536610 Frigidaire Ignitor/Orifice Assembly is a combined ignition and gas metering component used in Frigidaire gas appliances; it integrates an ignitor element with a precision orifice or nozzle to initiate and regulate combustion at a burner. As a hardware assembly it typically includes the ignition element (hot surface or spark type,depending on the model),the orifice that controls gas flow to the burner,mounting hardware and electrical terminals for connection to the appliance control system.
Within the appliance the ignitor/orifice assembly serves two primary functions: providing the energy source to ignite the gas and establishing the correct fuel flow for stable combustion. It interfaces directly with the gas valve and burner tube, and indirectly with the appliance control board, safety interlocks and flame-sensing devices; correct timing, electrical resistance and orifice sizing are all critical to coordinated operation. because it affects both ignition reliability and flame characteristics, the assembly is integral to safe startup, combustion efficiency and proper heat output in gas ovens, ranges and similar appliances.
This article will explain how the 316536610 assembly functions, identify the appliance models and configurations in which it is used, and outline common compatibility considerations. It will describe typical failure symptoms-such as no ignition, delayed ignition, weak or uneven flame, or gas odor-and provide a systematic approach to basic troubleshooting and testing (visual inspection, electrical checks, orifice verification and interaction with control signals). the article will discuss replacement considerations,safety precautions,and factors to review when selecting a replacement part,including mounting,connector type and adherence to local gas and electrical codes.

function and Role of the Ignitor/Orifice in Burner Ignition and Gas Metering
The 316536610 Frigidaire Ignitor/Orifice Assembly integrates two precise functions: gas metering and ignition. The orifice is a precision-machined constriction that establishes the volumetric flow and pressure drop required for the burner’s rated heat output; its diameter and seat geometry determine the mass flow for a given inlet pressure and therefore the flame size and combustion characteristics. The ignitor element (spark electrode or hot surface, depending on application) delivers the energy necessary to initiate combustion at the burner port.Together in a single assembly thay maintain alignment between the ignition source and the metered gas stream, reducing ignition delay and ensuring consistent light-off across operating conditions.
- Function: metering gas flow and delivering ignition energy at a controlled location.
- Common symptoms of malfunction: delayed or repeated ignition, weak/yellow flame, soot buildup, or persistent clicking after valve closure.
- Compatibility considerations: correct orifice size for natural vs. LP gas, matching electrical connector and mounting geometry, and correct pressure/regulator settings.
- Service cues: inspect for debris or corrosion in the orifice, verify electrode gap and insulation, and confirm proper valve timing and spark presence with diagnostic tools.
In practice, technicians must match the 316536610 assembly to the appliance’s gas type and mechanical interface rather than substituting by appearance alone. For example, converting a range from natural gas to LP requires a smaller orifice and may also require verifying regulator settings; installing an assembly with the wrong orifice will produce unstable combustion or excessive gas flow. When diagnosing intermittent ignition, measure spark presence and timing, visually inspect the orifice for blockage, and confirm that the ignitor’s insulation and wiring are intact. Replacements that meet the original orifice specification, electrical ratings, and mounting dimensions restore designed burner behavior without altering calibrated gas metering or safety responses.

|---|---|
| Orifice | Precision restriction that sets gas flow rate; sized for natural or LP service and specified diameter/number. |
| Ignitor | Spark electrode or hot surface element that provides ignition energy; requires proper mounting and electrical connection. |
| Compatibility | Must match appliance mounting, gas type, and electrical interface; use assemblies specified for the appliance model or equivalent specifications. |
How the 316536610 Frigidaire Ignitor/Orifice Assembly Works Inside the Appliance: electrical Operation, Thermal Response, and Gas flow Dynamics
The 316536610 Frigidaire Ignitor/Orifice Assembly combines a hot‑surface ignitor with a precisely machined gas orifice to control ignition timing and initial fuel flow in Frigidaire gas ovens and ranges. Electrically, the control board supplies line voltage to the ignitor; the device is designed to heat rapidly to a red‑hot temperature that provides the energy required to ignite the gas.The ignitor’s electrical characteristics – resistance and steady‑state current draw – directly affect valve behavior: the system sequences gas valve opening only after the ignitor reaches a threshold thermal output or after the control senses the expected current profile. This interplay of voltage, resistance, and heat generation is why a weak or high‑resistance ignitor delays ignition even when the valve and wiring appear functional.
