316536610 frigidaire Ignitor/Orifice Assembly is a combined ignition and gas metering subassembly designed for use in Frigidaire gas cooking appliances. As a service replacement component,it integrates an ignitor element with a matched orifice that together initiate combustion and control the fuel flow to an individual burner or burner group.
Within the appliance the assembly serves two primary functions: producing the ignition source (spark or hot-surface heat,depending on the design) and restricting the gas flow to the intended rate via the orifice. It interfaces directly with the appliance gas manifold and valve, the burner headand the ignition control circuitry or moduleand its performance affects flame stability, combustion efficiency and safety systems that rely on consistent ignition and flame sensing.
In this article readers can expect a technical overview of the assembly’s function, guidance on model and compatibility considerations, the common symptoms that indicate failureand diagnostic checks a technician might use (electrical continuity, ignition voltage checks, visual spark/ignition inspection and gas flow verification). The article will also cover practical replacement considerations such as correct orifice sizing, sealing and mounting best practicesand final leak and operation checks required to restore safe, reliable appliance operation.

Functional Role of the Ignitor/Orifice in Burner Ignition and Gas Flow Control
The 316536610 Frigidaire Ignitor/Orifice Assembly combines a precision gas metering orifice with an ignition electrode to both regulate fuel flow and initiate combustion at a surface burner. The orifice is a fixed restriction that, together with the appliance manifold pressure, determines the gas mass flow and thus the burner’s BTU output and flame shape; the ignitor provides the electrical energy (spark) required to ignite the air-fuel mixture at the burner ports. correct function depends on matching the orifice size to the household gas type (natural gas or LP),ensuring the ignitor electrode gap and insulation are intact,and maintaining the proper mounting orientation so the spark is positioned relative to the gas jets for reliable ignition and stable flame propagation.
- Orifice control: sets flow rate and affects flame size and combustion characteristics.
- Ignitor behavior: gap condition, electrode wearor contamination changes ignition timing and reliability.
- compatibility: confirm gas type (natural vs LP), part number fitmentand manifold pressure before replacement.
- Failure symptoms: delayed ignition, continuous sparking, weak or yellow flame, sootor audible gas flow irregularities.
| Item | Description |
|---|---|
| Orifice | Calibrated aperture that meters gas at specified manifold pressure; determines BTU and flame geometry. |
| Ignitor electrode | Generates spark at the burner ports; requires correct gap, insulationand voltage to ignite reliably. |
| Service note | Verify model compatibility and gas type; avoid reaming or modifying orifices-replace with correct calibrated unit. |
For troubleshooting and maintenance, inspect the orifice for deposits or obstruction and check the ignitor for cracked ceramic, electrode erosionor loose wiring; cleaning with compressed air can remove debris, but a damaged orifice or electrode should be replaced. Technicians should confirm manifold pressure with a manometer and compare expected flow to the orifice specification before concluding the assembly is defective; swapping an assembly without matching orifice sizing or gas-type configuration can restore ignition yet leave the appliance operating outside intended performance or safety margins.
How the 316536610 Frigidaire Ignitor/Orifice Assembly Operates Within the Appliance Burner System
The 316536610 Frigidaire Ignitor/Orifice Assembly is an integrated burner component that combines a spark electrode with a precision gas orifice to initiate and control combustion at a stove burner. Mechanically it mounts at the burner head so the orifice aligns with the burner ports and the electrode tip is positioned to create a reliable spark across the ignition gap. Electrically the electrode receives low-voltage pulses from the range’s ignition module; when the control valve opens, gas flows through the orifice and is ignited by the spark. The orifice diameter determines the gas flow rate and, together with manifold pressure and burner geometry, defines flame size and shape, so correct orifice sizing is required for natural gas versus LP service and for cross‑model replacements.
- Primary functions: spark generation,gas metering,and positioning for consistent ignition.
- common failure symptoms: continuous clicking with no flame, small or yellow flame, delayed ignitionor intermittent lighting.
- Service considerations: verify orifice size and orientation, inspect/clean electrode tip and orifice passage, and check electrical continuity from the ignition module.
