316536610 Frigidaire Ignitor/Orifice Assembly is a combined ignition and gas metering component used on Frigidaire gas-fired cooking appliances. The assembly typically integrates an electrical ignitor element (hot-surface or spark type,depending on the specific appliance model) with a precision-machined gas orifice that controls fuel flow too a burner.As a discrete replaceable part, it is designed to mount at the burner/manifold interface and to present the correct electrical and gas connections for safe, repeatable ignition.
Inside the appliance, the ignitor/orifice assembly interfaces directly with the gas valve/manifold, the appliance control module or gas safety valve, and the burner head. The ignitor provides the necessary energy to initiate combustion while the orifice sets the local gas flow and consequently the flame characteristics; together they affect ignition timing, flame stability, and heat output. The assembly also functions within the appliance’s safety and sensing scheme-any ignition or flow anomaly can trigger lockouts or interaction with flame-sensing circuitry-so correct mounting, orifice sizing, and electrical continuity are important for proper operation.
This article will describe the assembly’s function and typical variants, outline how to verify compatibility with specific Frigidaire models, and list common failure symptoms such as no ignition, delayed ignition, unstable or yellow flame, and gas odors. It will also cover diagnostic checks a technician can perform (visual inspection, electrical resistance/voltage checks, and orifice condition), basic troubleshooting steps, and practical replacement considerations including matching orifice size, proper installation orientation, and safety precautions to observe when working on gas appliances.

Function and Role of the Ignitor/Orifice Assembly in Frigidaire Gas Burner Operation
The 316536610 Frigidaire Ignitor/Orifice Assembly pairs an electrical ignitor with a precision gas orifice to initiate and meter combustion at a single burner. The ignitor produces the energy-either a spark gap or a hot surface depending on the specific appliance design-that reliably lights the fuel as it exits the orifice; the orifice itself is a machined jet sized to produce the correct volumetric flow at the appliance’s manifold pressure. Correct function requires the ignitor to be positioned and referenced to the electrode or burner port for consistent spark or heat, and the orifice to match the appliance’s gas type and pressure rating so flame shape and BTU output remain within design tolerances. Technicians should confirm fitment by matching the OEM part number and verifying connector type,mounting threads,and whether the appliance is set for natural gas or LP service before installation.
- Common symptoms of assembly failure: no ignition or continuous clicking, delayed ignition, weak or yellow/sooty flame, or uneven burner heat.
- Practical checks: inspect and clean the orifice for debris, verify ignitor continuity or glow with a multimeter, confirm electrode gap/alignment, and check manifold pressure and regulator output.
- Compatibility considerations: replacement orifices must match size and gas type; ignitors must match electrical connector and mounting to avoid misfires.
Troubleshooting begins with isolation: shut off gas, remove the burner cap, and inspect the orifice for deposits or physical damage, than measure the ignitor’s electrical characteristics and observe spark location or hot-surface behavior during a controlled ignition test. In practice, a clogged orifice typically produces a low, yellow, or sooty flame while an open-circuit or shorted ignitor will produce no spark or continuous clicking; replacing the affected element within the 316536610 assembly or restoring correct orifice sizing will usually resolve combustion irregularities. When replacing parts, use components rated for the appliance’s manifold pressure and gas type and follow the manufacturer’s torque and sealing instructions to prevent leaks or misalignment.

How the 316536610 Frigidaire Ignitor/Orifice Assembly Works Inside the Appliance Gas Delivery and Ignition Circuit
The 316536610 Frigidaire Ignitor/Orifice Assembly is an integrated burner component that combines a precisely sized orifice with an ignition electrode to control and initiate gas flow to a burner. In normal operation the appliance control opens the gas valve, allowing pressurized gas to reach the orifice; the orifice converts the manifold pressure into a controlled flow rate at the burner port. Concurrently the ignitor electrode produces the ionizing spark (or works as part of a hot surface ignition circuit on some models) to ignite the gas stream. The assembly must match the appliance’s mounting footprint and valve interface so that orifice sizing, alignment, and electrical connections are compatible with the oven or cooktop’s gas delivery and flame-detection circuits.
functionally the assembly is both a flow-metering device and a point of ignition and flame sensing, so its condition directly affects combustion performance and safety. common diagnostic symptoms of a degraded assembly include delayed ignition, repeated sparking without flame, weak or yellow flames, and intermittent flame detection that causes the control to shut off gas. Routine troubleshooting for technicians includes verifying electrical continuity at the ignitor, checking for orifice clogging or carbon buildup, confirming correct mechanical alignment, and ensuring the replacement unit preserves the original orifice size and electrode position. When matching a replacement, use a compatible 316536610 unit or an exact-equivalent part to maintain correct gas delivery characteristics and to avoid changes in heat output or combustion behavior.