- Common operational symptoms: failure to light, long ignition delay, or yellow/sooty flame indicating incomplete combustion.
- Service checks: measure cold resistance and operating current,inspect orifice seating and alignment,and verify correct model compatibility.
- Design considerations: orifice size and geometry set the volumetric flow rate and jet shape that must match burner ports and manifold pressure for clean combustion.
Thermally, the ignitor must reach and maintain a specific surface temperature to ignite the fuel-air mixture instantly when gas is metered through the orifice; rapid thermal response minimizes the open‑gas interval and reduces the chance of delayed ignition and flashback. The orifice establishes local gas velocity and pressure drop,creating a short,concentrated jet aimed at the hot surface; mismatched orifice size or manifold pressure changes will alter the equivalence ratio at the ignitor face and can produce unstable flames or poor heat transfer. For practical field work, technicians should replace the assembly with one that matches the original electrical resistance, orifice specification, and mounting geometry – swapping only the ignitor or only the orifice can leave the system out of spec and cause persistent ignition or combustion issues.

Common Failure Symptoms and Measured Diagnostic Indicators for Ignitor/Orifice Malfunctions
The 316536610 Frigidaire Ignitor/Orifice Assembly combines the ignition element and calibrated gas jet into one serviceable unit; the ignitor provides the heat or spark to initiate combustion while the orifice controls gas flow to produce the correct flame shape and heat output for a specific Frigidaire range or cooktop. Functionally, a healthy assembly produces a swift, repeatable ignition and a stable, blue flame. Compatibility depends on matching the assemblyS mounting, orifice sizing and ignitor type to the appliance’s manifold pressure and valve characteristics-installing an assembly with an incorrect orifice size or an ignitor with the wrong electrical requirements will cause poor combustion, delayed ignition, or safety interlock faults.Always disconnect power and gas before performing electrical or flow measurements.
- No ignition or long ignition delay – ignitor shows open circuit or abnormally high resistance, or the orifice is restricted.
- Weak, lifting, yellow, or sooty flame - indicates reduced flow through the orifice or incorrect air/gas ratio.
- Intermittent ignition or pilot dropout – can point to marginal ignitor heating/current or loose wiring/connectors.
- Full voltage present at the ignitor connector when calling for heat but no glow or spark - ignitor element likely failed.
- Gas odor without ignition – manifold valve may be opening but the ignitor/orifice pair is not producing a stable flame; treat as a safety condition.
| Item | Description |
|---|---|
| Continuity | Ignitor should show continuity (closed circuit); open circuit indicates a failed element. |
| Resistance | Typical glow ignitor resistance is in the low tens to low hundreds of ohms; notable increases indicate ageing or impending failure (consult service sheet for exact values). |
| Supply Voltage | Measure line voltage at the ignitor connector during a call for heat; presence of expected supply voltage with no glow indicates ignitor fault. |
| Flame Pattern | Healthy orifice yields a stable blue cone; yellow tips, lifting, or sooting indicate flow restriction, incorrect orifice, or air/gas imbalance. |
Technicians should use a multimeter to verify continuity and resistance of the ignitor, and a voltmeter to confirm supply voltage under load; a wiring harness swap with a known-good burner or a bench test of the ignitor can quickly separate electrical failures from flow or orifice issues. For practical troubleshooting, pair electrical checks with a visual flame assessment and, if available, a static pressure measurement at the manifold-an otherwise healthy ignitor with low manifold pressure or a partially blocked orifice will still produce weak or unstable flame, whereas a correct pressure with an open/failed ignitor requires replacement of the 316536610 Frigidaire Ignitor/Orifice Assembly or the ignitor element per the appliance service manual.
Replacement Considerations and Installation Procedures: Model Compatibility, Torque Specifications, and Safety Checks
The 316536610 Frigidaire Ignitor/Orifice Assembly combines the ignition electrode and the gas orifice into a single serviceable unit that controls initial gas delivery and provides the spark or hot-surface element necessary to light the burner. Functionally, the orifice meters a fixed volumetric flow while the ignitor provides a reliable ignition source; wear on the electrode, carbon buildup, or a damaged orifice seat will change ignition timing and flame geometry, producing delayed ignition, yellow tipping, or weak flames. Verify compatibility by cross-referencing the model number stamped on the range or the manufacturer parts list-differences in valve thread, orifice size, and mounting flange orientation among Frigidaire ranges can prevent proper sealing or alignment even when the assembly appears to fit physically.