In practice, a technician should check both the electrical and gas-flow aspects when diagnosing problems: confirm the ignition module is delivering pulses to the electrode, measure electrode gap and conditionand inspect the orifice for clogging or incorrect sizing.Physical damage, a misaligned electrodeor a blocked orifice will cause weak or no flame even if the spark is present; conversely, an incorrectly sized orifice can produce excessive heat or poor combustion. Basic maintenance includes gentle cleaning of deposits from the electrode and orifice, securing proper mounting and clearancesand confirming compatibility with the appliance model and fuel type before installing a replacement.
| Item | Description |
|---|---|
| Electrode | Generates spark; position and tip condition affect ignition reliability. |
| Orifice | Precision orifice that meters gas flow; size varies by fuel type and required BTU. |
| Mounting/Orientation | Ensures alignment with burner ports and correct electrode gap to burner flame. |
| Compatibility | Replace with matching orifice size and connector type; verify model and fuel type before installation. |
Diagnostic Indicators and Common Failure Symptoms of the Ignitor/Orifice Assembly
The 316536610 Frigidaire Ignitor/Orifice Assembly combines the ignition element and the gas metering orifice into a single replaceable component that controls initial combustion and flame size for the appliance burner.Functionally, the ignitor either produces a high-temperature surface or an electrical spark to initiate gas combustion while the orifice restricts and shapes the gas flow to deliver the correct pressure and volume for the specified burner. Compatibility depends on manifold pressure, burner sizing and cabinetry clearances; technicians should verify appliance model numbers and manifold pressures against service literature before assuming interchangeability.
- Delayed ignition or repeated ignition attempts
- Weak, lifting or yellow/turbulent flame
- Visible soot, carbon buildup or flame instability
- No ignition despite power at the burner circuit
- Intermittent operation or physical damage to the ignitor tip/orifice
Diagnosing the assembly combines observation and basic electrical/gas checks: observe glow intensity and ignition time, listen for repeated valve clicks, inspect the orifice for deposits and check continuity of the ignitor circuit with a multimeter. A visibly dim or slow-to-glow ignitor with present line voltage usually indicates a degraded element that cannot draw sufficient current to open the gas valve; conversely, a luminous glow with no gas flow typically points to a clogged orifice or a downstream valve issue. Practical examples include a range that lights after several seconds (likely weak ignitor) versus burners that burn yellow or sooty (often restricted orifice or incorrect air/gas ratio). Replace or test components per the appliance service manual and document measured voltages and visual symptoms before ordering parts.
| item | Description |
|---|---|
| Delayed ignition | Weakened ignitor or reduced current draw causing extended warm-up time |
| Yellow or sooty flame | Partially clogged orifice or incorrect air/gas mixture; inspect and clean orifice |
| No continuity | Open ignitor element or broken lead; replace the ignitor assembly |
| Intermittent operation | Loose wiring, intermittent valve actuationor thermal cycling of a failing ignitor |
Replacement Considerations, Stepwise Installation Proceduresand Safety Precautions
The 316536610 Frigidaire Ignitor/Orifice Assembly integrates the spark or hot-surface ignitor with the matched gas orifice to control reliable ignition and consistent burner flame shape. This assembly governs the timing and energy of the ignition source and the calibrated gas flow through the orifice, so failure modes can present as no ignition, repeated sparking without light-off, weak or yellow flamesor uneven heat across a burner. Confirm electrical connector type, mounting flangeand orifice thread size against the appliance model before replacement; gas type (natural versus LP) requires the correct orifice or a certified conversion kit. Practical troubleshooting steps include verifying ignitor continuity or proper heater resistance per service manual, observing the ignition sequence under a controlled testand comparing flame characteristics to a known-good burner to isolate whether the ignitororificeor upstream regulator is at fault.
- Shut off gas and electrical power before any disassembly.
- Document wire locations and take reference photos to ensure correct reconnection.
- Replace gaskets and use thread sealant rated for gas on pipe threads when applicable.
- Tighten fasteners to light torque values to avoid distorting the assembly; avoid overtightening or misaligning the electrode.