- Delayed or absent ignition despite clicking from the spark module
- Weak or yellow flame indicating reduced gas flow or incorrect air mixture
- Continuous sparking with no flame detection (possible electrode fault)
- Gas odour with no ignition – stop use and verify assembly and valve operation

|---|---|
| Orifice | Precision-drilled passage that meters gas flow from the manifold to the burner port. |
| Ignitor electrode | Produces the ignition spark or functions as a hot surface element; may also participate in flame sensing. |
| mounting/interface | Flange, fasteners and gas/ electrical connections that must match the appliance’s manifold and valve assembly. |
Common Failure Symptoms and diagnostic Indicators for Ignitor/Orifice Malfunction
The 316536610 Frigidaire Ignitor/Orifice Assembly combines the hot-surface ignitor and the gas orifice into a matched ignition subsystem that both initiates combustion and meters the gas flow for a compatible Frigidaire range or oven. The ignitor must reach a visible glowing intensity quickly to allow the control valve to sense sufficient current and permit gas flow; the orifice determines the volumetric flow and flame geometry appropriate to the appliance’s design and fuel type. A failing ignitor typically presents as a slow-to-glow or dim element that dose not draw the required current, while an orifice-related problem commonly shows up as an or else-normal ignition event with weak, lifting, or yellow-tipped flames due to a restricted bore or incorrect sizing for natural gas versus LP.
Technicians seperate ignitor and orifice faults by correlating observable behavior with electrical and visual tests: verify that the ignitor attains full brightness and carries expected current during start-up, and inspect the orifice for cleanliness and correct designation for the installed fuel. Control board lockouts or fault codes, persistent clicking without flame, and a persistent gas odor are practical diagnostic indicators that should direct tests toward either the electrical circuit or the gas delivery side. For many repairs the appropriate next steps are to confirm continuity and amperage of the ignitor, check wiring and connectors, and then verify orifice condition and supply pressure; the assembly is replaced when tests show the ignitor fails to reach operating characteristics or the orifice is damaged or wrong for the appliance.
- Delayed or absent glow: indicates weak or failed ignitor or open wiring; confirm by measuring current draw during ignition.
- No ignition with clicking: could be control/valve issue but often tied to insufficient ignitor heat.
- Weak, yellow, or lifting flame: suggests orifice restriction, incorrect orifice size, or pressure problem despite proper ignitor function.
- Intermittent operation: intermittent electrical connection or a marginal ignitor nearing end of service life.
- Gas smell without combustion: safety valve not opening or ignitor not achieving operating temperature-avoid operation until diagnosed.
| Item | Description |
|---|---|
| Ignitor glow | Radiant orange within a few seconds = adequate heating; slow/dim glow = insufficient current or failing element |
| Orifice condition | Clear bore and correct marking for fuel type; debris or wrong size reduces flame and heat output |
| Flame quality | Blue and steady = correct combustion; yellow or lifting indicates orifice or pressure issues |
Compatibility, Replacement Considerations, Installation Procedures, and troubleshooting Methodology
The 316536610 Frigidaire Ignitor/Orifice Assembly combines the ignition element and the gas metering orifice into a single service component that directly controls burner lighting and flame quality. The ignitor provides the initial thermal or spark energy required to open the gas valve or initiate combustion while the orifice determines the delivered volumetric flow for a given manifold pressure; mismatches in orifice size, thread type, or electrical connector will produce weak flames, delayed ignition, or safety valve failures. Technicians should compare the assembly’s mounting pattern, connector type, and stamped orifice size against the appliance model data plate and parts list before installation; many Frigidaire ranges require different orifice jets for natural gas versus LP conversions, so retaining or documenting the original jet is a practical step when replacing the part.
Replacement and troubleshooting follow a sequence of verification, controlled isolation, and functional testing: verify appliance model compatibility and gas type, isolate electrical power and gas supply, remove the old assembly and inspect the burner port for debris or corrosion, and install the new unit with proper torque and alignment. After reassembly, restore power and gas and perform a leak test at the fitting, observe ignition timing and flame shape across low-to-high settings, and use a multimeter to confirm connector voltage and the ignitor’s continuity if ignition problems persist. Common diagnostic symptoms and corrective actions are provided below to assist methodical fault isolation before ordering additional parts.
- pre-install checks: verify model number, gas type (NG/LP), and orifice marking; confirm connector and mounting compatibility.
- Isolation & removal: shut off gas and power, depressurize the line, then remove fasteners and wiring using non-sparking tools as required.
- Functional tests: bench-test continuity of the ignitor, inspect for clogged ports, reinstall and perform leak test, observe ignition timing and flame profile.