Follow a controlled replacement procedure: disconnect electrical power and shut off the gas supply, then remove the old assembly, inspect the valve threads and mating surface for burrs or gasket remnants, and install the new assembly with correct alignment of the ignitor relative to the burner port. Use a calibrated torque driver and apply the recommended hand-torque ranges: mounting screws to chassis or bracket should be torqued to approximately 20-30 in‑lb, the orifice-to-valve seating to approximately 30-60 in‑lb, and small sensor or electrode-set screws to about 8-12 in‑lb; these are typical values-refer to the specific service manual for an exact figure. After installation perform a gas-leak check with a detector or soapy solution, observe flame shape and stability across low and high settings, and confirm reliable ignition over multiple cycles before returning the appliance to service.
- Key steps: isolate gas/electric, remove old assembly, clean mating surfaces, install and torque to spec, leak test, verify flame and ignition timing.

Q&A
What is the 316536610 Frigidaire Ignitor/Orifice Assembly and what does it do?
The 316536610 assembly is an OEM replacement part for Frigidaire gas ovens/ranges that combines the ignition element (ignitor) and the gas orifice/nozzle used to meter gas to the burner. The ignitor heats or produces a spark to ignite the gas delivered through the orifice. The assembly ensures correct alignment, safe gas flow and consistent ignition of the oven or broiler burner.
How can I tell if the ignitor/orifice assembly is failing?
Common symptoms include: the oven/broiler fails to ignite, the burner takes a long time to light, the ignitor does not glow when the oven is set to heat, visible cracks or damage to the ignitor element, or irregular flame (weak or yellow). If the ignitor glows but gas does not ignite,the orifice could be clogged or the gas valve could be faulty. Always verify other components (gas valve, safety thermostat, control board) before assuming a single cause.
How do I test the ignitor to confirm it needs replacement?
Start with a visual inspection for cracks or breakage and a functional test: when calling for heat the ignitor should glow (hot surface type) or the spark should occur (spark ignition type). With power off, you can check continuity with a multimeter to see if the element is open-circuit (no continuity = bad). Measuring actual current draw while powered is a more definitive test for hot surface ignitors but should only be done by a trained technician because it exposes you to live circuits and gas.
Is this part compatible with my frigidaire appliance?
Compatibility depends on your specific model number. Check the appliance model plate (usually inside the oven door frame, on the frame behind the broiler drawer, or on the back) and compare against Frigidaire parts diagrams or the retailer’s compatibility list.If in doubt, provide the full model number to the parts supplier or consult an authorized technician to confirm fit and gas type (natural gas vs. LP/orifice differences).
Can I replace the 316536610 myself, and what are the basic steps?
Many competent DIYers can replace this assembly, but you must follow safety procedures: shut off gas supply and disconnect electrical power before starting. Typical steps: remove the oven access panel, disconnect wiring and the ignitor mounting screws, remove and replace the old assembly, reconnect wiring and tighten gas fittings, restore gas and power, then perform a leak test and functional test. If you are not pleasant turning off/handling gas or live electricity, hire a qualified technician.
What safety checks should I perform after installing the new assembly?
After installation, restore gas and perform a leak check at all new fittings using a soapy-water solution (look for bubbles) or an approved commercial leak detector. Restore electrical power and observe a full ignition cycle: the ignitor should operate and the burner flame should establish promptly and burn blue and steady. If you smell gas, shut off supply immediately and ventilate the area. If ignition is slow, intermittent, or flame is yellow, turn off the appliance and call a technician.
Should I replace only the ignitor or the whole ignitor/orifice assembly?
Replacing the entire ignitor/orifice assembly is ofen recommended because the orifice can be specific to natural gas or LP and can become clogged or worn. The complete assembly ensures proper alignment,correct orifice sizing,and new seals/fittings-reducing the chance of leaks or installation issues. If the ignitor alone is available and the orifice is known to be in good condition and the correct type, a single-part replacement can be acceptable.
How long does this part typically last and is there a warranty?
Service life varies with usage and conditions; many ignitors last several years (frequently enough 5-10 years) but heavy use, moisture, or knocks can shorten lifespan. Warranty terms depend on where you purchase the part-OEM retailers or Frigidaire-authorized dealers often offer a limited parts warranty (commonly 90 days to 1 year). Keep purchase records and check the seller’s warranty policy before buying.