- Perform a leak test (soapy water or approved detector) and verify steady blue flame on initial light-off.
| Item | Description |
|---|---|
| Request | Ignition and flow regulation for compatible Frigidaire gas ranges and cooktops |
| Common symptoms | No ignition, repeated sparking, weak or unstable flame |
| Checks before replacement | Model cross-reference, connector type, gas type (Natural/LP), electrode gap per service spec |
Follow a methodical installation: isolate utilities, remove the old assembly while preserving mounting hardware, inspect the burner bore and valve seat for debris, fit the new assembly in the same orientationand reconnect electrical leads to their recorded positions. After reassembly, restore gas and power and observe several ignition cycles; a correctly installed assembly will produce an immediate, consistent flame and stop sparking once flame is established. Maintain basic safety controls: ventilate the area, wear eye protection, do not use open flames during leak checksand engage a licensed technician for any regulator adjustments, manifold workor gas-type conversions beyond simple plug-and-play replacement.
Q&A
What appliances use Frigidaire part 316536610 (Ignitor/Orifice Assembly)?
Part 316536610 is an OEM ignitor/orifice assembly used on a range of Frigidaire-built gas cooktops and ranges (and sometimes models branded Kenmore, Electrolux or others that share Frigidaire components).Compatibility depends on the appliance model number – always verify the part number against your appliance’s model/parts list before ordering.
What are the common symptoms that this ignitor/orifice assembly has failed?
Common signs include no spark/click when you try to light a burner, intermittent ignition, a weak or delayed sparkor gas flowing without ignition. For LP versus natural gas issues, you may also see an unusually large or small flame if the orifice size is incorrect or partially blocked.
How can I test the ignitor/orifice assembly to confirm it’s bad?
First, visually inspect the electrode for cracks, heavy carbon buildup or breakage and the orifice for clogs. with the appliance powered off and gas shut off, you can check the ignitor circuit for continuity with a multimeter (a broken electrode usually shows open circuit). To confirm ignition operation, restore power and briefly operate the burner while watching for a consistent spark (don’t do this if you smell gas strongly). If there is power to the ignition module but no spark and the electrode is intact, the assembly is likely defective.
Can I replace just the electrode or do I need to replace the entire 316536610 assembly?
Depending on the design, some electrodes are serviceable separately but many technicians prefer replacing the complete ignitor/orifice assembly because it ensures the orifice (gas metering) and electrode are correct and properly sealed. Replacing the whole assembly reduces leak risk and avoids geometry or sizing mismatches that can affect ignition.
Is this part diffrent for natural gas and LP (propane) ovens? How do I know I have the right orifice?
Yes – orifice size differs between natural gas and LP. The orifice in 316536610 must match your fuel type. The appliance manual or conversion kit will specify the correct orifice size; many cooktops shipped for propane have smaller orifices and sometimes are labeled.If you are converting fuel types,use the correct OEM conversion orifice or a certified conversion kit and follow the manufacturer’s instructions or hire a qualified technician.
What safety precautions should I take when replacing this assembly?
Turn off the gas supply and unplug the appliance before working. Work in a well-ventilated area and avoid open flames. After installation,check for gas leaks at fittings with a soap-and-water solution (bubbles indicate a leak) or a suitable gas leak detector. If you smell gas at any time,stop,ventilate,evacuate if needed,and contact a qualified technician or your gas utility. If you are not pleasant working on gas appliances, hire a licensed technician.
Any tips for installation – alignment, gap, torqueor thread sealant?
Make sure the electrode is positioned and aligned exactly as the original so the spark reaches the burner flame area; a misaligned electrode often prevents ignition. A typical spark gap is small (a few millimeters) but follow the manufacturer specification if available. Install the orifice/assembly finger-tight and than to the manufacturer’s recommended torque – avoid over-torquing metal gas fittings. Use only gas-rated thread sealant where required (do not use ordinary Teflon tape on some small orifices unless the manufacturer specifies it). After installation,test each burner for correct ignition and check for leaks.
I replaced the assembly but the burner still won’t light – what should I check next?
if the new assembly is installed correctly but ignition still fails, check the ignition module/spark generator, wiring harness and burner switch for power and continuity.Ensure the spark wire connection is secure and that the burner cap and head are seated correctly (mis-seated parts can block spark). If burners light but flame is unstable or too large/small, recheck orifice size and fuel type. When in doubt, call a qualified service technician to diagnose electronic ignition or gas-supply issues.