- Troubleshooting cues: delayed ignition or sustained clicking suggests ignitor or valve timing issues; yellow or lifting flame suggests wrong orifice or pressure problem; no glow indicates electrical/open-circuit condition.
| Item | Description |
|---|---|
| Compatibility | Match 316536610 to appliance model and gas type; confirm connector, mounting holes, and orifice stamp before ordering. |
| Installation checks | Torque mounting screws to avoid distortion, perform leak test at fittings, and verify correct burner alignment and airflow. |
| Diagnostics | Use continuity checks,voltage verification at the connector,and visual flame inspection; inspect orifice for blockage if flame is weak. |
Q&A
What is the 316536610 Frigidaire Ignitor/Orifice Assembly and where is it used?
The 316536610 is a factory replacement assembly that combines the gas orifice (the metering jet) and the ignition electrode for a Frigidaire gas cooktop or range burner. It is indeed used on select Frigidaire/Frigidaire Gallery/FEG gas models to both direct gas flow into the burner and provide the spark/ignition source for that burner.Always verify compatibility with your exact model number before ordering; parts diagrams or the appliance’s model-specific parts list will confirm fit.
What symptoms indicate the ignitor/orifice assembly is failing and needs replacement?
Common symptoms include: a burner that won’t light or requires multiple attempts, delayed ignition with a loud pop, weak or intermittent spark, visible cracking or corrosion of the electrode, and uneven flame or poor flame shape at that burner. If you smell gas but the burner will not light, stop and follow gas safety steps-don’t continue troubleshooting with an open leak.
How do I test the ignitor portion to determine if it’s bad?
First isolate gas and power to the appliance. Visually inspect the electrode for cracks, heavy carbon tracking, or breaks. For spark-type electrodes you can carefully cycle a burner control (with gas off) and observe whether a spark jumps at the electrode tip; do this from a safe distance and with no exposed gas flow. A multimeter continuity check is sometimes possible but not definitive for spark electrodes (they are part of a high-voltage ignition circuit and may not show simple continuity). If the electrode shows no visible spark or has physical damage,replacement is recommended. if you are unsure, have a qualified technician perform ignition system tests.
Can I install the 316536610 myself and what tools/safety steps are required?
Technically a competent DIYer can replace this assembly, but you must follow strict safety steps: turn off the gas supply to the appliance, unplug the range or switch off the breaker for electrical power, and work in a well-ventilated area. Typical tools: screwdrivers, nut driver or small wrench to remove the burner assembly, needle-nose pliers, and a leak-detection solution (soap/water or commercial detector) for checking connections. After installation, restore gas and power, check for leaks at the threaded connection, and verify proper ignition and flame shape. If you are not pleasant shutting off gas or testing for leaks, hire a licensed technician.
Are there any special installation tips - electrode gap,torque,or sealant to use?
Important tips: position the electrode tip to the same distance from the burner ports as the original (typically around 1/8″ to 3/16″ / ~3-5 mm) to ensure reliable sparking,and avoid bending or stressing the ceramic insulator. Do not over-torque the orifice; tighten snugly to avoid stripping threads but avoid excessive force. Use a gas-rated thread sealant only if the manufacturer specifies it; many orifices are tapered pipe threads that require approved gas-rated thread compound. After installation, perform a leak check on all gas fittings before lighting burners.
Does the 316536610 come in different orifice sizes for natural gas vs. LP (propane)?
Yes – orifice sizing differs between natural gas and LP. Many ranges are shipped set up for one fuel and use the appropriately sized orifice. If you convert fuel types you must use the correct orifice size for that fuel (LP orifice holes are smaller). The correct orifice size and conversion kit facts will be in the appliance manual or on the manufacturer’s conversion instruction sheet. Installing the wrong orifice can cause improper flame and unsafe operation.
Will replacing the ignitor/orifice assembly fix continuous clicking or ignition module issues?
Not always. Continuous clicking can be caused by a faulty electrode, but can also be caused by moisture on the switch or burner, a shorted ignition module, worn wiring, or a faulty gas valve switch. If you replace the ignitor/orifice and the clicking continues, inspect for moisture, clean burner surfaces and switch areas, check wiring integrity, and if necessary test or replace the ignition control module or the spark harness. A systematic diagnosis is required.
How can I confirm I have the correct replacement part or find cross-reference numbers?
Confirm the correct part by using your appliance’s full model number (usually on a tag behind the oven door, drawer, or back panel) and checking the official Frigidaire parts diagram or an authorized parts distributor. Sellers often list cross-reference and OEM numbers, but the safest approach is to confirm against the model-specific parts list. If in doubt, provide the appliance model to the parts supplier or technician to ensure you receive the exact assembly designed for your burner.
